Câu hỏi: 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 following questions from 22 to 28.
Have you ever entered a tropical rainforest? It's a special, dark place completely different from anywhere else. A rainforest is a place where the trees grow very tall. Millions of kinds of animals, insects, and plants live in the rainforest. It is hot and humid in a rainforest. It rains a lot in the rainforest, but sometimes you don't know it's raining. The trees grow so closely together that rain doesn't always reach the ground.
Rainforests make up only a small part of the Earth's surface, about six percent. They are found in tropical parts of the world. The largest rainforest in the world is the Amazon in South America. The Amazon covers 1.2 billion acres, or almost five million square kilometers. The second largest rainforest is in Western Africa. There are also rainforests in Central America, Southeast Asia, Northeastern Australia, and the Pacific Islands. Rainforests provide us with many things. In fact, the Amazon Rainforest is called the "lungs of our planet" because it produces twenty percent of the world's oxygen. One fifth of the world's fresh water is also found in the Amazon Rainforest. Furthermore, one half of the world's species of animals, plants, and insects live in the Earth's rainforests. Eighty percent of the food we cat first grew in the rainforest. For example, pineapples, bananas, tomatoes, corn, potatoes, chocolate, coffee, and sugar all came from rainforests. Twenty-five percent of the drugs we take when we are sick are made of plants that grow only in rainforests. Some of these drugs are even used to fight and cure cancer. With all the good things we get from rainforests, it's surprising to find that we are destroying our rainforests. In fact, 1.5 acres, or 6,000 square meters, of rainforest disappear every second. The forests are being cut down to make fields for cows, to harvest the plants, and to clear land for farms. Along with losing countless valuable species, the destruction of rainforests creates many problems worldwide. Destruction of rainforests results in more pollution, less rain, and less oxygen for the world.
A. Because the branches are too dense for the rain to touch the ground.
B. Because they are the habitats of millions of flora and fauna.
C. Because it hardly rains in the rainforests.
D. Because the trees grow very tall there.

D. Because the trees grow very tall there.
Giải thích:
Tại sao mọi người không biết trời mưa trong rừng nhiệt đới?
A. Vì cành cây quá rậm rạp để mưa chạm được đất.
B. Vì chúng là nơi sinh sống của hàng triệu loài động thực vật.
C. Vì trời hầu như không mưa trong các khu rừng nhiệt đới.
D. Vì ở đó cây cối mọc rất cao.
Thông tin:
It rains a lot in the rainforest, but sometimes you don't know it's raining. The trees grow so closely together that rain doesn't always reach the ground. (Trong rừng nhiệt đới mưa rất nhiều, nhưng đôi khi bạn không biết trời đang mưa. Cây cối mọc san sát nhau đến nỗi không phải lúc nào mưa cũng có thể chạm tới mặt đất.)
