第三部分 阅读理解（共两节，满分40分）

第一节（共15小题；每小题2分，满分30分）

　　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，并在答题卡上将该项涂黑。

A

　　Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist(气象学者) has done some estimates and the results might surprise you.

Let's start with a very simple white puffy cloud — a cumulus cloud（积云）. How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful … think of elephants."

The thought of a hundred elephants-worth of water suspended(悬浮的) in the sky begs another question — what keeps it up there?

　　"First of all, the water isn't in elephant-sized particles（微粒）, it's in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that's rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says.

So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.

　　Now, ratchet up(略微调高) the calculations for a hurricane about the size of Missouri and the figures get really massive(巨大的). "What we're doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by(乘上) the number of meters in a whole hurricane," she explains.

The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.

36．The weight of is NOT mentioned in the passage.

　A. a cumulus cloud B. a tornado C. a hurricane D. a storm cloud

37．How did Peggy LeMone feel about the result of her calculations?

　A. She found it not convincing.

　B. She thought it needed further calculations.

　C. She was quite surprised at it.

　D. She considered the calculations inaccurate.

38．What can be inferred from the passage?

　A. A storm cloud weighs about 200,000 elephants.

　B. The water in a hurricane weighs more than that in any other kind of cloud.[来源:Z.X.X.K]

　C. There are less than forty million elephants living on the earth.

　D. The water in the cloud is in very tiny partials.

39．What is the best title for the passage?

　A. How Much a Cloud Weighs B. How Much a Hurricane Weighs

　C. Surprising Results D. Elephants in the Sky

　　Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour. The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.

　　Scientists have changed the colour of a dark-striped zebra fish to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebra fish skin colour is determined by pigment cells, which contain melanosomes (黑色素体). The number, size and darkness of melanosomes per pigment cell determines skin colour.

　　It appears that, like the golden zebra fish, light-skinned Europeans also have a mutation (突变)in the gene for melanosome production. This results in less pigmented skin. However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra fish genes.

　　Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun, which can cause skin cancer. But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng. Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin colours, said Cheng.

　　The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like
