This passage is written to .A．gift givers B．foreign visitors C．Disney fans D．animal loversBDrawing the lineIn 2006, I decided to stop shopping for a year. I always used to go into stores and just buy thingswithout thinking about it and it bothered me.In 2012, I noticed I had replaced this addiction with another-buying useless things on the internet.I would look at pictures of nice things on websites, and before I knew it, I would have wasted an hourlooking at them and sometimes buying things I didn’t need. So I stopped shopping again. This time, instead of buying the things I wanted, I drew them on the paper.It was exciting to realize that there is nothing wrong with liking beautiful things. In fact, it’s hard not to like beautiful things in a world that’s filled with them, in a world that’s good at showing you the kind of beautiful thing you most want, and in a world where people try to make you want beautiful things. Why did I feel bad about wanting to shop?Drawing the things I want doesn’t make me want to buy things that I don’t need any longer. But you don’t have to draw the things you want to stop you from buying them. It also works to take some time to stop and think about why you want that shiny new thing.24．The author stopped shopping again because______________.A．she wasted too much time comparing goods B．she was bothered that she was taking too muchC．she had become addicted to buying things online D．she spent too much time looking in stores 25．What can we learn from paragraph 3?A．It’s natural to love things.B．She should feel guilty of loving beautiful things.C．If more people stopped shopping, less will be produced.D．Producers are taking advantage of her desire for beautiful things.26．In the last paragraph, the author suggests we should______________.A．not feel guilty about shoppingB．reflect on what causes our desire to buy somethingC．talk about the things we want to buyD．think of the harmful effects on the environment before we buy anything27．What is the main purpose of the article?A．To share her experience and understanding of shopping addiction.B．To explain the damage shopping does to the planet.C．To show how much on line shopping addiction costs.D．To explain why people should feel guilty about wanting to shop.CWe’ve all known people who run out of steam before they reach life’s halfway mark. I’m not talking about those who fail to get to the top. We can’t all get there. I’m talking about people who have stopped learning on growing because they have adopted the fixed attitudes and opinions that all toooften come with passing years.Most of us, in fact, progressively narrow the variety of our lives. We succeed in our field of specialization and then become trapped in it. Nothing surprises us. We lose our sense of wonder. But, if we are willing to learn, the opportunities are everywhere.The things we learn in maturity seldom involve information and skills. We learn to bear with the things we can’t change. We learn to avoid self-pity. We learn that however much we try to please, some people are never going to love us — an idea that troubles at first but is eventually relaxing. With high motivation and enthusiasm, we can keep on learning. Then we will know how important it is to have meaning in our life.However, we can achieve meaning only if we have made a commitment to something larger than our own little egos(自我), to our loved ones, to fellow humans, to work, or to some moral concept. You may think this is just for those heroes. In fact, doing any ordinary job as well as one can is in itself an admirable commitment. People who work toward such excellence — whether they are driving a truck，or running a store-—make the world better just by being the kind of people they are. They’ve learned life’s most valuable lesson.28．What does “run out of steam” probably mean?A．End one’s struggle for liberty. B．Waste one’s energy taking risks.C．Lose the interest to continue learning. D．Miss the opportunity to succeed.29．Which one is true according to Paragraph 2?A．Those who dare to try often get themselves trapped.B．Opportunity favors those with a curious mind.C．Those who tend to think back can hardly go ahead.D．Opportunity waits for those with a cautious mind.30．What can we infer form Paragraph 3?A．An adult mainly learns information and skills. B．A wise man can live without self-pity.C．A man should try to satisfy people around him. D．An adult should learn how to deal with life.31．What is the author’s purpose in writing the passage?A．To provide guidance on leading a meaningful adult life.B．To stress the need of shouldering responsibilities at work.C．To state the importance of generating motivation for learning.D．To suggest a way of pursuing excellence in our lifelong career.DResearchers continue to show the power behind our sense of smell. Recent studies have found, among other things, that the smell of foods like pizza can cause uncontrollable anger in drivers onroads.Smell, which dictates(决定) the unbelievable complexity of food tastes, has always been the least understood of our senses. Our noses are able to detect up to 10,000 distinct smells. Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004 for their ground-breaking research on the nature of this extraordinary sense. These two scientists were the first to describe the family of 1,000 olfactory (嗅觉) genes and to explain how our olfactory system works.According to one study in the research review, smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users. They are then more likely to speed and experience uncontrollable anger on roads. The most reasonable explanation is that these can all make drivers feel hungry, and therefore desperate to satisfy their appetites.In contrast, the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers’ impatience. Similarly, the smells of lemon and coffee appeared to promote clear thinking and mental focus.However, the way genes regulate smell differs from person to person. A study by researchers in Israel has identified at least 50 olfactory genes which are switched on in some people and not in others.They believe this may explain why some of us love some smells and tastes while others hate them.The Israel researchers say their study shows that nearly every human being shows a different pattern of active and inactive smell-detecting receptors.32．What did Richard Axel and Linda Buck find out?A．The type of food smells. B．The logical part of human brain.C．The nature of human olfactory system. D．The relationship between food and feelings. 33．Which of the following can help people concentrate?A．Bread. B．Fast food. C．Pizza. D．Coffee.34．What do we know from the last paragraph?A．Different people are sensitive to different smells.B．Every person has a different pattern of genes.C．Some people can recognize up to 50 smells.D．There are still some olfactory genes to be found out.35．What is the passage mainly about?A．Logic and behavior. B．Smell and its influence.C．Sense ability and food tastes. D．Olfactory genes and its system.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。
