Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.
The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety－five would have the same effect.
Some scientists have suggested setting a noise limit of one hundred and twenty decibels in the oceans. They have observed that noises at that level can frighten and confuse whales(鲸鱼).
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals.
The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists don't think that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean. According to the passage, natural sounds include all of the following EXCEPT________.
| A．sounds made by animals themselves |
| B．ocean drilling |
| C．underwater earthquakes |
| D．the breaking of ice fields |
Which of the following is true of whales？
| A．They won't be confused by noises. |
| B．They are deaf to noises. |
| C．Their ability to reproduce will be lowered by highlevel noises. |
| D．Their hearing will be damaged by highlevel noises. |
According to the passage, what will scientists most probably do in the future?
| A．They will work hard to reduce ocean noise pollution. |
| B．They will protect sea animals from harmful noises. |
| C．They will try to set a limit of 120 decibels. |
| D．They will study the effect of ocean noise pollution. |
Dear Betty,
My roommate’s family wants me to celebrate Thanksgiving Day with them in their home. I accepted the invitation, and I’m excited about going, but I’m a little nervous about it, too. The social customs in my country are different from those here, so I’m a little worried about making mistakes.
Should I bring a gift, such as candy or flowers? Should I arrive on time or a little late? At the dinner table, how can I know which fork or knife to use? How can I let the family know that I’m thankful for their kindness?
Yours,
Knowing Nothing
Dear Knowing Nothing,
It’s a good idea to bring a gift when you go to a dinner party. Flowers are always welcome, or you can bring a bottle of wine if you know the family drink it.
You should arrive on time or five to ten minutes late. Don’t get there early. If you are going to be more than fifteen minutes late, you should call and tell them.
Try to relax at the dinner table. If you don’t know how to use the right fork, knife or spoon, just watch the other guests, and follow them. If you still have no idea of what to do, don’t be shy about asking the person next to you; it’s better to ask them than to be silently uncomfortable and nervous.
If you like the food, say so. Of course, you’ll thank the host and hostess for the meal and for their kindness. It’s also a good idea to send a card to thank them the day after.
Yours,
Betty Knowing Nothing wrote a letter to Betty to _____.
| A．tell Betty some good news | B．ask for some advice |

One night last February, a seventeen-year-old Duffy drove home along a winding road, he saw a strange light thrown against the tree. “I knew it wasn’t the moon”, he said. “I drive this road all the time and I notice little things out of place.”
Duffy stopped his car and got out to examine. Below him far down in the deep valley lay a broken car with its headlights on. Thirty minutes earlier, a man had driven off the edge of the road, which has no guardrail. His car fell and rolled end over end, landing on its top more than two hundred feet below.
Duffy rushed to call for help, then returned and got down to reach the injured driver. Snow covered the valley and the temperature was below freezing. After struggling back up the cliff, Duffy took off his jacket and shirt and wrapped the injured man in time, along with the blankets from his car.
Life-saving deeds are starting to become usual action for Duffy, the oldest of seven children. When he was 12, he saved his ten-year-old brother from drowning. Two years ago, his three-year-old sister ate rat poison, and Duffy cleaned out her mouth, make her drink milk to protect her stomach and called doctors.

This is a true story from Guyana. One day, a boy took a piece of paper from a box. He made a paper ball and pushed it into his nose. He couldn’t get it out. He ran crying to his mother. His mother couldn’t get the paper out, either. A week later, the paper was still in the boy’s nose. His nose began to have a bad smell.
So his mother took the boy to a hospital. The doctor looked up at the child’s nose, but she couldn’t get the paper out. She said she had to cut the boy’s nose to get the paper out.
The boy’s mother came home looking sad. She didn’t want her child to have his nose cut. The next day she took the boy to her friend Sidney who lived in a house with an old lady called May. May wanted to see the child, so the child let her look up his nose.
“Yes, I can see it,” May said. “It will be out soon.”
As she spoke, she shook some black pepper on the child’s nose. The child gave a mighty sneeze and the paper flew out. His mother was surprised. May told his mother to take the boy to the seaside for a swim, for the salt water would go up his nose and stop the bad smell.

The clock struck eleven at night. The whole house was quiet. Everyone was in bed except me. Under the strong light, I looked sadly before me at a huge pile of that troublesome stuff they call “books”.
I was going to have my examination the next day. “When can I go to bed?” I asked myself. I didn’t answer. In fact I dared not.
The clock struck twelve. “Oh, dear!” I cried. “Ten more books to read before I can go to bed!” We pupils are the most wretched creatures in the world. Dad does not agree with me on this. He did not have to work so hard when he was a boy.
The clock struck one. I was quite desperate now. I forgot all I had learned. I was too tired to go on. I did the only thing I could. I prayed, “Oh God, please help me pass the exam tomorrow. I do promise to work hard afterwards, Amen.” My eyes were so heavy that I could hardly open them. A few minutes later, with my head on the desk, I fell asleep. The underlined word “wretched” in Paragraph 3 probably means ____________.

We live in a digital world now, and a student’s technology needs have changed. For the early years, when you are in primary school, you can get by with no technology at all. Even if you have a computer, it’s a good idea to get children familiar with libraries. At this age, trips to the library are like family outings.
As you get closer to middle school, a computer with Internet access becomes more of a necessity. Teachers will often give assignments that require a student to use the Internet for research. After a computer, technology choices for students become more difficult to make – especially when it comes to cell-phones. Kids will beg their parents for a cell-phone, especially in middle school. For many parents, it’s a safety issue: They want to know that their kids can reach them quickly if necessary. For teachers, cell phones can be used to record lessons when students are absent. But many teachers dislike cell-phones. Some kids send messages or have talks in the class. Sending messages also raises the problem of cheating on exams. More and more schools are now forbidding the use of cell-phones.
Many kids see iPods as necessary things to have. IPods are great for music, but do they do anything good for your children’s education? Maybe they do. That’s the opinion of Doug Johnson, an educator for 30 years. Johnson says that educators should accept all new forms of technology in the classroom, including iPods. “Some do more with their cell- phones than we can do with our laptops,” he jokes. “I don’t think we should be afraid. The truth is that it’s easier to change the way we teach than to change the technology habits of an entire generation.” According to author, primary school children should___.
| A．use the computer and the Internet regularly |
| B．ask their parents to buy them cell-phones |
| C．buy iPods to listen to music |
| D．go to libraries to read more books |
Why do parents agree to buy their children cell-phones?
| A．They want their children to be cool. |
| B．They think cell-phones be helpful to their study. |
| C．They want to keep in touch with their children. |
| D．They want their children to keep up to date. |
The following are all reasons why many teachers dislike cell-phones EXCEPT ____.
| A．cell-phones can be used to cheat on exams |
| B．schoolchildren will send messages during class |
| C．cell-phones can be used to record lessons |
| D．schoolchildren might talk on them during class |
What does the underlined word “that” refers to?
| A．iPods can be used to listen to music. |
| B．iPods can be helpful for children’s education. |
| C．iPods can be used to play games. |
| D．iPods are necessary for children’s lives. |
We can infer from what Doug Johnson said that _____.
| A．cell-phones are not useful to students |
| B．teachers should let students use cell-phones |
| C．it’s better for teachers to change their teaching methods |
| D．schoolchildren should follow the trends(潮流) of fashion |
