Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (缝合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle (脚踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical. It could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement (侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties (版税). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小题1:Barthelemy Thimonnier’s garment factory was burned down because __________.
| A．people did not know how to put out the fire |
| B．Elias Howe thought Thimonnier had stolen his invention |
| C．the sewing machines couldn’t work finally |
| D．workers who feared the loss of their jobs to a machine set fire |
| A．Because the judge was against Singer for his unfriendly attitude. |
| B．Because Howe had already patented the lockstitch used by Singer. |
| C．Because Singer had borrowed money from Howe and never repaid it. |
| D．Because Singer and Howe had both invented the same machine. |
| A．A Stitch in Time Saves Nine |
| B．The Case between Howe and Singer |
| C．Patent Laws on the Sewing Machine |
| D．The Early History of the Sewing Machine |
答案
小题1:D
小题2:B
小题3:D
解析
小题1:细节理解题。第三段大意是：Barthelemy Thimonnier 的制衣厂被一群愤怒的裁缝烧了，因为他们担心会因为这个机器而丢了工作。 故选D。
小题2:细节理解题。 最后一段的大意：法庭强迫Isaac Singer付给Elias Howe专利税。因为Isaac Singer没有经过Elias Howe同意，就使用了他已经申请了专利的双线连锁缝纫法。Howe控告Singer侵权并获胜，而Singer被要求付给Howe版税。故选B。
小题3:主题归纳题。通读全文判断，全文介绍了缝纫机从无到有，从手动到脚动的过程，以及几个发明人之间的故事。所以最佳题目应该是缝纫机的早期历史。故选D。

Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil， which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emission (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate (加速) the change from traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.
小题1: The traditional business model is harmful because of all the following EXCEPT that ______.| A．it makes the world warmer |
| B．it consumes natural resources |
| C．it brings severe damage to forests |
| D．it makes growth hard to continue |
小题2:What can we infer from Paragraph 2?| A．China lacks wind and solar energy. |
| B．China is the leader of the low carbon market. |
| C．High speed trains are a low carbon development. |
| D．Palm oil is made at the cost of valuable forests. |
小题3:To fully develop the low carbon markets, government can ______.| A．cut public expenses | B．forbid carbon emission |
| C．develop public resources | D．encourage energy conservation |
小题4:We can learn from the last paragraph that businesses have many chances to ______.| A．develop sustainable products |
| B．explore new natural resources |
| C．make full use of natural resources |
| D．deal with the major challenge |
小题5:What is the main purpose of the passage?| A．To introduce a new business model. |
| B．To compare two business models. |
| C．To predict a change of the global market. |
| D．To advocate (提倡) sustainable development. |
But the new research, published in the journal Frontiers In Evolutionary Psychology, points out that serotonin is like a chemical Swiss Army knife, performing a very wide range of jobs in the brain and body. And when we start changing serotonin levels purposely, it may cause a wide range of unwanted effects. These can include digestive problems and even early deaths in older people, according to the study"s lead researcher Paul Andrews. “ We need to be much more cautious about use of these drugs,” says Andrews, an assistant professor of evolutionary psychology at McMaster University in Ontario, Canada.
Previous research has suggested that the drugs provide little benefit for most people with mild depression, and actively help only a few of the most severely depressed. Famous psychologist Irving Kirsch has found that for many patients, SSRIs are no more effective than a placebo pill. A research in 2010 on Danish children found a small, but significant, increase in the risk of heart problems among babies whose mothers had used SSRIs in early pregnancy. The key to understanding these side-effects is serotonin, says Andrews. Serotonin is also the reason why patients can often end up feeling still more depressed after they have finished a course of SSRI drugs. He argues that SSRI antidepressants disturb the brain, leaving the patient an even greater depression than before.
“After long use, when a patient stops taking SSRIs, the brain will lower its levels of serotonin production,” he says, adding that it also changes the way receptors in the brain respond to serotonin, making the brain less sensitive to the chemical. These changes are believed to be temporary, but studies indicate that the effects may continue for up to two years.
Most disturbingly of all, Andrews" review features three recent studies which, he says , show that elderly antidepressant users are more likely to die earlier than non-users, even after taking other important variables into account. One study, published in the British Medical Journal last year, found patients given SSRIs were more than 4 per cent more likely to die in the next year than those not on the drugs.
“Serotonin is an ancient chemical,” says Andrews. “It is regulating many different processes, and when you disturb these things, you can expect that it is going to cause some harm.”
