[1] To ensure the protection of our global village from pollution for us and for future generations, it is the duty of everybody to take an active part in environmental protection.

[2] They have often heard that there are dangerous levels of air pollution in big cities of the world. Yet little has been done to solve this problem. Researchers are telling us that it will certainly cost money to make there polluted cities clean. if not, people will suffer from a lot of serious diseases.

[3] As a result of continued pollution, it is sure that people have to pay more money in health care in the future. Then, cleaning up our water and protecting our food supply will cost us too much. Scientists are trying to inform us that in the future, they will save money and our natural resources by ___________________ now.

[4] It seems to me that people should pay more attention to the environment. The potential damage to the environment should be thought first. In particular, it is for those economists in governments to take the costs of harming the environment into consideration. Once they do that, it will be clearer to everyone that it will pay to change the way they currently go about functioning in society.

[5] Thanks to technologies, especially. clean technologies, a lot less pollution could be produced. It is just a matter of cost. And it will be very important that the developed countries not only just give old and useless technologies to the developing ones.

Every electronic gadget (小玩意) needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts.

Now, scientists in California say they have come up with a way to turn a living cell into a memory device.

It can store only one tiny bit of information, but it’s a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease.

Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can’t be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream.

If normal machines won’t do the trick, perhaps biology will. Scientists who work in the field of synthetic (合成的) biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information.

This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive.

In the new experiment, the researchers turned DNA from bacteria(细菌) into a switch. They “flip (翻转)” a small section of DNA. Then, using the same procedure (过程) , the scientists flip the section again—returning it into its normal structure.

Using these DNA switches, “We can write and erase DNA in a living cell,” bioengineer, Jerome Bonnet, explained to Science News.

It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory—less than what a computer uses to remember a single letter.

 “This was an important proof that it was doable,” Bonnet told Science News. “Now we want to build a more complex system, something that other people can use.”

1.What is the aim of listing the electronic things in the first paragraph?

A. To make the passage more fashionable.

B. To show how electronic things have memory.

C. To discuss things in detail.

D. To make the subject of the text more understandable.

2.What is possible future benefit of the cell-based gadget for people?

A. To detect disease at the earliest point.

B. To help improve the memory.

C. To help people build a body.

D. To replace many electronic gadgets.

3.What is the object being researched?

A. The cells of bacteria.               

B. The DNA of bacteria.

C. A section of bacteria.              

C. The nucleus of bacteria.

4.What do we know about a flipped section of DNA?

A. It has a very small memory.

B. It can function as a computer.

C. It has one letter in it.   

D. It takes a day to complete it.

　　Roses are red, but they've never been blue. They are actually a lot of colors, but they lack the right pigment genes(色素基因)that would make them blue.

　　But don't worry, if blue is your favorite color, science has the answer. US scientists have said they could make the missing pigment gene in the near future with developments in biotechnology.

　　The scientists were studying how some medicines affect the liver(肝脏) when they found a human protein that fumed things blue during the process. This may be used to create the world's first - known blue rose.

　　Scientists have already turned a cup full of bacteria (细菌) blue with an enzyme (生化酶) taken from a person's liver. They're now trying to put this same human gene into roses. Technology also promises to make sure the roe still smells good. Commercial growing has led to many beautiful but dull- smelling roses. Their colors are varied and they last a long time, but they've little fragrance.

　　Genetic engineers are also trying to get science to fight diseases and insects that affect the world's 120 different rose kinds. These roses are a US $10 billion-a-year business world-wide. The technology may be very useful in gardening, say scientists. “We could try to grow blue cotton, blue anything really. ”said a scientist..

　　So far, though, it hasn't been easy. They have only managed to get a few blue spots into the stems. “ It's not as easy as you may think. It's going to take more work. ”

　　They're not alone, an Australian company was set up in 1986 to develop a blue rose. Researchers have tried to put a “blue” petunia gene into rose`. But they have not had much success so far.
