1、The Race into SpaceAmerican millionaire Dennis Tito will always be famous. He was the first tourist in space. "I spent sixty years on Earth and eight days in space and from my viewpoint, it was two separate lives," Tito explained. He loved his time in space. "Being in space and looking back at earth is one of the most rewarding experiences a human being can have."This kind of experience isn\'t cheap. It cost $ 20 million. However, Tito achieved his dream, so he was happy. "For me it was a life dream. It was a dream that began when didn\'t have any money," he told reporters.On 30 April 2002, Mark Shuttleworth became the world\'s second space tourist. Shuttleworth is a South African businessman. At the age of twenty - eight, he also paid $ 20 million for the eight - day trip.Both Tito and Shuttleworth bought their tickets from a company called Space Adventures. The company has around 100 people already on their waiting list for flights into space. The spaceship to take them doesn\'t exist yet.Many of the customers are people who like adventure. They are the kind of people who also want to climb Mount Qomolangma. Other customers are people who love space. However, these people are worried. Because it’s so expensive, only very rich people can go into space. They want space travel to be available to more people.That day may soon be here. Inter Orbital Systems (IOS) plans to send up to four tourists a week into space. The tours will depart from an island in Tonga. The company promises a package that includes forty-five days of astronaut training in Russia and California, seven days in space, and a vacation in Tonga, for $2 million.However, space flight is still very dangerous. Bill Readdy is NASA\'s deputy assistant administrator for space flight. He says that the chances of dying are about 1 in 500. Because of this, it may take time before space tourism really takes off. You might be able to go up, but will you come down?Space Adventures already has a spaceship.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题有一定难度，本题又回到第四段出题，考生需要从第四段寻找答案依据。带着题干提示词Space Adventures迅速回到文章定位。第四段最后一句谈到，运载他们的太空飞船还不存在，所以本题错误，答案是B

2、RobotsThe most sophisticated (先进的) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接), spray-painting and assembling components.In Britain robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan. The reliability of robots is measured in their MTBF or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small .sample.The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. One programmed robots can work more accurately and consistently than humans, who can get tired and bored.Paragraph 6 ________.【单选题】

A.Ongoing Research

B.Extension of Use

C.Robot Heroes

D.Greater Reliability

E.Falling Demand

F.Hidden Danger

正确答案:D

答案解析:第六段没有主题句，该段主要提到了提升机器人可靠性的方法。D选项Greater Reliability（更高的可靠性）与其表达一致，故D为正确答案。

5、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a major contributor to the planet\'s increasing temperature rise or global warming. Molecule for molecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun\'s heat and warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a major factor of causing the global warming.Methane is ____ to the intensifying greenhouse effect.【单选题】

A.one of tire major contributors

B.the ever-increasing atmospheric concentration of greenhouse gases

C.big and hefty cows

D.livestock\'s normal digestion process

E.how to cut down the cattle population

F.big industries and gas-guzzling vehicles

正确答案:A

答案解析:选A的依据在第1段的第2句和最后一句。
