任务型阅读

    The lifestyle of families has changed because of science and industry(工业).

    More Americans used to live on farms, nearly each family had many children. In a farm family, parents and their children often lived with grandparents. Uncles and aunties often lived nearby, too. But when industry became more important than agriculture(农业)in American life, families became smaller, industry needs lots of workers. They must be ready and able to move off the land and move again whenever necessary. It isn't easier for large families to move from place to place as small families can. Today, more and more small families have appeared, smaller families may have no children and they may have only a man and a woman because keeping children is really hard work. It takes parents not only money and time, but also much more energy and makes young couples(夫妇)busy working, studying and enjoying their lives all day. They are probably not important in keeping children.

    That's why the increasing of population in most developed countries are becoming more and more slowly, In China today, each family has only one healthy child because of one-child policy.

    In this way, the country can develop farther than before and young children can have more opportunities to get education and to find suitable jobs.

(1)、Did each family only have one child in the past?

(2)、Why have the families become smaller and smaller?

(3)、What may a smaller family have?

 

(4)、Who did parents and their children use to  live with?

(5)、which countries' population increases faster, developed countries or developing countries?

Save the world's trees

    "When it comes tothe Earth, there is no time to waste." says the Earth Day Network. And that isright. Protecting our environment is very important, and World Earth Day wascreated in 1970 to ask more people to protect our environment. On April 22, peoplearound the world celebrate Earth Day.

Every year thereis a special topic, and this year it is "Trees for the Earth", so Earth Daythis year will be all about planting trees. They are planning to plant 7.8billion trees within the next five years.

That's a biggoal, and you might wonder why trees are so important. Because they can take incarbon dioxide (CO2) and protect the air quality(质量). CO2 isa chemical in our atmosphere, but humans make too much of it. Each person makesabout 2.3 tons a year, which is bad for the environment.

Well guess what!Planting new trees is important because people cut down a huge number of trees.Last year, there were 3 trillion trees in the world, about 139 billion inChina. But according to China Daily, the world's total number has been almostcut in half since human civilization(文明) began. That's because 15billion trees are cut down every year.

So we need toplant more to make up for(弥补)the ones we lost. One treecan take in 21. 8 kilograms of CO2 per year. And it's still one ofthe cheapest and best ways to get rid of CO2.

    But don't forget that we can also help the environment by cutting down on how much energy(能源) or water we useevery day. Every little thing helps.

How do blind people get around safely? Some people use special guide dogs. A well-trained dog knows how to help its owner cross busy streets and get from place to place. Some people use long white canes(手杖)to help them get around. 

Guide dogs and canes are helpful, but there must be a better way for blind people to get around. A scientist in England thought so. His name is Waters and he studies bats(蝙蝠). He knows that bats are able to fly in the dark. Besides, he knows that bats go by using sound to "see". Dr. Waters wondered if people could do something similar. 

Bats make sounds as they fly. These sounds travel in waves(波)in the air. When the waves hit an object such as a tree or house, they bounce back(反射回来). The waves travel back to the bat's ears. A bat learns the location and shape of objects around it. 

Dr. Waters talked to other scientists, including Withington from America and Hoyle from Germany. They worked together and invented a new kind of cane. They called it a "bat cane" because their idea started with bats. The new cane has a computer in the handle(手柄).  ▲  The sound waves hit objects and echoes(回声)back. This causes the handle to make sounds, which humans can hear. 

With a little training, a person using the cane can easily tell where objects are and can "see" with sound!
