A、S波、P波的波速都明显下降

B.S波完全消失，P波的波速突然下降

C.S波、P波的波速都明显增加

D.P波完全消失，S波的波速突然下降

A.左右摇晃 B.先上下颠簸后左右摇晃

C.上下颠簸 D.先左右摇晃后上下颠簸

【答案】

【1】A

【2】C

【3】B

【解析】

试题分析：

【1】此次地震发生后，地震波横波（S波）和纵波（P波）的传播速度在向上经过莫霍界面时发生的显著变化是都明显下降，故选A。

【2】由材料可知，地震震源深度达60千米，应位于上地幔中，故选C。

【3】地震波横波和纵波都能通过地壳和地幔，在地壳中传播速度慢，在地幔中传播速度快，此次地震震源深度达60千米，应位于上地幔中，当地震发生时，纵波传播速度快，爪哇居民先感到上下颠簸，然后横波传来，人们感到左右摇晃。故选B。

Polar bears live in such environment that is too cold for most animals. For much of the year, they live and hunt on the 1 (freeze) Arctic sea ice. Nature has prepared them for the cold conditions but nothing has prepared them for the danger 2 threatens(威胁) their only home.

The polar bears’ world is melting. Polar bears 3 (suffer) in a warmer world are in danger. Studies show that the polar ice 4 (reduce) by 9.8% every 10 years since 1978.At present , about 20,000 to 25,000 polar bears live in the Arctic. Polar bears depend on the sea ice for their 5 (survive). ＂The sea ice is more than just the platform that the bears walk 6 ,＂ says Andrew Derocher, who studies North American polar bear populations. ＂Without 7 , they can’t exist.＂

Some melting and refreezing of the polar ice is natural. But in a 8 (warm) world, these cycles speed up, and bears have less time to hunt. 9 (normal), they have three months in the spring when they gain more weight and the extra fat is used later, 10 the bears are not actively hunting. Therefore, it is urgent to protect the environment and maintain the ecological balance.

【题目】C

Many of us still tend to think that emotions can affect reasonablethought，and sometimes land us in trouble.But in recent years psychologists have taken quite a different view.Keith Oatley，Professor of Psychology at Glasgow University，is involved in the research which shows the fundamental importance of emotions.

He believes we_are_very_ambivalent_about_them：we think of our emotions as being unreasonable，but we also consider them as essential to being human.For example，Mr Spock，a character in the television series Star Trek，is superintelligent and he has no emotions at all.However，he is never made captain of the spaceship.Maybe，this is because Mr Spock is not the kind of person you can share your feelings with—a person who shows his emotions.

As Professor Oatley points out，our emotions have very important functions，for example，fear.If we cross the road and a car approaches，we usually stop moving or step back.We stop what we are doing，check what we have done and pay very careful attention to the environment.The emotion of fear makes us take this small series of actions which，on average，help preserve our safety.

On the other hand，if things are going well and small problems come up，we find we can solve them with the resources we have to hand.As a consequence，we tend to feel happy and usually continue doing the job.

Anger is an emotion that tends to occur when someone is preventing us from doing something.Then this small “kit” of reactions enables us to prepare ourselves to be quite aggressive to that person，or to try harder，and so on.

Professor Oatley believes emotions generally ocur at these important moments in actions.With fear and anger our emotions make us decide to start doing something else，while with happiness they “suggest” we continue what we are already doing.

【1】What’s Keith Oatley’s opinion about emotions?

A．They affect reasonable thought.

B．They get us into trouble.

C．They are helpful to us.

D．They are reasonable.

【2】What does the underlined part “we are very ambivalent about them” in Paragraph 2 mean?

A．We have contradictory feelings towards emotions.

B．We have similar ideas of emotions.

C．We are quite clear about emotions.

D．We can do nothing about emotions.

【3】It can be inferred from the passage that________.

A．we must control our emotions in daily life

B．emotions play a more important part than we realize

C．positive emotions such as love and joy are good for us

D．negative emotions make us continue what we are doing
