阅读短文,从每题所给四个选项（A、B、C和D）中选出最佳选项。

Steel, concrete(混凝土) and glass are the usual materials in any skyscraper. But more high buildings are now using wood.

In the last four years, Australia, Norway, England and Canada have all built wooden skyscrapers. The latest one is in Sweden, a new, 19-storey wooden hotel called "Sida vid Sida" (Side by Side).

Why are wooden skyscrapers being chosen ahead of concrete ones? Let's find out.

Is it strong enough?

Wood has been used in many Chinese buildings for thousands of years, but is it strong enough for skyscrapers?

"There's a lot of new materials made out of wood that are able to build big buildings," material expert Dr Michael Ramage told CNN when he was interviewed.

Architects (建筑师)have done thousands of experiment to make sure it is. They place layers of wood across one another coated with special glue to create very strong material.

Wood also lasts a long time and doesn't break down if it is well looked after. The examples include the rooftops of Beijing's Forbidden City and some 700-year-old houses in England.

Ramage also said on the internet that bamboo could be cut in special ways to make it even stronger than normal wood.

Won't it catch fire?

Wooden buildings sound dangerous when it comes to fire. But experts say they may be safer than concrete ones if there is a fire.

"Wood doesn't burn in the way the public imagines," Ramage said. Very small pieces of wood catch fire easily, but very big pieces of wood are quite hard to set on fire, he said.

（1）、In Sweden, the main building material of "Sida vid Sida" is _____.

A、steel B、concrete C、glass D、wood

（2）、The underlined word skyscraper in the first paragraph means ___________.

A、wooden buildings B、wooden hotel C、high buildings D、Beijing's Forbidden City

（3）、What is CNN?

A、It's the name of the interviewer. B、It's an expert. C、It's a program on the internet. D、It's an Architect.

（4）、According to the last paragraph, we learn that ____.

A、wooden buildings aren't safer than concrete ones B、small pieces of wood are hard to set on fire C、The public may have a misunderstanding of wood burning. D、wooden buildings are strong.

（5）、We can read the passage in _____.

A、a science magazine B、an art book C、a diary D、a guidebook

（6）、What does the story mainly talk about?

A、Different building materials. B、Wood as a building material. C、Architects' worries about wood D、The architect's view on building materials.

    Our nearest neighbor is the moon. In the sky, the moon and the sun seem to be of the same size because the moon is much nearer.
The moon makes the tides—the changes in the level of the sea. The moon and the sun together pull the sea. In some parts of the world, the difference between "high tide" (when the sea is very near to the land) and " low tide" (when the sea is far away from the land) is very big. This is very important for ships.
    The moon is very different from the Earth. Gravity on the moon is six times weaker than that on the Earth. There isn't any air. During the day, it is very, very hot but at night it is very, very cold. Nothing can live on the moon.
    If the moon goes between the Earth and the sun, we have an eclipse of the sun(日食) . The moon stops the light from the sun and we have night in the day.
    If the Earth goes between the moon and the sun, we have an eclipse of the moon. The moon goes into the shadow(影子) of the Earth and it disappears for a few minutes.

    What is color? Why do some of the things around us look red, some green, others blue?
    Colors are really made by deflected (反射) light. We see color because most of the things reflect light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn't reflect any light, it is black.
    Some of the light is reflected and some is taken in (吸引) and turned into (变成) heat (热能).The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.

    What will the house of the future look like? Architects (建筑师) believe that there are all possibilities. The only thing for sure is that the house will be as green as possible.
    The tree house
    Many architects in the world would like to build a “tree house.” Like a leaf, the surface (表面) of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” of the house is deep under the ground.
    The lizard (蜥蜴) house
    Like a lizard, changing color with the weather is the most important design of a lizard house. When it's in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.
    Meals at home
    It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.
Learning from the past
    Looking to the future isn't the only way to be green. Sometimes, ancient techniques (古老的技术) can also help cut down energy use. For example, a chimney can be a useful air conditioner because it is easier for hot air to flow out at the chimney.

Do you know how many pandas there are in the world? World Wildlife Fund (WWF) has spent four yours counting pandas in the world. It says there are 1,590 now. In the 1980s, there were only 1,100.

So we may say that pandas are lucky because people around the world love them and are trying their best to help them. However, we also say that pandas are unlucky because they are still facing a lot of problems now.

Pandas are not good at making babies. Even in the wild, scientists have found that female pandas give birth only every 28 months. That's why the number of pandas goes up so slowly.

Pandas need bamboos for food, but bamboo dies every 10 to 100 years. It can take up to 20 years to provide(提供) food for pandas. When bamboo dies, pandas have to move to other areas. In the past, this was easy. However, the number of people keeps growing, people cut down more forests and built more villages. It's more difficult for pandas to find bamboos and homes than before.

In the past years, WWF made great efforts to protect pandas. And some Chinese scientists are also always trying to find ways to help pandas.

There are world records at the Olympic Games. But what are the word records in animal kingdom?

The largest and heaviest animal on earth is the blue whale. It weighs between 110 and 120 tons. Its heart is the size of a Mini Cooper, It's got the biggest mouth in the world as well. About 100 people can fit inside it. But it doesn't eat people! In fact, the biggest thing it can eat is the size of an apple.

The giraffe is smaller than the blue whale but it is also a record breaker. It's the tallest living land animal. It's got the longest neck-about 2 metres long, and it's got the longest legs-about 1.8 metres long. Drinking is difficult, but eating from the top of trees is easy! And its tongue is 50 c m long!

The most dangerous animal in the world isn't a lion or a bear. It's an insect! The mosquitoes (蚊子) that carry malaria kill over 1 million people a year. After that, the most dangerous animal is the venomous snake. They kill 50,000 to 125,000 people a year.

Don't be too surprised if you see a car going down the road without a driver in Beijing these days. It might be one of Baidu's self-driving cars. Last month, Baidu was granted (授予) a license to test its self-driving cars on open roads in Beijing, China Daily reported.

Self-driving cars have been in development since 2010, when Google announced that it was making such cars. Since then, companies like Tesla, Uber and Baidu have been working to produce and test their own self-driving cars.

Self-driving cars are expected to revolutionize (革命) the way we get around. They are safer and more environmentally friendly than regular cars. They can remove the stress of driving and allow disabled or blind people to get around more easily.

But self-driving cars have their own flaws (缺陷) as well. In one test, researchers pointed a laser pointer (激光棒) at the car's sensors (传感器) while it was moving. The car mistakenly thought that the laser beam was in its way and slowed down or changed direction. Flaws like this could be used by people to trick self-driving cars, according to the Guardian.

The software that is used to direct the cars may not be safe enough, reported Live Science. It may crash (崩溃). When we use our computers or smart phones, they sometimes crash without any reason. But if this happened to a self-driving car, the results could be deadly. Improvements to the software could be a solution to this problem.
