If someone is lost in a forest( 森林 ), he needs only study the trees around him carefully to find his way. On this half of the earth, he will find that the side of the tree with the most leaves and branches(树枝 ) is the south side. Also, by checking the tops of the trees, he will find that they lean(倾斜 ) to the south too.
Another sign( 标志物) for him to know where he is going is found in the bark.( 树皮) That is brighter on the south side.The remanining(树桩 ) of a cut tree is also a finder, for its rings can give him another sign. The rings will be thinner on the south side and thicker on the north side.
One more sign: some very small plants grow at the foot of a tree and they point to the north.
【小题1】 The passage is mainly about __________.
how to find a big tree if one is lost in the forest.
How to cut down trees in the forest

| A．the direction is written on it |
| B．the rings will be thinner on the south side and thicker on the north side |
| C．the rings will be thinner on the south |
| D．its rings can send messages to you |

I began to send e-mails when I was 17. I discovered Google 5 years later. Now, I use the Internet all
the time. Internet has become so popular that 90 percent(％) of 12-to-17-year-olds in the United States
use the Internet, and about half of these children use it every day. They visit chat (聊天) rooms and
send e-mails. They go to websites to get information for their homework.
"Kids are now living in a virtual (虚拟的) world," says Greenfield, an expert at the University of
California, "As the Internet is becoming more and more important for our life, we should worry about one
question: Is the Internet good or bad for kids? "
"It's difficult to answer the question because the Internet involves (涉及) so many things," says Justine,
who is from Northwestern University. "They include online computer games, news, messages and even
e-mails to your grandmother. " So, more and more people believe that the online world can be helpful in
some ways but dangerous in others.
"Although it's not easy to tell whether it's good or bad," says Justine, "the Internet, at least, is very useful
and can be used widely by everyone in the world. "

For most people, it is enough to see their paper planes fly for a few feet. The Japanese, however, want to
make a paper plane fly for 240 miles from space. This crazy paper plane plan was brought up by the leader of
Japan Origami Plane Association (日本折纸飞机协会), Mr. Takuo. In 1999, Mr. Takuo asked Mr. Suzuki, a
designer, if he could help design a 3-metre plane for a TV program. The plane flew successfully from the top
of a mountain. Then Mr. Takuo asked Mr. Suzuki if he would help send a paper plane from space. They made
plans to drop a paper plane from the International Space Station down to the Earth. The idea is to develop a
kind of modern plane that can study the atmosphere.
An 8-inch-long paper plane has been made and treated with a chemical ( 化学药品) so that it can survive
the temperature of 200℃ as it enters the Earth's atmosphere again. Another 3-inch-long paper plane has been
tested at the temperature of up to 300℃. The paper plane will probably start its trip during a space walk. It will
continue at the same speed as the space station, but its orbit (轨道) will change slowly. Maybe it will survive
the drop, but the researchers don't know where it will land, so they have written a message in several languages,
saying, "This plane flew from the International Space Station. Please return the plane to Japan Origami Plane
Association."
If the paper plane successfully flies from space, some new design ideas can be explored. It seems to be a
crazy idea, but who can say that it isn't a creative one?
B. It can send messages from space.
C. It can land where people want it to.
D. It can study the atmosphere.
B. Because it belongs to several countries.
C. Because it may land somewhere outside Japan.
D. Because it is popular with people in different countries.
B. To provide useful ideas for making a kind of modern plane.
C. To make the life in the space station more colorful.
D. To make Japan Origami Plane Association well known in the world.
