Penguins are lovely animals. Most people like them. But now as many as 10 of the 17 kinds of penguins are in danger of disappearing. The number of penguins has decreased by ( 減少了) 30% since 1987.
Penguins are black and white birds that live in the southern part of the world. They are common in the Antarctic Continent (南極大陸) ,New Zealand, Australia and South America. Many live near cold waters (水域). But some live near warm waters in Galapagos Islands. Penguins  cannot fly, but  they are fine swimmers. The shape of their body helps them to survive. Penguins eat fish and krill  (磷蝦). They have short wings that help them to dive up to 900 feet to catch larger fish. They can swim 10-15 kilometers an hour which lets them protect themselves. They also have lots of body oil that helps in keeping them dry in the water.
The warming of the earth is the reason for the decrease in the number of penguins. The hotter and hotter air has caused ocean waters to become warmer. Higher water temperature has decreased the fish and krill. Some years later these birds are completely unable to reproduce. And many adult penguins die of hunger.
Too much fishing, exploration for oil and oil leaks (泄漏) also make penguins be in danger. Poisonous things in ocean waters are another danger. Penguins also have their enemies, including sharks, seals and sea lions.
小題1:Penguins can do the following except________.
A．divingB．flyingC．swimmingD．catching fish
小題2:Which of the following is NOT the reason for the decrease in the number penguins?
A．The warming of the earth.B．Too much fishing.
C．Natural disasters.D．Poisonous things in ocean waters.
小題3:What does the underlined word "reproduce" mean?
A．繁殖B．滅絕C．遷徙D．覓食
小題4: What’s the passage mainly about?
A．Fish and krill have decreased.
B．Ocean waters are polluted.
C．Sharks and seals are the enemies of pen­guins.
D．The decrease in the number of penguins.

小題1:B
小題1:C
小題1:A
小題1:D

本文講的是企鵝數(shù)量的減少以及減少的原因。
1. B 此題是細(xì)節(jié)題。從Penguins cannot fly, but  they are fine swimmers可知企鵝不能飛，選B。
2. C 此題也是細(xì)節(jié)題。文章講了三個(gè)企鵝減少的原因，從三、四、五的第一句可知C答案不正確，文章并沒有說到的，A,B,C都符合題意。
3. A 此題是考查單詞的意思。這里講的是企鵝減少的第一個(gè)原因，水溫的升高導(dǎo)致魚和磷蝦的減少，從而導(dǎo)致企鵝不能繁殖，因?yàn)槿鄙偈澄�，故選A。
4. D 這是個(gè)對(duì)全文的中心思想歸納題，很明顯全文講的是企鵝的減少及減少的原因，選D。

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon. They don’t feel hurt. If the same two people meet again, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand .Friendships between us develop more slowly but may become lifelong feelings, extending（延伸）deeply into both families.
There is another difficult point for us to understand. Although Americans treat friends warmly in their personal everyday lives, they don’t show their politeness to them if it requires a great deal of time. But in China, we are usually generous with our time. We, as hosts, will appear at an airport even in the middle of the night to meet a friend. We may take a day off from our work to act as guides to our friends. It is opposite in America. Americans cannot manage the time to do a great deal with a visitor outside their daily plans. They will probably expect the visitors to get themselves from the airport to the hotels. And they expect the visitors will phone them from there. Once the visitors arrive at their homes, the welcome will be full, warm and real.
For Americans, it is often considered more friendly to invite a friend to their homes than to restaurants, except for business matters. Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. So accept their hospitality（好客）at home and enjoy your visit in America!
小題1: The underlined phrase "pick up" in Paragraph 1may mean "_________________".
A．put downB．give upC．pay no attention toD．continue
小題2: From the passage, we can know_________________.
A．Americans are always generous with their time.
B．Americans don’t feel hurt if their friendships disappear soon.
C．Chinese friendships develop more slowly but will never disappear.
D．Chinese friendships develop faster than American friendships.
小題3:This passage is most probably written for __________________.
A．American studentsB．Chinese students
C．Chinese visitors to AmericaD．American visitors to China

A Nobel Prize(諾貝爾獎(jiǎng)) is considered by most people one of the highest international honors a person can receive. As you know, the prizes were started by a Swede(瑞典人) called Alfred Nobel. He was born in Stockholm, the capital of Sweden. Alfred Nobel was a great scientist. He made two important inventions, and so he became very rich. Although he was rich, Nobel was not a happy man. He never married or had children. Also, he was a sick man during his large part of life. When he died at the age of 63, he left a fund(資金) of $9,000,000. The money was to be used in giving prizes to those who made great achievements in physics, chemistry, medicine and literature(文學(xué)), and for world peace.
The first Nobel Prizes were given on December 10, 1901, five years after Nobel’s death. Since then many famous people from all over the world have been given Nobel Prizes for their achievements.
Each prize has three parts. The first part is a gold medal. Second, a winner of a Nobel Prize is given a diploma saying that he has been given the prize. The third part of the prize is a large amount of money-about $40,000.
Often a prize is given to just one person, but not always. Sometimes a prize is shared. It may be given to two or more people who have worked together. It is also sometimes true that a prize is not given at all if there is no great achievement. In 1972, for example, no Nobel Peace Prize was given.
小題1:When was Alfred Nobel born?
A．In 1938.B．In 1833.C．In 1896.D．In 1906.
