Traditionally in America, helping the poor was a matter for private charities or local governments. Arriving immigrants depended mainly on predecessors from their homeland to help them start a new life. In the late 19th and early 20th centuries, several European nations instituted public-welfare programs. But such a movement was slow to take hold in the United States because the rapid pace of industrialization and the ready availability of farmland seemed to confirm the belief that anyone who was willing to work could find a job. Most of the programs started during the Depression era were temporary relief measures, but one of the programs Social Security - has become an American institution. Paid for by deductions from the paychecks of working people, Social Security ensures that retired persons receive a modest monthly income and also provides unemployment insurance, disability insurance, and other assistance to those who need it. Social Security payments to retired persons can start at age 62, but many wait until age 65, when the payments are slightly higher. Recently, there has been concern that the Social Security fund may not have enough money to fulfill its obligations in the 21st century, when the population of elderly Americans is expected to increase dramatically. Policy makers have proposed various ways to make up the anticipated deficit, but a long-term solution is still being debated. In the years since Roosevelt, other American presidents have established assistance programs. These include Medicaid and Medicare; food stamps, certificates that people can use to purchase food; and public housing which is built at federal expense and made available to persons on low incomes. Needy Americans can also turn to sources other than the government for help. A broad spectrum of private charities and voluntary organizations is available. Volunteerism is on the rise in the United States, especially among retired persons. It is estimated that almost 50 percent of Americans over age 18 do volunteer work, and nearly 75 percent of U.S. households contribute money to charity. Question 36: It took welfare program a long time to gain a foodhold in the US due to the rapid growth of _________. A. industrialization B. population C. urbanization D. modernization Question 37: The Social Security program has become possible thanks to _________. A. enforcement laws B. deductions from wages C. donations from companies D. people's willingness to work Question 38: Most of the public assistance programs ________ after the severe economic crisis. A. were introduced into institutions B. did not become institutionalized C. functioned truthfully in institutions D. did not work in institutions Question 39: American on low incomes can seek help from _________. A. non-governmental agencies B. governmental agencies C. federal government D. state government Question 40: The word "instituted" in the first paragraph mostly means _________. A. executed B. introduced C. studied D. enforced Question 41: That Social Security payments will be a burden comes from the concern that ____________. A. the program discourages working people B. younger people don't want to work C. elderly people ask for more money D. the number of elderly people is growing Question 42: New immigrants to America could seek help for _________. A. only charity organizations B. volunteer organizations C. the people who came earlier D. the US government organization

