第二部分阅读理解(共两节, 满分40分)
第一节(共15小题; 每小题2分, 满分30分)
A
I remember the first time I got on a horse. When I was a little boy aged two, my mom agreed to let me take a short ride and that was it! From then on, I drove my parents crazy begging for a horse.
When I was four, I had mutism, in which children stop speaking in certain social situations. I went days, weeks, months without a sound at school. At most, I might quietly whisper to a friend. I suffered silently through school until I was ten when a psychologist (心理学家) had an idea. He asked me what I wanted more than anything else in the world. He explained I was going to be given a chance to work for that. And I was permitted to whisper the answer in my mother’s ear, “A horse.”
I was to get a pony, but I had to live up to my end of the bargain (讲价). I had
a list of weekly tasks I had to finish. I had to answer the phone five times per week, something I had never done before. I had to say one word to my teacher at school and the list went on. For a child with mutism, saying one word to someone can be like climbing Mount Qomolangma. I did everything that was asked of me and the day came. His name was Sequoia, whom I fell in love with immediately. When I was in Sequoia’s presence, I forgot all about my problems and felt strong and secure.
I am a fully participating member of society these days. My horse and I made it through a master’s degree. I may have made it otherwise, but I’m not sure. I feel I owe my life to the horse and I try to give it back to him. He has given me the best gift I could ever imagine, my life.
21. What was the situation like when the author was four?
A. He didn’t say a word at all.
B. He learned how to ride a horse.
C. He found his classmates unfriendly.
D. He had difficulty in communicating.
22. What can we infer about the author from Paragraph 3?
A. He completed some tasks easily.
B. He pushed himself extremely hard.
C. He fell in love with Sequoia gradually.
D. He found the psychologist’s id ea useless.
23. What is the author’s purpose of writing the text?
A. To share his unfortunate childhood.
B. To give tips on how to cure mutism.
C. To show his deep gratefulness to his horse.
D. To encourage kids struggling against mutism.
B
Polish President Andrzej Duda has signed a bill into law that largely limits trade on Sundays, saying it will benefit family life.
The legislation (立法), worked out by the government and the Polish trade union, is expected to draw protests（反对） from large western supermarket chains that are the main target of the law. A large part of their profit is earned on weekends.
As of March 1, shops and markets are closed on two Sundays per month, in 2019
only one Sunday a month will be open for shopping; and starting in 2020, there will be no Sunday shopping with a few exceptions.
Duda praised the law as giving children a chance to be with parents and giving shop workers some needed time off. He also said big traders will need to adjust their practices to the new system and asked them for “understanding”. But critics say some of them make employees work long hours for modest（中等的） pay.
“A family should be together on Sundays,” Olszewska said after buying some food at a local Biedronka, a large discount supermarket chain. She said that before she retired she served cold cuts in a grocery store, and was grateful she never had to work on Sundays.
There are some exceptions to the ban. For instance, gas stations, cafes, pharmacies（药店） and some other businesses are allowed to keep operating on Sundays.
Anyone breaking the new rules faces a fine of up to 100,000 zlotys ($ 29,500), while repeat offenders（违反者） may face a prison sentence. Polish trade union appealed to people to report any violators to the National Labor Inspectorate, a state body.
24. Who will get some loss from the bill according to the passage?
A. The polish President Andrzej Duda.
B. Some large western supermarket chains.
C. All the markets in Poland.
D. Some common Polish families.
25. What can we infer from Paragraph 4?
A. Children had no time to play with their parents before.
B. Duda paid great attention to the shop workers.
C. Some workers will work extra hours on weekdays.
D. All the businesses will make adjustments to the bill.
26. What is the main idea of the passage?
A. Family life will be more important than shopping in Poland.
B. More and more western supermarket chains will leave Poland
C. The supermarket employees will have no job on Sundays in Poland.
D. Sunday shopping will be limited by the government in Poland.
C
Something Fun
A person is on trial for murder in a court room in Oklahoma. There is strong evidence indicating that he is guilty（有罪的）. However, the body is not found.
In the defense’s (辩护方) closing speech, the lawyer, knowing that his client (委托人) is guilty and that it looks like he’ll probably be seriously punished, decided to play a clever trick.
