第三部分：阅读理解(共15小题；每小题2分；满分30分) 请阅读下列短文,从短文后各题所给的A、B、C、D 四个选项中,选出最佳选项,并在答题 卡上将该项涂黑。 A There’s nothing like a good night’s sleep — but what does that really mean? It turns out that the answer depends not only on your age, but also on your lifestyle. Some people are productive and happy with fewer hours of sleep, while others need more. Still, experts can determine guidelines that work for most people. The National Sleep Foundation researched the topic and gave new recommendations this week. The foundation acknowledges that sleep needs will vary — lifestyle and stress should be taken into consideration — but their recommendations offer a general guideline. For example, teenagers (14 —17 years old) need 8—10 hours’ sleep every day. To create the recommendations, some sleep and medical experts reviewed 312 articles from journals published during the last decade. This is the first time that any professional organization has developed age-specific recommended sleep durations based on a systematic review of the world scientific literature. A lack of sleep can be linked to weight gain, because that causes an increase
in appetite, according to the foundation. It can also have serious consequences on the brain. People who do not get enough sleep are at increased risk for depression, and can endanger others. Those that become sleepy while driving, for example, risk both their lives and the lives of those around them. Researchers also have found in the past that too much sleep can have negative e ffects. Low socioeconomic status and depression reportedly are significantly associated with longer sleep. However, experts nowadays find that research on oversleeping is still unconvincing and needs more attention. Currently, there is no strong evidence that sleeping too much has health consequences. There is, however, laboratory evidence that short sleep durations of four to five hours have negative consequences. We need similar laboratory studies to determine whether long sleep durations result in physiological changes that could lead to disease before we make any recommendations against sleep extension. 56. Which is TRUE about sleeping time? A. Experts’ guideline for sleeping time applies to all the people. B. The time you need for sleep is related to your state of mind. C. The less you sleep, the more productive you are. D. The more you sleep, the more energetic you are. 57. How did the National Sleeping Foundation do the research? A. By interviewing different people. experts. C. By reading lots of articles. experiments. 58. The research shows that people without enough sleep will _______. A. lose some weight C. dream during their sleep A. more research on oversleeping is needed B. researchers now agree with those in the past C. too much sleep may result in social changes D. research on oversleeping is quite convincing B With a large part of the world's population living close to the oceans, rising sea levels bring the potential for destructive (破坏性的)results. But scientists are still unable to make predictions exact enough for people to plan to handle the loss of land and the threat to coastal communities expected over this century. “We know sea level is going to rise, but how much, and how fast, and where, we really still don’t know," said Josh Willis, a climate scientist. The ocean isn't like water in a bathtub. It doesn’t rise all the same as more water pours in. As global warming raises sea levels, some places are expected to B. drive faster than usual D. eat more food D. By doing systematic B. By consulting other
59. From Paragraph 4, we can learn that _______.
see higher-than-average increases, and a few places, may even see decreases. It’s reported that over the course of this century, sea levels will rise between 8 inches and 6.6 feet around the planet. Scientists know this increase will be driven by the expansion of water as it warms—warmer water takes up more space—and the melting of ice. But the effects of warming water and melting ice on sea-level rise are expected to vary from area to area. And the melting of ice of the Antarctic and Greenland presents the largest uncertainty for the future, but air, land and water also play roles in changes to sea level. For example, sea level near the ice getting melt actually decreases, because the ground under the melting ice rises as the heavy ice disappears. Climate change is expected to change ocean currents and the winds that help drive ocean currents. These changes will affect the distribution of heat within the oceans, and, as a result, affect changes in sea level. Nowadays, scientists use two types of models to make predictions about the future of sea levels, but the two don’t agree. If scientists can't accurately predict sea-level increase for the coming years, the least we can do is measure what happening today with the help of the satellite, Jason-2, but it’s reaching the end of its operational life. 60. The first paragraph implies that_______ . A. coastal cities are easily affected by the rising sea levels B. people living in coastal communities have to move C. scientists have ways to handle the rising sea levels D. the rising sea levels mainly happens near the coast 61. What does the writer mean by saying "The ocean isn’t like water in a bathtub" in the third paragraph? A. There is too much water for us to control. B. The ocean can be easily controlled. C. The ocean isn’t equal to a bathtub in size. D. The rising sea level is hard to tell. 62. According to the text, which of the following shows the right cause and effect? ①climate change; ④changes in sea level; A. ①→②→③→④→⑤ C. ①→③→②→⑤→④ ②ocean currents; ③the winds; ⑤the distribution of heat B. ③→④→⑤→②→① D. ①→⑤→③→②→④
63. What problems will scientists meet with in predicting future climate changes? A. It's too difficult to measure what's happening. B. There will probably be no satellites to help the scientists. C. Types of models for prediction are difficult to set up. D. There aren’t enough scientists studying the changes of sea levels .

