Some scientists say that animals in the ocean are increasingly threatened(威胁) by noise pollution caused by human beings. The noise that affects(影响)sea animals comes from a number of human activities. 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(测量)on land. A noise of one hundred and twenty decibels on land caused pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have planned to set a noise limit of one hundred and twenty decibels in oceans. They have found that noises at that level can frighten and confuse(混淆) whales.
A team of American and Canadian scientists discovered that loud noises can seriously hurt 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 disagree to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial(工业的)and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect(怀疑) that noise is a greater danger than they believed. They want to stop noises from harming creatures in the ocean.
According to the passage, which of the following is increasingly dangerous to sea animals?

A.The man-made noises. B.The noises made by themselves.
C.The sound of earthquakes. D.The sound of the ice-breaking.

Which of the following is discussed in the second paragraph(段落)?

A.They are deaf because of noises.
B.Noises at a certain level may hurt them.
C.They are easily confused by noises.
D.Noises will limit their ability to reproduce.

We can know from the passage that many scientists think that the noise limit(限制) of one hundred twenty decibels would __________.

A.stop them from doing their research work
B.benefit them a lot in their research work
C.do good to their health
D.increase the industrial output(产量)

The father’s role in the family is important. One researcher says babies who are cared for by their fathers have greater cognitive (认知的) development at one year of age than babies not cared for by their fathers. Another researcher reports that by spending time with their pre-school children, fathers can help to develop children’s language ability. Researchers also point out that for school-age children, fathers are one bridge with the outside world.
Fathers who value (重视) education have children who do better in school than those children whose fathers don’t value education. What’s more, fathers who spend quality time with their children may give their children happy memories which may last a lifetime.
While each father is a unique person who educates children in his own style, good fathers have something in common.

注意:每个空格只填一个单词
People visit other countries for many purposes. Some travel on businesses; others travel to visit interesting places that are only found in other countries.
Wherever you go, and for whatever purpose, it’s important to be safe. A tourist can attract a lot of attention from local people. While most people you meet when travelling are sure to be nice, there are dangers—theft being the most common. So prepare for your trip in advance.
As you prepare for your trip, make sure you have the right paperwork. You don’t want to get to your destination (目的地)only to find you have the wrong visa, or worse, that your passport is about to expire (到期). Also, make sure you travel with proper medical insurance, so that if you are sick or injured during your travels, you can be treated. If you want to drive while you are abroad, make sure you have an international driver’s license.
If you need to take medicine with you—such as travel-sickness pills—keep it in its original container(容器). If you don’t, you may find yourself doing a lot of explaining to customs officials at your destination.
Buy a guidebook and read about the local customs of the country you are going to. Also, try and learn a few basic words and phrases—don’t assume that the local people will speak your language.
When you get to your destination, you’d better use official transport. Always go to the bus and taxi stands, don’t accept rides from strangers who offer you a lift. If there is no meter in the taxi, agree on a price before you get in. If you prefer to stay in cheap hotels while travelling, make sure you can lock the door of your room from the inside. If you are travelling with valuables such as jewelry, or a lot of money, you should ask about a safe for storing them in. Finally, remember to smile. It’s the friendliest and most sincere form of communication, and is sure to be understood in any part of the world!
