1 . Modern humans have only existed for a relatively short time, and maybe we’d like to stick around a lot longer. But how can we do that?
Figure out climate change.
Figure out nuclear weapons.
A single nuclear weapon doesn’t pose a threat to all of humanity, but the thousands of them in the world right now certainly do.
Figure out asteroids(小行星).
If you want to know the terrible consequences for ignoring space borne threats, just ask the dinosaurs how well it worked out for them. Asteroids have the ability to cause massive extinction events, wiping out vast numbers of entire species.
| A．The consequences can’t be avoided. |
| B．Countries are joining hands to solve it. |
| C．Now the chances of one nuclear explosion increase. |
| D．The earth’s climate has changed for millions of years. |
| E．While these kinds of events are rare, the risks are severe. |
| F．And we can see the effects of climate change everywhere. |
| G．We need to disarm as much as possible to reduce the risk of disaster. |

3 . You cannot judge a book by looking at its cover! That's what a group of parents and students in Hangzhou has found out this term.
When they came to school in September, the students were shocked to learn that their class teacher was to be a P.E. teacher. How could someone who teaches table tennis and basketball know anything about academics? Their parents were equally worried and pressured the school to replace ''Miss Muscle'' with a ''Miss Brain. '' However, the principal(校长) did not give in to the pressure and now the parents and students are happy that the school firmly insisted.
After three months, the P.E. teacher, whose name is actually Miss Su, has turned out to be a wonderful class teacher. She is intelligent, kind and helpful. She is a good leader who keeps her students active in their studies and participate in school activities. And she has won the parents over with her real caring for their children. In other words, Miss Su, the P. E. teacher, is ''pretty extraordinary. ''
The early negative reaction against Miss Su is an example of bias(偏见). A ''bias'' is wrong in thinking that has an influence on a person's opinions and decisions. For example, in business, tall men are more likely to be bosses. In the United States, anyone who is above 190 centimeters tall can expect to have a higher salary and to get more promotions than his shorter co-workers. Similarly, women have a difficult time climbing the career ladder because their bosses(mostly men!) think that women lack leadership skills and the necessary toughness to make difficult decisions. Neither of these opinions is based on facts or the talents of the individual. They're just bias.