Beluga & Friends Interactive Program D. Journey with Gentle Giants Immersion Program D This is my world now; it's all I have left. You see, I'm old. And, I'm not as healthy as I used to be. I'm not necessarily happy with it, but I accept it. Occasionally, a member of my family will stop in to see me. He or she will bring me some flowers or a little present, maybe a set of slippers—I've got eight pairs. And then they will return to the outside world and I'll be alone again. Oh, there are other people here in the nursing home. Residents, we're called. The majority are about my age. I'm 84. Many are in whe elchairs. The lucky ones are passing through—a broken hip, a diseased heart, something has brought them here for rehabilitation(康复). When they're well they'll be going home. The help here is basically pretty good, although there's a large turnover of staff. Just when I get comfortable with someone he or she moves on to another job. I understand that. This is not the best job to have. I don't much like some of the physical things that happen to us. I don't care much for a diaper(尿布). I seem to have lost the control acquired so diligently as a child. The difference is that I'm aware and embarrassed, but I can't do anything about it. I've had three children, and I know it isn't pleasant to clean another's diaper. My husband used to wear a gas mask when he changed the kids. I wish I had one now. Why do you think the staff insists on talking baby talk when speaking to me? I understand English. I have a degree in music and am a certified teacher. Now I hear a lot of words that end in “y”. There is little need for anyone to position their face directly in front of mine and raise their voice with those “y” words. Sometimes it takes longer for a meaning to sink in; sometimes my mind wanders when I am bored. But there's no need to shout. I'd love to go out for a meal or travel again. I'd love to go to my own church, sing with my own choir. I'd love to visit my friends. Most of them are gone now or else they are in different “homes” of their children's choosing. I'd love to play
a good game of bridge, but no one here seems to concentrate very well. My children put me here for my own good. They said they would be able to visit me frequently. But they have their own lives to lead. That sounds normal. I don't want to be a burden. They know that. But I would like to see them more. One of them is here in town. He visits as much as he can. Something else I've learned to accept is loss of privacy. Quite often I'll close my door when my roommate—imagine having a roommate at my age—is in the TV room. I do appreciate some time to myself and believe that I have earned at least that courtesy(礼貌). As I sit thinking or writing, one of the aides invariably opens the door unannounced and walks in as if I'm not there. Sometimes she even opens my drawers and begins searching around. Am I invisible? Have I lost my right to respect and dignity? I am still a human being. I would like to be treated as one. Back to my semiprivate room for a little semi-privacy or a nap. I do need my beauty rest; company may come today. What is today, again? The afternoon drags into early evening. This used to be my favorite time of the day. Things would wind down. I would kick off my shoes. Put my feet up on the coffee table. Pop open a bottle of Chablis and enjoy the fruits of my day's labor with my husband. He's gone. So is my health. This is my world. 67. Which of the following statements can be inferred from the passage? A. The staff used baby talk with her because they assumed her mind had aged as her body had. B. Nursing home workers sometimes stole items from her drawers. C. Her children did not often visit because they felt guilty for having put her in the nursing home. D. The staff at the nursing home mistreated the elderly people. 68. The author concluded her essay with a tone of ________. A. dignity D. confusion 69. How will the author's son most probably feel after he reads this essay? A. Sympathetic. B. Relieved. C. Angry. B. The Elderly D. Regretful. : D. A Forgotten The Place 70. The best title for the passage would be ________. A. The Disadvantages of Growing Old Generation C. If Only I could Be Getting Better That Changed My Life 第四部分：任务型阅读(共10 小题；每小题1 分， 满分10 分) 请阅读下面短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。 注意：请将答案写在答题卡上相应题号的横线上。每个空格只填一个单词。 Few people need to be told not to overspend on credit or debit cards or to curb i mpulse shopping. You know you shouldn’t, even if you always do. What you need are solutions. Whatever your problems with money, you can change—but it’s going
