Problem solving is an important skill in our ...

Problem solving is an important skill in our lives. While each problem requires a different skill to solve it, there are certainly common problem solving techniques that can be used in many situations. First, it’s important to make sure that you have the right opinions about your problems. In other words, you should see problems as challenges and should try to get some joy out of solving them. It’s our problems that force us to grow, and it’s our problems that make our lives interesting.

Once you view them as challenges, you also need to realize that all problems can be solved or at least improved, if you think about them in the right way. This means you should take the time out of your day or your activities to pay attention to your problems and think about them for as long as it takes to find solutions (解决方法). And in this way, you will at least be able to feel that you’re doing something about them, and once you do come up with a plan, you may feel your problems are much more manageable.

When you do start coming up with your plan, there are some things that can help you. For example, writing down your thoughts can often help a lot. Form a mind map and start writing down related (相关的) things. This way you can visualize (形象化) the idea and you may feel as if you have really achieved something.

At the same time, don’t be afraid to ask others for help. In nine out of ten cases a problem involves (涉及) another person, then the problem can be solved or at least improved by talking to that person. If your problem isn’t urgent (紧急的), you can talk to people who have skills or experience, which can help you find solutions.

Sometimes you can try to imagine what you would advise yourself to do if you were another person. Imagine that someone else has your problem, what would the solution that you would tell them be? Sometimes this can help you see what might be stopping you all along. In many cases we actually know what the solution is, but we are just afraid of admitting (承认) it. This is because the solution involves a big change to our lifestyles, or because we are simply afraid of failure (失败). By taking a step back, you can realize what is stopping you, and then you can get it over and move forward.

Managing(管理) money is an important skill for adults. But a group of middle school students in the US have had some early lessons.On Sept 23, eighth-graders from Honey Creek Middle School in Michigan, US, had an eye opening experience called Let’s Get Real. The event aimed to help students use money properly.

“I didn’t know it costs so much money just in a month,” said Douglas Dillon, one of the students. Like other students, Dillon acted as a 28-year-old adult with a job and family. He chose to be an engineer. He could earn $5,000 (30,600 yuan) per month. But after he spent his income on essentials (必需品), including housing, taxes (税), transportation, childcare and entertainment (娱乐活动), he only had $347 left. “I really should spend it carefully and not waste it,” said Dillon.

Meanwhile,Braxton Scamihorn,another student from Honey Creek learned a greater appreciation (感激) for his parents and what it takes to pay the bills. The 14-year-old found that “kids cost a lot of money” when he learned that childcare for three children would cost $900 a month.

“It is just a necessary lesson on problems that the teens are going to face when they are about 28 years old,” said Peggy Murdoch, one of the organizers. They hoped the students learned about real life budget (预算) decisions and had more respect for their parents.

1. The aim of “Let’s Get Real” is to 　　　　　　　　 .

A. Help students have a real experience.

B. Help students enjoy the fun of managing money.

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
