Technology has become so advanced that the previously impossible seems to occur on a daily basis. And yet — we still have no cure for the common cold.

According to Peter Barlow, a scientist at Edinburgh Napier University in the UK, the main challenge lies in the many different types of cold viruses. There are at least 160 types. They changed so easily that they quickly become resistant to drugs, or learn to hide from our immune systems. In other words, a single cure isn’t likely to work on every type of cold.

However, researchers from Stanford University have found a possible answer. They discovered a protein that the viruses need. Without it, they can’t spread inside your body. To　 identify the gene(基因) which produces the specific protein needed by the viruses, researchers used a gene-editing technique to test all genes. These modified (改变的) cells were then exposed to a range of viruses, including ones causing the common cold. All the viruses were unable to replicate (复制) inside cells without a gene that produces that specific protein.

Then, they tested genetically modified mice, which were completely unable to produce the protein. The mice were able to live normal lives without the protein. “Lacking that gene protected the mice completely from viral infection,” associate professor Jan Carette, from Stanford, told the BBC. “These mice would always die, but they lived through and we saw a very strong reduction in copying viruses and very strong protection. We have identified a fantastic target that all cold viruses require and depend on. Take that away and the virus really has no chance. ”

Carette said the plan is to find a drug which can temporarily control the protein, instead of producing genetically modified humans.

1.Which of the following can best describe common cold viruses?

A.Severe and deadly. B.Mysterious and stubborn.

C.Diverse and changeable. D.Challenging and oversized.

2.How does the protein work?

A.Help viruses spread. B.Reduce physical infection.

C.Fight against other viruses. D.Strengthen the immune system.

3.What can we learn about the genetically modified mice?

A.They caught cold easily. B.Their health worsened.

C.They produced more protein. D.They were able to survive,

4.What is purpose of the research?

A.To control certain genes. B.To conquer the common cold.

C.To test a new drug. D.To cure genetically modified mice.

Science and technology have advanced at such a rate that cloning has now become a reality. The possibility of cloning humans is a serious issue(争论点) and raises ethical(伦理的) questions. In my opinion, cloning is useful for research into cures for disease. However, I think that it needs to be approached with caution and carefully monitored by governments.

Research into cloning and stem(严格的) cell production is primarily aimed at finding new treatments for currently incurable illnesses. While this would improve the quality of life for many, not enough is understood about what effects cloning would have on the world in the future. This is primarily because we do not understand enough about the results of cloning and both the physical and psychological effects that it is likely to have on cloned humans and on the rest of the world. Furthermore, it is thought that a cloned human would be unlikely to survive birth and would suffer from complications(并发症) resulting from malformed(畸形) organs .

There are also serious ethical issues in danger. In essence(在本质上), those who are against cloning would argue that scientists have no right to play God and to interfere(干扰)with natural processes. Producing embryos for the purpose of harvesting stem cells for research presents important questions about the nature and status of the embryo being produced. It may also make us question whether throwing it away after use reduces the value we place on human life.

In conclusion, I do not agree that research into cloning using human embryos should continue. This is not only because it may reduce the value we place on human life, but also because not enough is known about the effects.　　 However, I do think that if there is a way to produce stem cells using cloning which does not put human life at risk, then governments should continue to support it.

1.What is the writer’s general opinion on cloning?

A. It is useful in every area of research.

B. It needs to be carefully controlled by governments.

C. It is useful for research into cures for disease if it is controlled.

D. It is only useful for research into cures for disease.

2.The underlined word “approach” in the first paragraph means “______”

A. reach a high level or amount　　 B. move forward

C. come near　　 D. deal with

3.The writer’s main reason against cloning is that ______.

A. not enough is known about the effects of cloning

B. a cloned human would be likely to die of malformed organs

C. cloning has negative physical and psychological effects on clones

D. it would affect the quality of life for many

4.In the last paragraph, the writer thinks governments should______

A. not put human life at risk

B. support all forms of research into stern cell production

C. not support any form of research into stern cell production

D. support research into stern cell production harmless to humans life

Science is always advancing over time. A self-driving car from the Google may be coming to a street near you. However, you won’t be able to buy it now. “We’re working to build the world’s most experienced driver,” Kraft, director of the project, said. “Everything that we learn in one of our cars gets passed to all of our cars. But you may need to get over the idea of traditional car ownership along the way.”

