根据短文内容，从下框的A—F选项中选出能概括每一段主题的最佳选项。选项中有一项为多余选项。
A. Environment protection
B. Driving experience
C. Self – driving
D. Safety
E. Computing and communications
F. Wireless communications
【小题1】
Today, the Internet is in a few cars; tomorrow, broadband (宽带) will be in all of them. Any capability a personal computer has, a car will have, including two – way wireless communications for receiving e – mail, music, and movies. When you’re crossing the lonely place, the kids can watch TV if they’re bored. Every passenger will have a video feed.
【小题2】
Every car will have a self – driving system linked to GPS satellites. Radar sensors (传感器) will track nearby cars. On the freeway, they’ll slow your car when the car ahead of you slows; in town, they’ll help you park without hitting other cars. At rush hour, you’ll get the routes around traffic jams and accidents. The self – driving system in a car makes it possible for the car to drive itself, though some scientists say that’s 30 to 40 years off.
【小题3】
Motor vehicles today represent 20 to 30 percent of the world’s energy use. In the near future, a small gasoline engine and an electric motor will be brought together. Drivers will use electricity in a storage battery for short distances. Longer term, cars might burn hydrogen or use a fuel cell that converts a fuel like hydrogen and combines it with oxygen to create power. Then the waste will be pure water.
【小题4】
You’ll use the voice control: “Make it a bit cooler” or “find me country music”. Lighter, more reliable electronic controls replace mechanical controls. Fiber optics (光纤) replace electrical wires and light bulbs. Seats will be air – conditioned. The car will travel with one side higher than the other when turning, just as an airplane does now.
【小题5】
Cars will avoid some accidents by maintaining safe following distances, and by sensing sleepy or drunk drivers. Air bags will adapt for every passenger according to their size, weight, and position in case accidents happen.

Beijing—（13, July） China sent up a new data relay satellite（数据中继卫星）, Tianlian I-02, on Monday at the Xichang Satellite Launch Centre in South-western Sichuan province．The new satellite will promote the country's satellite communication network for space docking（对接）．

The satellite was launched on a Long-March-3C carrier rocket at 11:41 p．m．, sources at the centre told Xinhua News Agency．The satellite separated from the rocket 26 minutes after its launch and was then successfully delivered into a geostationary transfer orbit （地球同步转移轨道）．

Developed by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, the satellite is the country's second data relay satellite．The first, Tianlian I-01, was launched on April 25．2008．

The two satellites will form a network to improve communications between China's spacecraft and bases on Earth, according to the centre．They will also be used to help the nation's first space docking, scheduled for the second half of this year．

As planned, China will launch space module Tiangong-I, which was designed as a platform that will dock with an unmanned spaceship, Shenzhou, for the county's first space-docking mission this year．

Two more Shenzhou spaceships will dock with Tiangong-I next year, and one will be manned by two or three astronauts, according to China Manned Space Engineering Office, which was the main user of the Tianlian I series data relay satellites．

“The new satellite can cover a greater area to track and command the country’s space vehicles in low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position in outer space．Only three satellites of this kind are needed to form a global communication network, and China has two now．” Pang Zhihao, a researcher and deputy editor-in-chief of Space International, said．

The satellite could also equip astronauts with real-time communications, which will benefit the country's future manned space flights, he said．

1.What is the main purpose to send up Tianlian I-02 ?

A．To test the function of a Long-March-SC carrier rocket．

B．To carry some astronauts into space to do some research．

C．To send more information and clearer pictures to mobile phones on the earth．

D．To promote the country's satellite communication network for space docking．

2.From the passage we know??????????? ．

A．one more such satellite is needed to form a global communication network

B．the satellite was developed by China Manned Space Engineering Office

C．it was less than three years since China launched its first date relay satellite of this kind

D．the satellite could help track and command space vehicles in orbits because it's lower in position

3.Which of the following is TRUE according to the news report?

A．Shenzhou Ⅷ is a manned spaceship．

B．Tiangong-I will dock with three Shenzhou spaceships next year．

C．the satellite is of great importance to China's space exploration．

D．china’s first space docking will be done in the second half of next year．

4.The best title of the passage could be___________．

A．China Launched a New Space Shuttle

B．China's Plan for Space Exploration

C．China’s Progress in China's Space Exploration

D．New Satellite Helps China's Space Exploration

Since people first sent rockets into space in the 1950s, we have been leaving behind all sorts of things. Some of them, like the camera, were lost by astronauts while they did work outside their spaceship. But much of the space junk is made up of little pieces of things that were once bigger objects, until they struck each other and broke apart.

Some things we send into space fall back toward the earth and burn up in the atmosphere. But larger pieces sometimes survive the extreme heat and hit the ground or the ocean at great speeds. So there is always concern that something may fall from the sky and do some harm.

But space junk falling on housetops (屋顶) is not the biggest worry. Scientists are concerned about what happens when an empty rocket strikes another while orbiting (绕轨道飞行) the earth. Two big things become many smaller things. They then hit other things. The pieces get smaller and smaller until they form a cloud of junk that blocks the path of future space vehicles.

So what can be done to clean up the space around our planet? Marco Castronuovo, an Italian researcher, talks about sending a satellite into space that would get very close to some of the larger pieces of space junk. The satellite would connect a small rocket to the useless object. When the rocket explodes, it pushes the junk into a lower and slower orbit, nearer the earth. After a time, the junk burns up in the atmosphere.

Mr. Castronuovo has proposed (提议) using a number of small satellites with robotic arms. One arm would catch the space junk, and another arm would connect the rocket. He imagines that each satellite would jump from one large piece of junk to another. He thinks this method could destroy about ten large objects each year.

Scientists have been concerned about space junk for many years. Right now, the costs of the clean-up have been too great. Mr. Castronuovo says his system could be put in place for a much more reasonable amount of money.

1.Much of the space junk _____.

A．was thrown by the astronauts

B．is from broken spaceship

C．is made up of small pieces of things

D．returns to the earth piece by piece

2.Scientists are most worried that the space junk _____.

A．will stop the future space vehicles

B．will do harm to the atmosphere

C．will fall on the housetops

D．will burn up in space

3.What does Marco Castronuovo think of his system?

A．It can remove space junk completely.

B．It can save a large amount of money.

C．It can create a large amount of space.

D．It can develop robotic technology.
