Section A

Directions: In this section, you will hear 10 short conversations. At the end of each conversation, a

Part II Reading Comprehension (35 minutes)

Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.

Passage 1

Questions 21 to 25 are based on the following passage.

For years astronomers struggled to calculate the age of the universe. Estimates ranged from 10 to 20 billion years old, a frustratingly large spread. But that was before the Hubble Space Telescope, named after the astronomer whose discovery 70 years ago began the quest to learn the universe’s age.

Edwin Hubble found that the galaxies (星系) within the universe are speeding away from each other at a rate proportional to their distance. That expansion rate ——the Hubble constant (常数)—— is the key to calculating the age and size of the universe. But pinning down the constant requires precise measurements of the distances to far-flung galaxies.

In May, a team led by Wendy Freeman of the Carnegie Institution of Washington. D.C, announced the result of right years of Hubble measurements: The universe is expanding at a rate of 21 kilometers per million light-years, that translates to an ape of approximately 12 billion it-are for the universe, similar to the value for the oldest stare.

\宇宙论). Now we can more reliably address the broader picture of the universe's origin, evolution and destiny.\

Is the new number the last word? Not quite. In June, astronomers using a large array of radio telescopes reported a measurement to 3 distant galaxies that would make the universe 15 percent younger than Hubble' s results.

21. What is the age of the universe according to the passage? A) Approximately 10 billion years old. B) 20 billion years old.

C) Approximately 12 billion years old. D) Not quite accurate now.

22. Which of the following statements is NOT true according to the passage?

A) Estimates of the universe's age range from 10 to 20 billion years old, a frustratingly large spread. B) The quest to learn the universe's age began 70 years ago by a famous astronomer named Edwin Hubble.

C) The galaxies in the universe stand still, relative to each other. D) The new number of the universe's age is not quite the last value.

23. What is the probable meaning of “pinning down” in the Paragraph 2? A) Forcing. B) B) Discovering exact details about.

C) Pressing. D) Knowing about.

24. What is the best title for the passage? A) Hubble Measurements

B) Galaxies within the Universe C) The Universe’s Age

D) Era of Precision Cosmology

25. We may learn from the passage that while entering an era of precision cosmology. A) we can pin down the exact value of the universe’s age B) we can work out the Universe’ s size

C) we still can't know the exact age of the universe

D) we can more reliably solve the broader picture of the universe’s origin, evolution, and destiny.

Passage 2

Questions 26 to 30 are based on the following passage.

Surprisingly, there is a relationship between sea sail and the making of rain -drops. Most of the water droplets that make up clouds are formed around small, solid particles. In order to fall as rain, the cloud droplets have to increase in size. Clouds from which rain does not fall have droplets that are fairly uniform in size. Clouds that produce rain have some droplets that are much larger than others.

The production of rain depends on the presence of the large droplets that grow in size by coalescence (a fusing together). There is evidence to support the theory that a particle of sea salt serves as the nucleus (核，核心)or center, around which the larger droplets form. Most of the sea salt probably enters the atmosphere from bubbles that form on the surface of the sea. When the bubbles break, a tiny, even microscopic, droplet of salt water is cast into the air. Once in the atmosphere, the microscopic piece of sail collect water vapor from the air. The water vapor then condenses on the particle of salt. The moisture absorbed by the salt particles dissolves the salt, thus leaving only a slightly salty cloud droplet.

Cloud droplet, formed from condensation of salt particles of dust particles. The reason is that salt particles are usually larger than dust particles. Their larger size is instrumental (有作用) making the single rain droplet grow by coalescence with smaller droplets. Since low-level clouds don't rise high enough to produce ice crystals as a source of condensation, it most likely is the salt particles that cause
