—I think so, he is so great.

A．for; to save        B．of; to save         C．for; to saving       D．of; to saving

 

【答案】

B

【解析】

試題分析：it可指代下文內(nèi)容做形式主語，其主要有兩種形式：1、It's + 形容詞 + of + sb + to do sth.這個(gè)句型，形容詞一般為sb的所具有的一種品質(zhì)性格。2、It's + 形容詞 + for + sb + to do sth.這個(gè)句型,形容詞不是sb所具備的品質(zhì)性格。句意：為了救落水的孩子失去了生命，最美麗的老師楊向明是無私的。不定式作目的狀語表示具體的將要進(jìn)行的動(dòng)作，故選B。

考點(diǎn)：it做形式主語的用法

點(diǎn)評：it是人稱代詞,在句子中可以做形式主語,形式賓語,這是經(jīng)�？疾斓膬�(nèi)容,平時(shí)應(yīng)注意總結(jié),加強(qiáng)練習(xí).

Thousands of years ago, people didn’t know that the Earth moved. They thought the sun really did move across the sky. The Greek god Helios was said to drive the sun around the sky with his chariot（戰(zhàn)車）. But now, these ideas have all changed. Nowadays, it is the sun that drives our “chariot” around the sky.

So what does all this mean? Well, quite simply, there is now a plane （or “chariot”） that is powered by the sun. It has special parts in its wings. These parts absorb power from the sun. They absorb so much power that they can carry on flying at night. In the Greek myths（希臘神話）, Helios had to take a break at night. It seems we’re finally even more efficient than the gods themselves.

This plane is called Solar Impulse （“太陽驅(qū)動(dòng)”號）. It will fly across the US in May. This is very important for the future of the world.

So why is solar energy so good for us? Well, other kinds of energy cause a few problems. If you live in China, you’ve probably noticed the pollution. This is caused by burning coal or gas to make energy. The heat and chemicals（化學(xué)制品）from this make things work. But if we use the heat from the sun, we don’t have to burn anything, and there’s no pollution.

Solar energy is not all there yet. It needs to be improved. But the best thing about it is that, unlike coal and gas, it doesn’t run out. Solar Impulse could keep flying forever. Well, actually, the sun will run out too, one day, but not for another 5 billion years. That’s a pretty long flight.

1.What does “chariot” really refer to in the last sentence of Paragraph 1?

A．The Earth.         B．The Greek god.     C．Solar Impulse.      D．Birds.

2.Which of the following is TRUE of Solar Impulse?

A．It can only fly at night.                    B．It has already flown across the US.

C．It is powered by the sun.                  D．It needs gas to work.

3.In the passage, what is mentioned as the cause of pollution in China?

A．Overpopulation.                        B．Burning coal or gas.

C．Using solar energy.                      D．Heavy traffic.

4.What does the writer mean by “That’s a pretty long flight”?

A．It takes a lot of time to get Solar Impulse going.

B．Solar Impulse moves very slowly.

C．Solar Impulse will be in use for a long time.

D．Solar Impulse has a long way to go to take the place of the sun.

5.The passage is most probably taken from___________.

A．a(chǎn) Greek myth      B．a(chǎn) science fiction     C．a(chǎn) story-book       D．a(chǎn) science magazine

In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.

Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.

Until now, even the most advanced (先進(jìn)的) robot was almost certain to break down when it was damaged (毀壞). That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed. 

To deal with this problem, the scientists put eight motors (發(fā)動(dòng)機(jī)) and two sensors (傳感器) that read how the machine is working. They all give signals to the machine’s software. Using this information, the computer can then figure out the machine’s shape at any moment.

The new technology is a big advance in robot-making, scientists say, and it’s far from scary. It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.

“It has been difficult to design robots that can work well when the environment changes or when it’s damaged,” says Olaf Sporns of Indiana University in US. “With this work, we are nearer to solving this problem.”

1.Why do robots easily break down when they are damaged?

A．They cannot repair themselves.

B．The computer has changed a lot.

C．They have no computers inside.

D．The computer cannot work if the robot changes.

2.The new technology(技術(shù)) allows the robot to        .

A．keep working after being damaged

B．tell people where it is

C．do house work for humans

D．remember a lot of information

3.The underlined word “them” in Paragraph 5 refers to       .

A．sensors           B．robots            C．scientists          D．a(chǎn)rms and legs

4.How do the sensors in the robot work?

A．They can replace the computer when it’s broken.

B．They help the computer learn the robot’s condition.

C．They can find out where the damage comes from.

D．They can send signals to the person who uses the robot.
