By 2050
Futurologists（未來學(xué)家）predict that life will probably be very different in 2050.
TV channels（頻道）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（設(shè)備）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�。﹐f 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?

【小題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

Mary Cassatt is one of the first great women American painters. At first her father did not want her to become an artist. But she followed her dreams and became an artist.She was born on

May 22, 1844, and lived in Europe for several years as a child.

   Her family returned to the United States and, at age 16, Mary attended the Pennsylvania Academy of Fine Arts.

They recognized Mary 's spirit and powerful talent and invited her to exhibit in the Impressionist art shows.

   Mary never married and, in 1877, her parents and sister moved to Europe to join her. Mary devoted much of her time to them for the next 18 years to their care. Mary painted until 1914 when her failing eyesight made it impossible to continue. She spent the later years of her life in Paris. She died in 1926 at the age of 82.

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants Produce volatile compounds, chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from volatile compounds that the plant produces to attract insects such as Bugs and bees.

Plants can also detect volatile compounds produced by other plants. A tree under attack by Hungry insets, for instance, may give off volatile compounds that let other trees know about the Attack. In response, the other trees may send off chemicals to keep the bugs away ——or even  Chemicals that attract the bugs’ natural enemies.

Now scientists have created a quick way to understand what plants are saying: a chemical Sensor（傳感器）called an electronic nose. The “e-nose” can tell compounds that crop plants make When they’re attacked Scientists say the e-nose could help quickly detect whether plants are being Eaten by insects. But today the only way to detect such insects is to visually inspect individual Plants. This is a challenging task for managers of greenhouses, enclosed gardens than can house Thousands of plants.

The research team worked with an e-nose than recognizes volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds Based on these interactions, the e-nose gives off electronic signals that the scientists analyze using computer software.

To test the nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all common greenhouse crops. Then scientists collected samples of air around damaged leaves from each type of crop, These plants had been damaged by insects, or by scientists who made holes in the leaves with a hole punch（打孔器）. The e-nose, it turns out, could identify healthy cucumber, pepper and tomato plants based on The volatile compounds they produce, It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage ---- by insects or with a hole Punch ---- had been done to the tomato leaves.

With some fine-tuning, a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, Ind. who studies smells of flowers and plants. Hopefully, scientists believe, the device could bring large benefits to greenhouse managers in the near future.

We learn from the text that plants communicate with each other by____.

A. making some sounds        B. waving their leaves

C. producing some chemicals   D. sending out electronic signals

What did the scientists do to find out if the e-nose worked?

A. They presented it with all common crops.

B. They fixed 13 sensors inside the device.

C. They collected different damaged leaves.

D. They made tests on damaged and healthy leaves.

According to the writer, the most amazing thing about the e-nose is that it can___.

A. pick out ripe fruits

B. spot the insects quickly

C. distinguish different damages to the leaves

D. recognize unhealthy tomato leaves

We can infer from the last paragraph that the e-nose_____.

A. is unable to tell the smell of flowers

B. is not yet used in greenhouses

C. is designed by scientists at Purdue

D. is helpful in killing harmful insects
