Saturday, March 24th

We have arrived in the hot, wet city of Bangkok. This is our first trip to Thailand(泰国). All the different smells make us want to try the food. We are going to eat something special for dinner tonight. The hotel we are staying in is cheap, and very clean. We plan to stay here for a few days, visit some places in the city, and then travel to Chiang Mai in the North.

Tuesday, March 27th

Bangkok is wonderful and surprising. The places are interesting. We visited the famous market which was on water, and saw a lot of fruits and vegetables. Everything is so colorful, and we have taken hundreds of photos already! Later today we will leave for Chiang Mai. We will take the train north, stay in Chiang Mai for two days, and then catch a bus to Chiang Rai.

Friday, March 30th

Our trip to Chiang Rai was long and boring. We visited a small village in the mountains. The village people here love the quiet life—no computers or phones. They are the kindest people I have ever met. They always smile and say “hello”. Kathy and I can only speak a few words of Thai, so smiling is the best way to show our kindness. I feel good here and hope to be able to come back next year.

Do you know of anyone who uses the truth to deceive(欺骗)? When someone tells you something that is true,but leaves out important information that should be included, he can give you a false picture.

For example,someone might say, “I just won a hundred dollars on the lottery(彩票). It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”

This guy's a winner,right? Maybe,maybe not.We then discover that he bought $ 200 worth of tickets,and only one was a winner.He’s really a big loser!

He didn’t say anything that was false,but he left out important information on purpose.That’s called a half-truth.Half truths are not technically lies,but they are just as dishonest.

Some politicians often use this trick.Let’s say that during Governor Smith’s last term,her state lost one million jobs and gained three million jobs.Then she seeks an other term.One of her opponents(对手)says,“During Governor Smith’s term,the state lost one million jobs!” That’s true.However,an honest statement would have been,“During Governor Smith's term,the state had a net gain of two million jobs.’’

Advertisers will sometimes use half—truths.It’s against the law to make false statements so they try to mislead you with the truth.An advertisement might say,“Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.”It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.

This kind of deception happens too often.It’s a sad fact of life:Lies are lies,and sometimes the truth can 1ie as well.

41. How much did the lottery winner lose?

A.one hundred dollars.B.Two hundred dollars.

C.Three hundred dollars. D.Four hundred dollars.

42. We may infer that the author believes people should ________.

A.buy lottery tickets if possible B.make use of half—truths C.be careful about what they are told D.not trust the Yucky Company 43. What do the underline words “net gain”in Paragraph 5 mean?

A. final increase

B. big advantage

C. large sha

re D. total saving

44. Which of the following is true according to the passage?

A.Using half truths is against the law.

B.Technically,half truths are in fact lies.

C.Yucky Pills is a very good medicine for toothache.

D.Governor Smith did a good job during her last term.

45. Which of the following best expresses the main idea of the passage?

A.He’s really a b ig loser!

B.Sometimes the truth can lie as well.

C.Advertisers will sometimes use half truths.

D.It’s against the law to make false statements.

C

At first, the earth’s surface(表面) layer (层) was made up of huge blocks of hard, solid rocks. Then slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebbles (卵石) and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil. There are many ways in which large pieces of rock break into smaller ones. Wind, water. heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and cracks (裂缝) in the rock, which become bigger and finally the rock breaks up into smaller pieces.

The moving water of streams and rivers also helps to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones. Thus, the larger rocks are worn down to smaller pieces.

The heat of the sun is also helpful to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the carcks can turn into ice in cold weather. As this happens, it becomes bigger and the cracks become wider, and finally break into smaller pieces.

46. According to the passage, soil____________ .

A. forms very slowly

B. is a mixture of stones, pebbles and sand

C. makes up the layers of the earth

D. is becoming smaller and smaller

47. How many factors are mentioned in helping break up rocks?

A. Three.

B. Four.

C. Five.

D. More than five.

48. Which of the follwing speeds up(加速) the breaks of rocks most?

A. Hot weather.

B. Cold water.

C. Sharp changes in temperature.

D. More dead plants in the cracks.

49. Which of the following is NOT true?

A. The remains of many plants and animals formed soil.

B. If a large rock never moves, it will never break up.

C. Even if a large rock never moves, it will break up.

D. Ice in the cracks helps to break up rocks.

50. The best title for this passage should be____________ ?

A. Soil From Rocks

B. Ways to Break up Rocks

C. Soil on the Earth

D. Soil, Outmost Layer of the Earth

D

Scientists in Mexico have just begun a new study of one of the world’s biggest pyramids—the Pyramid of the Sun, north of Mexico City. They’re putting lots of small, high-tech machines under the pyramid to try to unlock some of its secrets. For thousands of years, people have tried to uncover the secrets of the pyramids.

