2015淄博三模英语试题及答案(3)

The BBC’s Juliet Rix visited the frozen continent and asked herself if she should be there at all, causing potential problems to such a sensitive environment. Her tour guide admitted that all visitors leave a footprint and they all go to the same places, the accessible coastline, which is also where the penguins and seals go to raise.
But some people believe that if carefully controlled, tourism can be good for Antarctica. It has no native population and it needs advocates. Visitors to the icy continent might be ready to support and even to fund its preservation. And they're likely to engage in the discussion about global warming, which has led to the melting of glaciers.
According to Rix, guidelines are followed when you’re about to set foot in Antarctica and tourists have to disinfect（消毒）their boots to make sure no alien species are introduced.
And once on land, there's no eating or smoking. Rocks, bone fragments—nothing should be taken as a souvenir and nothing should be left behind.
Tourists fortunate enough to visit the Antarctic must be aware that this is not their home and keep their fingers crossed that future generations will also be able to enjoy such breathtaking views.
28. Who lives in Antarctica? 
A. 37,000 tourists.
B. The BBC's Juliet Rix.
C. A few scientists and animals. 
D. People in London and Paris.
29. Why can tourism be good for Antarctica? 
A. People can bring some animals into it.
B. People may take interest in the protection of it.
C. People can give advice to the native population.
D. People will go to the coastline to play with the seals.
30. What are the guidelines when you go on the shore?
A. You can leave rubbish on the shore.
B. You can smoke and eat on the shore.
C. You can take something as souvenirs.
D. You can help to protect the environment.
31. What is the author’s attitude towards the tourists going to Antarctica?
A. Positive.    B. Ambiguous.   C. Subjective.  D. Negative.
D
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 (海洋学家), 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 University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean. 
The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency’s Cryo-2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar (声波定位仪) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.
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.
David Sandwell says the map is a powerful tool for fisheries, those interested in protecting the environment and for oil exploration.
“The petrol exploration industry is interested in how to reconnect the continents, bring them back together tectonically so you can map the basins on one continental edge—say, Africa—and use that to establish where the similar basin would be on the other continental edge in South America.”
If scientists know that information, they may be able to find oil fields. The new data also will help scientists improve their estimates of ocean depths. This information can help ships travel safely and improve military operations and scientific projects worldwide. 
Mr. Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides.
32. Which one is not mentioned about the benefits brought by the new map?
A. Fisheries.     B. Scientific projects.
C. Ship manufacture. D. Oil exploration.
33. What can we know about the new map?
A. It shows where earthquakes will happen.
B. It will be helpful to industry and governments. 
C. It is three times as detailed as the old one years ago.
D. It shows the sea floor as it has ever been seen before.
34. The text is likely to appear in _________.
A. a newspaper    B. an advertisement
C. a science magazine    D. a finance report
35. Which of the following can be the best title for the text?
A. The detailed picture of the oceans
B. Underwater mountains and places
C. More discoveries about the oceans
D. Scientists create new maps of ocean floor

How to Protect Yourself from Hackers Online
An increase in cyber-attacks (网络攻击) makes the Internet seem like a scary place these days. How can individuals protect or make it more difficult for hackers to access their information? Here are several tips that can help you protect against cyber-attacks:
   36  
Hard passwords include upper and lower case letters, numbers and special characters. They should be at least eight characters in length. They should also not spell out words easy for hackers to find, like your pet's name or the name of a family member.
