五、阅读理解
20．
Today there are nearly 7. 4 billion people on Earth. By the year 2050 there may be 9. 8 billion. There are many people to feed. We need more and more food.
One way to produce more food is growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic (基因的) material. Foods from plants grown in this way are called genetically modified (转基因的) foods, or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. Scientists make plants which are strong against plant diseases. They can also help in our diseases: a kind of rice will be grown, for example, which stops people becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them because they are unnatural. They may feed people, then hurt them or their children later. But both rich and poor countries are interested in their uses, and they are not going to go away. In 2050, we may think differently about them.
（1）There may be ___________billion people by the year 2050 on Earth.
A．6.4 B．9.8 C．18.5 D．20.5
（2）How have scientists been able to change plants more quickly
A．By making the best plants.
B．By asking the farmers to grow plants.
C．By changing planting environment.
D．By changing their genetic material.
（3）Why do rich countries produce GM foods
A．Because they are easy to grow and bring in more money.
B．Because they are easy to grow and very cheap.
C．Because they help produce more food.
D．Because they are the best plants.
（4）Which of the following is NOT true according to the passage
A．GM plants are not natural.
B．GM plants are strong against plant diseases.
C．Everyone knows how good or bad GM plants are.
D．GM foods may hurt people or their children later.
（5）What can we learn from the passage
A．GM foods will disappear one day in the future.
B．GM foods will not disappear in the future.
C．People will not be interested in GM foods.
D．People will have to stop eating GM foods.
