The "greenhouse effect" is the warming that happens when certain gases in Earth's atmosphere (25) ________ heat. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse. First, sunlight shines onto the Earth's surface, (26) ______ it is absorbed and then radiates back into the atmosphere as heat. In the atmosphere, “greenhouse gases trap some of this heat, and the the rest escapes into space. The more greenhouse gases are in the atmosphere, the more heat gets trapped.

        Scientists have known about the greenhouse effect since 1824, when Joseph Fourier calculated that the Earth would be much colder if it had no atmosphere. This greenhouse effect is what keeps the Earth's climate (27) _________. Without it, the Earth's surface would be an average of about 60 degrees Fahrenheit cooler. Scientists often use the term "climate change" instead of global warming. This is because as the Earth's average temperature climbs, winds and ocean currents move heat around the globe in ways that can cool some areas, warm (28) ___________ones, and change the amount of rain and snow falling. (29)_________, the climate changes differently in different areas.

Question 25:  A. seize (túm lấy)        B. capture(bắt giữ)      C. trap (giữ lại)           D. grasp (ôm chặt)

Question 26:   A. which                     B. where                      C. that                         D. which

Question 27:  A. lively                       B. alive                        C. livable                    D. living

Question 28:   A. other                       B. another                   C. one                         D. the other

Circling the Sun at an average distance of 149 million kilometers (93 million miles), Earth is the third planet from the Sun and the fifth largest planet in the solar system.

 

   Our planet’s rapid spin and molten nickel-iron core give rise to an extensive magnetic field which, coupled the atmosphere, shields us from nearly all of the harmful radiation coming from the Sun and other stars. Earth’s atmosphere protects us from meteors as well, most of which burn up in the Earth’s atmosphere before they can strike the surface. The planet active geological processes have left no evidence of the ancient pelting it almost certainly received soon after it formed about 4.6 billion years ago. The Earth has a single natural satellite – the moon.

QuestionThe word distinguishing as it is used in this selection means ________.

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.
