题目内容

---Are there any books related to the situation around Diaoyu Island?

---There’re only a few, ________.

A. if some B. if any C. if many D. if ever

【答案】

【解析】

试题分析：考查if`条件状语从句省略。A无这种表达；B if any= if there are any如果有（某物）的话；C if many=if

there are many如果有许多的话；D 如果曾经做过的话（指动作）。根据语境“There’re only a few”可知是“有某物，但不多”，if ever一般指动作，不符合语境，故选B。句意：——是否有一些关于钓鱼岛的情况的书籍？——如果有的话，只有几本。

Have you ever heard a news reporter talk about DNA? Reporters talk about DNA found at the scene of a crime. They talk about police finding DNA “fingerprints.” Police sometimes use DNA as a clue to find out who committed the crime.

DNA is a substance（物质） that makes up genes. Everything alive has genes. Plans have genes. Animals have genes. You have genes.

Genes are the basic units of heredity（遗传）. Heredity means all the characteristics you inherit from your parents. You get your genes from your parents. You inherit half of your genes from your mother. You inherit half of your genes from your father.

Genes are a kind of code. A tree’s genes tell what shape its leaves will be. A cat’s genes tell what color its fur will be. Your genes tell what color your eyes will be. Your genes tell what color your hair will be. Everything about you comes from the code in your genes.

Genes line up on strands（链） called chromosomes（染色体） in cells. Everything alive is made up of cells. Chromosomes are in the center, or nucleus, of cells.

Different parts of you are made of different kinds of cells. Your muscles are made of muscle celIs. Your skin is made of skin cells. The code in your genes tells your body to make different kinds of cells. The genes in each cell tell the cell how to work. They tell the cell when to make new copies of itself.

An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants. He experimented with pea plants in the 1860s. One of the things, or traits（特质）， Mendel studied was what makes some pea plants tall and some short. He said that the traits must come from units of heredity passed from the parent plants. These units were later called genes.

In the mid-1900s, scientists discovered that genes are made of DNA. In the 1970s, scientists learned how to change DNA with genetic engineering. Scientists also learned that problems with certain genes cause diseases. Muscular dystrophy, cystic fibrosis, and hemophilia are some genetic diseases-diseases caused by problems in genes. Today, scientists are looking for ways to cure genetic diseases by changing genes through a process called gene therapy.

Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are rub of black surfaces already, in the form of asphalt (柏油) roads?

Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.

The heat-colleetor is a system of connected water pipes. Most of them ran from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.

When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warning the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.

In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.

64. Which of the following is true according to the first two paragraphs?

A. Arian de Bondt got his idea from his boss.

B. Large, flat, black surfaces need to be built in cities.

C. The Dutch engineer's system has been widely used.

D. Heat can also be collected from asphalt roads.

65. For what purpose are the diving pipes used?

A. To absorb heat from the sun.

B. To store heat for future use.

C. To turn solar energy into heat energy.

D. To carry heat down below the surface.

66. From the last paragraph we can learn that __

A. some pipes have to be re-arranged in winter

B. the system can do more than warming up the building

C. the exchangers will pick up heat from the street surface

D. less heat may be collected in winter than in summer

67. What is most likely to be discussed in the paragraph that follows?

A. What we shall do if the system goes wrong.

B. What we shall do if there are no asphalt roads.

C. How the system cools the building in summer.

D. How the system collects heat in spring and autumn.

It’s such a happy-looking library, painted yellow, decorated with palm-tree stickers and sheltered from the Florida sun by its own roof. About the size of a microwave oven, it’s pedestrian-friendly, too, waiting for book lovers next to a sidewalk in Palm Beach Country Estates, along the northern boundary of Palm Beach Gardens.

It’s a library built with love.

A year ago, shortly after Janey Henriksen saw a Brian Williams report about the Little Free Library organization, a Wisconsin-based nonprofit that aims to promote literacy and build a sense of community in a neighborhood by making books freely available, she announced to her family of four, “That’s what we’re going to do for our spring break!’

Son Austin, now a 10^th-grader, didn’t see the point of building a library that resembles a mailbox. But Janey insisted, and husband Peter unwillingly got to work. The 51-year-old owner of a ship supply company modified a small wooden house that he’d built years earlier for daughter Abbie’s toy horses, and made a door of glass.

After adding the library’s final touches (装点), the family hung a signboard on the front, instructing users to ‘take a book, return a book,’ and making the Henriksen library, now one of several hundred like it nationwide and among more than 2,500 in the world, the only Little Free Library in Palm Beach County.

They stocked it with 20 or so books they’d already read, a mix of science fiction, reference titles, novels and kids’ favorites. “I told them, keep in mind that you might not see it again,” said Janey, a stay-at-home mom.

Since then, the collection keeps replenishing (补充)itself, thanks to ongoing donations from borrowers. The library now gets an average of five visits a day.

The project’s best payoff, says Peter, are the thank-you notes left behind. “We had no idea in the beginning that it would be so popular.”

One day, an expert in time-management was speaking to a group of business students. To make the point 1 , he used an illustration.
As he stood in front of the group, he said, “Okay, time for a quiz.” He then pulled out a wide-mouth jar and set it on the table. Then he    2   placed about a dozen fist-sized rocks, one by one, into the jar.
When the jar was filled to the    3   and no more rocks would fit inside, he asked, “Is this jar    4 ?” Everyone in the class said, “Yes.”
“Really?” Then he    5  under the table and pulled out a bucket of gravel（沙砾，石子），dumped some in and   6  the jar, causing pieces of gravel to work themselves down into the space    7  the big rocks. Then he asked the group the same question. “Probably not.” One of them answered. “Good!” he replied.
He reached under the table and    8   a bucket of sand. He started dumping the sand in the jar and it went into all the    9   left between the rocks and the gravel.    10   he asked the question. “No!” the class shouted. “Good!” Then he grabbed a can of water and began to pour it in    11   the jar was filled to the brim.
Then the expert in time-management looked at the class and asked, “What is the    12  of this illustration?” It is such a seemingly easy question that one   13   student raised his hand and said, “It is, however full your schedule is, if you try really hard you can always   14   some more things in it.”
“No,” the speaker replied, “The truth it teaches us is that you will    15   get them in at all if you don’t put the big rocks in first.    16   the big rocks in your life are, do things that you love and    17  for yourself. In your schedule if you value the little stuff then you’ll fill your life with    18   things and you will never have the real quality time you need to spend on the big, important stuff. So, tonight, or in the morning, when you are   19   on this short story, ask yourself what are the ‘big rocks’ in your life? Then put those in your    20   first.”
