which of the following sentences is right ?

A. It is the first time that I have seen Andy’s concert.

B. It was until her father came back that she didn’t go to bed.

C. We feel that our duty to help the people in disaster-stricken areas.

D. I’m about to go shopping tomorrow.

Years ago, when I started looking for my first job, wise advisers urged, “Barbara, be enthusiastic! Enthusiasm will take you further than any amount of experience.” How right they were! Enthusiastic people can turn a boring drive into an adventure, extra work into opportunity and strangers into friends.

“Nothing great was ever achieved without enthusiasm,” wrote Ralph Waldo Emerson. It is the paste that helps you hang in there when the going gets tough. It is the inner voice that whispers, “I can do it!” when others shout, “No, you can’t!” It took years and years for the early work of Barbara McClintock, a geneticist（遗传学家）who won the 1983 Nobel Prize in medicine, to be generally accepted. Yet she didn’t let up on her experiments. Work was such a deep pleasure for her that she never thought of stopping.

We are all born with wide-eyed, enthusiastic wonder and it is this childlike wonder that gives enthusiastic people such a youthful air, whatever their age. At 90, cellist Pablo Casals would start his day by playing Bach（巴赫）. As the music flowed through his fingers, his bent shoulders would straighten and joy would reappear in his eyes. As author and poet Samuel once wrote, “Years wrinkle（使生皱纹）the skin, but to give up enthusiasm wrinkles the soul.”

Enthusiastic people also love what they do, regardless of money, title or power. Patricia Mallrath, retired director of the Missouri Repertory Theater in Kansas City, was once asked where she got her enthusiasm. She replied, “My father, a lawyer, long ago told me, I never made a penny until I stopped working for money.”

 If we cannot do what we love as a full-time career, we can do it as a hobby. Elizabeth Layton of Wellsville, Kan, was 68 before she began to draw. This activity ended her depression（抑郁）that had troubled her for at least 30 years, and the quality of her work led one critic to say, “I am persuaded to call Layton a genius.”

We can’t afford to waste tears on “might-have-beens”. We need to turn the tears into sweat as we go after “what-can-be.” We need to live each moment whole-heartedly, with all our senses—finding pleasure in the sweet smell of a backyard garden, the simple picture of a six-year-old, and the beauty of a rainbow.

Which of the following can best explain the underlined sentence in Paragraph 2?

A. Enthusiasm can give you courage and strength in difficult times.

B. If you don’t have enthusiasm, you can achieve nothing.

C. Enthusiastic people never consider money and fame

We all enjoy the colors of autumn leaves. Did you ever wonder how and why a fall leaf changes color? Where do the yellows and oranges come from? To answer those questions, we first have to understand what leaves are and what they do.

      Leaves are nature's food factories. Plants take water from the ground through their roots. They take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose, which is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis, which means " putting together with light. " A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is what gives plants their green color.

      As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to begin getting ready for winter.

      During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange colors. Small a-mounts of these colors have been in the leaves all along. Covered up by the green chlorophyll, we just can't see them in summer.

     The bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color. The brown color of trees like oaks is made from wastes left in the leaves.

     It is the combination of all these things that make the beautiful colors we enjoy in the fall.

Researchers who helped discover a new species of Mexican butterfly are offering to sell the naming rights to raise money to fund more research. Co-discoverer Andrew Warren is hoping to raise at least $50,000 by auctioning(拍卖) off the rights to name the 4-inch “owl eye” butterfly, which lives in Sonora, a Mexican state bordering Arizona.

“That would support at least two years of research for our team down in Mexico,” Warren said. “Money goes a long way down here in Mexico.”

According to the scientific tradition, discoverers of a new species have the say in naming it. In recent years, some discoverers have auctioned off their naming rights to raise money.

Warren said the amount being sought for the butterfly is not out of the question, noting that naming rights for a new monkey species brought in $650,000 two years ago. A group of 10 new fish species that went on the naming auction block at the same time earlier this year brought in a total of $2 million.

The butterfly discovered by Warren and researcher George Austin ranges as far north as Mexico.

The butterfly was actually in a collection, misidentified as an example of another new species, at the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of National History in Gainesville, said Warren. They soon began the hard process of determining that it was indeed a “new” model of butterfly.

After checking photos and comparing it with other known species, they determined it was a separate species.

Where did the researchers discover the new species of butterflies?

   A. In Sonora.                        B. In Mexico state.       

   C. In a place in US.                D. Near the US-Mexico border.

Why will the researchers sell the naming rights of the butterfly?

To raise money for wildlife protection.

To raise money for more research.

To cause people’s attention to the new discovery.

To cover the cost of the research.

When the butterfly was first discovered, people thought ______.

it was a new species at once

it wasn’t a species of American butterfly

it belonged to the monarch branches

it belonged to a new species

We can infer from the passage that ______.

the new species of butterfly live both in the US and Mexico

it took the researchers a lot of efforts to determine the new species of butterfly

the researchers are not sure whether they can get the money they want from the auction

it is the first time that the new species of butterfly has been found