Google’s software has already driven 5 million miles in U.S. cities, including an “early rider” test in Phoenix last April. Since then Google has grown confident enough to remove the “auxiliary wheel”: a human “safety driver”. Powering the vehicle’s self-driving functions is a series of cameras, radars and sensors on the car’s roof, which detect everything nearby from other vehicles and passers-by to cyclists.

Kraft stressed that Google’s cars aren’t connected—they don’t need a 5G wireless link to go anywhere. “The car has everything it needs to drive on the car itself.” He said, “There are no signals coming from outer space or something telling it to turn right.” The resulting ride may not be too exciting but safe. Kraft added. “We can see three football fields down the road, we would come to a stop before we ran into these crowds.”

Google’s system has a major advantage over the semi-autonomous（半自主的）systems of Tesla and Cadillac, both of which need continued human attention. Kraft said Google plans to have service in every major city by 2028 with thousands of cars driving themselves.

1.What does the underlined words “auxiliary wheels” in Paragraph 2 refer to?

A. A car that is very old.

B. A driver who has been trained well.

C. A part of a car used to sound the alarm.

D. A condition where a driver doesn’t know his role.

2.Why is Google’s car thought to be safe in the text?

A. Because it can get away from danger easily.

B. Because it is equipped with 5G wireless link.

C. Because it can stop before the crowds occasionally.

D. Because it can keep a safe distance from everything nearby.

3.What can we learn from the text?

A. Google’s software has not been tested.

B. Google’s cars have not been put into the market.

C. Driving the Google’s car may not be too exciting.

D. Google’s cars still need driver’s attention all the way.

4.What does the author think of the Google’s car?

A. It’s affordable.

B. It’s still a theory.

C. It has a bright future.

D. It’s the most advanced by now.

高二英语单项填空中等难度题查看答案及解析

We live in a time when technology has enabled everyone to be a journalist. Yet not everyone has the proper training. Whether out of ignorance or out of a sense of honor, some of the journalism online has done a better job of changing public opinion than showing the whole truth.

Two recent stories are perfect reminders of the difference between the urge to change minds and basic journalism ethics(道德标准).

“A college kid took some birds from a nearby tree and was sentenced to 10 years in prison,” went a recent online headline from the Chinese Internet. The accompanying vote showed that 85 percent of respondents sided with the student. Some joked that most boys would be guilty of such a crime because everyone had stolen birds when they were children.

Left out of the original report was the fact that the birds in question were falcons, which are on the nation’s list of protected, endangered species. Birdwatchers also said that it was unlikely Yan Xiaotian, the 21-year-old defendant, had found the 12 birds in one tree. For this particular species, he had to search a much larger area.

For me, the most important questions are: Did he know it was illegal before he took the birds and did he know that before he sold them?

Follow-up reporting has found that the evidence showed that Yan knew what he was doing. The only point of uncertainty is the very first time he took the first birds when he could be unaware of their status and value. As a matter of fact, the prosecutor(公诉人) started out asking for a light punishment, but took a U-turn when data from Yan’s cellphone clearly showed that he had stolen them.

The punishment, while sounding harsh, followed the law almost to the letter. The court has since said it would review the case, a sign of giving in to public pressure.

Let’s look at the second story, which can be read as either “Elderly man had to walk in his shorts for hours in Sanya after his bike was taken by the city’s quasi-police”(城管) or “Retired official illegally parked his bike for a swim and made the city apologize and fire a low-paid city management staff member”.

Both played up(渲染) different parts of the same story. For me, Bi Guochang’s age and former official title are not relevant to the case. The key is whether he indeed parked his bike illegally and whether proper procedures were being followed by taking it away and making him get it back. Yet the reports focused on the image of an old man walking only in his shorts. He could have phoned his family for backup or taken a taxi home first before complaining, as most would do in that situation.

Such stories read like badly-written morality tales, with everything in black and white and a simple yes-or-no message. Real life is much more complicated. Reporters have to be neutral and avoid taking sides too early.
