Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world？It’s an increasingly urgent question，given the recent highprofile(引人注目的) mining accidents in Sago，W.Va.and Huntington，Utah.A small group of engineers and robotics experts look forward to a day in the nottoodistant future when robots and other technology do most of the dangerous mining work.
Robotic technology，in particular，holds much promise，McAteer says，especially when it comes to mapping mines and rescuing trapped miners—the special operations of the mining industry.
One of the first mining robots was developed five years ago at CarnegieMellon University’s Robotics Institute.It was called Groundhog and it looked like a golf cart.It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business.
The latest design is called Cave Crawler.It’s a bit smaller than Groundhog，and even more advanced.It can take photos and video and has sensors mounted(增加) that can detect the presence of dangerous gases.Incredibly，the robot has a real sense of logic.If it comes across an obstacle it gets confused.It has to think through the process and where to go next，and sometimes it throws_a_fit just like a real person.
The biggest obstacle，though，is cost.The original research project was federally funded，but that money has dried up，and it’s not clear where future funding will come from. Partly for that reason，and partly because of advances in safety，mining is not nearly as dangerous as it was in the past.Since 1990，fatalities(致命性) have declined by 67 percent and injuries by 51 percent，according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry.The robots do the most repetitive and dangerous jobs，but don’t eliminate(消除) the need for human workers.The underlined phrase “throws a fit” in Paragraph 4 probably means “________”．
| A．gets angry | B．gets sick |
| C．becomes hungry | D．becomes cheerful |
We can infer from the last paragraph that ________.
| A．robots in mines will serve much in the automotive industry |
| B．there will be no need for human workers in mines |
| C．the mine robots will have a very bright future |
| D．robots in mines have a long way to go |
Which of the following is TRUE according to the text?
| A．Mining robots do most of the mining work at present. |
| B．Groundhog can discover the presence of dangerous gases. |
| C．Experts are trying to make robots save miners in danger. |
| D．Robots cannot do dangerous work in dark areas. |

Robert was born in a small town in England. His father has a farm and can supply him enough money to finish university where he's studying law. The young man studies hard and hopes to be a famous lawyer.
Last Monday their term was over. Robert said to his father on the telephone that he was going to travel in a small country during his summer holiday.

In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenzalike cases. Influenza is sometimes called “flu”or a “bad cold”. He took samples from the throats of patients in his hospital and was able to find the virus（病毒）of this influenza.
There are three main types of influenza virus. The most important of these are types A and B, each of them having several sub-groups（亚群）. At the hospital the doctor recognized that the outbreak was because of a virus group A, but he did not know the sub-group. He reported the outbreak to the World Health Organization in Geneva. W. H. O. published the important news together with reports of the same kind of outbreak in Hong Kong, where about 15％～20％ of the population had become ill.
As soon as the London doctors received the package of throat samples, they began to test them. They found that they could reproduce themselves at a very high speed. Continuing their careful tests, the doctor checked the effect of medicine used against all the known sub-groups of type A virus. On this virus, none of them was of any use.
Having separated the virus, the two doctors now made tests on some selected seleceted animals. In a short time the usual signs of the disease appeared. These experiments showed that the new virus spread easily, but that it was not a killer. Scientists, like the general public, called it simply “Asian flu”.

Cancer Research UK has launched an online chat forum for cancer patients to swap stories or share experiences on how to cope with such a disastrous disease．
But Cancer Chat is a forum with a difference：it has an information safety net．
This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue “cancer cures’’ or scientifically unreasonable information．
Anyone can have access to the messages posted on Cancer Chat but if people wish to post a message they will need to register．
And Rebekah Gibbs，a cancer patient and star e f TV’S Casualty has voiced her support for the new project．“I think Cancer Chat is a brilliant idea，’’she said．“I have written a public diary about what I went through with breast cancer and I have had such a heart-warming response from other people going through the same thing．
“The idea of a Cancer Chat forum means you can share information about treatment and side effects and you can really open up about your feelings online in a way that can be difficult when talking to close friends and family．And with Cancer Research UK．monitoring the forum people can be guaranteed the quality of information being exchanged．”
Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp UK website which is specially designed to give patients and their families 6,000 pages of up-to-date information that is easy to understand and explains a wide range of treatments for different types of cancer and give details of clinical trials．There is also a UK database of cancer clinical trials．
The award-winning website attracts around one million visitors a month and Cancer Research UK hopes that some of these visitors will also want to post comments on the Cancer Chat forum．
For those who do not have access to computers and have questions about cancer, the charity's team of cancer information nurses are available during office hours to talk over patients’ concerns on the phone．Cancer Chat is quite different from other forums in that ．
| A．it has the support of a famous TV actress |
| B．it is a source of reliable information |
| C．it provides a huge amount of cancer information |
| D．it attracts a great number of visitors from all over the world each month |

When someone steps on your toe by accident, you will hurt plenty．But it hurts even more, if you think the person does the same thing on purpose．Earlier studies have found that the feeling of pain can change with how it is experienced．That is why giving people sugar pills and saying they are medicine can make them feel better．
This study examined whether self-reported pain is indeed higher when the events producing the pain are understood as intentionally caused by another person．For the study, the researchers told 40 volunteers that they were going to do a series of tasks, including color matching, number counting and discomfort assessment．This last task involved their receiving a brief electric shock to the wrist．They were told that a partner, sitting in another room, would choose which task they would do, and a computer screen helped them to know their partner’s choice．
In some cases, the volunteers were told their partner had chosen the pain tolerance test．In others, they were told the computers would select the pain tolerance test regardless of their partner’s choice．When volunteers thought that their partners were making the shocks on them on purpose, the feeling made the pain worse．As a matter of fact, they were the same．
This study provides evidence that the experience of pain changes depending upon how they think when people have been harmed．Specifically, the meaning of a harm — whether it was intended — influences the amount of pain it causes．So, although a broken toe may hurt, an intentionally broken toe should hurt more．It can be concluded from the text that _______．
A．the feeling of pain varies from one person to another k+s-5#u |
| B．long-lasting pain damages people’s health |
| C．pain is greater if harm seems to be intentionally done |
| D．people suffer more from accidental pain |
What can we infer from the text?
| A．People can reduce pain by relaxing． |
| B．Researchers study how pain is caused． |
| C．Everyone should know the effect of pain． |
| D．People should think more about pain． |
What does the underlined word “they” in the third paragraph refer to?
| A．Volunteers． | B．Computers． |
| C．Shocks． | D．Pains． |
What’s the author’s attitude to the result of the study? k+s-5#u
| A．Indifferent． | B．Sceptical． |
| C．Disapproving． | D．Approving． |
