A home computer not only helps children master the old ways of learning, but also opens up possibilities that simply aren’t available in traditional education. Some software, for example, allows kids to make decisions and see the results in different situations. The World Wide Web encourages young minds to move easily from link to link, topic to topic. The best software draws children into learning by making them curious — what if I click on this picture, drag this over here, visit that website?

Knowing how to use a computer also encourages a child’s confidence. Kids figure out quickly that computers are powerful, and mastering the machine makes them feel grown-up. In turn, feeling confident on a computer often translates to academic (学术的) confidence. Researchers have found that attitudes toward writing, for example, improve when students write on a computer.

Perhaps most importantly, computers can enrich family life. Forget the idea that computer kids are separated. Children like to use the computer with adults and other kids, asking questions and comparing results. “The Internet is a unique opportunity to bring resources home,” notes Susan Haugland, PhD, Cape Girardeau, Mo., author of Computers and Young Children: A World of Discovery.

Although the benefits of computers are real, they have disadvantages, too. Kids can lose their way, wasting hours on mindless software or violent games. Just as parents have always helped children make good choices about everything from friends to food, books to TV, now we must make sure they get the best out of computers.

1.The passage is mainly talking about _____.

A. the disadvantages of children’s using computers

B. the advantages of children’s using computers

C. the development of computers

D. the fact using computers makes children lose their way

2.Which of the following is NOT an advantage of a home computer?

A. It provides new ways of learning.

B. It encourages children’s confidence.

C. It can enrich family life.

D. Kids can play violent games on it.

3.What effects do computers have on family life?

A. They reduce the connection between family members.

B. They destroy the relationship between parents and kids.

C. They provide more opportunities of communication.

D. They make all the family members study together.

4.According to the last paragraph, we can learn that we should _____.

A. let children use computers freely

B. forbid children to use computers in their spare time

C. permit children to use any software they like

D. help children make good use of the computers

Parents Model Healthy Eating

It should come as no surprise that the more stressed parents are not work, the greater the burden on their family is. 1.After all, the more time parents spend working, the less time and energy they have to plan and prepare healthful meals.

For years, most studies have focused on the role of working mothers while fathers were ignored. They didn’t look at the family as a whole, 2., adds a new wrinkle to the relationship between work stress and family nutrition.

Moms’ work related stress is still a central factor in how well families eat because they typically do most of the food shopping and cooking.3.The study found that when mom or dad experience high levels of work related stress, their families are eating one-and-a-half fewer family meals per week, and the parents themselves report eating fewer fruits and vegetables, more fast food, and are less likely to eat breakfast regularly.

It’s worth noting that the study looked mainly at low income families who belonged to ethnic or minority groups. 4. But the implications are wide ranging.

5.Teaching kids, especially teenagers, to help with grocery shopping and to cook actual meals, instead of just putting a frozen pizza in the microwave, could be an important piece of the puzzle in helping families improves their eating habits.

A. When it comes to family nutrition, the entire family plays a role even kids.

B. so the findings don’t necessarily apply directly to other types of families

C. But dad’s work related stress has a large impact, too.

D. Yet, the kids’ stress may influence the families’ nutrition, too

E. and at the role of fathers in particular

F. It’s also probably not a surprise that his can negatively affect a family’s nutrition

G. It is parents who give their kids a good model to develop a good eating habit.

Our planet is home to about seven billion people. Since the 1990s, population experts have predicted the number would grow to nine billion before it begins to slow down and possibly decrease.

But a new report predicts the world’s population is likely to increase to almost 11 billion by 2100. Based on the most modem statistical tools, the new report makes use of government records and considers expert predictions, including death rates, birthrates and international migration, or people moving across borders. The report says during the rest of this century, Africa’s population will grow from about 3.5 billion to 5.1 billion over the next 85 years.

John is director of the United Nations Population Division. He says that in the past, researchers thought population growth in Africa would be similar to that of other areas. They expected slower growth rates as birth control use became more widespread. But he says those ideas were wrong.

“The level of contraception use has continued to increase but slowly — more slowly than expected, and birthrate therefore has been falling less rapidly than expected, and the population therefore continues to grow somewhat more rapidly than we expected.

The new findings are based on a joint research project of the United Nations and the University of Washington,

The researchers believe the population of Asia will reach five billion by 2050. That is up from the current 4.4 billion. And then begin decline. The researchers also believe that North America, Europe, Latin America and the Caribbean area will have a total population of below one billion.

John says the pressure of feeding the rising population is likely to be less than that might be expected.

“The relatively good news is that the world has been winning the race between population growth and food production. If you look back historically over the last 50 years, certainly for the world as a whole and for many, most individual countries and regions, the increase in food production has outpaced the increase of population.”

1.Which area will experience the largest increase in population at the end of the century?

A. Asia. B. Africa.

C. Europe. D. North America.

2.“Contraception use” in the fourth paragraph refers to ________.

A. a method of expert predictions

B. a way of avoiding growth in population

C. a joint research into the rising population

D. a potential technology for food production

3.Why is the pressure of feeding the rising population less than expected according to John?

A. Expert predictions are not exactly like what the facts happen.

B. Birthrates have always been falling less rapidly than we expected.

C. The population grows less rapidly than population experts expected.

D. The increase in food production has outpaced the increase of population,

4.What can be inferred from the passage?

A. The world’s population will increase constantly.

B. The population of Asia will rise by 5 billion by 2050.

C. John is optimistic about feeding the rising population,

D. Population growth in Africa was much slower than expected.
