   According to a study published last week in the journal Science,scientists have found a way to change a plant's genes(基因)in order to make it use sunlight more quickly. Someday,the results could increase the amount of food produced around the world.

By changing a plant's genes,the scientists were able to increase leaf growth on plants by 14-20 percent. Specifically,scientists changed the plant's protective(保护的)system. “Normally,this system is activated when a plant gets too much sunlight,”said scientist Krishna Niyogi,co-author of the study. “When the plant senses the light,it gets rid of extra energy and creates more leaves. When the plant is in the shade,the protective system is turned off. But the process is slow.”

Stephen Long is the lead author of the study. He compared a plant's protective system to light-adjusting glasses.“When a person wears the glasses outside during the day,the lenses(镜片)darken and lighten depending on how sunny it is. Plants do the same thing,”he said.“But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food.”

The new study sped up the process. By changing the plant's genes,it's more quickly than normal to turn on and turn off the protective system. As a result,leaf growth on the plants scientists used in the study increased. Leaf growth on two plants increased by 20 percent, while leaf growth on a third plant increased by 14percent. Scientists conducted the study on tobacco plants. But they thought the genetic modification would produce the same results in corn or rice.

【小题1】What does the plant's protective system need to keep activated?
A.Mild shade.B.Leaf growth.
C.Genetic changes.D.Enough sunlight.
【小题2】What does the underlined word“modification”in Paragraph 4mean?
A.Development.B.Decoration.
C.Change.D.Copying.
【小题3】What can we infer from this text?
A.Changing how a plant uses sunlight could mean more food in the future.
B.When the plant is in the shade, its protective system is turned off slowly.
C.Too much sunlight will damage plants' protective system.
D.It is hard for plants to create food without enough sunlight.

How did the sea horse get its name? It's not hard to guess. The top half of this fish looks like a small horse. But looking at the sea horse's tail, you might think "sea monkey" is a better name. Then there's the sea horse's pouch(口袋). "Sea kangaroo" might also be a good name for this fish.
Sea horse live in warm ocean waters all over the world. They keep safe from other fish by hiding in plants and grasses that grow under the sea. They can also change colors to match their surroundings(环境). A sea horse in one place for hours at a time by winding its tail around a plant. It feeds on live food, such as small shrimp(虾). For a fish that doesn't move around much, the sea horse eats a lot-- in just one day, a sea horse can eat 3,000 shrimp!
A sea horse keeps the same mate for its whole life, and it's the male(雄性的) sea horse that gives birth to baby sea horses. How does this happen? Baby sea horse start out as eggs, which come from the female's(雌性的) body. The male carries the eggs in its pouch for about three weeks until they hatch(孵化). Soon after the babies are born, the female gives her mate a new set of eggs.
Sadly, the number of sea horses is becoming smaller. Why is this happening? Some places where sea horses once lived have been filled in to make new land. Also, many sea horses are caught and sold as aquarium(水族馆) fish. This really is not a good idea because most sea horses don't live long in aquarium. The best place for a sea horse is the ocean.
【小题1】The sea horse got its name because of its_______.
A.pouchB.head
C.skinD.tail
【小题2】How does a sea horse keep safe from other fish?

C.It remains still.D.It hides in plants and grasses.
【小题3】We can learn from the text that sea horses_______.
A.like to move aroundB.feed on small sea animals
C.live in cold ocean watersD.change color with the temperature
【小题4】What does a female sea horse do with her eggs?
A.She carries them around.B.She hides them in sea grasses.
C.She puts them in the male's pouch.D.She hatches them.
【小题5】Why is the number of the sea horses becoming smaller?
A.They grow at a very low speed.
B.Their food is becoming less and less.
C.They are killed by people for food.
D.Their homes are being destroyed.
