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.

D
Almost everyone has dropped some food on the floor and still wanted to eat it.If someone saw you drop it, he or she might have shouted, “ 5-second rule!” This so–called rule says food is OK to eat if you pick it up in five seconds or less.But is that true?
Professor Anthony Hilton from Ashton University, UK, tested the rule with his students.They found that food dropped for five seconds is less likely to contain bacteria(细菌) than if it sits there for longer.
For the study, Hilton and his students tested a lot of foods——bread, pasta, cookies and candy—to see how much bacteria they had when they made contact with the floor.They allowed the food to lie on the different types of flooring—carpet(地毯), laminate (复合地板) and tile(瓷砖) — for three seconds to 30 seconds.
Not surprisingly, the longer the food was on the floor, the more bacteria it had.And the type of floor where the dropped food landed had an effect.Bacteria are least likely to transfer(转移) from carpet, while they are most likely to transfer laminate or tiled surface after more than five seconds.
The study also found that the wetter the food, the more likely it was to pick up bacteria.Although most people are happy to follow the 5-second rule, eating food dropped on the floor still carries an infection(感染) risk.“It very much depends on which bacteria are on the floor at the time.” Hilton told Forbes.
What is the “5-second rule’ mean?

A.People often shout at someone when they drop food on the floor.
B.Food is safe when you pick it up off the floor in less than five seconds.
C.It’s better to eat dropped food when it’s been on the floor for over five seconds.
D.Food will go bad when dropped food on the floor in five seconds or less.

Where is Ashton University?
A.In the USA.
B.In England.
C.In China.
D.In France.
Hilton’s test wanted to find out____________.

A.if the “5-second rule” is true
B.the students’ favorite food
C.which food is easily dropped
D.if different types of floor have different bacteria

According to the test, we learn the following EXCEPT ________.

A.the dropped food had more bacteria if it sat on the floor for longer.
B.the dropped food on the carpet had the least bacteria.
C.bacteria was impossible to transfer from laminate or tiled surfaces.
D.the wetter food was likely to pick up bacteria.

According to the article, the infection risk of the dropped does NOT depend on _____________.

A.how long the food sits on the floor
B.what the dropped food is

One day a man found a cocoon(蚕) of a butterfly in the forest.He sat there for several hours and watched the butterfly.Suddenly, a small opening appeared and the butterfly made its great effort(努力) to force its body through that little hole.Then it seemed to stop making any progress.It appeared as if it had gotten as far as it could and it could go no further.(那个蛹好象忘记了它该怎样做, 也好象停止了挣扎).
So the man decided to help the butterfly.He cut off the remaining bit of the cocoon so that the butterfly would come out easily.But to his surprise, the butterfly got a heavy body and very small wings when it came out of the cocoon.
The man continued to watch the butterfly because he expected that the body would grow smaller at any moment and the wings would become larger and be able to fly.But neither happened! In fact, the butterfly spent the rest of its life crawling(爬) around with a heavy body and small wings.It was never able to fly.
The man was in his kindness, but he didn’t understand the nature rules.Before the butterfly came out of the cocoon, fluid(液体) from its body must be forced into its wings, and then would be ready for flying.It must have a hard struggle(拼搏) to get through the small opening to get its freedom from the cocoon.
Sometimes struggles are exactly what we need in our life.If God allowed us to go through our life without any difficulties, it would make us fail.We would not be as strong as we could have been, we could never fly.

A.It was trying to make a cocoon for it self.
