A healthy life李仕才一、阅读理解Oxford English Dictionary(OED)editors recently noted that the three­letter word “run” has indeed become the single word with the most meanings with about 645 different usage cases for the verb form alone，making it the most complicated word in the English language.The various definitions of “run” featured in the OED's upcoming third edition begin with the obvious “to go with quick steps”，then continue to run on for 75 columns of type.How could three little letters be responsible for so much meaning？Context is everything.Think about it：When you run a fever，for example，those three letters have a very different meaning than when you run a bath to treat it，or when your bathwater runs over and wets your cotton bath runner，forcing you to run out to the store and buy a new one.And when you ran over a nail in the parking lot and now your car won't even run properly...God—you'd do things differently if you ran the world.When the OED's first edition came out in 1928，the longest entry belonged to another three­letter word：“set”．Even today，the print edition of the OED contains some 200 meanings，beginning with“put，lay，or stand” and continuing on for about 32 pages.So what happened? British author Simon Winchester believes “a feature of our more energetic times” made word like “set” seem more passive bycomparison.“Run” appears to have earned some major lift during the Industrial Revolution.“Machines run, clocks run, computers run—all of those meanings began in the middle of the 19th century，” Winchester says.So，ready to run through the whole list of definitions？Ah，to read all 645 meaningsyou'll have to wait for the next edition of the Oxford English Dictionary.1．Which phrase has the first meaning of “run” in the upcoming third edition of OED?A．To run a fever.B．To run out to the store.C．To run a bath.D．To run a machine.2．What does the writer intend to tell us in Paragraph 3?A．Various meanings of the word “run”．B．How to use “run” in specific cases.C．How to learn about the word “run”．D．Different ways to run the world.3．What can we learn from the text?A．“Run” is the most difficult word.B．The meaning of “set” continues on for 75 columns of type.C．“Run” had the most meanings in 1928.D．“Run” has 645 meanings for the verb form in the third edition of OED.4．What made “run” become the word with the most meanings according to Winchester?A．Oxford English Dictionary.B．The various definitions.C．Usage cases of the word “set”．D．The Industrial Revolution.【解题导语】本文是一篇说明文。

Unit 3 A healthy life李仕才一、阅读理解After a year of examining studies concerning whether homework is effective, NYC P.S. 116 elementary school decided that math worksheets and essay assignments were actually a waste of time. In February, Principal Jane Hsu sent a letter to parents stating that the Pre-K through fifth grade students would not be given any traditional homework to encourage kids to have free time for reading, playing outside, or doing activities they enjoy."The negative effects of homework have been well established," Hsu wrote in a note to parents. "They include: children’s frustration and exhaustion, lack of time for other activities and family time and, sadly for many, loss of interest in learning."Some parents, however, disagree with the policy change, believing that a lack of focus will cause children to fall behind. Homework has been part of education from the beginning, and has increased in volume in recent years.Hsu’s advice that children should read and spend time with their families ha s upset some parents to the point of considering pulling their children out of P.S. 116. This group feels that homework assignments give children a goal to work toward. Others feel so strongly about the importance of homework that they have begun giving their own homework assignments to their children.An Australian Childhood Foundation survey found that 71% of Australian parents feel they do not spend enough quality time with their children mainly because of the time spent running the household or the time spent helping with homework. Education experts in Australia are saying that parents should stop helping. Doing so will give kids more independence, will give parents more free time, and will help reduce the number of homework-induced arguments in the family.While some research suggests that homework has little academic benefit for elementary students, other research shows homework can help kids develop independence, and confidence. It can also contribute to a sense of belonging or control over their lives. When parents try to help their children with homework, the assistance can takeaway that feeling and can also drain already exhausted working parents.1.Cancelling traditional homework is aimed at __________.A. allowing students to learn on their ownB. inspiring students to spend more time with parentsC. wishing students to seek self-developmentD. motivating students to help with housework2.What can be concluded from the 1st and 2nd paragraph?A. Jane Hsu is the first principal to cancel homework.B. Jane Hsu has done thorough research on homework.C. Jane Hsu paid little attention to students’ academic records.D. Jane Hsu knows students prefer activities to their subjects.3.Why are some parents strongly against Principal Jane Hsu?A. They have no time to give their children homework.B. They don’t think the school is responsible for their kids.C. They are afraid their kids will fall behind.D. They dislike their kids doing too many activities.4.What is the author’s attitude to parents’ helping kid s with homework?A. Supportive.B. Indifferent.C. Ironic.D. Negative.【文章大意】这是一篇议论文，文章对是否应该给小学生布置家庭作业进行了论述。

