题目

阅读理解 Australian scientists are leading an international project to build an extremely powerful ground-based telescope（望远镜）. The telescope's short name is MAVIS，it is designed to correct a problem common to Earth-based telescopes：image blurring（图像模糊） caused by the atmosphere（大气）. Scientists in Australia say the new technology will help them explore how the first stars formed 13 billion years ago. The telescope will also examine changes in the weather on planets and moons in our solar system. It will provide a deeper and clearer look into space than the Hubble Space Telescope. Images produced by MAVIS are expected to be three times clearer than the Hubble Space Telescope. Sent into space in 1990, Hubble orbits（环绕） Earth from about 550 kilometers away, well outside the planet's atmosphere. Richard McDermid of Macquarie University in Sydney says the new telescope will change the way we explore space. He said the telescope will allow scientists to push into a new frontline（前沿） of the furthest and faintest（最微小） things we can see. "The new view will include the universe's earliest galaxies（星系）. This also means an exploration of the past, " McDermid said, "because when we look far away in astronomy we are also looking far back in time because it takes time for the light to reach us. " The MAVIS team, which includes scientists from Macquarie University, Italy's National Institute for Astrophysics, and France's Laboratoired Astrophysique, is led by the Australian National University. The telescope will be placed in Chile and run by the European Southern Observatory, a research organization based in Germany. It is expected to take seven years tobuild and cost ＄44 million. （1） What is the purpose of MAVIS? A . To provide clearer pictures of outer space. B . To find the universe's earliest galaxies. C . To observe the planets in different weather. D . To examine the changes in the solar system. （2） What can we know about MAVIS? A . It will be placed on other planets outside Earth. B . It will help explore the past of the universe. C . It will replace the Hubble Space Telescope. D . It will be the first telescope to travel to space. （3） What is the purpose of McDermid's words? A . To give an example. B . To explain a concept. C . To describe a fact. D . To make a prediction. （4） What is the text mainly about? A . The importance of outer space research. B . The introduction to a new space program. C . Australia's plan to build a super telescope. D . The difficulties of exploring the universe. 答案： A B D C