“Ladies and gentlemen of the jury (陪审团), I have a surprise for you all,” the lawyer says as he looks at his watch. “Within one minute, the person assumed dead in this case will walk into this court room,” he says and he looks towards the court-room door. The jury, somewhat surprised, looks at the door eagerly. A minute passes. Nothing happens.
Finally the lawyer says, “Actually, I made up the prev ious statement. But you all waited with expectation. I, therefore, put it to you that there is a reasonable doubt in this case as to whether anyone was killed and insist that you pass a judgment
of not guilty.”
The jury, clearly confused, back off to discuss.
A very few minutes later, the jury returned and one of them pronounces a verdict (裁决) of guilty.
“But how?” asks the lawyer in surprise. “You must have had some doubt; I saw all of you stare at the door.”
Answers the jury member, “Oh, we did look. But your client didn’t.”
27. Why was the person on trial according to the passage?
A. Because he couldn’t pay off the debts.
B. Because he probably killed somebody.
C. Because he didn’t pay the tax in time.
D. Because he planned to cheat the jury.
28. Why did the lawyer come up with the trick?
A. To find the body.
B. To frighten the jury.
C. To help his client.
D. To save himself.
29. Why did the jury look at the door eagerly?
A. The lawyer’s words must be true.
B. They expected his family to come in.
C. They were surprised and cheated by the lawyer.
D. They thought the person on trial was escaping.
30. What did the jury member’s answer mean in the last paragraph?
A. They firmly believed that nobody was killed.
B. The behaviour of the client gave him away.
C. The jury still needed more evidence to prove it.
D. The lawyer’s words were worth thinking about.
D
Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly, The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.
Certain microorganisms (微生物) cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release (释放) poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.
When people handle food properly, the risk of food poisoning is very small Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away
to have their stomachs emptied.
31. Which of the following statements is NOT true?
A. Food when poisoned can make people sick.
B. Food poisoning means death.
C. Food poisoning comes in varieties.
D. Food poisoning can be serious.
32. We know from the passage that the symptoms of food poisoning .
A. are always accompanied by a fever
B. are too common to be noted
C. can be noticed within hours
D. can be ignored
33. Food poisoning can be caused by all the following EXCEPT .
A. some chemicals
B. low temperatures
C. some tiny living things
D. certain natural materials
34. From Paragraph 5, we can learn that______
A. mushrooms should not be eaten
B. vegetables are safer than meat and seafood
C. natural poisons are more dangerous than chemicals
D. different types of food should be handled differently
35. It can be inferred from the passage that_________
A. natural materials are safe in food processing
B. chemicals are needed in food processing
C. food poisoning can be kept under control
D. food poisoning is out of control
第二节(共5小题; 每小题2分, 满分10分)
根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项。有两项为多余选项。
Diet Myths — Get the facts, or your diet may fail!
Dieting is hard work, and there are plenty of “helpful” diet tricks that can make weight loss even harder. 36
Carbs(含碳水化合物的食物) are bad for you. Carbohydrates are actually an important source of energy. There are good carbs and bad carbs. Some foods, like white bread or white rice, are example of bad carbs. Good carbs include whole wheat bread and brown rice. They’re rich in fiber and really good for you!
37 On the contrary, studies show that people who eat breakfast will eat fewer calories throughout the day. And if you know you’re goi ng to be eating a big meal later, don’t starve yourself in order to save you calories. You’ll just eat more during the meal because you’re so hungry! Instead, eat smaller meals a couple days before and after, and exercise more.
You can control where your body loses weight. Bad news – if you want a flatter stomach, just exercising your stomach won't work. 38 Cardio(有氧运动) exercises will help burn fat, while weight training helps build muscles. Your “trouble areas” might not be the first to slim down, b ut keep exercising!
Your weight depends on your genes. 39 While a “fat gene” does exist, its influence on your size is small. Smart eating and exercise have a much greater effect than your genes. Only 25 percent of your weight is controlled by genes – the rest is up to you.
Say “no”to junk food. Many people think that the key to losing weight is cutting out all bad foods. __40__ To lose weight and keep it off, eat great 80 percent of the time, but allow yourself in a treat or two the other 20 percent.
