Huge Waves Destroying Arctic Ice Faster than Expected
Ice covers much of the Arctic Ocean（北冰洋）．Some pieces of ice are huge， like moving islands． As temperatures have increased， however， some of the ice has begun to disappear． Scientists have discovered huge waves（海浪）in the arctic waters．
The waves were discovered by accident in May， 2010．Scientist Aleksey Marchenko and his students set out on a trip． They wanted to study the icy waters．
On May 2， the ship traveled east and stopped next to a large chunk of ice．around 50 miles from the small island of Hopen．Marchenko prepared to lead his students out onto the Ice
"We were ready to go but when I went out， I discovered many cracks（裂缝）around，" he remembers．
He decided to move the ship deeper into the ice to keep safe． The farther in they went， he thought， the harder the ice would become． As they pushed forward，however， the ship experienced small waves， and then bigger ones．Soon， the waves broke up the ice around the ship into thousands of smaller pieces．
Within an hour， Marchenko and his team saw a wave that was about 13 feet high． The ship's navigation（航行）system finally recorded the largest waves．They were more than 20 feet in height． The waves were so strong that they forced huge pieces of ice to jump up and down， breaking the ice into smaller pieces within just one hour． Scientists had never imagined that the process could happen so fast． The waves in these areas used to be small．
The speed and force of the huge waves there makes it impossible to know in advance when they are coming． That could be dangerous for navigators and local communities who are unprepared for huge waves or depend on sea ice to protect them． Wildlife like polar bears and walruses that depend on sea ice to live is also in danger．
Some scientists think people will soon see even bigger waves in these icy waters．As waves break up ice， the seas will become more open， and the waves will get even stronger． There are stormy times ahead．
（1）When did Marchenko and his students discover huge waves in the arcticwaters？
（2）Why did Marchenko and his students set out on the trip？
（3）What did Marchenko decide to do to keep safe？
（4）How high were the largest waves recorded by the navigation system？
（5）What is Paragraph 7 mainly about？

If someone asks me, “Do you like music?” I will answer him or her, “Of course, I do.” Because I think music is an important part (部分) of our lives.
Different people have different ideas about music. For me, I like rock music (摇滚乐) because it’s so exciting. And my favourite rock band (乐队) is Foxy Ladies (酷妹). I also like pop music. My classmate Li Lan loves dance music, because she enjoys dancing. My best friend Jane likes jazz music (爵士乐). She thinks it is really cool.
“I love dance and rock music very much,” says my brother, “because they are interesting.”
But my mother thinks rock is boring. “I like some relaxing (轻松的) music,” she says. That’s why she likes country music, I think.

One way that scientists (科学家) learn about man is by studying animals．In this lab, the scientists are studying the relationship between diet and health．
They are studying the relationship between the amount (数量) of food the mice eat and their health．The mice are in three groups．All three groups are receiving the same healthy food．The first group is eating one cup of food each day, the second group is eating two cups, and the third group is eating three cups．
After three years, the healthiest group is the one that is only eating one cup of food each day．The mice in this group are a little thinner. But they are more active．Most of the day, they are running, playing with one another．Also, they are living longer．Mice usually live for two years．Most of the mice in this group are still alive after three years．
The second group of mice is healthy, too．They are active, but not as active as the thinner mice．They are only living about two years．
The last group of mice is receiving more food than the other two groups．Most of the day, these mice are eating or sleeping．They are not very active．These mice are living longer than the scientists thought－about a year and a half．But they are not healthy．They are sick more often than the other two groups．People give each group of the mice _______ amount of food every year.
| A．a different | B．the same |
| C．a small | D．a large |
The experiment (实验) lasted for at least _______ years．
| A．one and a half | B．two |
| C．two and a half | D．three |
The underlined word “they” in the second paragraph refers to _______.
| A．the scientists |
| B．the mice in the first group |
| C．all the mice |
| D．the mice in the last group |
The best title for the passage is ________．
| A．Man and health | B．Diet and animals |
| C．Diet and health | D．Animals and human beings |
The result of the experiment mainly shows that ________．
| A．eating less may bring longer life |
| B．the mice eat more than the scientists thought |
| C．the mice live longer than the scientists thought |
| D．the more exercise you take, the healthier you will be |
