Unit 4 Earthquakes课时作业I •阅读理解A(2019 •邯郸模拟C)Have you ever noticed tiny raised areas on the branches of atree ? These may have bee n in sects.These small in sects feed on tree sap(汁液).In sects on urba n trees are no tably more abundant tha n those on rural trees.As a result , urban trees suffer from heavy infestations(害虫横行),and are often unhealthy or die.To protect and restore urban trees' health , we need to determine the factorsthat make these tree pests more successful in urba n habitats.Livi ng orga ni sms in teract closely with their environmen t.The warmer, more drought -stressed trees harbor more successful pests than cooler ,less drought -stressed trees.As cities and natural habitats become hotter and drier ,damaging insects will become more abundant on urban trees.Trees within urban forests are valuable economically and for the environmental sustainability(可持续性)of the region.More than half of the world's population lives in cities.Across the globe ,people are moving into cities at a faster ratethan ever.Rapid growth may turn cities into places with harder conditions.Although cities are primarily made of buildings ,roads ,parking lots ,and vehicles ,thereare still plants in them.The trees within a city are referred to as the urban forest.Urban forests offer very big benefits to humanand environmental health.They improve air and water quality ,provide habitat for wildlife ,cool down temperatures and beautify our environment.They make cities livable.However,being a city tree is not easy.Heat released by humanactivities is trapped in cities.As a result ,temperatures in urban areas are often warmer than theirsurrounding rural areas.We call this urban warming or the urban heat island effect.Urban habitats are mostly made of surfaces of asphalt(沥青)and concrete.These surfaces reduce the amount of rainwater that reaches tree roots.As a result ,urban forests may suffer ,which can negatively affect people and theenvironment.What can we do to restore urban forests ?Regular irrigation when possible mayhelp keep pest populations under control.Planting tree species that are suitable to handle heat and drought stress would also reduce the occurrence of insect pest outbreaks.【语篇解读】本文主要介绍了城市中的森林使城市宜居,但是人类的活动对城市的树木产生了极大的影响,所以我们应该为保护城市树木采取行动。

专题04 Earthquakes第一节阅读理解AAfter the earthquake had stopped, when the rescuers reached the ruins of a young woman's house, they saw her dead body through the cracks. But her pose was somehow strange that she knelt on her knees like a person was worshipping(礼拜); her body was leaning forward, and her two hands were supported by an object. The collapsed house had crashed her back and her head.With so many difficulties, the leader of the rescue team put his hand through a narrow gap on the wall to reach the woman's body. He was hoping that this woman could be still alive. However, the cold and stiff body told him that she had passed away for sure.He and the rest of the team left this house and were going to search the next collapsed building. For some reasons, the team leader was driven by a compelling force to go back to the ruined house of the dead woman. Again, he knelt down and used his hand through the narrow cracks to search the little space under the dead body. Suddenly, he screamed with excitement,“A child! There is a child!”The whole team worked together; carefully they removed the piles of ruined objects around the dead woman. There was a 3monthold little boy wrapped in a flowery blanket under his mother's dead body. Obviously, the woman had made a sacrifice for saving her son. When her house was falling, she used her body to make a cover to protect her son. The little boy was still sleeping peacefully when the team leader picked him up.The medical doctor came quickly to examine the little boy. After he opened the blanket, he saw a cell phone.There was a text message on the screen. It said, “If you can survive, you must remember that I love you.” This cell phone was passed around from one hand to another. Everybody that read the message wept. “If you can survive, you must remember that I love you.” Such is the mother's love for her child!【文章大意】本文是一篇记叙文。

Unit 4 Earthquakes李仕才***阅读理解At 23, my career got going. I was midway through a master’s degree at the London School of Economics and Political Science and had been hired as a part­time reporter for a finance webs ite. I got a great one­month review and m y boss asked if I was interested in staying at the company after graduation.However, balancing graduate studies with work was challenging. To deal with it, I checked my real self at my office door. I came in to work, greeted my colleagues and listened more than I contributed in each morning meeting. The small team I worked with often seemed busy, so rather than giving ideas that might get turned down,I stayed back.After four months, my boss called me into his office. The meeting was going well until he told me that despite the great work I had produced, the team had held a meeting and decided,“We don’t think it’s the right fit.”I must have looked confused. “You’re ambitious, intelligent and will be very successful,” my boss said. “But you haven’t made enough effort to join the team. You lost the enthusiasm you showed in your interview. That won’t work long term,and if I could give you one piece of advice, it would be to get your guard down.”I couldn’t believe that performing well at my job wasn’t enoug h to keep it. But I knew my boss was right. They knew that when they hired me, I had no experience in finance reporting, yet they took a chance on me. In meetings I usually contributed last, after I had h eard everyone else’s suggestions. I did it to show t hat I was a listener, but also to hide my fears. They liked the person who walked into the interview, and they didn’t respect me when I hid that person from them.“Don’t leave before you leave.” That advice is essential for women at all stages of our careers. Because we work so hard for success, we don’t like to think that we hurt ourselves sometimes. But each of us must change when necessary. In trying to earn a full­time job, I “leaned back” in order not to show too much of myself or my lack of expertise(专门知识). I learned that the hard way wasn’t the way to achieve our goals.【解题导语】本文是一篇夹叙夹议文。

