Life in the Universe

    Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such a life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extraterrestrial life forms might be like.

What sorts of planets are most likely to develop life? Most scientists likely to agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble the continuous movement ands transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important.

The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and burn out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problems. First of all, planets is their habitable zones will be so close to the stars that they will be “tidally blocked”- that is one side of the planet will always face the star in perpetual daylight with the other side in perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem. 
Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two. 
Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas gains, such as Saturn and Jupiter, in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth

All of the following are mentioned in the passage as necessary for the development of life except ______.

A. rock

B. carbon

C. oxygen

D. water

Tất cả những điều sau đây được đề cập tới trong đoạn văn như là những điều cần thiết cho sự phát triển của sự sống, ngoại trừ ______.

A. đá.

B. khí các-bon.

C. khí ô-xi.

D. nước.

Dẫn chứng ở đoạn 2: “Most scientists likely to agree that a habitable planet must be terrestrial, or rock-based (A), with liquid surface water (D) and biogeochemical cycles that somewhat resemble the continuous movement ands transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and and the Earth’climate depend. Since (as far as we know) all life is carbon-based (B), a stable carbon cycle is especially important” – (Hầu hết các nhà khoa học đồng ý rằng một hành tinh có sự sống phải có mặt đất, hoặc nền đá, cùng với bề mặt chất lỏng chảy trên đó và các chu trình địa hóa học sinh vật tương tự như sự vận động liên tục và sự trao đổi vật chất với môi trường. Chu trình đó bao gồm sự lưu thông của các nguyên tố và chất dinh dưỡng mà sự sống và khí hậu trên hành tinh đó phục thuộc vào. Bởi vì (như ta đã biết) thì mọi sự sống đều dựa trên các-bon, và một chu trình các-bon ổn định là đặc biệt quan trọng).

Đáp án B

Để sự sống có thể phát triển, thì quỹ đạo của một hành tinh không được______.

A. có tính ổn định.

B. quá gần quỹ đạo của một hành tinh khác.

C. trên cùng một hành tinh như quỹ đạo của một hành tinh khác.

D. hẹp hơn phạm vi có sự sống của một ngôi sao.

Most solar systems have more than one planet, which influence each other’s orbits with their own gravity” – (Đương nhiên là không phải tất cả ngôi sao có kích cỡ phù hợp sẽ phát triển được sự sống, chúng cũng phải có những hành tinh có bề mặt cùng với quỹ đạo phù hợp. Hầu hết những hệ mặt trời đều có nhiều hơn 1 hành tinh, điều đó làm quỹ đạo của chúng tác động lẫn nhau bằng chính lực hấp dẫn của chúng).

=> Để có sự sống thì quỹ đạo của một hành tinh không được quá gần với quỹ đạo của 1 hành tinh khác, không thì chúng sẽ tác động lẫn nhau bằng chính lực hấp dẫn của mình, khiến cho sự sống không thể phát triền

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50

    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.

Public assistance has become more and more popular due to the ______.

A. young people’s voluntarism only

B. volunteer organizations

C. people’s growing commitment to charity

D. innovations in the tax system