  s a me n g l i s h . e d u . v n - L u y ệ n t h i Đ ạ i h ọ c T i ế n g A n h P a g e 4 | 8 Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks. According to the best evidence gathered by space probes and astronomers, Mars is an inhospitable planet, more similar to Earth’s Moon than to Earth itself - a dry, stark, seemingly lifeless world. Mars’ air pressure is equal to Earth’s at an altitude of 100,000 feet. The air there is 95 percent carbon dioxide. Mars has no ozone layer to screen out the sun’s lethal radiation. Daytime temperatures may reach above freezing, but because the planet is blanketed by the mere wisp of an atmosphere, the heat radiates back into space. Even at the equator, the temperature drops to -50C (-60F) at night. Today there is no liquid water, although valleys and channels on the surface show evidence of having been carved by running water. The polar ice caps are made of frozen water and carbon dioxide, and water may be frozen in the ground as permafrost. Despite these difficult conditions, certain scientists believe that there is a possibility of transforming Mars into a more Earth-like planet. Nuclear reactors might be used to melt frozen gases and eventually build up the atmosphere. This in turn could create a “greenhouse effect” that would stop heat from radiating back into space. Liquid water could be thawed to from a polar ocean. Once enough ice has melted, suitable plants could be introduced to build up the level of oxygen in the atmosphere so that, in time, the planet would support animal life from Earth and even permanent human colonies. “This was once thought to be so far in the future as to be irrelevant,” said Christopher McKay, a research scientist at NASA. “But now it’s starting to look practical. We could begin work in four or five decades.” The idea of “terraforming” Mars, as enthusiasts call it, has its roots in science fiction. But as researchers develop a more profound understanding of how Earth's ecology supports life, they have begun to see how it may be possible to create similar conditions on Mars. Don’t plan on homesteading on Mars any time soon, though. The process could take hundreds or even thousands of years to complete and the cost would be staggering. Question 43: The word "there" in bold in paragraph 1 refers to _______. A. the Earth's Moon B. Mars C. outer space D. a point 100 miles above the Earth Question 44: Which of the following does the author NOT list as a characteristic of the planet Mars that would make colonization difficult? A. There is little liquid water. B. The sun's rays are deadly. C. Daytime temperatures are dangerously high. D. Night time temperatures are extremely low. Question 45: It can be inferred from the passage that the "greenhouse effect" mention in paragraph 3 is ________. A. the direct result of nuclear reactions B. the cause of low temperatures on Mars C. caused by the introduction of green plants D. a possible means of warming Mars Question 46: According to Christopher McKay, the possibility of transforming Mars __________. A. could only occur in science fiction stories B. will not begin for hundreds, even thousands of years C. is completely impractical D. could be started in forty to fifty years Question 47: According to the article, the basic knowledge needed to transform Mars comes from _________. A. the science of astronomy B. data from space probes C. a knowledge of Earth's ecology D. science fiction stories Question 48: According to the passage, the Martian atmosphere today consists mainly of _______. A. oxygen B. carbon dioxide C. ozone D. water vapor Question 49: The word "inhospitable" in bold in paragraph 1 is closest in meaning to _____. A. generous B. uninhabitable C. hostile D. green Question 50: What is the main idea of the passage? A. The possibility of changing the Martian environment B. The challenge of interplanetary travel C. The need to study the Martian ecology D. The advantages of establishing colonies on Mars

Dẫn chứng bắt đầu từ câu thứ 2 đoạn 2: "Paid for by deductions from the paychecks of working people, Social Security ensures that retired persons receive a modest monthly income and also provides unemployment insurance, disability insurance, and other assistance to those who need it".

Dẫn chứng ở đoạn 2: "Daytime temperatures may reach above freezing, but because the planet is blanketed by the mere wisp of an atmosphere, the heat radiates back into space. Even at the equator, the temperature drops to -50C (-60F) at night". Như vậy nhiệt độ ban ngày không phải là cao đến mức nguy hiểm mà chỉ có thể đạt được trên mức đông lạnh thôi. Ngoài ra, có thể dễ dàng thấy các đáp án còn lại đã được nhắc đến. Question 45: Đáp án D. Câu hỏi này cần phải suy luận một chút: "This in turn could create a “greenhouse effect” that would stop heat from radiating back into space". Đọc lại chỗ này ở đoạn 2: "Daytime temperatures may reach above freezing, but because the planet is blanketed by the mere wisp of an atmosphere, the heat radiates back into space".  Có thể thấy 1 nguyên nhân khiến cho nhiệt độ thấp là do "the heat radiates back into space". Trong khi đó "greenhouse effect" thì lại "stop the heat from radiating back into space", tức là nó sẽ có thể khiến nhiệt độ ấm lên. Question 46: Đáp án D. Dẫn chứng ở cuối đoạn 3: "We could begin work in four or five decades". Question 47: Đáp án C. Dẫn chứng ở đoạn cuối: "But as researchers develop a more profound understanding of how Earth's ecology supports life, they have begun to see how it may be possible to create similar conditions on Mars". Question 48: Đáp án B. Dẫn chứng ở câu cuối đoạn 1: "The air there is 95 percent carbon dioxide". Question 49: Đáp án B. Trong ngữ cảnh này thì: inhospitable (adj): không ở được, không trú ngụ được (do khí hậu, môi trường...) ~ uninhabitable (adj): không ở được, không cư trú được. Question 50: Đáp án A. Sau khi đọc hiểu thì có thể thấy ý chính của bài đọc này là "Khả năng thay đổi môi trường trên sao Hỏa".