Unit 4 EarthquakesⅠ.阅读理解AAn earthquake is one of the most common natural disasters.It may cause great damage.So it is wise to learn some simple safety tips to protect yourself or your family members.Fragile items,like those made of glass are easily broken and should usually be placed on a lower surface,near the ground instead of placing them on cupboards higher up.Never place them near your bed,sofas and other furniture where you would be sitting or lying down.When there is strong movement,these pieces will fall to the floor directly and not on you.There is a strong chance of short circuits (短路) and fire breakouts during an earthquake.Make sure you turn off electrical connections and gas immediately when an earthquake happens.During an earthquake,lie beneath an object that is not easily damaged.Do not go near objects that could directly fall on you.Never use the elevator to go down.Stay inside until the shaking stops and it is safe to go outside.Research has shown that most injuries happen when people inside buildings try to go e the staircases at all times.If you are outdoors,do not take shelter under a tree,streetlights,electric poles or tall buildings.If you are driving,stop your car and stay in a safe place.Do not park your car under a tree or any tall object.If trapped in debris (瓦砾堆),cover your mouth with a handkerchief or clothing.Tap on a pipe or wall so rescuers can find e a whistle (哨子) if one is available.Never shout for help.Shouting can cause you to breathe in dangerous amounts of dust.Do not light a match because you may burn yourself.Do not move about or kick up dust.1.Which of the following is closest in meaning to the underlined word “Fragile”in Paragraph 2?A.Easily found.B.Easily broken.C.Expensive.D.Heavy.2.Where should the items made of glass be put to reduce the injury from the earthquake?A.On cupboards.B.On a lower surface.C.In the bedroom.D.Where children can’t reach them.3.What are people advised to do during the earthquake?A.Go out the building at once.B.Drive to a safe place quickly.C.Take shelter under a tree.D.Turn off electricity and gas immediately.语篇解读:地震是最常见的自然灾难之一,常造成巨大的损失。

Keep working? Get more exercise? Or learn something new? You may put them on hold. There’s a chance that, sooner or later, you might have to move further than you were thinking, as far as Mars (火星).On Thursday, National Geographic will show the first ever Mars show home, giving earthlings an idea of whattheir life could look like on the Red Planet. Set in the not­so­distant year of 2037, the igloo­shaped structure could be the home of your future.It shows a house built using recycled spacecraft parts and Martian soil, called regolith, which has been microwaved into bricks. Some parts of the home are recognisable—kitchen, bedroom—but there are fundamental differences that are vital for human survival.As the Martian atmosphere is around one hundredth as thick as the Earth’s, people will need permanent shelter from the sun and society will move largely indoors. Most buildings will be connected by underground passages and the houses won’t have windows. The homes will have simulatedsolar lighting, or natural light that has been bent several times.Walls will need to be 10 to 12 feet thick, to protect people from dangerous rays that can pass through six feet of steel, and a double air­locked entrance to keep the home under proper pressure.“We don’t think of our houses as things that keep us alive, but on Mars your house will be a survival centre,”says Stephen Petranek, author of How We’ll Live on Mars. This is not just the stuff of sci­fi. “Ten to twenty years from now there will certainly be people on Mars,”Petranek says.“We’ve had the technology for 30 years to land people on Mars, but we haven’t had the will,” Petranek says. “”’ participation has forced government agencies to up their game, and influential films such as Gravity and The Martian have caught society’s eye.【解题导语】本文主要对人类未来在火星上居住作了相关介绍.1.What can we know about the show home from the text?A.It has no windows or doors due to security concern.B.Its design presents the idea of environmental protection.C.It has thick walls keeping the home under proper pressure.D.Its underground passages connect all the buildings together.B 解析:推理判断题.根据第三段的第一句可推知,火星样板房的设计采用了可回收的宇宙飞船上的一些部件,体现了环保意识,故选B.2.What do the underlined words “put them on hold” in Paragraph 1 probably mean?A.Put them off. B.Give them away.C.Carry them through. D.Take them seriously.A 解析:词义猜测题.根据第一段的最后一句可推知,之前的列举都可能被搁置下来,而去火星居住迟早会成为可能,故选A.3.According to Petranek, what has sped up the process of sending people to Mars?A.The great influence of Mars show home.B.The development of related technology.D.The popularity of influential books on Mars.4.What is the best title for the text?A.Living on Mars: Possible or NotB.Sending People to Mars: Yes or NoC.First Ever Show Home: How Is It Made?D.Future Home on Mars: What Will It Be like?D 解析:标题归纳题.根据全文的整体内容可推知,本文主要对人类未来在火星上居住作了相关介绍,故选D.二、单句语法填空1.It had gotten very cold, and I guessed the good weatherwas an end.答案:at答案:ruins3.In the past ten years a number of high buildings (arise) where there was nothing but ruins.答案:have arisen4.(重庆卷)It was John who broke the window.

