Recently, a reader asked me about the dangers that pets can face around the house. So, I visited my local animal 26 last weekend and got some advice to share about how we can make our homes 27 for our pets.When I arrived, several pets and their 28 were in the waiting room. M r. Smith, with a cat, chatted with me. “My cat will be 29 for an uncomfortable stomach in a minute,”he said. “My children gave 30 a bowl of milk. However, if she is given milk, she will get astomachache.”Just then, the vet walked over to us. “Yes, Mr. Smith is 31 . Only a few people know this, but milk mustn’t be fed to cats 32 some cats can’t take it in easily,” the vet said. “Other human foods are bad for pets 33 . For example, if a dog eats chocolate, it will become34 .”I asked the vet what other 35 there are for pets around the house. “Well,” she replied, “we should not 36 small things, such as batteries, lying around as they can be eaten by pets. Last month, a small cat was brought 37 because it had eaten a button which was on the floor without being noticed.”Before I left, the vet 38 me some more important advice to share with you:You should keep all medicines and cleaning products away from pets.

A"How many common English words were invented by Shakespeare?”How long did it take people to find the answer to this question 15 years ago? And now!you can google it and find the answer immediately!Google is the most popular internet search engine in the world. It was invented by two students, Larry Page and Sergey Brin. They met in 1993, when they were studying computer science at Stanford University, USA. They dreamed of producing something that could also answer any question in seconds.Internet search engines at that time were slow and gave many websites that weren’t useful. In January 1996, Page and Brin decided to make a better and faster search engine. They thought the results should be based on the most popular websites.Nobody would give them money for their projects, so they used their own money. They also borrowed money from family and friends. Then, in 1998, they were given a cheque for $100,000,and they started their own company. Their first office was in a friend’s garage. The company’s name is Google, a word which comes from mathematics. A “google” is a very high number ---- 1 followed by a hundred zeros.The google search engine was soon used by thousands of people worldwide because it was fast, easy and correct. By 2002 it was the biggest search engine on the Internet. Now, more questions have been answered by Google than any other Internet service, from sport to science, and from music to medicine. Google hopes that in the future all the world’s information will be put on the Internet, so that everybody can find everything.41. Why did the writer begin this passage by asking you a question?A. Because he or she liked to begin this passage by asking readers a question.B. Because he or she was afraid that the readers didn’t know this question.C. Because he or she wanted to make the readers interested in this passage.D. Because Shakespeare is one of the most famous people in the world.42. The underline word “cheque” in the fifth paragraph means .A. 楼房B.账单C.订单D.支票43. From the passage we know that at the beginning of the their project, .A. there was not any search engine on the Internet.B. nobody supported them except their family and friends.C. Larry Page and Sergey Brin dreamed to answer any question.D. one of the most popular websites gave them a cheque for $100,000.44. Which statement is NOT true according to the passage?A. Now the Google search engine is widely used in the world.B. The google search engine was not the biggest one before 2002.C. Larry Page and Sergey Brin named google after a hundred zeros.D. The service of the Google search engine is very popular.45. The passage mainly tells us .A. the development of the Google search engine.B. about Larry Page and Sergey Brin.C. how to find information on the Internet.D. how to use Google search engine.BIt’s time for school! But on May 14th, 170 students at Duncanville High School in Texas, US, were told to go back home.Why? Because they were wearing the wrong clothes to school.Schools in the US don’t always ask students to wear uniforms. But they have dress codes(着装要求). For example, Duncanville High School tells students to wear belts, shirts without logos(标识).Schools’ most-hated clothes are different.In 2011, the saggy(松垮的)trousers law was passed in Florida. It stops students from wearing trousers that show body parts.Now, “the favourite new target(目标) of the school dress code” is leggings(紧身裤), reported the Associated Press. Some schools don’t allow leggings. Other schools ask students to wear a shirt or a skirt over leggings.Some students complain(抱怨)that schools are going too far. But schools say dress codes help protect students’ safety and make sure they grow up with good taste.“We want to teach them that they must meet the expectations(期望) not only here in school, but also outside school,” said Andre Smith.46. What happened to 170 students at Duncanville High School on May 14th?A. They were told to go back home.B. They were wearing the uniforms to school.C. They followed the school dress codes.D. They didn’t know it was time for school.47. In Duncanville High School, students are allowed to wear .A. the wrong clothesB. belts, shirts without logos.C. their favourite clothesD. school’s most-hated clothes.48.How long has the saggy trousers law been used in Florida?A. For a few weeks.B. For several months.C. For two years.D. For three years.49.Some students complain that schools are going too far probably because .A. they want to grow up with good tasteB. they want to protect themselvesC. they are not happy with the rulesD. they are interested in skirts over leggings50. We can infer(推断)from the text that Andre Smith may be .A. the head of Duncanville High SchoolB. a student from Duncanville High SchoolC. the head of the Associated PressD. a news reporter from the Associated PressCAlmost all cultures celebrate the end of one year and the beginning of another in some way. Different cultures celebrate the beginning of a new year in different ways, and at different times on the calendar.In Western countries, people usually celebrate New Year at midnight on December 31st –January 1st. People may go to parties, sometimes dressed in formal(正式的)clothes, and the may drink champagne(香槟) at midnight. During the first minutes of the new year, people cheer and wish each other happiness for the year ahead. But some cultures prefer to celebrate the new year by waking up early to watch the sun rise. They welcome the new year with the first light of the sunrise.Many cultures also do special things to get rid of(摆脱) bad luck at the beginning of a new year. For example, in Ecuador, families make a big doll from old clothes. The doll is filled with old newspapers and firecrackers. At midnight, these dolls are burned to show the bad things from the past year are gone and the new year can start afresh(重新). Other common traditions to keep away bad luck in a new year include throwing things into rivers or the ocean, or saying special things on the first day of the new year.Other New Year traditions are followed to bring good luck in the new year. One widespread Spanish tradition for good luck is to eat grapes on New Year’s Day. The more grapes a person eats, the more good luck the person will have in the year. In France, people eat pancakes for good luckat New Year. In the United States, some people eat black-eyed peas for good luck-but to get good luck for a whole year you have to eat 365 of them!51. The reading is mainly about .A. the meaning of “Happy New Year!”B. several different New Year traditionsC. what to eat on New Year’s DayD. why people dress up nicely on New Year’s Day52. It’s clear that .A. some cultures celebrate New Year in the morningB. the Western people celebrate New Year only on New Year’s DayC. people in Ecuador go to parties on December 31 st-January 1st.D. no cultures do special things to celebrate New Year53. In some cultures, people throw things into rivers or oceans to .A. bring good luckB. keep away bad luckC. forget everythingD. plan for the next year54. To have a happy new year, .A. friends talk to each other in special ways.B. families make big dolls filled with old clothesC. some people get up early to watch the sunriseD. Europeans eat 365 grapes on New Year’s Day55. When eating black-eyed peas on New Year’s Day, people think .A. one pea brings one day of luckB. black-eyed peas are the best medicineC. the peas are too black and taste badD. the peas are helpful to count numbers第二节:请先阅读下面短文,掌握其大意,然后根据短文内容从下面方框内的七个选项中选择五个还原到文中,使短文意思通顺,结构完整,并在答案上将其序号涂黑。
