The world is not hungry , but it is thirsty . It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink and use the 3% - the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted .
　　Now more water is needed. The problem is: Can we avoid (避免) a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it . Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers . But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
　　The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it's already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up.
小題1:The world is thirsty because ________.
A．3/4 of the earth is covered with water
B．we have enough sea water to use directly
C．we haven't used all the water in rivers and lakes
D．a(chǎn)bout 97% of water on the earth can't be drunk or used for watering plants directly
小題2:Which of the following is true ?
A．3% of water on the earth is in rivers and lakes.
B．75% of water on the earth is the sea.
C．97% of the earth is covered with water.
D．3% of water on the earth is sea water.
小題3:From the passage we learn _________.
A．if every city reuses its water, we'll be in no danger of drying up
B．man can only drink and use about 25% of water on the earth
C．today in most large cities water is used only once
D．water can be used only once
小題4:To avoid the serious water shortage , which of the following is the most important?
A．Save water and try to make good use of the water in rivers and lakes.
B．Don't pollute water and keep all rivers and lakes clean.
C．Make dirty water clean and then reuse it.
D．Try to find a cheaper way to get the salt out of the sea water.
小題5:The name of the passage would be ________
A．The Sea Water 　　　B．How to Save Water　
C．The Thirsty WorldD．The Polluted Water

小題1:D

試題分析：地球不僅是饑餓的還是干渴的，因?yàn)槲覀冎荒苁褂萌蛩值?%。為了避免缺水，我們首先要節(jié)約用水，其次是要找到再利用水的方法。最好的答案是從海水中分離出鹽，但是這個(gè)方法成本很高�？茖W(xué)家們還在不斷努力以找到經(jīng)濟(jì)有效的辦法。
小題1:細(xì)節(jié)理解題。短文第一段提出了問(wèn)題，也給出了答案Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly.“因?yàn)榈厍蛏?7%的水是海水，我們不能直接飲用或用它們來(lái)澆灌植物。”所以答案是D。
小題2:推理判斷題。短文說(shuō)到：Man can only drink and use the 3% - the water that comes from rivers and lakes“人們只能飲用和利用其中的3%，這3%的水來(lái)自河流和湖泊”。因此河流和湖泊的水只占全球水的3%，故選A。
小題3:細(xì)節(jié)理解題。Today, in most large cities water is used only once and then runs to the sea or rivers .“今天，在大多數(shù)大城市水只是利用過(guò)一次就流入大海和河流”。由此可知，答案是C。
小題4:細(xì)節(jié)理解題。短文最后一段說(shuō)最好的答案就是海洋，就是從海水中提出鹽，但是很貴，科學(xué)家們?cè)趯ふ伊畠r(jià)的辦法從海水中提出鹽。所以，找到便宜的辦法才是最重要的。故選D。
小題5:細(xì)節(jié)理解題。短文先介紹了地球的水資源很有限，接著講了避免水缺乏的方法。所以文章的主題中心詞就是thirsty，故選C。

Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper -- a little bird called a honey guide.
The honey guide does not actually like honey, but it does like the wax(蠟) in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them tot he nest. When they finally arrive at the nest, the follower reaches in to get the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always fall to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined (下決心) in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper(養(yǎng)蜂者) is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

For a long time, humans have used technology (科技) to study the world around us, and Mars is the latest place we’re using machines to explore. Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.
Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines’ safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet.
But the trips made by Spirit and Opportunity were dangerous. Mars is often called the “death planet”, because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart (分裂) near the earth.
小題1:For a long time humans think ________.
A．they can surely find life on Mars
B．there may be life on Mars
C．it’s too late for them to explore Mars now
D．Mars is the only planet that has life on it
小題2:The two robots ________.
A．have found out that it is warm and wet on Mars
B．were sent to Mars to find some stones
C．were the first two American robots that landed on Mars
D．a(chǎn)re the only machines that have landed on Mars so far
小題3:The third paragraph mainly tell us ________.
A．it’s a very hard and dangerous trip for spaceships to Mars
B．two-thirds of the spaceships sent to Mars have failed
C．Spirit and Opportunity landed on Mars successful
D．Mars is called the “death planet”
小題4:From this passage we learn that ________.
A．the two robots have found water on Mars
B．Opportunity touched on Mars a week later than Spirit

January 16, 2014 – We know the saying “The early bird gets the worm”, but today you’re going to  learn about the interesting saying “The early fish gets the bird.”
An African tigerfish(老虎魚) was seen jumping out of the air and catching a flying bird. The African tigerfish has bright red fins and very sharp teeth. There have been rumors(傳聞) this kind of fish preys on(捕食) birds since the 1940s, but no one was able to catch one.
"The whole action of jumping and catching happens so quickly that after we saw it, it took all of us a moment to really understand what we had just seen," said Nico Smit from Environmental Sciences and Management at North-West University.
Smit and his research team saw it at a lake in the Mapungubwe National Park in South Africa during summer. They found about 20 fish feeding on birds in the morning. Those birds may be out early to look for food, but we will never know for sure!
