阅读理解

    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.

 请阅读下面的短文,并从方框里的六个句子中选择五个还原到原文中,使 原文的意思完整、连贯。

A..Have the willingness to change an opinion in the face of better data. 

B.Reading is a good way to stay open-minded.

C.A system can be measured,refined,and optimized.

D.The better we get at writing the better we get at thinking. 

E. Argue with yourself.

There is no quick hack to becoming a critical thinker but there are some habits that one can build to after their character in the right direction.

● Read a lot and read widely

{#blank#}1{#/blank#} Well read people understand that there are different ways to look at a problem and different lenses with which to view the world.

● Don't jump to conclusions

A good critical thinker has built up the habit of not jumping to conclusions especially when there is no data.{#blank#}2{#/blank#}

● Create systems,not goals

For example,creating a system habit that promotes writing every day is more effective than setting the goal of writing an essay a week. {#blank#}3{#/blank#}.A goal only focuses on the outputs.

●{#blank#}4{#/blank#}

Great thinkers routinely and intelligently try to counter their own arguments.They go back and forth until only the most rational and strongest argument exists based on the knowledge they have.

● Write

Writing is thinking. {#blank#}5{#/blank#}.Writing also helps us separate what we actually know from what we think we know.
