Is there a strange something high up in the world’s tallest mountains? If so, is it a big bear? Is it a monkey? Or is it a kind of man? No one knows. This mystery has puzzled the world for years.

In 1887, a mountain climber found large footsteps in the snow. They looked like the footsteps of a very large man. But men don’t walk without shoes in the snow!

In 1906, another climber saw more footsteps. He saw a very large animal standing on two legs. As he watched, it ran away very quickly. Fifteen years later, a newspaper had new stories about the “something”. A mountain climber said he had seen the “snowman” walk slowly in the snow. He said it looked like a very large man.

From then on, more and more people had stories to tell. But not until 1951 did a mountain climber bring back the pictures of large footsteps. The pictures showed clearly that the snowman walked on two legs. So it was not a bear or a monkey. Could it be an apeman (猿人)? And the mystery keeps growing. Some day, we may find out just what it is that makes the largest footsteps.

文章大意:本文是一篇说明文,主要讲的是通过练习,我们可以提高我们的创造力。

【推荐1】Most of us would like to be more creative, but we assume there is little we can do about it. Psychology professor K. Anders Ericsson claims that with enough practice, any of us can become experts. However, he is quick to add that this requires a specific kind of practice that Ericsson calls ‘deliberate practice’: that is, pushing beyond one’s comfort zone and setting goals that are above one’s current level of performance. He says he has yet to find the limits on being successful and he doesn’t believe them to be real.

Ericsson has looked primarily at artistic and athletic skills, but can these findings apply to creativity? Most experts agree that even if most people cannot hope to become creative geniuses, they can learn to become more creative through practice. Psychologists claim that there are actually two levels of creativity, which they refer to as’Big C’ and ‘small c’. Big C creativity applies to breakthrough ideas, ones that may change the course of a field or even history. Small c creativity refers to everyday creative problem solving, like creating a new recipe or improving a process, which psychologists subdivide further into similar and different thinking. Similar thinking involves examining all the facts and arriving at a single solution. In contrast, different thinking involves coming up with many possible solutions. What most people think of as creativity generally involves different thinking and can be taught, practised and learnt.

Even with practice, different thinking alone cannot make one creative, however. Scott Barry Kaufman, a cognitive psychologist, says that most creative people share one personality quality: openness to new experience. Since this quality and these processes have been identified, less creative people can try to emulate them. Normally, we tend to reproduce what we already know because creative ideas move us into unfamiliar territory involving risks and following the usual behaviors is comfortable.

Moving outside of our comfort zone, engaging indeliberate practice and tolerating contradictory ideas, risk and failure are all things we can learn to do better. It is unlikely that doing so will transform any of us into creative geniuses, but it does have the potential to increase our level of creativity.

1. Why does Ericsson think he can’t find the limits?
A.No restrictions exist.B.Practice makes perfect.
C.Each one can succeed.D.The goal is ambitious.
2. Which of the following is an example of ‘small c’?
A.Settling in outer space.
B.Building a plastic doghouse.
C.Developing robots to look after the old.
D.Explaining the theory of evolution in class.
3. What does the underlined word “emulate” in paragraph 3 mean?
A.Justify.B.Limit.C.Copy.D.Assess.
4. What message does the author seem to convey in the text?
A.We can learn to be more creative.
B.Life is full of various challenges.
C.It’s better to take deliberate practice.
D.Most can become creative geniuses.

文章大意:本文是一篇说明文。最新的研究表明,宽吻海豚能够通过味道来识别朋友。

【推荐2】Researchers have long known that dolphins(海豚)can identify each other with signature whistles, the specific calls they use to refer to themselves. Now, a new study shows that the sense of taste allows bottlenose dolphins to identify their friends through urine-liquid waste from their bodies.

Study leader Jason Bruck, from Stephen F. Austin State University in Texas, initially wanted to test whether those signature whistles work similarly to human names. He needed a second way for dolphins to identify each other. To find out if dolphins could associate a whistle with a specific dolphin, Bruck turned to urine. A scientist had previously observed wild dolphins purposefully swimming through each other’s urine, leading Bruck to suspect they were gathering information from it.

Over evolutionary time, bottlenose dolphins have lost their sense of smell but kept a strong sense of taste. For the first part of the experiment, the team presented eight dolphins with urine samples from familiar and unknown individuals, and found that the dolphins spent about three times longer time exploring the familiar urine than the unfamiliar urine, with a few individuals collecting the familiar urine for more than 20 seconds. The dolphins paid little attention to the unfamiliar urine.

Then, for the second part, the researchers tested whether an individual’s whistle and urine were connected in their minds. They paired urine samples with recordings of characteristic screams played on underwater speakers, matched either by the same dolphin that provided the urine or by another animal. It turns out that the dolphins spent more time next to the speaker when the whistles corresponded to the urine sample. This indicates they can recognize each other in more than one way.

Using taste could be beneficial in the open ocean, as dolphins would learn from urine the recent presence of an individual. Given the recognition abilities shown in the study, the researchers think that it is possible that dolphins can also extract other information from urine, such as reproductive status or the use of pheromones(外激素)to influence the behavior of others.

1. What is paragraph 2 mainly about?
A.The swimming style of dolphins.
B.The cause of experimenting with urine.
C.The way of dolphins addressing each other.
D.The similarities between humans and dolphins.
2. How did the dolphins respond when exposed to a correct urine-whistle pair?
A.They screamed at the speaker.B.They paid little attention to whistles.
C.They stayed near the speaker longer.D.They got scared enough to flee the area.
3. What does “extract” underlined in the last paragraph mean?
A.Process.B.Confirm.
C.Obtain.D.Convey.
4. What does the author intend to tell us about the dolphins?
A.They have a strong sense of hearing.
B.They can recognize their friends by taste.
C.They can form close friendships through sound.
D.They use signature whistles to identify themselves.

文章大意:这是一篇说明文。介绍了人们为什么假期反而越休息越累。

【推荐3】Next time you go on holiday, you might find yourself feeling even more tired than usual.

While this can often be attributed to jet lag, there can often be other reasons why you need to sleep more than usual.

You’ve got “leisure sickness”

You may find yourself burning out at work right before you go on holiday.     1    . This then spreads into beach time. Stress levels are found to make the immune system less effective-which sounds about right when you’re trying everything up before you leave the office.     2    .

You’re catching up with sleep

Most of us don’t get enough sleep in our day-to-day lives. So heading on holiday and being allowed to sleep as much as you like can be a comfort.     3    , you can forget what it feels like. Letting your body relax and catch up on that much-needed sleep can leave you feeling more sleepy because you’ re realizing what you’ re missing in your everyday life in terms of sleep.

You’re putting your brain on high alert

You may not feel as relaxed in a foreign bed, which can cause the left side of your brain to stay alert for “danger”.     4    . If you travel regularly, your brain can get better at learning to turn that function off.

    5    

If you’re someone who finds it hard to sit around and do nothing on holiday, then it might be that packed journey that has got you yawning. Planning an 8 am sharp boat trip followed by sightseeing before lunch and a museum visit in the afternoon can be pretty exhausting. If you can spare at least a day on holiday, you’ll feel far less tired of the rest of it, when you get back to your jam-packed journey.

A.You haven’t finished your plan
B.You’re doing loads of activities
C.But if you haven’t been fully rested for a while
D.The good news is that humans' brains are very flexible
E.It is because you have so much work to get finished before you leave
F.Thus people who are often in new places may not necessarily have poor sleep on a regular basis
G.This can also be applied to getting everything packed, prepared and sorted before you leave the house
