Đáp án : B

Clean air (không khí trong lành) là một danh từ không xác định (bất kì), và không đếm được -> không dùng mạo từ a/an/the. Không khí trong thị trấn là bầu không khí đã được xác định, mà cả người nói, người nghe đều biết -> dùng mạo từ “the”

Đáp án B.

Would rather somebody did (not) do something: Muốn ai đó (không) làm gì thì hơn.

Tạm dịch: - “Bạn có phiền không nếu như tôi mở cửa?”

- “Tôi muốn bạn không làm thế, nếu như bạn không thấy phiền.”

Các lựa chọn còn lại không phù hợp:

A. Bạn giúp tôi với.

B. Bạn làm ơn mở cửa sổ giúp tôi với.

D. Bạn có phiền khi giúp tôi một việc được không?

Đáp án B

Giải thích: Câu gốc sử dụng cấu trúc câu điều kiện loại 2 để đưa ra lời khuyên:

“If + S + V(quá khứ đơn), S + would + V(nguyên thể)”  

Dịch nghĩa: Nếu tôi là bạn, tôi sẽ thích đi bằng tàu hỏa hơn là bằng xe buýt.

Phương án B. She advised me to go by train rather than by bus = Cô ấy đã khuyên tôi đi bằng tàu hỏa hơn là bằng xe buýt, là phương án có nghĩa của câu sát với nghĩa câu gốc nhất.

          A. She said that if she had been me, she would have gone by train than by bus = Cô ấy nói rằng nếu cô ấy đã là tôi, cô ấy sẽ đi bằng tàu hỏa hơn bằng xe buýt.        

Câu điều kiện loại 3 không được sử dụng để đưa ra lời khuyên. Còn câu điều kiện loại 2 khi chuyển sang câu tường thuật thì không lùi thì.

          C. She meant going by train was more interesting than going by bus = Ý cô ấy là đi bằng xe lửa thú vị hơn đi bằng xe buýt.

          D. Wherever she went, she always travelled by train = Bất cứ nơi nào cô đi, cô ấy luôn luôn đi bằng tàu hỏa.

Đáp án C

Cậu đã thật bất cẩn khi đã để các cửa sổ mở vào đêm hôm qua. 

= Cậu lẽ ra đã không nên để các cửa sổ mở vào đêm hôm qua. 

Cấu trúc: It tobe adj of sbd to V: Ai đó như thế nào khi đã làm gì. 

S should have PII: ai đó đáng lẽ ra nên làm gì trong quá khứ, nhưng thực tế đã không làm. 

Các đáp án còn lại không hợp nghĩa: 

A. Cậu không nên để các cửa sổ mở vào tối qua

B. Cậu bất cẩn đến nỗi cậu đã để các cửa sổ mở vào tối qua. 

Cấu trúc: S tobe so adj that S V O: ai đó quá như thế nào đễn nỗi mà. 

D. Cậu có lẽ đã không cẩn thận vì cậu đã để các cửa sổ mở vào tối qua. 

S migh have PII: có lẽ đã- chỉ một tiên đoán trong quá khứ nhưng không có cơ sở.

Đáp án B

Kiến thức: Mạo từ

Giải thích:

town (thị trấn) là danh từ số ít và xuất hiện lần đầu trong câu nên chưa xác định => dùng mạo từ “a”

“country” được hiểu là vùng nông thôn nên xác định => dùng cụm từ “in the country”

 

Tạm dịch: Bạn thích sống ở thị trấn hay nông thôn?

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 from 36 to 42.

Forces other than damaging winds are also at work inside tornadoes. Sometimes, as the writhing, twisting funnel passes over a house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion is caused by the low air pressure at the center of a tornado.

The pressure at the center of a tornado is usually 13 pounds per square inch. However, inside the house, the air pressure is normal, about 15 pounds per square inch. The difference of 2 pounds per square inch between the inside and outside pressure may not seem like much. But suppose a tornado funnel passes over a small building that measures 20 by 10 by 10 feet. On each square inch of the building, there is 2 pounds of pressure from the inside that is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57, 600 pounds. The pressure on the four walls adds up to 172,800 pounds.

If windows are open in the building, some of the inside air will rush out through them. This will balance the pressure inside and outside the building. But if the windows are shut tightly, the enormous inside pressure may cause the building to burst.

Unfortunately, heavy rain and hail often occur in thunderstorms that later produce tornadoes. So people frequently shut all windows to protect their property. This may cause far worse damage later. For the same reason, tornado cellars must have an air vent. Otherwise, the cellar door might be blown out when a tornado passes over it.

According to the passage, people close their windows to prevent damage caused by ________

A. tornadoes

B. thunderstorms

C. uprooted trees

D. bursting structures

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 from 43 to 50.

        An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous changes. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled - a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions.

        Many of more important air pollutants, such as sulfur oxides, carbon monoxides and nitrogen oxides are found in nature. As the Earth developed, the concentration of these pollutants was altered by various chemical reactions; they became components in biogeochemical cycles. These serve as an air purification scheme by allowing the compounds to move from the air to the water or soil. On a global basis, nature's output of these compounds dwarfs that resulting from human activities.

        However, human production usually occurs in a localized area, such as a city. In such a region, human output may be dominant and may temporarily overload the natural purification scheme of the cycles. The result is an concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a substance to be a pollutant; in fact, the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0. 08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however has a natural level of 0. 1 ppm and is not usually a pollutant until its level reaches about 15 ppm.
