Sharks use their good sense of smell to search for prey（猎物）. But a new study shows that the rising levels of carbon dioxide in the ocean could reduce sharks' ability to find food. It's bad news for a healthy ocean. Sharks are top predators（掠食动物）and are like the ocean's weed controllers.

Dixson works at the Woods Hole Oceanographic Institution in Massachusetts. Her earlier work has shown that clown fish in acidifying（酸化的）water act strangely. "We want to expand this research to sharks .because we know how important it is for sharks to find their food through their sense of smell," said Dixson.

Her team started by placing sharks in each of three different pools for five days. Each pool had a different level of carbon dioxide in it. The first had the same amount as today's ocean water. The second had a level of carbon dioxide that scientists expect to reach by 2050. The third pool had the highest level of carbon dioxide that could develop by the year 2100.

Sharks weren't allowed to eat any food while in the pools. This made sure that they would be hungry. Then, Dixson released the sharks one at a time into a pool with two side-by-side streams of flowing water. In one stream, the researchers pumped water, in which a dead squid had been overnight. This water smelled strongly of the squid. The other stream contained ocean water with no scent（气味）. Because each stream flowed at the same rate and in the same direction, the squid smell stayed in its stream. The sharks could choose to swim in either stream.

Sharks that had been swimming for five days in pools of regular ocean water spent more than 60 percent of their time in the squid-scented stream. The same was true for sharks that had been in water with the carbon dioxide level that could develop by the year 2050. But sharks exposed to the highest level of carbon dioxide spent just 15 percent of their time in the squid-scented stream.

1.Why did the writer mention the sharks smell at the beginning of the passage?

A. Because the writer appreciates their ability to find food.

B. Because the writer considers them dangerous to human beings.

C. Because the writer intends to show how to control weed in the ocean.

D. Because the writer worries about the sharks in the ocean.

2.What is Paragraph 3 mainly about?

A. What the ocean in the future will be like.

B. Who helped Dixson conduct the study.

C. What kinds of pools were used during the study.

D. What the levels of carbon dioxide will be at in the ocean in the future.

3.The researchers pumped water where a dead squid had been overnight to ______.

A. help the sharks look for food

B. test the sharks' sense of smell

C. prove that sharks like eating squids

D. explain why carbon dioxide in the ocean affects sharks

4.What does the underlined sentence in the last paragraph suggest?

A. Sharks like the squid-scented stream better.

B. Sharks like the stream with the high level of carbon dioxide.

C. Sharks spent 15% of their time in the squid-scented stream.

D. The high level of carbon dioxide can affect the sharks ability to smell.

A person’s nose is important for breathing and smelling, while the ears have the basic functions of listening. They are both used in many popular expressions.

1. But the following passage is not to discuss facial features, but to explain how they are used in many popular expressions.

Some people are able to lead other people by the nose. For example, if a wife leads her husband by the nose, she makes him do whatever she wants him to do.

Some people are said to be hard-nosed. 2. If someone is hard-nosed, chances are he will never pay through the nose, or pay too much money, for an object or service.

It is always helpful when people keep their nose out of other people’s business. They do not interfere (干涉). The opposite of this is someone who noses around all the time. This kind of person is interested in other people’s private matters. 3.

Someone who keeps his nose to the grindstone (磨刀石) works very hard. This can help a worker keep his nose clean or stay out of trouble.

One unusual expression is that it is no skin off my nose. This means that a situation does not affect or concern me. 4. That is, he makes a situation worse for himself by doing something foolish because he is angry.

What about ears? Well, I hope you are all ears or very interested in hearing more expressions. We might even put a bug in your ear or give you an idea about something. 5. This means to be interested in what is happening around you and what people are thinking.

If you are a good person, you will lend an ear to your friends. You will listen to them when they have a problem they need to talk about. Sometimes we are supposed to play it by ear, which means to decide what to do at the last minute instead of making detailed plans.

A.He is considered nosey.

B.Our last expression is to play it by ear.

C.I think we have explained the nose expressions.

D.We also advise you to keep your ear to the ground.

E.Nose and ears are among the most important sense organs.

Nowadays, the term " sense of happiness" has been repeatedly mentioned in various medias.

The survey aroused a heated discussion across the country and people from all walks of life expressed their opinions.

" I would say I'm pretty happy at present because my dear daughter has graduated from college and found herself a good job. " said a woman in her fifties with a big smile on her face.

Though it seemed that most people said they were happy, different voices were still heard and should not be ignored. There was a migrant worker(农民工) whose answer to the question was widely spread online. When asked if he was happy, he said " My family name is Zeng", showing his determination to refuse the interview as well as his annoyance to mention happiness.
