Mercury(水星) is the closest planet to the sun. It is a planet slightly larger than the Earth’s moon. It is covered in craters. Some craters have ice in them, even though the planet is hot. Sunlight never touches some parts because of the planet’s special position. Without air, there are great temperature differences between the coldest and hottest parts. Mercury days are so long that there are big differences between temperatures on the daylight side and the night side.

Mercury was created billions of years ago, when big rocks ran into each other. After these accidents, the planet was frequently visited by meteorites (流星) for several hundred million years. There were also many volcanic eruptions. As the planet cooled, the thin, rocky outside shell reduced in diameter(直径) by about 3 kilometers.

The Caloris Basin is one of the largest craters on Mercury. This big crater is 1, 300 kilometers wide and was formed when a large rock, about 100 kilometers across, knocked into the surface. Beethoven, another large crater, is 643 kilometers across.

The cliffs on Mercury are up to 2 kilometers high and hundreds of kilometers long. The cliffs were formed when the thin surface fell apart, as volcanic activity slowed down and Mercury became cooler.

One Mercury day lasts about 59 Earth days. Mercury takes about 88 Earth days to have a complete year, instead of the 365 days that we have on the Earth. Mercury speeds around the sun so that there are three Mercury days every two Mercury years! Mercury has a strange relationship with the Earth. Every 117 days, when Mercury is closest to the Earth, it always has the same side facing us.

Mariner 10 is the only spacecraft to visit Mercury. It made three visits to Mercury in, the 1970s, taking photos of many cliffs and craters. Although the first three visits answered many questions, they have raised others.

1. What is the surface of Mercury like?
A.It’s generally flat.B.It’s hot everywhere.
C.It’s bright everywhere.D.It’s cold in some parts.
2. Why did Mercury’s diameter get smaller?
A.A drop in temperature changed its size.
B.A great many meteorites ran into it.
C.It got out of shape as time passed.
D.Lots of surface rocks fell off.
3. What do we know about Mercury?
A.One Mercury day lasts about 88 Earth days.
B.It turns around the sun faster than the Earth.
C.Six Mercury days are two Mercury years.
D.It has more cliffs than large craters.
4. What happened after Mariner 10’s three visits to Mercury?
A.Another spacecraft visited Mercury.
B.New cliffs and craters were formed.
C.New signs of volcanic activity appeared.
D.Lots of new puzzles needed to be solved.

文章大意:本文为一篇议论文。体育运动既是对人的体力的挑战,也是对人的心理的挑战。在体育运动中,父母和教练应对孩子多鼓励,少批评,让孩子用积极的心态去迎接挑战。

【推荐1】Sport is not only physically challenging, but can also be mentally challenging. Criticism (批评) from coaches, parents and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress can be physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping out of or quitting an activity that was at one time enjoyable.

The early years of growth are important years for learning about oneself and the sport setting is one where valuable experiences can take place. Young athletes can for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents and coaches’ criticisms to heart and find faults in themselves.

Coaches and parents should also pay attention that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport an other life lessons. In today’s youth sport setting, young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game, many parents and coaches focus on the outcome and find faults with youngsters’ performances. Positive support should be provided regardless of the outcome. Research indicates that positive support encourages and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.

1. What is the main idea of the first paragraph?
A.Sport can be mentally challenging.
B.Stress should be made less.
C.Mental stress should be reduced.

A.It enables them to criticize themselves.
B.It can provide them with valuable experiences.
C.It can help them learn more about society.
D.It teaches them how to set realistic goals for themselves.
3. What should parents and coaches do according to the passage?
A.Train children to deal with stress.B.Help children to win every game.
C.Make sure children enjoy sport.D.Understand the meaning of sport.
4. What’ s the author’ s purpose of writing the passage?

文章大意:这是一篇说明文。文章主要说明了人们对赞美和批评有不同的反应,但是太多的赞美会让人们失去兴趣,因此建设性的批评才有助于成为更好的人。

【推荐2】There is no doubt that when you receive a compliment, you feel good and when you receive a criticism, you feel upset and want to refuse it.

You shouldn’t be surprised by your reaction to the negative comment, as it’s human’s survival mechanism to avoid being criticized. Clearly, we don’t want to be seen as failures, so we’d rather shut our eyes and cover our ears than have to take any criticisms from others.