The people who built the pyramids made lots of secret doors and rooms to stop tomb raiders from finding the treasures inside. However, there always have been some smart thieves in history. Now, almost all of Egypt’s pyramids have been robbed, including the Great Pyramid of Khufu, which is the largest pyramid in the world. It is the only one of the ancient wonders of the world that is still standing.

In 820 AD, an Arab king named Abdullah AI Manum got a group of workers to dig their way into the Great Pyramid and have a look. Inside the pyramid, they found three rooms—the Queen’s Chamber, the Grand Gallery and the King’s Chamber. But

to their surprise, the men didn’t find treasures they wanted. The Queen’s and King’s Chambers were both empty! Where were the King’s mummy and his treasures? Had someone already ta ken them away? The huge stone doors at the pyramid’s entrance were still closed when AI Manum’s men went inside. How had the thieves got in and out?

Since then, many people have gone inside the Great Pyramid to have a look or to try to take things. But still, no other chambers or walkways have been found.

In 2002, an American team made the most recent visit to the Great Pyramid. Scientists sent a robot into the pyramid, but they only found a mysterious locked stone door.

51. We can learn from the passage that ________.

A. scientists have already studied the Pyramid of the Sun for thousands of years

B. all the pyramids have been broken into except the Pyramid of the Sun

C. the Pyramid of the Sun was built by the ancient Arabians

D. the Pyramid of the Sun is not in Egypt

52. The first two paragraphs were written to show that ________.

A. the Pyramid of the Sun is an unusual historical building

B. ancient Egyptian kings and queens were cruel

C. construction workers led a hard life in ancient Egypt

D. the secrets of some pyramids remain to be uncovered

53. What is the purpose of making some secret doors to the pyramids?

A. To try to unlock some of their secrets.

B. To stop robbers from finding the treasures inside.

C. To make the dead kings come into power again.

D. To make the pyramids mysterious.

54. Which of the following is NOT true about the Great Pyramid of Khufu?

A. It is the largest pyramid in the world.

B. It is the only one of the ancient wonders of the world that exists.

C. People think AI Manum took the king’s mummy and treasures away.

D. Scientists found a mysterious locked stone door to the Great Pyramid.

55. What would be the best title for the text?

A. The Pyramid of the Sun

B. The secrets of the Great Pyramid

C. Unlocking the Mystery of Pyramids

D. A Mysterious Locked Stone Door

根据短文内容填空。

[1]Five years ago, David Smith wore an expensive suit to work every day. “ I was a clothes addict”. He jokes. “I used to carry a fresh suit to work with me so I

co uld change if my clothes got wrinkled”. Today David wears casual clothes-khaki pants and sports shirt to the office. He hardly ever wears a necktie. “I’m working harder than ever”. David says, “and I need to feel comfortable”.

[2]More and more companies are allowing their office workers to _________ in the United States. The change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday. This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a –week benefit for employees has really become an everyday thing.” Said business consultant Maisly Jones.

[3]Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “Many young people don’t want to dress up for work”, says the owner of a software company, “so it’s hard to hire people if you have a conservative dre ss code”. Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study 85 percent of employers said that they believe that casual dress improves employee motivation. Only 4 percent of employers said that casual dress has a negative influence on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “ Suits are expensive, if you have to wear one every day”, one person said”, For the same amount of money, you can buy a lot more casual clothes”.

56.Why does David Smith wear casual clothes now?(no more than 8 words)

