weather was like?
A tree grows well in a climate (气候) with lots of sunlight and rainfall (雨量). And little sunshine or
rainfall limits (限制) the growth of a tree. We can see the change of climate by studying the tree rings.
For example, to find out the weather of ten years ago, you can count the rings of a tree from the outside
to the inside. If the tenth ring is far from the eleventh ring, then we are sure that it was sunny and rainy
most of that year. If it is near to the eleventh ring, then the climate of that year was bad.
B. rainfall; sunshine
C. age; rainfall
D. sunshine; age

举一反三
I had hundreds of brothers and sisters. I swam about and played all day with them.
At that time I did not look like my parents. I had no legs, but I had a long tail. So I looked like a fish.
Then my tail became shorter and shorter. And now I have four legs and a very short tail (尾巴).
I know I"m going to have no tail at all soon. I"m going to be like my parents. Then I"m going to jump out
of the water. I"m going to live on the land and in the water, too. I"m going to eat a lot of insects (昆虫)-a lot
of bad insects.

( )2.I am a fish.
( )3.I have neither legs nor a tail when I was burn.

(照亮) the other side of the earth at the same time.
All day the stars are in the sky, but the light from the sun is so bright that you can not see them. When
the sun is gone, the stars are bright enough to see. Stars look very small but some are even bigger than the
sun. Big things look little when they are far away. In the sky planes look like toys. But on the ground you
can see that they are big. Stars look very small because they are far away. The sun is closer to us than the
other stars. So it looks bigger.
B.it"s always shining
C.stars are bigger than it
D.it"s bright
the sea. In fact, earthquakes may happen anywhere on the earth. They often happen near mountains.
During an earthquake, the shakings make rocks rise suddenly and even crack (断裂) open. Houses fall,
people are killed or hurt, and sometimes whole villages or cities are destroyed.
Can we do something to keep ourselves safe from earthquakes? Scientists have studied earthquakes and
made maps that show" earthquake belts (带)". In these belts, it"s possible for earthquakes to happen. In these
areas we can build strong houses to fight against earthquakes.
In the future, scientists will be able to predict exactly (精确预报) when and where an earthquake will
happen. They can also tell people what to do and how to do it.
B. in the day time
C. on land
D. at night
Where does all water come from? It comes from the clouds. The clouds can change into rain. Some of the
rain goes down the ground. Some of the rain water goes down the mountains into streams (小溪). The streams
come together to make rivers and lakes.
Water can change itself. When water gets very cold, it becomes ice. When water gets very hot, it becomes
steam (小蒸气).
A. Only animals
B. Only plants
C. Only people
D. All living things
planet. The first man-made satellite went into the orbit in 1957. By 1968 there were over three hundred
satellites in the orbit. Some satellites send back weather pictures. Others send out radio waves. Some
satellites are what we call "junk". In 1963, the United States put millions of small pieces of wire into orbit.
They were used to carry radio waves. Many of these wires may still be there. Some space junk was not
put in the orbit. For example, one piece of space junk is a glove lost by an astronaut!
Space is very big. Does it matter if there is junk in the orbit? Many scientists think so. They say we
must pay much attention to how we use this new resource. They think anything man puts into space
should be made to come back to earth when its work is done. They say it"s dangerous to have space junk,
because it"s possible for spacecraft to collide with the junk.
B.1963
C.1968
D.1975