Imagine you’re learning to play the guitar, and you have just done your first public performance. Your teacher says, “You did well,” which may not be as useful in helping you improve your performance skills as “Your timing needs some work.” So I believe that criticisms are better than compliments.

No one would argue that healthy nutrition is a bad thing. However, too much food or drink — no matter how healthy they may be — can make us ill. Too many compliments take us away from our original enthusiasm of enjoying an activity. We start doing the activity only for the sake of receiving self-satisfying praise. Without the expectation of praise, our enthusiasm to complete things begins to be lost.

Launched in 2010, Microsoft KIN only lasted on the market for 48 days. It was very obvious that most 15 to 30-year-olds preferred Androids, BlackBerrys and iPhones to the Microsoft KIN. If criticism and feedback from the target group had been received while the phone was in development, Microsoft KIN could have avoided the huge embarrassment and its final failure.

Just to be clear, I’m talking about constructive criticism, which I like to think of as “healthy criticism”. The right kind of criticism is honest feedback that will benefit you. Feedback forces you to reconsider your actions and the way you work. If you use constructive criticism wisely, it can guide you away from bad practices, giving you support and courage to move forward to be a better person in the future.

1. What can we learn about compliment and criticism in Paragraph 1?
A.People’s response to them.B.People’s ways to express them.
C.People’s understanding of them.D.People’s different opinions on them.
2. How would people be when receiving too many compliments?
A.More annoyed.B.More satisfied.C.Less worried.D.Less interested.
3. How can healthy criticism be helpful according to the last paragraph?
A.To encourage growth.B.To develop intelligence.
C.To avoid embarrassment.D.To reduce enthusiasm.
4. What is a suitable title for the passage?
A.Criticisms are better than compliments.
B.Constructive criticism contributes to better future.
C.Honest feedback comes from healthy criticism.
D.Enough enthusiasm is vital for further development.

【推荐3】The term “Pygmalion effect” was coined in reference to studies done in the 1960s on the influence of teacher expectations on students’ IQs. The studies asked if teachers had high expectations, would those expectations become self-fulfilling prophecies (预言)regardless of initial IQ? In that particular case, years of debate and analysis have resulted in the conclusion that the effects were negligible.

However, the concept of the Pygmalion effect—expectations influencing performance and becoming self-fulfilling prophecies —is widespread. Many people have stories of achieving something just because someone had especially high expectations of them.

The Pygmalion effect suggests our reality is negotiable and can be influenced by others — on purpose or by accident. What we achieve, how we think, how we act, and how we perceive our capabilities can be affected by the expectations of those around us.

An interesting use of the Pygmalion effect might be that suggested by George Bernard Shaw's play Pygmalion. In it, Professor Henry Higgins takes a poor flower seller from the streets, Eliza Doolittle, and by giving her lessons helps her sound like a duchess(公爵夫人). Being able to speak like a member of the upper classes is meant to open doors and give her opportunities that she would otherwise never have. Eliza finally appears to be a duchess as Higgins wishes. The expectations people have of us affect us in countless subtle(微妙的) ways each day. Like Eliza Doolittle, those expectations affect the opportunities we are offered, how we are spoken to, and the praise and criticism we receive.

Individually, these may have minimal impact. In the long run, however, they might decide whether we succeed or fail or fall somewhere on the range in between.

The Pygmalion effect is best understood as a reminder to be mindful of the potential influence of our expectations. Even if the effect is small, having high expectations in many situations can only inspire others regarding their own capabilities. People’s limitations can be stretched if you change your perception of their limitations. A lot of what we accomplish in life is done in groups. If you want the people around you to have success, you can try raising your expectations. If you expect the worst, you’ll probably get it.

1. What does the underlined word “negligible” in Paragraph 1 probably mean?
A.Slight.B.Unusual.C.Important.D.Shocking.
2. What can we learn from the passage about the Pygmalion effect?
A.It works better in individuals than in groups.
B.It takes effect only in the field of education.
C.It stresses people’s expectations on others.
D.It can increase people’s initial IQ.
3. The author illustrates the use of the Pygmalion effect in Paragraph 4 mainly by________.
A.making a comparison
B.providing an example
C.introducing an approach
D.presenting an assumption
