But we believe at the beginning of the eighteenth century there were 105,000 humpback whales and 120,000 right whales. At the beginning of the twentieth century there were 75,000 humpbacks and 80,000 rights. Since 1900 their numbers have fallen very quickly. Between 1935 and 1950 the number of humpbacks fell from 20,000 to 10,000 and since 1950 the number has fallen to only 6,000. The number of right whales has fallen even faster. In 1935 there were 25,000. The number fell to 6,000 in 1950 and since 1950 the number has fallen to 4,000. Men have always been hunters. Thousands of whales have become victims . It's time to do something to protect whales. Question: The number of right whales has fallen _ . - more slowly than that of humpback whales - faster than that of humpback whales - as slowly as that of humpback whales - as fast as that of humpback whales

Read the following article and select the best answer. Article: The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid--we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink. However, several types of animals can walk on water. One of the most interesting is the common basilisk. Basilicus, a lizard native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we'd need huge feet that we could bring up to our ears in order to create adequate "hitting. " But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a "non-Newtonian" liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour. Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice, if you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward! Question: What is the author's attitude toward the idea of humans' walking on water? - It is risky but beneficial. - It is interesting and worth trying. - It is crazy and cannot become a reality. - It is impractical though theoretically possible.
It is impractical though theoretically possible.

Read the following article and select the best answer. Article: Most people call it "body language" -- the clues to the meaning that we get from gesture, facial expressions, posture -- everything that isn't spoken.Experts call it "nonverbal communication," but it means the same thing: a second source of human communication that is often more reliable to understanding what is really going on than the words themselves. Understanding body language is important to success, whether in the business world or in our personal lives.However, most of our ideas about body language are wrong, according to modern communication research. There is a belief that people with shifty eyes are probably lying.As Paul Ekman says, "When we asked people how they could tell if someone was lying, too much blinking and shifty eyes were the winners.But sometimes people act like that because they are shy.Liars pretend to be calm in order not to be caught. Ekman goes on to argue against such a wrong belief.Although this kind of body language is probably an expression of nervousness, it is not always because the person is lying.Shyness can, for example, make people shift their eyes.To understand what someone's behavior means, you have to watch them carefully. There is also a belief that when meeting someone, the more eye contact , the better.As a result people would like to make initial contact in formal situations, like a job interview, by staring fixedly at the other human.Yet Ekman points out that most of us are comfortable with eye contact lasting a few seconds, but any eye contact that is longer than that can make us nervous. In short, you must carefully consider the speaker and the speaking environment.Experts suggest that unless you know about someone's basic communication style, you will have little hope in understanding their true feelings through body language.In other words, body language carries important but not always true messages. Question: From the passage we can learn that _ . - there is no doubt that a liar has shifty eyes - people sometimes blink because of shyness - eye contact lasting a few seconds can make us nervous - understanding body language is more helpful in business
people sometimes blink because of shyness