Unit 4 Earthquakes李仕才***阅读理解My mother grew up in a small coal mining town in southwest Iowa.My grandfather once told me that she knew no stranger and considered everyone in that community her friend.That attitude continued wherever she lived for the rest of her life.As a young girl, I felt embarrassed and cringed(畏缩) every time my mother addressed strangers in the grocery store or on the city bus.She talked to everyone and offered a smile.What really sold me on Mom’s approach to life was her experience on the senior bus, a story I’ve repeated to others many times.The weeks I could not be there, she used this low­cost transportation to the grocery store.After her first trip, I asked her how it went.“Ha!”she said, “I got on that bus and what did I see?Thirteen little old ladies and one old man, and not one word was spoken.”I wondered how long it would be until the somberness(忧郁的氛围) on that bus would change.On my next visit, Mom mentioned the ladies on the bus and something one of them had told her.“Oh, are you talking with them now?” I asked.“Of course, ”she said.“One day I climbed up the steps of the bus and before I looked for a seat, I gave them a big smile and I said, ‘Isn’t it a wonderful day?’ I noticed a few shy smiles.”Mom didn’t give up.She greeted them all each time she got on the bus and before long, the whole group was laughing and talking to one another.The bus became more than just transportation.She’s been gone for ten years but I’ve carried on her recipe for life.I smile at people as I walk by and often begin a conversation in the checkout line.Silent, solemn(严肃的) people respond with smiles of their own and a bit of chatter.All it takes is for one person to initiate(发起) the smile or greeting.It was I who had done the smiling first and all those people had responded.My mother didn’t lecture but taught me by example.She’d given me a recipe for life.【解题导语】本文主要讲述了作者的母亲积极乐观的人生态度对作者的影响。

A
People love cellphones,which is why nine in ten Americans own one.But does heavy use of cellphones pose a risk of cancer? This question has caused controversy for many years.A new study in rats nowaugmentsthose concerns.Its data linked long term,intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain.The results have yet to be confirmed,the authors note.
Phone signals are relayed between cell towers and cellphones via radio waves.This radio frequency—or RF— radiation is a type known as non ionizing(非电离的).Unlike X rays,non ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules,producing ions. So it tends to be far less harmful than ionizing radiation,such as X rays.But that does not mean radio waves might not cause harm.

Earthquakes李仕才【阅读理解】At present we spend a lot of time on our mobile devices these days and automakers have taken notes, rolling out connected cars that make it easy to do nearly everything from your phone.“We all enjoy those kinds of experiences where you want something and by the push of a button everything gets taken care of for you.You don’t have to go here and there and piece a bunch of things together by yourself. ”Ford recently introduced FordPass, a mobile platform that lets car owners access services like finding and paying for a parking spot.“Here’s the details of what charges will be in sign, and then I submit (点击接受), and then I receive a QRphoto allowing me entry access to that parking location. ”Over at Buick, the OnStar RemoteLink app connects owners to their cars no matter how faraway they are. “This car in Detroit, I could start from here in New York. Or let us say I have the only key to it and my wife in Detroit needs to get in the car, I can unlock it for her from here. ”The featu re harnesses the car’s 4G LTE connectivity (连接性). Up to seven mobile devices can connect to it at any given time.“We want people to feel as if they are at home within the car, which a lot of people want to be in just for the driving experience, now they can be in there as well, the passengers can be in there as well for the connectivity experience. ”But what does that connectivity mean for your privacy?“It is important to have personal information to create that individualized, personalized experience, but certainly it will be a customer’s option. ”For certain consumers, it may not even be an issue.“There certainly is a factor where a younger consumer is much more comfortable giving up a lot more privacy and data than an older consumer is, and more likely than not, you are going to see a similar behavior to how they handle their personal privacy within the vehicle. ”Considering how capable our mobile devices have become, perhaps the only question left to answer is: “Who’s driving? ”【文章大意】由于移动设备的广泛应用, 制造商推出了装配有车载移动设备的轿车, 进而可从事由智能手机发出指令的动作。

1. Which of the following helps the owner to unlock his car faraway?A. QRphoto.B. FordPass, a mobile platform.C. The Internet.D. OnStar RemoteLink app.【解析】选D。

细节理解题。

根据第五段最后一句可知A项是指允许车主进入停车位置、短文没提到C项, 因此A、C两项都不正确。

根据第四段可知B项是寻找停车场和支付停车费用的移动平台, 也不正确。

根据第六、七段可知D项是远程控制车辆的软件, 因此D项正确。

2. What does the underlined phrase “rolling out” mean?A. Moving by rolling.B. Leaving.C. Bringing out.D. Running.【解析】选C。

词义猜测题。

因此B项正确。
