The trip to that city was eye-opening for everyone, and near its end , all the young people in our group began to reflect on what it had meant. We __21__ the first night we had arrived. We had all gone into the markets of the city __22__ the young people could experience its energy. But what we actually saw simply   23  us all –the rundown houses, the children in rags, the people begging for money… Walking home,  24   under a low bridge, we came across  25   families of homeless people seeking a bit of dry ground to sleep on  26   he night. We had to step over bodies as we found our way through the darkness.

The poverty(貧困) was  27   than anything my young companions had ever imagined. Back in the hotel, an air of sadness settled over the group. Many  28   and cried. Spending time in this  29   moves a person to care about humanity.

That evening, our group spent hours talking about what we had  30  . Gently, I encouraged everyone to talk about the difficult  31   that day’s discoveries had inspired. Sitting together  32   a circle as everyone had a chance to speak, we all began to realize that  33   of us was alone in our struggle to cope with our reactions.

Based on my  34   in poverty-stricken areas, I suggested that  35   the emotions we had were painful, they could also be important in helping us to move forward. We all  36   that we had seen things that should never be allowed to happen.  37   , what could we do about it? Together, we began to brainstorm ways we could help to ease the  38   we had seen. As I encouraged group members to focus on  39   they could do, a sense of determination  40   the previous sadness. Instead of despair, these young people began to feel a call to action.

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.

49. 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

50. 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.

51. 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

52 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

Four people in England back in 1953, stared at Photo 51,It wasn’t much—a picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showed –the shape of DNA The discovery brought fame and fortune to scientists James Watson, Francis Crick, and Maurice Wilkins. The fourth, the one who actually made the picture, was left out.

   Her name was Rosalind Franklin.”She should have been up there,” says historian Mary Bowden.” If her photos hadn’t been there, the others couldn’t have come up with the structure.” One reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholars doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitors

   At Cambridge University in the 1950s, Watson and Click tried to make models by cutting up shapes of DNA’s parts and then putting them together. In the meantime, at King’s College in London, Franklin and Wilkins shone X-rays at the molecule(分子). The rays produced patterns reflection the shape.

   But Wilkins and Franklin’s relationship was a lot rockier than the celebrated teamwork of Watson and Crick, Wilkins thought Franklin was hired to be his assistant .But the college actually employed her to take over the DNA project.

What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return, “Mere inspection suggested that she would not easily bend. Clearly she had to to go or be put in her place.”

As Franklin’s competitors, Wilkins, Watson  and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. In 1962 at the Nobel Prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin, Watson wrote his book laughing at her. Crick wrote in 1974 that  “Franklin was only two steps away  from the solution.”

 No, Franklin was the solution. “She contributed more than any other player to solving the structure of  DNA . She must be considered a co-discoverer,” Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the  “Dark Lady of DNA”, Franklin is finally coming into the light.

57. What is the text mainly about?

   A. The disagreements among DNA researchers.

   B. The unfair treatment of Franklin.

   C. The process of discovering DNA.

   D. The race between two teams of scientists.

58. Watson was angry with Franklin because she     .

   A. took the lead in the competition         B. kept her results from him

   C. proved some of his findings wrong       D. shared her data with other scientists

59. Why is Franklin described as  “Dark Lady of DNA”?
   A. She developed pictures in dark labs.

   B. She discovered the  black X-the shape of DNA.

   C. Her name was forgotten after her death.

   D. Her contribution was unknown to the public.

60. What is the writer’s attitude toward Wilkins, Watson and Crick?
  A. Disapproving.     B. Respectful.        C.  Admiring.       D. Doubtful.
