ty television, there is no shortage of mindless activities to keep a child occupied. Yet, despite the competition, my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories. She wants to enter one of her stories into a writing contest, a competition she won last yes.
As a writer I know about winning contest, and about losing them. I know what it is like to work hard on a story only to receive a rejection slip from the publisher. I also know the pressures of trying to live up to a reputation created by previous victories. What if she doesn’t win the contest again？ That’s the strange thing about being a parent. So many of our own past scars and dashed hopes can surface.

Biologists today don’t expect that anyone will find a magical fountain of youth.Growing older is a natural part of the life cycle that can’t be reversed.As human beings grow older, organs such as the heart and lungs may stop functioning properly.Sight and hearing may become weak.And the human body becomes more likely to come down with serious illnesses from which it cannot recover.
Considered together, changes that bring about the decline of an organism are called aging.Because of aging, many biologists believe that there may be a maximum age limit to which even the healthiest organisms can live.For human beings, this maximum age limit is about 110 years.
Perhaps the most important thing that you can learn from your study of human biology is that you have a lot of control over the aging process in your own life.In fact, within our control are many physical and mental factors that have much to do with aging.For example, each of us, as recent research indicates, can do many things to help prevent heart and vessel disease, which causes half the death each year in the United States.We can avoid eating a lot of fatty meat.Eating too much of these types of animal fats can lead to the clogging and hardening of blood vessels.We can cut back on smoking and hopefully quit entirely.We can limit the amount of alcohol we drink and the amount of sugar we eat.We can exercise regularly and strengthen the heart and other organs.And we can remember to take time out each day for ourselves, time just relax.Exercise, recreation and relaxation all reduce stress – inner tension that is hard on all body organs.
One final thing we can do is to try to keep aware of advances made in health education.Information is often available free of charge from health clinics or schools.
1.Which of the following is the leading cause of death in the United States？
A.Heart disease.
B.Cancer
C.Alcohol
D.Smoking
2.What happens as people grow older？
A.They dream of a magic pill to help them live a happy and long life
B.They come down with serious illnesses
C.Their organs become weak and may stop working properly
D.Their blood vessels become clogged
3.In the opinion of biologists, _________.
A.the aging process can be reversed
B.the aging process can be controlled and slowed down
C.the aging process can be got rid of
D.the aging process can go beyond its limit
4.We can slow down the weakening of all our body organs by ______.
A.not eating animal fat
B.limiting drinking and smoking
C.exercise, recreation and relaxation to reduce stress
D.preventing the clogging and hardening of blood vessels
5.Besides physical and mental factors, which of the following also contributes to living a long and healthy life according tot the passage？
A.Health education
B.Traditional medicine
C.artificial organs
D.The invention of magic pills

One day I was out fishing with Spot when we heard a lot of shouting in the 38 followed by a scream and splash. I was a bit 39 so I called Spot and we both hid 40 a bush where we could see but not be 41 . After a few moments, a straw hat came drifting down the river, followed by an oar, a picnic basket and 42 oar. Then came the rowing boat itself, but it was 43 upside down ! A few seconds later my Dad and Auntie June came running 44 the river bank, both wet 45 . Spot started barking so I came out of hiding and said hello. My Dad got really angry 46 me for not trying to catch the boat as it went past. Luckily, 47 , the boat and both the oars had been caught by an overhanging tree a little further downstream, but not the hat or picnic basket. So I had to let them 48 my sandwiches. Dad and Auntie June both made me 49 not to tell Mum what had happened 50 she would be worried.

(1) Life can be tough for immigrants in America. As a Romanian bank clerk in Atlanta puts it, to find a good job “you have to be like a wolf in the forest – able to smell out the best meat.” And if you can’t find work, don’t expect the taxpayer to bail you out. Unlike in some European countries, it is extremely hard for an able-bodied immigrant to live off the state. A law passed in 1996 explicitly bars most immigrants, even those with legal status, from receiving almost any federal benefits. (2) That is one reason why America absorbs immigrants better than any other rich countries, according to a new study by the University of California. The researchers sought to measure the effect of immigration on the native-born in 20 rich countries, taking into account differences in skills between immigrants and natives, imperfect labor markets and the size of the welfare state in each country. (3) Their results offer ammunition for fans of more open borders. In 19 out of 20 countries, the authors calculated that shutting the doors entirely to foreign workers would make the native-born worse off. Never mind what it would do to the immigrants themselves, who benefit far more than anyone else from being allowed to cross borders to find work. (4) The study also suggests that most countries could handle more immigration than they currently allow. In America, a one-percentage point increase in the proportion of immigrants in the population made the native-born 0.05% better off. The opposite was true in some countries with generous or ill-designed welfare states, however. A one-point rise in immigration made the native-born slightly worse off in Austria, Belgium, Germany, Luxembourg, the Netherlands, Sweden and Switzerland. In Belgium, immigrants who lose jobs can receive almost two-thirds of their most recent wage in state benefits, which must make the hunt for a new job less urgent. (5) None of these effects was large, but the study undermines the claim that immigrants steal jobs from native or drag down their wages. Many immigrants take jobs that Americans do not want, the study finds. This “smooths” the labor market and ultimately creates more jobs for locals. Native-owned grocery stores do better business because there are immigrants to pick the fruit they sell. Indian computer scientists help American software firms expand. A previous study found that because immigrants typically earn less than locals with similar skills, they boost corporate profits, prompting companies to grow and hire more locals. 1. Increase in immigration in Austria fails to improve locals’ life mainly because of ________.
A、low wages for locals
B、imperfect labor markets
C、the design of the welfare system
D、inadequate skills of immigrants
