Estimates ranged from 10 to 20 billion years old, a
10、 frustratingly large spread. But that was before the launch of the Hubble Space Telescope, named after the astronomer whose discovery 70 years ago began the quest to learn the universes age.Edwin Hubble found that the galaxies (星系) within the universe are speeding away from each other at a rate prop
11、ortional 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
12、Washington, D. C., announced the result of eight years of Hubble measurements: The universe is expanding at a rate of 21 kilometers per million light-years. That translates to an age of approximately 12 billion years for the universe. similar to the value for the oldest stare.“After all these years,
13、“ says Freeman. “we are finally entering an era of precision cosmology (宇宙论). Now we can more reliably address the broader picture of the universes 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 meas
14、urement to a distant galaxy that would make the universe 15 percent younger than Hubbles results.(分数:5.00)(1).What is the age of the universe according to the passage?(分数:1.00)A.Approximately 10 billion years old.B.20 billion years old.C.Approximately 12 billion years old.D.Not quite accurate now.(2
15、).Which of the following statements is NOT true according to the passage?(分数:1.00)A.Estimates of the universes age range from 10 to 20 billion years old, a frustratingly large spread.B.The quest to learn the universes age began 70 years ago by a famous astronomer named Edwin Hubble.C.The galaxies in
16、 the universe stand still, relative to each other.D.The new number of the universes age is not quite the last value.(3).What is the probable meaning of “pinning down“ in the Paragraph 2?(分数:1.00)A.Forcing.B.Discovering exact details about.C.Pressing.D.Knowing about.(4).What is the best title for the
17、 passage?(分数:1.00)A.Hubble MeasurementsB.Galaxies within the UniverseC.The Universes AgeD.Era of Precision Cosmology(5).We may learn from the passage that while entering an era of precision cosmology, _.(分数:1.00)A.we can pin down the exact value of the universes ageB.we can work out the universes si
18、zeC.we still cant know the exact age of the universeD.we can more reliably solve the broader picture of the universes origin, evolution, and destinyBPassage 2/BSurprisingly, there is a relationship between sea salt and the making of rain drops. Most of the water droplets that make up clouds are form
19、ed 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
20、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, bubble
21、s 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 salt collects water vapor from the air. The water vapor then condenses on the particle of salt. The moisture absorbed
22、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 (有作用的)in making the sin
23、gle rain droplet grow by coalescence with smaller droplets. Since low level clouds dont rise high enough to produce ice crystals as a source of condensation, it most likely is the salt particles that cause them to become rain clouds.(分数:5.00)(1).Rain clouds are characterized primarily by _.(分数:1.00)
24、A.dust particlesB.droplets that are uniform in sizeC.droplets that are large and smallD.bubbles(2).The passage implies that, in order for rain to fall, its necessary for water vapor to _.(分数:1.00)A.turn to ice crystalsB.collect on solid particles and condenseC.condense on salt particlesD.rise above