_____________________________________________________________________

57. List three advantages of casual office wear according to the text?(no more than 10 words)

陕西省2020学年高一语文寒假作业3

高一假期作业 一、阅读下面的文字,完成1~3题。(每题3分,共9分) 中国诗歌自身的调节功能 中国诗歌之所以能历久而不衰,一个重要的原因是它本身有一种调节功能,其语言形式处在不断变化的过程之中。从四言到五言到七言,随着汉语的发展变化而不断形成新的节奏。二二节奏的四言诗是诗歌的早期形式,随着《诗经》时代的结束而趋于僵化。此后的四言诗,如曹操《短歌行》那样的佳作实在不多。中国诗歌主要的形式是二三节奏的五言和四三节奏的七言。四言诗一句分成均等的两半,节奏呆板。五七言前后相差一个音节,寓变化于整齐之中,节奏活泼。所以五七言取代了四言而成为中国诗歌的主要形式。为什么七言没有继续加长,发展为九言呢?我想这是因为一句诗七个音节已经达到读起来不至于呼吸急促的最大限度,加长到九言读起来呼吸急促。这样的诗行不容易建立起来。 在音节变化的同时,格律也在逐渐严密化。中国诗歌是从自由体(古诗)走向格律体(近体诗),但格律体确立之后自由体仍不衰退,而是和格律体并存着,各有其特长。就一个诗人来说固然有的擅长自由体,有的擅长格律体,但两方面的训练都是具备的。在自由体与格律体之间始终没有分成派别。它们互相补充又各擅其能,共同促使中国诗歌的繁荣发展。 从深层考察,诗歌的发展乃是性情与声色两种因素的交互作用。从重性情到重声色,是中国诗歌史的第一个转变,这个转变发生在晋宋之际,具体地说是在陶谢之间。这恰好也正是近体诗的各种技巧被自觉加以运用的时候。明代的陆时雍说:“诗至于宋,古之终而律之始也。体制一变,便觉声色俱开。谢灵运鬼斧默运,其梓庆之鑢乎?”具体地说,这个转变主要表现在两个方面,即从重写意转到重摹象,从启示性的语言转向写实性的语言。《文心雕龙·明诗篇》说:“俪采百字之偶,争价一句之奇;情必极貌以写物,辞必穷力而追新。”指出了转变后的状况。从陶到谢的转变,反映了两代诗风的嬗迭。正如沈德潜《说诗晬语》所说:“诗至于宋,性情渐隐,声色大开,诗运转关也。”重声色的阶段从南朝的宋延续到初唐,一方面丰富了表现技巧,另一方面也建立起严密的格律,到盛唐,性情与声色完美地统一起来,遂达到了诗歌的高潮。 但是性情与声色的统一毕竟不能维持多久。盛唐半个世纪一过,二者便又开始分离。重性情的,声色不足;求声色的,性情不完。此后二者统一的诗作虽然不少,但能以二者的统一维持一个时代的再也没有了。中国诗歌史总的看来是绚丽多彩的,但其最引人瞩目的顶峰也不过只有这么一个盛唐,半个世纪而已。 1.下列对中国诗歌自身“调节功能”的理解,不正确的一项是() A.语言形式的调节功能还体现在格律的逐渐严密化:格律体取代了自由体。 B.其语言形式的调节功能体现在不断形成新的诗句节奏:五七言取代了四言成为主流。 C.“调节功能”是指历久不衰的中国诗歌在其发展过程中不断求变的一种特性。 D.调节功能还体现在性情与声色的交互作用,从而使中国诗歌呈现出不同的风貌。2.下列表述完全符合原文意思的一项是() A.随着人们对《诗经》兴趣的降低,《诗经》的时代结束了,人们由此感觉到二二节奏的四言诗越来越僵化。 B.中国诗歌没有从五言七言发展成九言,是因为五言七言寓变化于整齐之中,节奏更为活泼的缘故。 C.明代的陆时雍和《文心雕龙·明诗篇》都指出了两代诗风的嬗迭发生在陶渊明和

Once I decided to climb a mountain and asked my uncle for advice. He said, “Unfortunately, I am so busy these days. But if no one leads, you are likely to be lost. ” I said, “What am I afraid of? If lost, I will call you for help. ” He said with a smile, “Well, I hope you will not get lost. Good luck. ” I confidently said, “I think I’ll certainly be able to return safely.” I finally set off by myself. Everything was very smooth at first. When I came close to the top, a sudden strong wind burst. I had to find a shelter to hide my sleeping bag inside. An hour later, I crawled(爬)out and looked around. All the places were so familiar and those roads appeared to extend(延伸)in all directions. What should I do? I decided to call for help, but except the sleeping bag, there was nothing left. Going on in my despair(绝望), suddenly I found a map from the sleeping bag. Could that be put by Uncle? Anyway, I followed the directions on the map and succeeded in finding a smooth way home. Stepping into the house, I was pleased to see Uncle again and said excitedly, “Today, thanks to your map, or I really could not return home. My baggage, including my mobile phone, was blown away. ” Strangely Uncle asked, “The map?” I said, “The one you put in my sleeping bag.” Seeing the map, Uncle suddenly laughed again, “This is your 4-year-old cousin Linda’s painting of a Super Spider-Man.” I was surprised, “However, I really got this ‘map’ to find it down the road.” Uncle said, “You can come down the mountain successfully, not due to the map,

