Bacterial Quorum Sensing
Bacteria(细菌)play an important role in our lives. They can keep us alive as well as make us sick. It wasn’t until fairly recently that we learned bacteria can communicate with one another.
In the 1960s, researchers found that a kind of bacteria called Vibrio fischeri（费氏弧菌） produced no light when they were alone, but that they exhibited great amount of light as the bacterial population grew to a certain number. How did this happen? How can Vibrio fischeri tell the difference between times when they’re alone and times when they’re in a community, and then all do something together?
Researchers found they talk to each other with a chemical language—signal molecules(信号分子). Vibrio fischeri makes signal molecules, and it also has a receptor on its surface that fits like a lock and key with a signal molecule. As the bacteria increase, more and more signal molecules are sent into the environment. When signal molecules increase to a certain amount, they lock down into those receptors and information comes into the bacteria, which tells them how many neighbors there are. As soon as they realize the population has hit the certain number, all of the bacteria behave as a group, making light together. In the past ten years, researchers have found all bacteria have systems like this: they make and recognize chemical words, determine(判断)the size of the community, and carry out tasks that would be unsuccessful if a single one were to act alone. This process is called quorum sensing.
Most of the time, bacteria live with thousands of other species (种类)of bacteria. There has to be a language of interspecies communication. In fact, bacteria have another kind of signal molecule, which is the common language used by all species. Moreover, this kind of molecule has its own receptor. In this way, bacteria are able to count different populations, and then they decide what task to carry out depending on which species has the greatest population.
Knowing how bacteria communicate could influence how we fight disease. What if bacteria can’t talk or hear? They won’t recognize when there are enough bacteria and when to exhibit the group behavior to make us sick. Researchers are developing a method—to make molecules that look like the real ones and then they lock into the receptors to jam recognition of the real situation.
On the other hand, researchers also improve the conversation of the beneficial bacteria, so they can do things that we want them to do better than they would do on their own.
1.According to the passage, what can we learn about quorum sensing?
A.Quorum sensing may happen when there is only one Vibrio fischeri.
B.Signal molecules are kept away from receptors during quorum sensing.
C.Most bacteria have similar systems to make light during quorum sensing.
D.Bacteria carry out a group task when their population hit a certain number.
2.What can we learn from the passage?
A.The more species there are, the more group actions bacteria will take.
B.In different environments, bacteria have different interspecies languages.
C.Beneficial bacteria communicate better by themselves than harmful ones.
D.To fight disease, researchers try to turn off the communication between harmful bacteria.
3.The passage is mainly about ________.
A.why bacterial population grows B.how bacteria communicate with each other
C.which bacteria help fight disease D.what scientists do to find quorum sensing

Stamps help connect us with others. They have played an important role in people's lives for a long time.
Stamps pay for a letter to get where it needs to be. When there were no stamps, people did not pay for the letters they sent, but instead they paid for the letters they received. The first stamp ever made is called Penny Black. It is a British stamp made in 1840 with a picture of Queen Victoria on it. The number of people who send letters and use stamps has gone down. But stamp collection is still one of the world' s most popular hobbies. There are even stamp clubs to help people find new stamps to add to their collections. Interestingly enough, the Internet may have reduced the need for stamps, but it is actually helping collectors find more stamps to add to their collections.
任务5: 根据短文（C）内容完成表格,每空一词
| Stamps Help Us Keep in 1. with Other | |
| The first stamp | Made in 2.in 1840 |
