　　Unit 12 B卷

　　一、阅读理解

　　A

　　EAT YOUR VEGETABLES.Wash your hands.Always say“please”and“thank you”．We are full of advice for our children，but when it comes to money，we often have little to say.As a result，our children may grow up with clean hands and good manners，but without any idea how to manage their money.

　　Here are some basics that will help guide them their entire lives ：

　　Show them the future.If your 13-year-old girl was to save $1,000，invest(投资)it at 8% and add $100 every month，by the time she’s 65，she would have $980,983 !

　　Be careful of credit(信用)．Credit cards can help you buy necessary things and build a credit history，but they must be used responsibly，which means paying off your debt in time.Explain to your children that when you buy something using a credit card，you can easily end up paying two or three times what you would have paid if you used cash.

　　Teach patience.Suppose your child wants a new bicycle that costs $150.Rather than paying the cash，give him some regular pocket money and explain that by putting aside，say，$15 each week，he will be able to buy it for himself in only ten weeks.

　　Provide incentive.Tell your children the importance of saving.“For every dollar he or she agrees to save and invest rather than spend，you agree to add another dollar to the pot，”says Cathy Pareto，expert in money planning.

　　Explain your values.Values and money are deeply intertwined(缠绕在一起)，says Eilleen Gallo，co-author of The Financially Intelligent Parent.When your child demands that you buy something，explain why you really don’t want to buy it.“You might say，‘I’d rather save that money for your education，’”advises Gallo.Every time you spend or don’t spend money，you have a chance to share your values.

　　Since the gene，called DAF-16 in worms，was found in many animals and in humans，the finding could open up new ways to affect aging，immunity(免疫)and resistance in humans，the scientists said.

　　“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits，such as immunity，”said Robin May of the University of Birmingham，who led the study.

　　Populations across the world are aging at a surprising pace，bringing potentially big challenges for health and social care systems.A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays.Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend.

　　“What we have found is that things like resistance and aging tend to go hand in hand，”May said in an interview.

　　May’s team compared longevity，stress resistance and immunity in four related species of worm.They also looked for differences in the activity of DAF-16 in each of the four species，and found that they were all quite distinct.

　　May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes，which scientists believe play a role in the aging process.

　　“The fact that subtle(微妙的)differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution，”May said.

　　5．In which section may the text appear in a newspaper?

　　A．Education.B．Science.

　　C．Entertainment.

　　　D．Culture.

　　6．What can we know from the third paragraph?

　　A．New ways have been found to affect aging.

　　B．Babies in the rich world will all live longer.

　　C．Present social care systems are poorly managed.

　　D．Aging populations are causing more challenges.

　　7．From the text we know that DAF-16 ______.

　　A．is a gene that is only found in worms

　　B．can make people live longer

　　C．has an effect on aging and immunity

　　D．has been quite familiar to scientists

　　8．What can be the best title of the passage?

　　A．Scientists Find Gene Linked to Aging

　　B．Population Aging Faster than Expected

　　C．How to Make People Live Longer

　　D．Gene Determines How Long We Live

　　二、任务型读写

　　阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。

　　After-school activities can be a wonderful thing and in a sense continue our children’s education through the school holidays.Every activity should be worthwhile and enjoyable.So what counts when we make the decision as to what activity our youngster is going to take part in?

　　Above all there should be a learning aim，like learning how to play a musical instrument，or how to dance.Any activity should be a challenge to a child，so that while conquering the challenge self-esteem and self-confidence will grow.There is nothing quite like achievements for lifting the confidence of an otherwise quiet or shy child.

　　Safety must be the number one priority of any activity.Remember nothing can be made to be 100% safe and still be fun.You should talk to an instructor and ask questions before deciding this is the course you want your child to take.Be careful of the activity itself promoting too much competition because that can make for problems and kill off enjoyment.Do not forget that this is costing you money so try to be sure that you are getting value from it.Of course discussing things with your child first is also a good idea.

　　There are two forms of parenting though.On the one hand there are those who advocate after-school activities where“everything is decided for the child”and adults make the running.On the other hand there are those who much prefer to“leave the child to his or her own devices”in so far as deciding what they want to do during their holidays.Some say that the second method encourages children to better think for themselves and that the first makes them more dependent on adults.Only you can decide which one you are and which is best for you and your child.However the main thing to remember is that your child is only young once and childhood is a precious thing soon gone.All work and no play is not a good idea.

　　Topic Effective after-school activities