Stafford Lightman, professor of medicine at the University of Bristol, and a leading UK expert in brain chemicals and hormones, says Andrews’ review highlights some important problems, yet it should also be taken with a pinch of salt. “This report is doing the opposite of what drug companies do,” he says. “Drug companies selectively present all the positives in their research, while this search selectively presents all the negatives that can be found. Nevertheless, Andrews" study is useful in that it is always worth pointing out that there is a downside to any medicine. ” Professor Lightman adds that there is still a great deal we don"t know about SSRIs-not least what they actually do in our brains.
When it comes to understanding why the drugs work only for a limited part of patients, U.S. scientists think they might now have the answer. They think that in many depressed patients, it’s not only the lack of feel-good serotonin causing their depression, but also a failure in the area of the brain that produces new cells throughout our lives. This area, the hippocampus, is also responsible for regulating mood and memory. Research suggests that in patients whose hippocampus has lost the ability to produce new cells, SSRIs do not bring any benefit.
小题1:According to paragraph 2, serotonin, like a chemical Swiss Army knife, can .
| A．make many patients" depression worse |
| B．cause a wide range of unwanted effects |
| C．affect human body and brain in various ways |
| D．provide little benefit for most depressed people |
| A．drug companies don"t know the negative effect of antidepressants |
| B．Andrews focused on different things from the drug companies |
| C．scientists have found what SSRIs do in the brain |
| D．Andrews" research has no medical value |
| A．They are used to increase the “feel-good” medical in the brain. |
| B．They can work even when the hippocampus can"t produce new cells. |
| C．They create a risk of heart problems in pregnant women. |
| D．They are responsible for controlling mood and memory. |
| A．The aim of drug companies |
| B．The function of SSRIs |
| C．The side-effects of antidepressants |

Various non-traditional education options are now available and continue to flourish（繁荣）. One of the most important uses in education is the use of technology. Teachers are encouraged to use new technological devices in order to strengthen learning among students and meet the needs of various types of learners.
The right to education has been created and recognized by jurisdiction（司法）. Education is the most important concern of the government of India. Recently India has gained world recognition because many students from foreign countries come here to gain higher qualifications.
One has to be educated in order to speed up the growth process in order to influence the economy. Education is indeed a powerful weapon to stop the cut- throat competition that man faces at every period of life. The importance of education in India is progressing with time. Although India has been a great foundation of learning for many years, it still needs to improve not just on the quality of education but also on the number of people being educated.
Education is not just for academic success but also to make a person become a better human being and a better performer in life. Education makes the students able enough, so that they can compete nationally and internationally. To make a student a successful survivor in life, the responsibility lies equally with the schools and the parents too. Selecting a good school is as important as choosing a suitable career option for a child. The goal of education is the advancement of knowledge and the dissemination of truth, it is education that gives us all the power and necessities of making a difference in any field.
People who are not educated have few opportunities to do what they want to do. Educated people become more responsible and informed citizens, and have a voice in politics and society. It allows people to be more productive by encouraging them to play responsible roles in terms of contributing to society.
小题1:Nowadays teachers are encouraged to ______.
| A．study modern science and technology |
| B．pass all knowledge to their students |
| C．use non-traditional devices in class |
| D．meet the needs of intelligent student first |
| A．Indian education is among the best in the world now |
| B．Indian is becoming more and more powerful now |
| C．the right to education should be valued all over the world |
| D．a lot of students in India are from other countries |
| A．spread | B．ignorance | C．argument | D．question |
| A．It has nothing to do with society |
| B．It helps people to achieve what they want |
| C．It has little effect on people’s physical ability |
| D．It makes a poor man become rich |
| A．The importance of education | B．The responsibility of education |
| C．The development of education | D．The purpose of education |
We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures. These resemblances have caused many people to consider a centuries-long project: to terraform Mars. Terraforming means altering a planet’s surface so that Earth’s life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists.
Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth. But it will take at least 300 years.
Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt. The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support. Our very existence and numbers are threatening many other species. We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate. Currently terraforming earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places.
While the possibility of such a project is small, it is not impossible .Even if earth –bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth.
The future existence of all the people in our world may very well depend upon our ability to terraform Mars.
小题1:What would be the best title for this passage?
| A．Terraforming Mars. | B．Saving the Earth |
| C．Travelling to Mars. | D．A Newly-found Place |
| A．Warming. | B．Changing. | C．Planting. | D．Building |
| A．do some scientific research work |
| B．find out its similarity to earth |
| C．avoid the dying away of many other species |
| D．find on Mars living place for the increasing human beings |
| A．there are some resemblances between Earth and Mars. |
| B．terraforming Mars is theoretically simple |
| C．we have had some experience with terraforming our own planet: Earth |
| D．the development of science and technology is very rapid |
| A．Optimistic. | B．Negative |
| C．Sceptical（怀疑的） | D．Objective. |
