As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at 31 . Its cells would grow old fast and it would die young. 32 until the technique is perfectly safe, it should be 33 .
I"d love to have a clone of 34 . I often wish I had a twin sister, someone who 35 me in everything. So why not a clone? Well, the idea 36 be fun but I"m not sure if it would be 37 . I think we would be playing with fire if we let scientists go ahead with 38 cloning. There are so many 39
involved that all research in this area should be strictly controlled.
There are so many arguments 40 cloning that it is difficult to get anyone to consider the possible benefits. I am 41 that it is a technique which could be beneficial. The most obvious use would be for childless 42 . They would be able to have babies with their own genetic material. I don"t see what"s wrong with that.
Imagine a child 43 up knowing that his or her mother is really a sister or a brother. The emotional 44 on the child would be 45 . Or a child who was cloned from a dead brother or sister. What kind of emotional pressure would they feel, knowing they were made as a replacement for another? The whole idea
46 me!
It"s all very good to ban human cloning but scientists should be allowed to 47
research. If they don"t, we may 48 important benefits for our society, such as producing body organs. A clone is an 49 copy of a person with the same gene. Therefore, it is the 50 donor for an organ(器官) transplant.

举一反三
The butterfly Ecological Park, which opened early this May, is located in Dabao Village in Longfeng Township of Pengzhou City, some 65 kilometers to the north of Chengdu downtown.
The park, covering an area of 67 hectares, is more famous for a variety of butterflies living in lush surroundings and houses a collection of some 30,000 butterfly species. An ideal site for parents and kids alike to enjoy the sight of “the flying flowers” and the ecological area.
A great variety of butterflies live in China, and Sichan and Yunnan are rich in butterfly resources. At present, 702 species have been discovered in Sichuan, where the number of butterfly species equals to the total of Europe. In the Longmen Mountain of Pengzhou City alone, there are more than 500 species.
The butterfly Ecological Park, a project of RMB200 million at the foot of the Longmen Mountain, is the natural habitat of butterflies. The park also has educational and cultural programs. The park has prepared many spring and summer activities for visitors, including a scientific exhibition about butterflies, a “butterfly valley” where visitors can have a close look at butterflies, even with them resting on the shoulders, and enjoy themselves in activities designed for children.
Tourists can enjoy the splendid scenery of thousands of butterflies at the “butterfly valley” and appreciate more than 30,000 different kinds of butterfly species at the exhibition area. Classified as the only category I butterfly species the Wild Animal Protection Law in 1989 in China, the Golden Kaiserihind is the most expensive species living in “butterfly valley”, with an estimated value of RMB10,000 each.

Today just as technology changed the face of industry, farmers have undergone an "agricultural revolution". On the farm of today, machines provide 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(猪) 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. 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(修剪) 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 special barn(畜棚), 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.
小题1:Which sentence carries the main idea of the whole passage? | A．The first sentence of the first paragraph. | | B．The first sentence of the second paragraph. | | C．The first sentence of the third paragraph. | | D．The last sentence of the second paragraph. |
小题2:Which of the following statements is true? | A．Farmers in the future will depend totally on computers. | | B．Both computers and robots have been in use on today"s farms. | | C．Farmers mainly use machines on their farms at present. | | D．Farmers can do nothing without the help of computers on today"s farms. |
小题3: According to the engineers,_____________ will be done by robots in the near future.| A．all farm work | B．milking cows | | C．most of the farm work | D．some house work |