Fire!” What terrible words to hear when one wakes up in a strange house in the middle of the night! It was a large, old, wooden house and my room was on the top floor. I jumped out of bed, opened the door and stepped outside the house. There was full of thick smoke. I began to run, but as I was still only half-awake, instead of going towards the stairs I went in the opposite direction. The smoke grew thicker and I could see fire all around. The floor became hot under my bare(赤裸的)feet. I found an open door and ran into a room to get to the window. But before I could reach it, one of my feet caught in something soft and I fell down. The thing I had fallen over felt like a bundle(包袱)of clothes, and I picked it up to protect my face from the smoke and heat. Just then the floor gave way under me and I crashed to the floor below with pieces of burning wood all around me. I saw a doorway in fire, then I put the bundle over my face and ran. My feet burned me terrible, but I got through. As I reached the cold air outside, my bundle of clothes gave a thin cry, I nearly dropped it in my surprise. Then I was in a crowd gathered in the street. A woman in a night-d ress and a borrowed man’s coat screamed as she saw me and came running madly. She was the Mayor’s wife, and I had saved her baby. 1. When the fire arose in the middle of the night, the author was _______. A. at home B. sleeping C. sitting in bed D. playing games 2.The author saved the baby _____. A. because he was very brave. B. because he liked the baby very much. C. because he just happened to save it. D. because it was t he Mayor’s baby. 3. He ran in the wrong direction because he _______.

2019年重庆市永川三中高一英语寒假作业(八)

高一英语寒假作业 I.阅读理解 阅读下列短文,从每题所给的四个选项(A、B、C 和D)中,选出最佳选项. A I have a story about raising free-range (自由放养) kids. This past Columbus Day, my husband and I went fishing with some friends on their boat while our10 and 8-year-old kids were in school. We left the house all at the same time, about 7 a. m. My children walked to and from school every day and we knew they would be OK for a couple hours by themselves anyway. We told them to go home after school and we would be home around 4 p. m. We live on the Gulf Coast, and since it was a beautiful day, all of the adults decided to go fishing off-shore. At around 2 p. m. after a good harvest from the sea, we started back to the shore and unfortunately after some time, we ran out of gas. We were out of cellphone service, and what was even worse was that 911 wasn’t working. We didn’t have a radio either. Therefore, we were stuck waiting for someone to pass by. We were out there until 10 p. m. All the while my children were at home, expecting us to return shortly after they got home. At about 7 p. m. , when it was getting dark, my 10-year-old daughter thought something might be wrong so she walked to each house on the street until someone answered the door and asked the person what they should do. This was how we were finally found by the game warden (管理员) on the coast and “rescued”. Talking with that neighbor the next day, I was never so proud of my children. This neighbour explained to me, “What calmness both of your children showed when explaining the situation and how im pressed I was with your children seeking help, even though they didn’t know me.” I never doubted him for a minute, though next time we go fishing we’ll monitor the gas more carefully. 1.What did the author probably feel at the very start of returning to the shore? A Anxious. B. Frightened. C. Pleased. D. Disappointed. 2.Why couldn’t the parents call their children when going back to the shore? A. They didn’t carry a radio. B. Their boat was out of gas. C. They believed in their children. D. There was no phone signal there. 3.What was the author’s reaction to his neighbor’s words? A. He thanked his neighbor. B. He was not surprised. C. He didn’t agree with his neighbor. D. He needed to think for himself. 4.What is the best title for the text? A. Stuck on the Sea B. A Brave Girl C. A Thrilling Experience D. Lost at Sea B Painkillers (止痛药) are turning out to be a real pain: according to a new study in the British Medical Journal. Taking them for just a week can increase your risk of heart attack by 50%. The research suggested that the risk related to the use of certain drugs was greatest with higher doses (服用量) and during the first month of use. The potential risk may increase by 75% for medicines like ibuprofen (布洛芬) and naproxen, and more than 100% for rofecoxib. It all sounds bad but, your risk is very low, — say, one in a million — a 100% increase means
