With eight bloodshot eyes fixed on a flying object, the pains of a two­year project were about to bear fruit.

It was Wang Hongyi's first test flight of an unmanned aerial vehicle (UAV)designed and assembled (组装) with his teammates from the Aero­Sport Club (航模队) at Shanghai Jiaotong University.

Wang is a senior mechanical engineering and automation major. He has been a plane model fan since childhood. As a freshman, he spent two nights building a model aircraft and took it to the sports field just for fun. Wu Junqi, the coach of Shanghai Jiaotong University's Aero­Sport Club, spotted Wang and told him his model was outdated.

“I was a little angry, so he took me to the lab，”says Wang. He was immediately drawn to the modern equipment and decided to join the club. As a technology fan, Wang spends most of his spare time in the lab. “He loves what he's doing, so he can stand the loneliness of doing research that others seldom have the persistence to carry out.” says coach Wu.

When Wang and his teammates were building UAV, they lived together in the lab. “We tried to spend as much time together as possible because there were thousands of problems that needed to be solved.”  Wang says. They didn't even have time to celebrate when the first test flight of the UAV went well. “We needed to list the problems that occurred during the flight and analyze them to find solutions.” he says.

“Our UAV isn't finished yet, but there are many design projects and people with similar interests waiting for me.”  Wang says. “The UAV is just the beginning, not the end of my aircraft journey.”

1.Why did Wang succeed in doing the research?

A.He majored in mechanical engineering and automation.

B.He had a good coach and wonderful teammates.

C.He loved what he did and would stick to it.

D.He was highly thought of by Wu Junqi.

2.What does the writer want to do by writing the passage?

A.Encourage students to learn from Wang Hongyi.

B.Tell readers about UAV development in China.

C.Inform readers about Wang Hongyi and his UAV.

D.Call on readers to do what interests them.

3.What message does Wang Hongyi's story convey to us?

A.Nothing is difficult if you put your heart into it.

B.Two heads are better than one.

C.Interest is the best teacher.

D.Actions speak louder than words.

As Internet users become more dependent on the Internet to store information, are people remembering less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.

In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know how the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.

In another experiment, the researchers gave people facts to remember, and told them where to find the information on the computer. The information was in a specific computer folder (文件夹). Surprisingly, people later remembered the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called “transactive memory (交互记忆).”

According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn't mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

4.The passage begins with two questions to         .

A.introduce the main topic　 B.show the author's attitude

C.describe how to use the Internet D.explain how to store information

5.What can we learn about the first experiment?

A.The Sparrow's team typed the information into a computer.

B.The two groups remembered the information equally well.

C.The first group did not try to remember the information.

D.The second group did not understand the information.

6.In transactive memory, people         .

A.keep the information in mind

B.change the quantity of information

C.organize information like a computer

D.remember how to find the information

7.What is the effect of the Internet according to Sparrow's research?

A.We are using memory differently.

B.We are becoming more intelligent.

C.We have poorer memories than before.

D.We need a better way to access information.

Windows 8, apart from Windows 95, is the biggest surprise and the only version of Microsoft's operating system that has been changed from the core (核心) when compared to its former one. However, a recent study has shown that under 20% of business owners would be willing to upgrade to the new version of Windows. The reason for this remains to be discussed and debated, and we will try to throw light on this research by providing you with some of the most common advantages and disadvantages of Windows 8.

Generally speaking, there are a great number of plus sides related to upgrading from Windows 7 to Windows 8.

Speed—This is the biggest advantage to mention. Boot time has been reported to be up to nine times shorter than that with Windows 7.

New passwords—Instead of typing your passwords, Windows 8 will let you use gestures on your favorite photos to enter your password. This is not only practical but also extremely cool!

Windows 8 experience—Apart from computers, Windows 8 will be used on all devices, including smart phones, tablet PC's and so on. Also, owing to the fact that it has been specifically designed with touch screen users in mind, Windows 8, besides using keyboard and mouse, will offer a whole new user experience.

However, there are still some disadvantages.

The first one that has to be mentioned is that there is no Start Menu from Windows. Yes, there is no Start button in the lower left corner, and this might be a real puzzle of many Windows users. Also, many users have had a problem to get used to the new interface (界面) introduced by Windows 8. The biggest problem that is worth noticing is that Windows 8 was originally designed for touch screen users, and this may have a bad effect on desktop users who have gotten used to doing everything with the help of their keyboard and mouse.

8.What does “plus sides” in Paragraph 2 probably refer to?

A.Math symbols. B.Strengths.

C.New rules. D.Messages.

9.According to the text the greatest advantage of Windows 8 is its         .

A.complex passwords B.high speed

C.unique experience D.new interface

10.From the text we can learn that Windows 8         .

A.no longer requires a password

B.was upgraded from windows 95

C.will be popular with desktop users

D.can be used on more than computers

11.Many Windows 8 users face the problem that         .

A.start Menu is hidden in the lower left corner

B.they have to use fingerprints instead of button

C.keyboard and mouse can't be used any longer

D.they don't get accustomed to the new interface

We know more about the surface of the planet Mars than we know about what is at the bottom of Earth's oceans.

Until recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers, industry and governments.

The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the Scripps Institution of Oceanography at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean. He spoke to VOA on SKYPE.

“The way we're doing that is to use a satellite altimeter (高度计), a radar to map the topography (地貌) of the ocean surface. Now that seems sort of strange that you'd map the topography of the ocean surface when you really want to get at the sea floor. But, the ocean surface topography has these bumps and dips due to gravitational effects that mimic what's on the sea floor.”

The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency's Cryo­2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason­1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.

“That enables us to look at smaller­scale features and also features that are buried by sediments in the ocean basins.”

The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.

In one place, three mountain ridges join at the same area. Huge tectonic (构造的) plates can be seen clearly there.