to take work. After all, you’re trying to break lifelong patterns. Start with these strategies. Strategy 1 A lot of people set themselves up for failure because they have a mindset of either indulgence (放纵) or deprivation (克制). If you try to deprive yourself of too much, where you spend almost nothing, then you end up giving up, and you indulge, and then you overspend. So if you have an unrealistic plan, you’re probably going to lose control. Good habits happen when planned; bad habits happen on their own. Strategy 2 Changing your mindset is effective in solving the problem. Take Smith-Acuna for example. She says she had a couple in therapy who constantly quarreled about what she feels has become a monetary cliché. They would always argue about how much money they were spending at Starbucks. The wife loved capping off each workday with a drink. Ultimately, the wife ended up quitting her Starbucks habit. Instead of replacing her drink with nothing, she got something else, something free, in return. Strategy 3 It’s a good start if you switch from paying for merchandise and services with a debit or credit card to paying with cash. It’s easy when you’re using plastic to mindlessly swipe and fall into a pattern of not thinking or noticing how much you’re actually spending. You can divide up your money and put it into envelopes, marking down on the envelopes what each pile of money is for. That can make it easier to see where your money is going. Strategy 4 Get a receipt for every purchase. Breaking up your expenses into categories like food, clothing, housing, medical care and so on, but also labeling each expense as a need or a want. Be realistic as to what is really necessary. A need is something where you would die or go to jail if you didn’t spend the money or ruin your credit. At the end of the month, total up all the categories. Do this, and you’ll be more educated about how much money you actually have, and how much you have left over for fun stuff. Strategy 5 There is probably a reason you developed bad habits, which are often adopted on the road easier traveled. So if you’re suddenly balancing your bank account every day, or you’re regularly putting money into an emergency fund, plan to give yourself some sort of prize for the past two weeks. You’ve been saving money or spending it more wisely, so you can probably afford it.
More often than not, (71) ▲ that we shouldn’t overspend, we still tend to do so.
? ? ? ? ? ?
It’s time we (72) ▲ pains to change our bad shopping habits. We can use the following 5 strategies intended to help us solve problems with money. Having a mindset of either indulgence or deprivation means going to extremes, which often leads to (73) ▲. In case you lose control, it’s a good habit to make (74) ▲ plans. Chang your mindset. Without spending too much money at Starbucks, the wife successfully got (75) ▲ of her bad habit by having something else in return.

The number of these left-behind children living with their grandpar ents or great-grandparents is currently estimated at 60 million nationwide. These children often face severe psychological and emotional problems as well as challenges to their personal safety and well-being. According to a report published by the All-China Women's Federation (CWF), the number of left-behind children in rural areas stands at 61.026 million, accounting for 37.7 percent of rural children and 21.9 percent of all children nationwide. A generation of left-behind children is emerging in China. As a special social group, they are vulnerable to physical and emotional hurt, with their personal safety often compromised because they are far away from their parents. In recent years, we have seen an increasing number of left-behind children suffering from death by drowning, poisoning, traffic accidents or fire incidents. 【写作内容】1. 用约 30 单词写出上文概要； 2. 简述留守儿童面临的问题（安全、教育、身心健康等） ；

They suffer a lot physically and emotionally. (31 words) The left-behind children are faced with many problems. To begin with, without parents’ protection, they are likely to become the targets of bullying and abuse. Second, not only do they have to take on the burden of farming, they also struggle to keep up with their studies. Some are slowly becoming "lagging-behind" children and some even end up abandoning school. Moreover, many children feel stressed and lonely for lack of parental care and love. In the rush for economic opportunity and growth, these left-behind children have become victims and this social problem needs a solution. The government should establish a protection network involving schools, families and communities. Moreover, migrant workers should take their responsibility as parents by accompanying their children to ensure their sound development.
