Have you ever wondered?
1. Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet (喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction.
2. What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures (建筑物) float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string (细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’ gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space.

C．come out	D．grow quickly

【小题3】It can be inferred that without gravity __________.

A．buildings and other structures would float away

B．trees and buildings would not so easily fly off

A．It takes seven hours to travel from London to New York.

B．The earth is moving at a high speed

C．Everything on the earth will float away if there’s no gravity.

1.      Why do airplanes take longer to fly west than east?

It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon (大气现象) known as the jet stream (气流). The jet stream is a very high altitude (=" above" sea level) wind which always blows from the west to the east across the Atlantic. So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite.

2.      What would happen if the gravity on Earth was suddenly turned off?

Supposing we could magically turn off gravity. Would buildings and other structures（建筑物）float away? What happened would depend on (依靠) how strongly the things were attached (吸附) to the earth. The earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Turning off’ gravity would be like letting go of the string. Things not attached to the earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling (=" top" surface of a room). Most things outside would fly off into space.

It was reported today that in China, 56% of people who write blogs(博客) do so as a personal diary and 83% use their blogs for sending messages to friends. It was also found that there is a strong East- West difference. In places like the US, blogs that offer information on news attract more readers but in China, blogs are more likely to be about sharing personal feelings.
It seems that bloggers can be divided into three types: IT bloggers, bloggers who record their ordinary feelings and media（媒体） bloggers.
When blogging first started, the IT people had the technological advantage and they took the chance to put their thoughts on the web. Some of these IT people now have had over a million people read their blogs.
The next wave of bloggers did not have any training as writers or in IT and wrote about normal daily life. Media bloggers, however, are trained writers, such as journalists and editors. When the many media bloggers showed up, the everyday bloggers lost most of their readers. Media bloggers have the advantage of knowing how to communicate well through the written words.
However, the normal bloggers are still out there and increasing in number. It seems that blogging is the new way to express your feelings. People feel like the world is listening to, or rather reading, their problems, even if they are not.
【小题1】 From the passage we know that________.

A．56% of the Chinese write blogs

B．people in US like to read blogs for news

C．the Chinese never share feelings with each other through blogs

D．the way that Chinese use blogs is not different from the West

【小题2】 ________wrote more blogs at the very beginning .

A．IT bloggers	B．Media bloggers
C．Normal bloggers	D．US bloggers

【小题3】Which of the following is true according to the passage?

A．There will be more and more normal bloggers.

B．Only bloggers express their feelings through the Internet.

C．All people in the world are listening to the bloggers’ voice.

D．Media bloggers didn’t have the advantage of knowing how to communicate well.

【小题4】The underlined expression in the passage can be best replaced by “________”.

A．increased.	B．appeared .
C．arrived.	D．grew.
