Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

For a time, the Hubble telescope was the brunt of jokes and subject to the wrath of those who believed the U.S government had spent too much money on space projects that served no valid purpose. The Hubble was sent into orbit with a satellite by the Space Shuttle Discovery in 1990 amid huge hype and expectation. Yet after it was in position, it simply did not work. Because the primary mirror was misshapen, it was not until 1993 that the crew of the Shuttle Endeavor arrived like roadside mechanics, opened the hatch that was installed for the purpose, and replaced the defective mirror with a good one.

Suddenly, all that had originally been expected came true. The Hubble telescope was indeed the “window on the universe”, as it had originally been dubbed. When you look deep into space, you are actually looking back through time, because even though light travels at 186,000 miles a second, it requires time to get from one place to another. In fact, it is said that in some cases, the Hubble telescope is looking back eleven billion years to see galaxies already forming. The distant galaxies are speeding away from Earth, some travelling at the speed of light.

Hubble has viewed exploding stars such as the Eta Carinae, which clearly displayed clouds of gas and dust billowing outward from its poles at 1.5 million miles an hour. Prior to Hubble, it was visible from traditional telescopes on Earth, but its details were not as certainable. But now, the evidence of the explosion is obvious. The star still burns five million times brighter than the Sun and illuminates clouds from the inside.

Hubble has also provided a close look at black holes, which are described as comic drains. Gas and dust swirl around the drain and are slowly sucked in by the incredible gravity. It has also looked into an area that looked empty to the naked eye and, within a region the size of a grain of sand, located layer upon layer of galaxies, with each galaxy consisting of billions of stars.

The Hubble telescope was named after Edwin Hubble, a 1920s astronomer who developed a formula that expresses the proportional relationship of distances between clusters of galaxies and the speeds at which they travel. Astronomers use stars known as Cepheid variables to measure distances in space. These stars dim and brighten from time to time, and they are photographed over time and charted. All the discoveries made by Hubble have allowed astronomers to learn more about the formation of early galaxies

The author implies that the satellite that carries the Hubble was specifically designed so that _________

A. the known defective mirror could be replaced in space rather than on Earth

B. maintenance could be done by travelling astronauts

Đáp án chính xác

C. the Hubble could move easily

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct word for each of the blanks from 31 to 35

One of the most important (31) _______ of a standardized test is time. You'll only be allowed a certain number of minutes for each section, so it is very important that you use your time (32) _______. The most important time strategy is pacing yourself. Before you begin, take just a few seconds to survey the test, noting the number of questions and the sections that looks easier than the rest. Then, make a rough time schedule based on the amount of time (33) _______ to you. Mark the halfway point on your test and make a note beside that mark of the time when the testing period is half over. Once you begin the test, keep moving. If you work slowly in an attempt to make fewer mistakes, your mind will become bored and begin to wander. You'll end up making far more mistakes if you're not concentrating. If you take too long to answer questions that stump you, you may end up (34) _______ out of time before you finish. So don't stop for difficult questions. Skip them and move on. You can come back to them later if you have time. A question that takes you five seconds to answer counts as much as one that takes you several minutes, so pick up the easy points first. (35) _______, answering the easier questions first helps build your confidence and gets you in the testing groove. If you're a little ahead, you know you're on track and may even have a little time left to check your work. If you're a little behind, you have several choices. You can pick up the pace a little, but do this only if you can do it comfortably
