【題目】Tuvalu, a tiny country in the Pacific Ocean, has asked for help as it fears it will be swallowed up by the sea. Storms and huge waves are a constant threat and none of Tuvalu’s nine little islands is more than five meters above sea level. Salt water is already entering the country’s drinking water supply, as well as damaging plants that produce fruit and vegetable. 1

2 Venice(威尼斯), a historic city in Italy best known for its canals, has sunk about 24 cm over the past 100 years. Experts say that it will have sunk another 20 cm-50 cm by 2050. A century ago, St. Mark’s Square, the lowest point in the city, was flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, Tuvalu’s rising sea level is caused by global warming.

The average global temperature has increased by almost 0.5 centigrade degree over the past century; scientists expect it to rise by extra 1-3 degrees over the next 100 years.

Warmer weather makes glaciers(冰川)melt, adding more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10 cm-25 cm in the last 100 years.

3

Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.

Many scientists believe that, if the warming is not stopped, there will be huge climate change. 4

5 , the sea will swallow up millions of homes and the world will be flooded with "climate refugees" looking for somewhere to live.

A. The main cause of global warming is human pollution.

B. Should this come true

C. Without urgent help, the country’s days are numbered.

D. But Tuvalu is not the first place to face sinking into the sea.

E. The sea level could rise by one meter this century.

F. People face a lot of pollution.

G. Much has been done about our planet.

【題目】The National Geographic Channel has unearthed a time capsule (時(shí)光寶盒) buried by late Apple chairman and co-founder Steve Jobs thirty years ago.

The time capsule was buried in Aspen, Colorado, in 1983, shortly after Jobs attended the International Design Conference being held in that city. Organizers called the device the Aspen Time Tube and contributed items like Rubik's cubes(魔方) and some iconic music. Jobs added his own items to the capsule, including the " Lisa" ( also known as an "Apple" ) mouse" he used for his presentation at the conference.

Younger readers may not recognize the name but the Lisa Apple mouse was one of the first commercial mice released to consumers. The mouse was specially designed for the Apple Lisa computer. It's also the first personal computer to offer users a graphical user interface(圖形用戶界面)

Initially, the plan was to dig up the time capsule in the year2000, but organizers forgot its exact location. Recently, they brought in researchers working with the National Geographic Channel show Diggers to find the device. Eventually they came across the 13-foot-long, 1.5-foot-diameter tube. Inside they found a lot of 1980s artifacts(人工制品)that are still being catalogued.

“When the end came off, literally things just poured out.” noted Diggers host Tim Saylor "There must be literally thousands of things in there.”

“They had the foresight to put a bunch of stuff in plastic bags." Saylor said. “I could see at least a dozen plastic bags and other items. But I know for sure there got to the photographs in there. /span>People had hand-written things on the back of the photographs, so there will be some really interesting things inside.”

Among the artifacts researchers expect to discover inside: a Steve Jobs speech in which the Apple visionary outlines his predictions for future technologies. We should know more about the researchers, discoveries once the Diggers program airs this fall.

1Which of the following is true about the Lisa mouse?

A. The mouse was the first commercial one for consumers.

B. The mouse was created only for the Apple Lisa computer.

C. The mouse was buried in Aspen, Colorado for two decades.

D. The mouse was invented after the International Design Conference.

2Why wasn't the time capsule dug up in 2000?

A. Because it was not the time set by Steve Jobs.

B. Because it could not be accurately located.

C. Because organizers forgot its precise shape.

D. Because the local government didn't approve.

3From the passage we can infer that_______.

A. there were some special photographs found-inside the time capsule

B. a Steve Jobs speech with future predictions was found inside the cap

C. Steve Jobs predictions for future technologies have come true

D. more about the capsule will be discovered in the Diggers program

4The best title for the passage might be _______.

A. The "Lost" Steve Jobs Time Capsule

B. The Mystery of Steve Jobs Speech Solved

C. Steve Jobs' 1983 Time Capsule Recovered

D. Co-founder & Former Apple CEO Steve Jobs
