Why should man take the trouble of conquering space? It is hard to list the specific practical benefits that will result in. But one knows, from past experience in other areas, that man will surely see and discover new things in space that will increase our scientific knowledge, and this new knowledge will find its way into valuable practical uses. What we learn abou
t man himself, from his experience in space, and from the effects of space and the space flight environment on him, will be extremely valuable. The new techniques developed to carry out the exploration of space, and to keep man alive in space, will certainly find practical uses in everyday life 
in some way. The areas that will benefit are manifold. They include communication, generation of power, transportation and travel, food production, materials, fuels and many others. But to say definitely just what the practical results will be is almost impossible.小题1:

urope and Asia along the Silk Road probably began in some form many centuries earlier than once thought. The findings, coupled with a widening range of scientific and historical research could add a fascinating new page to the epic (史诗) of the Silk Road. The most surprising discovery is pieces of silk found in the hair of an Egyptian mummy from about 1000 BC, long before regular traffic on the Silk Road and at least one thousand years before silk was previously thought to be used in Egypt. Other research may extend human activity along this route back even further, perhaps a million years to the migration of human ancestors into eastern Asia.
The official origin of East-West trade along the road is usually placed in the late 2nd century BC when an agent of the Chinese Emperor Wu-di returned from a dangerous secret mission（使命）across the desert into the remote high country of Central Asia. The agent, Zhang Qian, travelled as far as Afghanistan and brought back knowledge of even more distant lands such as Persia, Syria and a place known as Lijien, perhaps Rome. Historians have called this one of the most important journeys in ancient times. His journey opened the way for what have been thought to be the first indirect contacts between the ancient world’s two superpowers, China and Rome. Chinese silk, first traded to central Asian tribes for war horses and to the Parthian for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury (奢侈品) markets in Rome.
But the new discoveries show that Chinese silk was apparently present in the West long before the Han emperor started organized trade over the Silk Road. The research could change thinking about the early history of world trade and provide insights into the mystery of just how and when Europe and the Mediterranean lands first became aware of the glorious culture at the other end of Eurasia.
小题1:The word “coupled” in the first paragraph could best be replaced by .
| A．combined | B．contributed | C．doubled | D．produced |
| A．Egyptians had probably travelled to China to buy silk |
B．new light can now be thrown on ancient trading pr actices |
| C．historical research often achieves fascinating results |
| D．trade along the Silk Road began earlier than once thought |
| A．began a million years ago |
| B．primarily benefited the Egyptians |
| C．originated in the 2nd century BC |
| D．extended human migration into eastern Asia |
| A．he discovered the Silk Road |
| B．he helped establish East-West trade |
| C．he travelled as far as Afghanistan |
| D．he brought back knowledge of Rome to the emperor |
So, we can clone things, but why would we want to?
Of all the reasons, cloning for medical purposes has the most potential to benefit large numbers of people. How might cloning be used in medicine?
1. Cloning animal models of disease
Much of what researchers learn about human disease comes from studying animal models such as mice. Often, animal models are genetically engineered to carry disease-causing mutations(变异) in their genes. Creating these transgenic（转基因的） animals is a time-intensive process that requires trial-and-error and several generations of breeding（培育）. Cloning technologies might reduce the time needed to make a transgenic animal model, and the result would be a population of genetically identical animals for study.
2．Cloning stem cells(干细胞) for the treatment of diseases
Stem cells are the body"s building blocks, responsible for developing and repairing the body throughout life. As a result, they might be used to repair damaged or diseased organs and tissues. Researchers are currently looking up cloning as a way to create certain human stem cells for the research of diseases.
