【题目】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest.

Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes(纬度). To achieve giant size, a tree needs three things: the right place to establish its seeding, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees.

In some parts of the world, populations of big trees are dwindling because their seedings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear.

Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. “During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic(新陈代谢的)rate increases,” explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth.

The Clarks’ theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions.

Besides, big trees face threats from elsewhere.

【1】 All the following factors are a must for making big trees EXCEPT_________.

A. genetic contribution

B. no deadly damage

C. ideal environment for growth

【2】The word “dwindling”(paragraph3) is closest in meaning to “_______”.

A. exploding B. decreasing

C. changing D. growing

【3】 What is the best title of the passage?

A. Results of big trees’ disappearing.

B. Advantage of big trees.

C. Big trees in trouble

D. Importance of big trees to humans.

【4】What will the author most probably discuss after the last paragraph?

A. Comparison between common trees and big ones.

B. The effect of human activities on big trees.

C. Benefits of big trees to the whole atmosphere.

D. More threats to the existence of big trees.

【题目】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

“A Long Walk Home”-----life as Eli Reed saw it

American photographer and photojournalist Eli Reed has been documenting “life as I saw it” for more than 40 years. His career retrospective(回顾), “Eli Reed: A Long Walk Home”, is an extraordinary search of beauty while recording hardship. With a heart of love, Reed uses a style that uncovers humanity at every turn. According to Reed, “A Long Walk Home” is about what it means to be a human being. It all began with a photo he took of his mother and his memory of her smile.

Raised in New Jersey, Reed was originally a painter. Primarily self-taught in photography, he became a freelance photographer in 1970. After producing some impressive photos that drew much attention, he joined the famous company Magnum Photos---the first black photographer invited to do so.

His photos are remarkable in their lack of judgment of the people or the situations he comes across. In Beirut, Lebanon, a man removes a tree branch from a car in a recently bombed parking lot. An old man wrapped in a sheet plays a drum in front of a sign reading “God Is the Way” while National Guardsmen lift their guns during a war in Miami. A young boy upside down with his legs in the air in a Kenyan refugee camp, his determined look faces the camera. In Harlem, New York, a group of laughing children take over an abandoned car, using it as a jungle gym.

When another photographer might have focused on the sobriety of these situations, Reed’s camera smiles. His images show how humans cope, rise above, and carry on. This is what gives “A Long Walk Home” its power. Considering the places Reed has been to, there are very few photos of guns or obvious violence. Instead, Reed focuses on the varied human responses to hardship.

We smile along with Reed in a gesture of compassion and solidarity. We recognize our fellow human beings.

【1】Why did Eli Reed produce his work “A Long Walk Home”?

A.To pursue his love of photography

Do you have memories of being kidnapped (绑架)by aliens and taken away rapidly in a spaceship? You wouldnt be alone. Several thousand people worldwide reported to have had such experiences, researchers say. But in a new study, a psychology expert at Londons Goldsmiths College says these experiences are proof of the weakness of the human memory, rather than evidence of life in outer space.

Maybe what we’re dealing with here is false memories, and not that people are actually being kidnapped and taken aboard spaceships,” says Professor Chris French, who surveyed 19 so-called victims.

Several of the victims reported being taken away from their beds or cars by alien creatures around four feet high, with long and lean arms and legs and over-sized heads, French said. Some men said they were forced to take painful medical examinations by the aliens.

Many of the alien experiences could be explained by sleep paralysis, a condition in which a person is awake and aware of the surroundings but is unable to move. Sleep paralysis often leads to hallucinations —the experience of seeing or feeling something that is not really there and 40 percent of people experience the state at least once in their lives, French said. A rich imagination was also at play. Several of the alien victims were more likely to fantasize and reported to have seen ghosts and have unnatural abilities.

People have very rich fantasy lives,” said French, who is due to present his findings at a public seminar at London’s Science Museum on Wednesday. “So much that they often mix up what’s happening in their heads with what is going on in the real world.”

【1】According to Chris French, if someone told you an alien experience again, you might _____.

A. believe the story B. report it to the police

C. wonder why D. just laugh it away

【2】The underlined word fantasize in Paragraph 4 probably means _____.

A. have good memories B. tell the truth

C. use vivid imagination D. make up excuses

【3】What is the authors attitude towards alien experiences?

A. Puzzling B. Objective.

C. Respectful. D. Supportive.

【4】Where can this passage probably be found?

A. A science magazine. B. A textbook.

C. A science fiction. D. A storybook.

【题目】The Internet has become part of teenage life.
