　　Have you ever imagined that you could be cloned like Dolly the sheep in the not too distant future?

　　The news that a human embryo (胚胎) has been 1 cloned for the first time has caused mixed reactions (反映).

　　The 2 was carried out by scientists from the Advanced Cell Technology Inc (ACT), in Massachusetts, US. The group 3 the news on November 25.

　　“This is 4 human being. A clone is alive, it walks, it breathes,” said Jamie Grifo, 5 on the study of cloning at New York University School of Medicine.

　　“This is a set of cells in a lab that will be used to 6 someone's life. ”

　　Such research could lead to treatment for 7 such as heart diseases, AIDS and even cancer, 8 scientists.

　　Despite high hopes from other scientists, the news raised concerns immediately from religious and political leaders. Several 9 in the US do not allow human cloning. President George W. Bush also made it clear that he is 10  any type of human cloning. However, the scientists at ACT said they have no interest at present in 11 an early embryo into __12__.

　　Animals have been cloned repeatedly since Dolly the sheep 13 in 1997. And there were no real technical 14 to stand in the way of scientists making a cloned human embryo.

　　This time the research group used traditional cloning technology with a human 15

　　 16 it was given DNA from an adult cell, the egg began to __17__.__18__ it was stopped from becoming a baby--at a stage in which it was 19 a ball of cells. The 20 technology has been used to clone sheep, cattle and monkeys.

Today just as technology changed the face of industry, farms have undergone an “agricultural revolution”. On the farm of today, machines provide almost all the power.
One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.
　　Another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand” that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.

You can only find reading materials badly made up there---some are too strange for anyone to 40 ,  others are frightening stories of something  41  .However, many of the young readers are getting interested in such  42  reading, which  43 them what they should pay for their breakfast and brings them nightmares（噩梦）and immoral（邪恶）ideas in  44 .  Homework is left  45 ,  and daily games are lost.

　　These sellers shout on streets selling their papers well. The writers, publishers and printers,  46  they are, we never know,  are  47 their silent money.

The sheep-skinned wolf's story seems to have been forgotten once again .Why not 48 this kind of thing? Yes, both teachers and parents have asked each other for more strict control of the young readers.  49  ,the more you want to forbid it, the more they want to have a look at it. 50  you may even find  several children, driven by the curious natures,  51  one patched paper,  which has travelled from hand to hand.

　　It really does 52  to our society. It has already formed a sort of moral pollution. The  53  teachers and parents need more powerful support in their protection of the young generation. At the same time the young 54  need more interesting books to help them  55  those ugly papers.

A desert is a beautiful land of silence and space. The sun shines, the wind blows, and time and space seem endless. Nothing is soft. The sand and rocks are hard, and many of the plants even have hard needles instead of leaves.

The size and location(分布) of the world’s deserts are always changing. Over millions of years, as climates change and mountains rise, new dry and wet areas develop. But within the last 100 yeas, deserts have been growing at a frightening speed. This is partly because of natural changes, but the greatest makers are humans.

Humans can make deserts, but humans can also prevent their growth. Algeria Mauritania is planting a similar wall around Nouakchott, the capital. Iran puts a thin covering of petroleum(石油) on sandy areas and plants trees. The oil keeps the water and small trees in the land, and men on motorcycles(摩托车) keep the sheep and goats away. The USSR and India are building long canals to bring water to desert areas.

In this passage, “needles” refers to _______.

A. small, thin pieces of steel.

B. long, thin pieces of branches.

C. small pointed growth on the stem(茎) of a plant.

D. small, thin pieces of sticks.

Which of the following is NOT true?

A. The greatest desert makers are humans.

B. There aren’t any living things in the deserts.

C. Deserts have been growing quickly.

D. The size of the deserts is always changing.

People in some countries are fighting a battle against _______.

A. the growth of deserts B. the disappearance of desert plants

C. natural changes  D. congenital climate

We can guess that Mauritania and Algeria belong to _______.

What is eco­fashion？Eco-fashion is about making clothes that take into account the environment, the health of consumers and the working conditions of people in the fashion industry.  It is a complex phenomenon and the common use of the term covers two aspects of fashion —‘ecological’ and ‘ethical’．Ecological fashion usually refers to textile (织物) and clothing production processes and the environmental issues surrounding them；ethical fashion generally relates to the working conditions involved in the producing processes.

What are the problems with fashion？A closer look at the fashion industry points out many problems that are common practices in the creation of our fashions from the field to the factory. Firstly，the production of textiles pollutes the environment heavily. Cotton­planting uses pesticides；sheep­farming and wool­cleaning contribute to global warming；synthetics­making (人造纤维生产) brings about waste which does harm to our environment. Secondly，every stage of clothing production has a significant effect on the environment. They all use a great deal of energy，and some also involve harmful chemicals. In addition to this，there is a lot of waste produced in the process，especially in the form of polluted water. Thirdly，growing consumption levels and our shopping habits further worsen the bad effects. We are now buying clothes in increasing quantities without realizing the scale on which it affects natural environment，and we are also quick to throw away clothes that have been worn only a couple of times.

Then，how to solve the problems? Other industries that design products are ahead of the fashion industry when it comes to choosing sustainable materials, designing for minimum waste, choosing energy efficient manufacturing and creating products for longevity. The fashion industry has been slow to adopt these changes and part of the problem is the very nature of fashion. To a large degree，it is the fashion producers that really have the power and the responsibility to shape our future. There are numerous ways in which these producers can reduce their ecological footprint，from switching to green energy and reducing energy use，through selecting sustainable materials and choosing local suppliers，to recycle and minimize waste. On the other hand，as consumers we can all make contributions by selecting environmentally friendly clothing and reducing clothing consumption.

There is some concern that eco friendly fashions are just a trend that we will eventually grow tired of but we can make sure that doesn't happen. Now many people are beginning to shop for organic food products because the benefits of eating food free of chemicals are straightforward and immediate. They relate directly to our personal health. In fact, choosing eco­fashion can also contribute to our personal health, though it is mostly done by way of keeping the health of the planet.
