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.
1.The underlined phrase “throws a fit” in Paragraph 4 probably means “________”．
A．gets angry B．gets sick
C．becomes hungry D．becomes cheerful
2.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
3.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.
4.What can be the best title for the text?
A．Mining Accidents in America
B．Could Robots Replace Humans in Mines?
C．Cave Crawler，the Latest Robot
D．The Development of Robots

In recent years many countries have been faced with the problem of how to make their workers more productive. Some experts believe that the answer is to make jobs more varied. Do more varied jobs lead to greater productivity? There is something to suggest that while variety certainly makes the worker's life more enjoyable, it does not make him work harder. So variety is not important.
Other experts feel that giving the worker freedom to do his job in his own way is important and there is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated machinery which must be used in a fixed way. Thus while freedom of choice may be important, there is very little that can be done to achieve this.
Another important consideration is how much each worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are said to be experimenting with having many small production lines rather than a large one, so that each worker contributes more to the production of the cars on his line. It would seem then that the degree of worker contribution is important.
To what extent does more money lead to greater productivity? The workers themselves certainly think this is important, but perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if companies succeed in making workers' jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.
72. Which of the following things will not increase productivity?
A. Making jobs more varied.
B. Longer working hours.
C. Giving workers the freedom to do his jobs in their own way.
D. Increasing the workers' contribution to production.
73. The last sentence in this passage means that if companies manage to make workers' jobs more interesting, _________.
A. they will want more money
B. they will demand shorter working hours
C. more money and shorter working hours are important
D. more money and shorter working hours will not be so important to them
74. In this passage, the writer tells us _________.
A. how to make the workers more productive
B. possible factors leading to greater productivity
C. more money leads to greater productivity
D. how to make workers' jobs more interesting
75. The writer of this passage is probably a _____________.
A. teacher B. worker C. manager D. physics

Babies who are slow to gain weight in the first months of their lives generally catch up to their peers by age 13,a large UK study shows, Researchers said the results would make parents whose babies fail to put on weight quickly less worried.
The researchers looked at data from ,11,499 children who took part in a large study, It showed that 507 who were slow to gain weight in the first eight weeks of life recovered fairly quickly and had almost caught up by age 2. Another group of 480 who were slow to gain between eight weeks and nine months continued to put on weight slowly until they were seven years ,but then had a sudden increase and caught up by age 13, The different pattems of recovery between the two groups were likely due to different reasons for slow weight gain ,the researchers said, All the children were still lighter and shorter than their peers by the time they were teenagers ,but within the normal range.
The findings highlight the importance of monitoring a baby’s weight and height gain during the first few weeks and months ,but not creating anxiety with parents of slow-growing babies, said the study leader Prof Alan Emond from the University of Bristol.
“In the past, a lot of parents have been caused unnecessary anxiety by heaith professionals and this is a positive and reassuring message.”He said in many cases of slow growth where children do not follow the standard’curve’(曲线)it is just because they are following their genetic potential.
Dr Simon Newell, vice-president of the Royal College of Paediatrics and Child Health, said he broadly agreed with the concluslons of the researchers but stressed that poor weight gain was something that needed to be monitored closely, “I would encourage parents to use growth charts but if measurements show your baby is smaller than averager it may be completely normal, ”he said.
1.What can we know from the findings of the research?
A、All the cases of slow weight gain in the first months of the babies’ lives are caused by the same reason
B、Slow-growing babies will have the same height and weight with their peers by age13
C、Many cases of children whose growth don’t meet the growing standard curve cannot be treated as abnormal
D、The findings won’t cause parents’ anxiety so monitoring a baby’s growth from his/her birth is unnecessary
2.Which of the following statements is true according to the passage?
A、It’s important to monitor a baby’s weight and height gain for new parents
B、New parents should feel anxious about their baby’s weight and height gain
C、Researches still couldn’t find the reasons for slow weight gain
D、All the children’s weight and height became normal by age 13
3.What does the underlined word in the fourth paragraph mean?
A、Making sure something is certain to be true
B、Making someone calmer and less anxious
C、Confirming something is to happen again
D、Being sure that someone can be attracted
4.Which of the statements would Dr Simon Newell agree to?
A、To some degree, growth charts can help parents monitor their babies’ weight gain
B、It’s abnormal for babies are smaller than average
C、He agreed with the researchers completely
D、Babies’ weight gain can only be monitored and measured by using growth charts.
5.The writer wrote this passage in order to ________
A、tell us how to help babies grow faster
B、explain why babies are gain weight slowly
C、report on the findings of a research
D、reduce the anxiety of some parents
