【題目】 When it comes to long-distance space travel, the biggest problem is that spaceships can only get as far as the fuel onboard allows. In 1964, a British writer Clarke came up with the idea of “solar sailing” in his science fiction. He wrote of large, mirror-like sails that collect power from the sun and free spaceships from the limitation of fuel.

This sci-fi idea was first successful brought to reality in 2010 by Japan’s IKAROS satellite. Ever since then, the technology has improved mission by mission, with the latest being NASA’s Advanced Composite Solar Sail 3(ACS3). NASA has recently announced that it’s going to team up with Lithuania’s satellite-building company NanoAvionics to test its new sail in Low-Earth Orbit.

To many, a solar sail may look like a giant solar panel, but it actually works very differently. While solar panels take in energy from the sun and change it into power, solar sails use Photons given off by the sun to create direct power. Besides, solar panels are big and heavy to carry, while solar sails are just the opposite.

According to Abbott, the CEO of NanoAvionics, the upcoming Low-Earth Orbit trial with NASA, if successful, will be followed with deep-space missions that involve larger solar sails. These are ideal for low-cost and long-distance space travel because fuel will no longer be a problem.

“It started as a sci-fi dream,” Popular Mechanics reporter Jennifer Leman wrote. “Now it could be the future of space flight.”

【1】What can we say about solar sailing according to the first two paragraphs?

A.It was widely used in space travel.

B.It was tried by IKAROS satellite.

C.It was from the creative idea by Clarke.

【2】Which of the following words best describe solar sails compared with solar panels?

【3】What does the underlined word These in paragraph 4 refer to?

【4】What is the best title for the text?

A.Solar Sail: the Latest Technology

B.Solar Sail: from Dream to Reality

C.Solar Sail: a New Kind of Spaceship

【題目】閱讀下面短文，從各題所給的A、B、C三個(gè)選項(xiàng)中選出最佳選項(xiàng)。

Have you ever heard “You never get a second chance to make a first impression(印象)?” It may sound like an unusual piece of advice, but it is true—the first impression someone has of you when meeting you for the first time will probably influence how that person reacts to you in the future.

What is even more interesting is that the brain takes in all the information to create that first impression in about three seconds. When you meet someone for the first time, by the time you have said your name or shaken hands, the other person has already formed(形成) an opinion about the kind of person you are.

So how do you make a good first impression? Being polite and being well dressed is very important. However, the most important way of making a good first impression is your face. Smiling almost always leaves a positive(積極的) impression on people, especially those who do not know you. Most people, generally speaking, are ready to smile back when they are smiled at.

What’s more, smiling and being positive helps you to know and get a better understanding of new things. This means that you can possibly be friendlier to people you do not know and be more creative and able to solve problems more quickly. So if you ever need a reason to be happy, think about the wonderful people you might meet—and impress—with a cheerful smile.

【1】What do the underlined words “reacts to” in Paragraph 1 probably mean?

A.Treats.B.Changes.C.Describes.

【2】What can we learn about the first impression from Paragraph 2?

A.It comes very quickly.B.It is very strange.C.It is very interesting.

【3】What is the most important to make a good first impression?

A.Shaking hands.B.Dressing nicely.C.Smiling.

【4】What can be learned from the last paragraph?

A.Information helps you solve problems.

B.There are many reasons to be happy.

C.Being positive helps you find a way out.

【5】What would be the best title of the text?

A.The importance of the first impression

B.The ways of leaving deep impressions

C.The reasons for leaving impressions
