It is predicted that there will be five scientific breakthroughs in the 21st century.
We’ll know where we came from. Why does the universe exist? To put it another way why is there something instead of nothing? Since the 1920s, scientists have known the universe is expanding, which means it must have started at a definite time in the past. They even have developed theories that give a detailed picture of the evolution of the universe.
We’ll crack(破译)the genetic code and conquer cancer. Thanks to 20th century antibiotics(抗生素), the once dreaded, once incurable disease now can mean nothing more serious than taking some pills. As scientists learn more a-bout the genetic code and the way cells work, many serious diseases —cancer, for one—will become less threatening. Using manufactured "therapeutic"(治疗的)viruses, doctors will be able to replace cancer-causing damaged DNA with healthy genes.
We’ll live longer(120 years?). If the normal aging process is basically an invisible contest in our cells—a contest between damage to our DNA and our cells’ ability to repair that damage—then 21st century progress in genetic medicine may let us control and even reverse the process.
We’ll manage Earth. In the 21st century, we’ll stop talking about the weather but will do something about it. We’ll gradually learn how to predict the effects of human activity on the Earth, its climate and its ecosystems. And with that knowledge will come an increasing willingness to use it to manage the workings of our planet.
We’ll have a brain "road map". This is the real "final frontier" of the 21st century. The brain is the most complex system we know. It contains about 100 billion neurons, each connected to as many as 1, 000 others.
Which of the following is NOT one of the breakthroughs in the 21st century?
选项
A、The time when the universe came into existence will be known.
B、The life span of human beings will increase.
C、People will have a better understanding about the brain.
D、People will manage the space.