Light for the City
Edison and his assistants came to New York to set up an electric power system. They hoped it would provide enough electricity to light up a part of the great city.
They bought several machines with them. These were called generators(发电机), which produced electricity power for lamps in Edison’s building.
Soon there were lights for the building. Edison lived in a room facing the street and he often worked over night. The light burned brightly and steadily and he often worked over night. People often came and stopped their horse-drawn carriage to look. Everyone knew that Thomas Edison was in town.
First, the inventor and his assistants produced several large generators. A great deal of power would be needed to light up even a small part of the city. Then the workers were busy digging deep trenches in the hard earth below the city streets, and Edison had fourteen miles of wire laid into the trenches. The wire connected each building to a generator.
Setting up an electric power system was not an easy job. It took a year and a half. In September, 1882, the job was finished.
A small group of men stood around Edison inside the power house. The big moment came at last. The inventor, taking a deep breath, pulled a switch. The electric lights flashed up.
“Very good! Very good!” a man nearby shouted to praise Edison for what he had done.
“Sir,” said Edison, “this is only the beginning!” And Edison was right. Soon Edison’s lamp were lighting up cities all over the world.
小题1:The generators they brought with them could produce as much as electricity as ______ needed.| A．Edison’s building | B．a small part of the city | | C．the whole city | D．the world |
小题2:Trenches were dug to ______.| A．set up generators | B．lay wires | C．built city streets | D．build a power house |
小题3:It took a year and a half to ______.| A．set up the electric system | | B．produce several large generators | | C．dig the deep trenches | | D．lay fourteen miles of wire into the trench |
小题4:Edison took a deep breath before pulling a switch, which showed that he was ______.| A．excited | B．frightened | C．uneasy | D．light-hearted |

By 2050
Futurologists（未来学家）predict that life will probably be very different in 2050.
TV channels（频道）will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.
Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.
Robots will have replaced people in factories. Many factories already use robots. Big computers prefer robots—they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.
Medical technology will have conquered many diseases. Today, there are devices（设备）that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.
Scientist will have discovered how to control genes（基因）. Scientists have already produced clones（克隆）of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
小题1:According to the passage, the following can be realized today EXCEPT __________. | A．reading newspapers on a computer | | B．making a space shuttle go into space and land on Earth again | | C．creating cloned animals | | D．choosing TV programs freely from a “menu” |
小题2:We can learn from the passage that some big companies prefer robots to human workers, because human workers __________.| A．can work 24 hours a day | | B．often ask for more pay | | C．are not clever enough | | D．are often late for work |
小题3:From Paragraph 5 we can infer that __________.| A．there will be no blind and deaf people by 2050 | | B．few diseases will attack people by 2050 | | C．devices are connected directly to the brain to help people hear | | D．medical technology will be more effective by 2050 |
小题4:What is the author’s attitude towards the cloning technology?| A．The author does not support the use of cloning technology. | | B．The author thinks human cloning is impossible. | | C．The author does not really support the idea of human cloning. | | D．The author is quite excited about human cloning. |

A farm planted levels or floors is called a vertical（垂直的）farm. A skyscraper type building can house a vertical farm. Since the garden is built upwards，rather than outwards，it requires much less space than a conventional farm.
The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18story vertical farm could feed as many as 50,000 people，all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time，food would be delivered in fresher condition and with less damage.
There is a growing concern about the use of pesticides(***虫剂) in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space，therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics(水耕法) could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course，not all food does well with this type of planting，but there are many crops that actually seem to do better.
In some climates，a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words，we could grow crops in areas where we never could before.
Vertical farms may just be a concept for now，but they are a concept that will solve many of our problems in the future.
小题1:According to the passage, a vertical farm________.| A．is mainly built outwards | | B．is dependent on solar power | | C．is planted on levels upwards | | D．is only an environmental friendly farm |
小题2:Compared to the conventional farm, the vertical farm can________.| A．depend far less on sunlight | | B．greatly increase the use of soil | | C．help to protect the limited gardens | | D．reduce the use of harmful pesticides |
小题3:It can be learned from the passage that vertical farms________.| A．have been put into use | | B．only use hydroponics to grow food | | C．need less room than conventional farms | | D．may increase the transportation costs |
小题4:What would be the best title for the passage?| A．Vertical farms for our future | | B．Ways to deal with future problems | | C．Vertical farms and green skyscrapers | | D．Making Full Use of Our Limited Land |
