第一篇
Black Holes
Most scientists agree that black holes exist but are nearly impossible to locate. A black hole in the universe is not a solid object, like a planet, but it is shaped like a sphere (球體). Astronomers(天文學(xué)家) think that at the center of a black hole there is a single point in space with infinite (無限的) density (稠密). This single point is called a singularity (奇點(diǎn)). If the singularity theory is correct, it means that when a massive star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point.
Anything that crosses the black hole is pulled in by its great gravity.
Although black holes do exist, they are difficult to observe. These are the reasons.
• No light or anything else comes out of black holes. As a result, they are invisible to a telescope.
• In astronomical terms, black holes are truly. For example, a black hole formed by the collapse of a giant star would have an event horizon (視界) only 18 miles across.
• The nearest black holes would be dozens of light years away from Earth. One light year is about 6 trillion (萬億) miles. Even the most powerful telescopes could not pick out an object so small at such a great distance.
In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still answers to be found, however, so black holes remain one of the mysteries of the universe.

第二篇
The Race into Space
American millionaire Dennis Tito will always be famous. He was the first tourist in space. "Ispent 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 I 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 worded. 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 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 Califomi, 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 for space flight. He says that the chances of dying are about 1 in 500. Because of this it may administrator time before space tourism really takes off. You might be able to go up, but will you come down?

答案與解析
第一篇
1. A。題干：黑洞是太空的一部分。利用space回到原文定位，很容易找到文中首段第三句和第二段第一句都有一致的信息。因此選擇A。
2. A。題干：黑洞是存在的但是不容易被觀察到。題干中的關(guān)鍵詞為difficult，用它回到原文定位，在首句能找到difficult的近義詞impossible。首句的意思是，黑洞確實(shí)存在，但很難定位(locate)，與題意信息相符，故選A。
3. B。題干：黑洞的中心是空的。用中心詞the center來定位，首段倒數(shù)第二句有答案：其中心不是一個(gè)洞，由此證明中心不是空的，因此選擇B。
4. C。題干：兩顆大星體的相互吸引產(chǎn)生重力。用數(shù)字two和中心詞gravity(吸引力)回到原文定位，文章并沒有相關(guān)信息。故選擇C。
5. c。題干：太陽是宇宙最重的星體。用中心詞the sun回到原文定位，文章并未提及與太陽相關(guān)的`信息。因此選擇C。
6. B。題干：離我們最近的黑洞有幾百光年遠(yuǎn)。用中心詞nearest定位，原文倒數(shù)第二段有相關(guān)信息。但原文說的是“最近的黑洞離地球有幾十光年(dozens)遠(yuǎn)”，而不是
“hundreds”。因此選擇B。
7. A。題干：Hubble太空望遠(yuǎn)鏡幫助人們了解宇宙的本質(zhì)。由專有名詞the Hubble Space Telescope回到原文定位，不難發(fā)現(xiàn)相關(guān)信息在最后一段。原文信息與題干信息是一致的。
故選A。
第二篇
1. A。題干：Dennis Tito是第一位太空旅行者。由專有名詞Dennis Tito定位，這是第一題，因此回到文章第一段，找到相關(guān)旬。第一段介紹了美國(guó)富豪Dennis Tito作為第一位太空游客的經(jīng)歷。因此，本題的答案為A。
2. B。題干：Mark Shuttleworth是來自美國(guó)的工程師。用人名Mark ShuRleworth回到原文定位，文章第三段指出Mark Shuttleworth是一位南非商人。因此，本題與文章內(nèi)容不符。
答案為B。
3. c。題干：Tito和Shuttlewolth都攀登過珠穆朗瑪峰。文章沒有涉及二人攀登珠穆朗瑪峰的信息。因此答案為C。
4. A。題干：太空冒險(xiǎn)活動(dòng)有大約100名顧客在等著太空旅行。用數(shù)字100回到文中定位，發(fā)現(xiàn)文章第四段第二句提到：“這家公司已有一百多人在等待飛往太空的名單上登記。”
本句與文章內(nèi)容相符，因此，答案為A。
5. B。題干：太空探險(xiǎn)公司已經(jīng)擁有一架宇宙飛船。由中心名詞spaceship回到文章定位，文章第四段最后指出：“而攜帶他們的宇宙飛船還沒出現(xiàn)。”因此，答案為B。
6. A。題干：IOS將從Tonga發(fā)送旅客進(jìn)入太空。用地名Tonga回到原文定位，文章第六段談到了太空軌道傳送公司的計(jì)劃，指出進(jìn)入太空的旅行將從Tonga(湯加群島)的一個(gè)島嶼出發(fā)。本題與文章內(nèi)容相符。因此答案為A。
7. A。題干：Bill Readdy認(rèn)為太空飛行是非常危險(xiǎn)的。用人名Bill Readdy回到原文定位，文章最后一段提到太空旅行依然是非常危險(xiǎn)的，接著Bill Readdy還指出太空旅行的死亡率是1/500，正是由于這一點(diǎn)，也許太空旅行真正啟程尚需時(shí)日。因此可知本題與文章內(nèi)容相符，故答案為A。
