Since 1936, many female space explorers have followed Russian astronaut Valentina Tereshkova. Let’s look at the missions(任务)of four important female astronauts to find out what astronauts do in space.

In 1983, Sally Ride became the first American women in space. Her team carried out scientific experiments in space and put two communications satellites in space. Satellites make it possible for us to communicate instantly with each other across the world through TV, radio, and telephones.

In 1984, Kathryn Sullivan became the first American women to walk in space. During her mission, she discovered important information about the sun’s energy and how it affects the climate in very hot and very cold places on Earth. She also took photographs of Earth and measured air pollution.

In 1992, Mae Jemison became the first African-American in space. During her mission, she did scientific experiments using the weightless atmosphere. In space, there is no gravity, so everything floats! Dr. Jemison’s experiments gave important information about the human body to produce better medicines and healthcare.

In 2012, Liu Yang became the first Chinese women in space. She did experiments in space medicine, which look at how astronauts can survive and stay healthy in space. The conditions in space are very hard on the body and space medicine helps astronauts work safely.

Last Child in the Woods is the first book to bring together a new and growing body of research indicating that direct exposure to nature is essential for healthy childhood development and for the physical and emotional health of children and adults.

It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming terrible. Everybody knows that the nicest men would become fierce tigers behind the wheel. It is all right to have a tiger in a cage, but to have one in the driver's seat is another matter.

Road politeness is not only good manners, but a good sense. It takes the most cool-headed (头脑冷静的) drivers great patience to give up the desire to beat back when they are forced to face rude driving. On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting. A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and becomes so necessary in modern traffic conditions. But such behavior of politeness is by no means enough. Many drivers nowadays don't even seem able to recognize politeness when they see it.

However, misplaced(用错了地方的) politeness can also be dangerous. A typical example is the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may not be able to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to.

An experienced driver told me it would help if drivers learnt to correctly join in a traffic stream without causing total blockages( 拥堵) that give rise to unpleasant feelings. Unfortunately, modern drivers can't even learn to drive, let alone(更不用说) master the roadman ship ( 公路驾车技能). Years ago, experts warned us that the fast increase of the car ownership would demand more give and take( 互谅互让) from all road users. It is high time for all of us to take this message to heart.

1.The passage mainly talks about______________________.

A. traffic jams B. good manners

C. road politeness D. modern drivers

2.Troubles on the road are often caused by__________________.

A. traffic jams

B. the behavior of the drivers

C. the great speed of modern life

D. terrible road conditions

3.According to the writer, a good driver should___________________.

A. encourage children to cross the road whenever they want to

B. beat back when forced to face rude driving

C. be able to recognize road politeness when he sees it

D. join in a traffic stream quickly however other people feel

4.It is not right for drivers to_________.

A. master the roadmanship

B. join in a traffic stream

C. give a friendly nod in answer to an act of politeness

D. encourage old ladies to cross the road whenever and wherever they want to
