A fish that lives in America can live out. of water for months at a time, similar to how animals got used to land millions of years ago, a new study shows.
The Mangrove Rivulus, a kind of little fish, lives in small pools of water. When their living place dries up, they live. on the land, said Scott Taylor, a researcher in Florida.
The fish can grow as large as three inches. They group together and breathe air through their skin before they can find water again.
The new scientific discovery came during a trip.
"We were travelling for fun. and one day I kicked over a log (圆木) and the fish came out," Taylor told reporters by telephone. He said he would make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish(肺鱼) found in Australia, Africa and South America can live out of water, but only in a not active(活波的)way. But no other known fish can be out of water as long as the Mangrove Rivulus and keep active, according to Patricia Wright, a biologist at a Canadian University.
More studies of the fish may tell how animals changed over time.
"These animals live in conditions similar to those millions of years ago, when animals began to move from water onto land," Wright said.The Mangrove Rivulus is a type of fish that_________.
| A．lives on land in Africa |

The population of the world is increasing rapidly. By 2020, there could be 7.5 billion people on the earth. Will there be enough food for all these people? Some scientists think fish farming might solve this problem. However, other scientists worry that fish farming could bring serious environmental problems.
Fish farming is not a new thing. There were fish farms in China 3,000 years ago. Today, about one third of the fish we eat comes from fish farms.
Most fish farms raise plant-eating fish. Popular kinds of plant-eating fish are carp, tilapia, and catfish. However, many fish farms are starting to raise meat-eating fish. A popular type of meat-eating fish is salmon. However, it takes up to 5 tons of wild fish to produce just 1 ton of farm-raised salmon. So if this continued, many types of wild fish could become extinct.
Critics (评论家) of fish farming also say that farm-raised fish is unhealthy. They say there are dangerous chemicals (化学物质) in the fish. They also say fish farming pollutes the water. Some people say that the ways of farming being used now won’t produce enough fish anyway. Instead of building fish farms in lakes or near the coast, they say that the fish farms could be moved far out into the ocean. In the future, fish farms might be large cages that move to the ocean.Which of the following about fish farming is true?
| A．It is very popular around the world. |
| B．It is a new thing in 2010. |
| C．It appeared in China about thirty centuries ago. |
| D．It can solve the problem of the world’s population. |
_________ is not a kind of plant-eating fish.
| A．Carp | B．Catfish |
| C．Tilapia | D．Salmon |
What does the underlined word “extinct” mean?
| A．绝种的 | B．无家可归的 |
| C．弱小的 | D．惊慌失措的 |
How many reasons do the critics hold against the fish farming?
| A．2. | B．3. | C．4. | D．5. |
What’s the passage mainly about?
| A．One way to control the growth of population. |
| B．One way to feed more people. |
| C．One way to catch more fish. |
| D．One way to save the wild fish. |
Every year several thousand people die in the car accidents in Great Britain. And between one and two hundred thousand people are hurt.
There are rules to make the roads safe, but people do not always obey (遵守) the rules. They are careless. If everybody obeys the rules, the road will be much safer. How can we make the roads safer?
Remember this rule. In Great Britain traffic keeps to the left. Cars, buses and bikes must all keep to the left side of the road. In most other countries traffic keeps to the right.
Before crossing the road, we should stop and look at both ways. Look right and left. Then, if you are sure that the road is clear, it is safe to cross the road. If you see small children or very old people, help them to cross the road. We must teach our children to cross the road safely. We must always give them a good example. Small children must not play in the street. If we want to make the roads safer, _______.
| A．everybody must be careful and obey the traffic rules |
| B．traffic should keep to the right |
| C．don’t cross the road too often |

| A．Before crossing the road, we should stop and look at both ways. |
| B．In our country traffic keeps to the right. |
| C．Few people die in the traffic accidents in Great Britain |