A. You can’t target where you lose weight.
B. But the more strict your diet is, the more likely you are to break it – and in a big way.
C. Here are some common myths about losing weight and the truth behind them.
D. Skipping meals helps you lose more weight.
E. If you and your family have problems with obesity, you’re not sure to be fat.
F. Don’t miss meals but exercise.
G. Instead of choosing a difficult diet, find one you can manage and stick to it every day.

“Dad，is that you？”asked the girl in wonder and amazement as she walked from behind the bushes.To Jim's shock，there stood Jim's youngest daughter，who began crying.Hugging Katherine，Jim also cried.After the police arrived，they told them about the attacker in detail.He felt it was a right decision to rush to fight with the attacker.Now in his children's eyes，Jim is a brave man and a hero without fearing any danger．

Choose from dinner at the EiffelTower’s unique restaurant against the night sky, at Les Ombres restaurant, a particular meal aboard a dining cruise down the SeineRiver or cap off the night with a Parisian cabaret show at the Moulin Rouge nightclub.
21. Which activity will you choose if you want to see cabaret show? A. Eiffel Tower Dinner B. Seine River Cruise Dinner
C. Les Ombres restaurant Dinner D. Moulin Rouge Show 22. What will the visitors do at the end of the SeineRiverdinner cruise? A.visit the Louvre B. visit theEiffelTower C. visit the Notre Dame cathedral D. visit the district of Montmartre 23. How much does the Les Ombres restaurant Dinner cost? A. $282.62 B. $313.37 C. $318.10 D. $348.84 B What can be better than a sweet treat with health benefits? As it happens, our favourite February food, chocolate, has a few shinning characteristics. It comes from the Theobroma cacao tree (food for the Gods), from a bean that grows on that tropical tree. Chocolate originated in Mexico and Central and South America, but West Africa now produces most of the world’s cocoa. Look for fair trade chocolate that meets environmental and labour standards at natural foods markets in Kitsilano and the West End, at Karmavore in New Westminster and at Nature’s Fare Markets throughout the province. Dark or semisweet chocolate is typically a vegan(素食) product. Because chocolate contains antioxidants（抗氧化剂） that prevent the oxidation （氧化）of LDL (bad) cholesterol（胆固醇）, it has gained a reputation of being beneficial for our heart health. Eaten in an appropriate amount, chocolate may lower blood pressure. Chocolate is also a source of iron –a “precious metal” when it comes to human health. As part of red blood cells, iron plays a central role in transporting oxygen to the body and carrying away the waste product carbon dioxide. Each day, we lose tiny amounts of iron in cells that are missing from skin and the inner lining of the intestine(肠壁). If our intake is not enough

I wanted to be strong, so I refused to let anyone know about my fear, even my closest friends. On the first day I was late for every class and was constantly lost. The school seemed like a puzzle that I couldn't figure out. Was this how the whole year was going to be? I didn't think I could rise to this challenge, especially carrying a huge backpack that I could hardly lift. It was so big that I could knock someone out with it!

When horses raise their noses and open their nostrils (鼻孔), their nervous system allows them to sense smells we can’t sense. This might explain why they refuse dirty water and carefully move around meadows, eating only the tastiest grasses, experts say. ◆Whale says thanks In 2011, a whale expert spotted a humpback whale trapped in a fishing net and spent an hour freeing it. Afterward, in an hour-long display of thanks, the whale swam near their boat and leaped into the air about 40 times. ◆Pandas like to be naughty Is there anything more lovely than a baby panda, except maybe a human baby? In fact, baby pandas sometimes behave like human babies. They sleep in the same positions and value their thumbs. Pandas are shy by nature for its shy behaviors such as covering its face with a paw of ducking its head when confronted by a stranger. ◆A cat honors its owner Paper towels, and a plastic cup are just a few of the gifts that Toldo, a devoted three-year-old gray-and-white cat, has placed on his former owner Iozzelli Renzo’s grave every day since the man died in September 2011. Renzo adopted Toldo from a shelter when the cat was three months old, and the two formed an inseparable bond. After Renzo passed away, Toldo followed the coffin to the cemetery, and now “stands guard” at the grave for hours at a time. 21. What can horses do to pick the most delicious grasses? A. Feel them. B. Smell them. C. Observe them. D. Taste them.
