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.

It’s a sound you will probably never hear, a sickened tree sending out a distress signal. But a group of scientists has heard the cries, and they think some insects also hear the trees and are drawn to them like vulture to a dying animal. Researchers with the US Department of Agriculture’s Forest Service fastened sensors to the bark of drought-stricken trees clearly heard distress calls. According to one of the scientists, most parched trees transmit their plight in the 50-hertz to 50-kilohertz range. (The unaided human ear can detect no more than 20 kilohertz). Red oak, maple, white pine, and birch all make slightly different sounds in the form of vibrations at the surface of the wood.

The scientists think that the vibrations are created when the water columns inside tubes that run along the length of the tree break, a result of too little water following through them. These fractured columns send out distinctive vibration pattems. Because some insects communicate at ultrasonic frequencies, they may pick up the trees' vibration and attack the weakened trees. Researchers are now running tests with potted trees that have been deprived of water to see if the sound is what attracts the insects. “Water-stressed trees also smell differently from other trees, and they experience thermal changes, so insects could be responding to something other than sound”, one scientist said

All the following are mentioned as possible factors in drawing insects to weakened trees EXCEPT ________ 

A. sounds 

B. changes in colours 

C. smells 

D. thermal changes

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.

Trees are useful to man in three very important ways: they provide him with wood and other products, they give him shade, and they help to prevent drought and floods.

Unfortunately, in many parts of the world man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had.

Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.

Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by making charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear.

This does not only mean that there will be fewer trees. The results are even more serious. For where there are trees their roots break the soil up, allowing the rain to sink in and also bind the soil, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert.

Trees are useful to man mainly in three ways, the most important of which is that they can _______.

A. keep him from the hot sunshine

B. make him draw quick profit from them

C. enable him to build warships

D. protect him from drought and floods

D. bảo vệ con người khỏi hạn hán và lũ lụt

Tạm dịch: Cây xanh rất hữu ích cho con người theo ba cách rất quan trọng: chúng cung cấp cho một người gỗ và các sản phẩm khác, chúng cho người đó bóng mát, và giúp ngăn chặn hạn hán và lũ lụt.

Thật không may, ở nhiều nơi trên thế giới, con người đã không nhận ra rằng lợi ích thứ ba trong số đó là quan trọng nhất.

Cây xanh rất hữu ích cho con người theo ba cách rất quan trọng: chúng cung cấp cho một người gỗ và các sản phẩm khác, chúng cho người đó bóng mát, và giúp ngăn chặn hạn hán và lũ lụt.

Thật không may, ở nhiều nơi trên thế giới, con người đã không nhận ra rằng lợi ích thứ ba trong số đó là quan trọng nhất. Trong sự háo hức của mình để thu được lợi nhuận nhanh chóng từ cây xanh, người ta đã chặt phá chúng với số lượng lớn, chỉ để thấy rằng không có chúng, người ta đã mất đi những người bạn thân nhất mà mình có.

Hai ngàn năm trước, một quốc gia giàu có và hùng mạnh đã chặt hạ cây cối của mình để chế tạo tàu chiến, để tự mình trở thành một đế chế. Nó đã giành được đế chế, nhưng không có cây cối, đất đai của nó trở nên khô cứng và bạc màu. Khi đế chế sụp đổ, đất nước này phải đối mặt với lũ lụt và nạn đói.

Mặc dù chính phủ nhận ra tầm quan trọng của nguồn cung cấp cây xanh dồi dào, thật khó để thuyết phục người dân nhìn thấy điều này. Dân làng cần gỗ để nấu thức ăn của mình và người đó có thể kiếm tiền bằng cách đốt than hoặc bán gỗ cho người dân thị trấn. Anh ấy thường quá lười biếng hoặc quá bất cẩn để

trồng và chăm sóc cây. Vì vậy, trừ khi chính phủ có một hệ thống kiểm soát tốt, hoặc có thể giáo dục người dân, các khu rừng sẽ dần biến mất.

Điều này không chỉ có nghĩa là sẽ có ít cây cối hơn. Kết quả thậm chí còn nghiêm trọng hơn. Đối với những nơi có cây cối, rễ của chúng xới đất, cho phép nước mưa chìm xuống và liên kết đất, do đó ngăn chặn việc nó bị cuốn trôi một cách dễ dàng, nhưng nơi không có cây, đất trở nên khô cứng và bạc màu. Mưa rơi trên mặt đất cứng và chảy trên bề mặt, gây ra lũ lụt và mang theo lớp đất mặt màu mỡ, nơi mà cây trồng phát triển rất tốt. Khi tất cả lớp đất mặt đã biến mất, không còn gì ngoài một sa mạc vô giá trị.