选修6 Unit 3 A healthy life李仕才一、阅读理解Aging brings wrinkles, sagging bodies and frustrating forgetfulness. But getting older is not all bad for many people. Mounting evidence suggests aging may be a key to happiness. There is conflicting research on the subject, however, and experts say it may all boil down to this: Attitude is everything.Older adults tend to be more optimistic and have a more positive outlook on life than their younger and stressed opposites. The big question is why seniors are happier.A recent study suggests one reason: Older adults remember the past through happy memories. Aging can bring more cheer as people become more comfortable with themselves and their roles in society. The older adults said they were enjoying more time with their family, spending more time on hobbies and having greater financial security and did not have to work.But others are doubtful about the link between happiness and growing older."The notion that those in old age are happiest is misleading," said Richard Easterlin, a professor of economics at the University of Southern California. "It is based on comparing people of different ages who are the same in terms of income, health, family life." Easterlin added, "When you take account of the fact that older people have lower income than younger, are less healthy, and more likely to be living alone, then you will find it hard to accept that they are happier.In fact, scientists have found that as people age, their health declines and social networks disappear as their friends die, which can make the elderly less happy.Even if one does give in to age's dark side, health and happiness don't always go hand-in-hand. It's all about attitude. Research by the University of Chicago’s Yang suggests that attitude about life and happiness, is partly shaped by the era in which a person was born. It turns out that individuals who adapt the best to changes also have the highest expected levels of happiness.Despite the conflicting findings about aging and happiness, the good news is thatthere doesn’t appear to be a limit to how much happiness one can achieve in one’s life. “Most people desire happiness,” Easterlin said. “To my knowledge, no one has identified a limit to attainable happiness.”1.What does the last paragraph mainly tell us?A. The key factor to older adults’ happinessB. There is a conflict between aging and happinessC. No one can define the limit to happiness.D. The relationship between health and happiness.2.Why are some seniors happier according to some experts?A. They focus on what makes them feel good.B. They have their own circle of friends.C. They have better income after retirement.3.What can we learn from the passage?A. People of the same age have the same sense of happiness.B. Attitude may play a very important role in happiness.C. People who adapt the best to changes are more likely to be unhappy.D. Older adults who have more valuable life experience are more optimistic.4.What’s the topic discussed in the passage?A. Whether aging or attitude brings happiness.B. Why seniors adapt the best to changes in society.C. What the limit to an elder person’s happiness is.D. How older people feel compared with younger people.【文章大意】随着年龄的增加变老，人们的幸福感也是不一样的。

Unit 3 A healthy life一、阅读理解。

If you want to slow aging, you might want to eat less. This finding is good news---if you were a mouse. The researchers studied mice, not people.John Price and other researchers studied two groups of mice. One group was able to eat as much as it wanted. The researchers limited what the mice in the other group ate. Their diet had 35 percent fewer calories than the first group of mice.Price says the mice with the diet restrictions were “more energetic and suffered fewer disease.” They were not just living longer but seemed to stay younger for a longer period of time.The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes. Price explains that ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down. This gives the cells more time to repair themselves.The researchers say ribosomes use from 10 to 20 percent of the cell’s energy to make those proteins. Price wrote that “because of this, it is impractical to destroy an entire ribosome” when it starts to break down. However, “repairing individual parts of the ribosome on a regular basis enables ribosomes to continue producing high quality proteins for longer than they would otherwise. This top quality production, in turn, keeps cells and the entire body functioning well.”Price said, “ribosome is a very complex machine, like a car.” They need “maintenance to replace the parts that wear out the fastest. When tires wear out,” he explained, “you don’t throw the whole car away and buy a new one. It costs less to replace the old tires.”“Food,” he said, “isn’t just material to be burned---it’s a signal that tells our body and cells how to respond.” Price said the findings help to explain how exactly our bodies age. And this may “help us make more educated decisions about what we eat.”1.What can we know about the mice with limited calories from the study?A. They can keep healthy easilyB. They need more energy to be activeC. They can look younger than they areD. They will live a longer life like humans2.What will happen to ribosomes if there are fewer calories?A.
