     Growing kids need sleep, as do people of all ages. Indeed, research shows that health and safety both
suffer when we try to get by with too little shuteye. So it's fortunate that our bodies do such a good job
of waming us when it's time to hit the sack.
     Like humans, other animals also take time out to rest. You've probably seen a lion dozing at the zoo,
or maybe watched our dog snooze away lying in its bed. In fact, sleep is a necessity for every animal that's
ever been studied.
     How long animals sleep, though, varies widely. Elephants and giraffes sleep only about 2 to 4 hours a
day, while bats may nod off for up to 20 hours. Ducks sleep together, and the birds on the edge of the group
sleep with the outside eye open and half of their brain awake-probably to keep watch while the other half of
their brain snoozes. Some birds may even sleep while flying. The fact that all animals make time for sleeping,
even under very dangerous situations, suggests that sleep is very important. And indeed, some facts suggest
that sleep is important for leaming and forming permanent memories.
     But sleep may also be primarily a way for animals to save energy and stay out of harm. This may help
explain why meat-eating creatures sleep more than herbivores, which are animals that live only on plants.
Herbivores, like cows and zebras, need to spend more time searching for and grazing on food than meat eaters
do, such as lions and other big cats. So a big cat might be better off sleeping for a while after it eats, rather
than prowling around and risking injury.
     But that's just a guess. Scientists need to study other animals as well before they can fully understand the
benefits (好處) of sleep and know which benefits are most important for a particular species (物種).
     One thing is certain: enough sleep is important to health and learning. So give in when a strong wish to
sleep hits, and catch plenty of ZZZs.
1. The underlined phrase "to hit the sack" means ____.
A. to eat something
B. to drink something
C. to get up
D. to go to sleep
2. From the last paragraph, we can infer ____.
A. enough sleep may improve your learning in class
B. if you want to sleep in class, fall asleep immediately
C. you are easy to give in if you have plenty of sleep
D. if you have a strong wish to sleep, you are perhaps ill
3. The main idea of the passage is about ____. 
A. all people need sleep
B. how animals sleep in the open air
C. why animals need sleep
D. when animals feel sleepy

　　Do you know something about tree rings(年輪)? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?

　　A tree will grow well in a climate(氣候)with lots of sunshine and rainfall．And little sunshine or rainfall will limit(限制)the growth of climate by studying the tree rings．For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside．If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year．If it is near to the eleventh ring, then the climate that year was bad．

　　Tree rings are important not only for studying the history of weather but also for studying the history of man．Many centuries ago there lived a lot of people at a place in New Mexico．But now you can find only sand there－no trees and no people．What happened?

　　We sometimes say the lion is “the king of the jungle(叢林)” because it is stronger and more dangerous than the other animals. It can run faster than most other animals and it can hunt(捕獵) the best. The lion is the highest animal in the land food chain. In the sea, the shark is at the top of the food chain. It can swim faster than most other sea animals. It can also use its big teeth to catch other sea animals and eat them.

　　What is at the top of the world's food chain? People are! We are not the biggest or fastest, but we are the cleverest. We could not run faster than most animals, so we invented cars and now we can move the fastest. We could not fight better than a lion, so we invented guns. Now we can hunt the best.

　　People's inventions are clever, but they can be dangerous, too. For example, many years ago in Inner Mongolia, people used guns to kill a lot of wild wolves. The wild wolves usually eat wild rabbits. But in recent(近來的) years, the number of wild rabbits is becoming bigger and bigger because the number of wild wolves is getting smaller and smaller. The wild rabbits competed(競爭) for the grass with the sheep and cows. Much of the grassland became desert because it was seriously destroyed(毀壞) by the rabbits.

　　Remember that we are a part of the food chain, so we are in danger, too! If we protect animals, we are protecting ourselves.

1．How many kinds of food chains are mentioned in this passage?

[　　]

A．Two.
B．Three.
C．Four.
D．None.

2．Why are people at the top of the world's food chain?

[　　]

A．Because they can use guns.

B．Because they are the biggest.

C．Because they are the cleverest.

D．Because they can drive cars.

3．Which order of the pictures best describes the third paragraph?

[　　]

A．b, d, a, c, e
B．b, d, f, c, e
C．b, f, a, e, c
D．b, e, d, c, a

4．In what way do we say people's inventions can be sometimes dangerous?

[　　]

A．They can kill a lot of wild wolves.

B．They can destroy the food chain.

C．They can destroy the grassland.

D．They can make wild rabbits grow bigger and bigger.

5．What is the best title(標(biāo)題) of the passage?

[　　]

A．People's inventions
B．Lions and sharks
C．Food chain
D．Desert

任務(wù)型閱讀理解
仔細(xì)閱讀下面的短文并按要求完成后面的小題。
The giant panda is one of the most popular animals in the world. A giant panda can grow up to 1.5 meters long and weigh up to 160kg. People think the giant panda is very lovely. ①So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people about animals that they are in danger and raises money to save them.
The giant panda only lives in the wild in China. In the early 1980s, were only 1,000 left in the wild. The main reason why pandas are endangered is that the area where pandas can live has become smaller.
The WWF works to help giant pandas in the wild in many ways. One of the ways that helps them is to increase the size of panda reserves(自然保護(hù)區(qū)). Some reserves need to be joined together by planting bamboo between them to make “corridors”. These are paths that lead from one reserve to another. No one may harm the pandas in these areas. The corridors let pandas move from one habitat(棲息地) to another to look for food. ②People are working very hard to make sure the giant panda does not die out.
【小題1】How long and heavy can a giant panda grow to be?
【小題2】將文中劃線的句子①改為被動(dòng)句。
So it is not surprising that _____________________by the World Wide Fund for Nature.
【小題3】Why are the giant pandas endangered?
【小題4】Give a way to help the giant pandas in the wild, please.

One day in April, a special activity called“Food Street”was held on the playground at Railway No. 1 Middle School in Xi’an.