3. Cloning farm animals for drug production
Farm animals such as cows, sheep and goats are currently being genetically engineered to produce drugs or p
roteins that are useful in medicine. Just like creating animal models of disease, cloning might be a faster way to produce large herds of genetically engineered animals. 小题1:From Purpose One, we can infer that .
| A．most transgenic animals are clone |
| B．most animals carry engineered genes |
| C．most transgenic animal models are not cloned |
| D．most animals carry disease-causing mutations in their genes |
| A．create damaged or diseased organs and tissues |
| B．clone genetically defined human stem cells |
| C．develop and maintain the body |
| D．repair the body throughout life |
| A．speed up the producing of genetically engineered animals |
| B．produce drugs or proteins that are useful in medicine |
| C．raise genetically engineered cows, sheep and goats |
| D．produce large herds of animals for human beings |

The Scottish teacher who received it in class had no idea what the girl who wrote it meant. The essay was written in a form of English used in cell phone text messages. Text messages (also called SMS2) through cell phones became very popular in the late 1990s. At first, mobile phone companies thought that text messaging would be a good way to send messages to customers, but customers quickly began to use the text messaging service to send messages to each other. Teenagers in particular enjoyed using text messaging, and they began to create a new language for messages called texting.
A text message is limited to 160 characters, including letters, spaces, and numbers
, so messages must be kept short. In addition, typing on the small keypad of a cell phone is difficult, so it’s common to make words shorter. In texting, a single letter or number can represent a word, like “r” for “are,”“u” for “you,” and “2” for “to.” Several letters can also represent a phrase, like “lol” for “laughing out loud.” Another characteristic of texting is the lea
ving out of letters in a word, like spelling “please” as “pls.”Some parents and teachers worry that texting will make children bad spellers and bad writers. The student who wrote the essay at the top of this page said writing that way was more comfortable for her. (The essay said, “My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three kids face to face.”)
Not everyone agrees that texting is a bad thing. Some experts say languages always evolve, and this is just another way for English to change. Other people believe texting will disappear soon. New technology for voice messages may soon make text messages a thing of the past.
小题1:What is the writer’s opinion of text messaging?
| A．It is fun and easy to do. |
| B．It is not bad for children. |
| C．It will make children bad writers. |
| D．The writer does not give an opinion. |
| A．Using phrases to represent essays |
| B．Using numbers to represent words |
| C．Using letters to represent phrases |
| D．Using letters to represent words |
| A．My Gr8 Tchr | B．CU in LA | C．My GF | D．My Smmr Hols |
| A．It costs too much. | B．It’s too difficult to type. |
| C．Children won’t learn to write correctly. | D．It’s not comfortable. |
| A．Not many people use texting. |
| B．Spelling in English is too difficult. |
| C．Children quickly become bored with texting. |
| D．Texting will disappear because of new technology. |
Teenagers also cause discipline(纪律)problems. As a teacher I had a 16-year-old student who had fallen in love with a waiter at a fast-food restaurant. In fact, she had left home to stay with him. So we decided to put her in the school hostel .She refused. When she heard her mother begging her to stay in the school hostel, she turned around and said: “Why don’t you stay in the school hostel if you like it so much?”
My hands were going to slap her for being so rude but the poor mother continued to cajole her , hoping the gentle persuasion would work wonders. It did not. Later I heard that she had run away from home again.
The list goes on and on. Could it be that today’s parents are so softer and believe that they must not rod(棍棒惩罚)their children for fear of the bad results? Or do they really believe that the children will get rid of the bad habits and behave well as they grow older? I beg to disagree. I believe it is the parents’ duty to disc
ipline the children even at a young age.My children who are now adults will prove the fact that I used the rod when I thought it necessary. Later when they went abroad, they told their university friends how they were disciplined. Their friends were shocked and said that I could be charged with child abuse. However ,my daughter showed great respect for me when she told them that she would not be where she was today if not for my strict discipline.
小题1:According to the passage, the author would probably________.
| A．beat the children every day | B．treat the children in a soft way |
| C．leave the children as they are | D．punish the children when necessary |
| A．persuade | B．scold | C．forgive | D．punish |
| A．rod their children | B．punish their children |
| C．discipline their children | D．discipline and punish their children if necessary |
| A．The naughty boy’s mother hit him |
| B．The teacher’s daughter lived with her mother |
| C．The daughter was thankful for her mother’ strict discipline |
| D．The author was charged with child abuse by the daughter’s friends |
