II. Fill in the blank of the following passage with ONE suitable word. Write your answer on your answer sheet.

There is much more water than land (1)___________ the surface of the earth. The sea and oceans (2)_____________ nearly four-fifths of the whole world, and only one-fifth of (3)__________ land. If you traveled over the earth (4)______ ________different directions, you would have to spend much more of your time (5)________________ on water than on roads or railways. We sometimes forget that (6)_______________ every mile of land there is four miles of water.

We use the word seas to (8)______________ those parts of water surface which (9)______________ only a few hundreds of miles wide, the word oceans to describe the huge areas of water which are thousands of miles wide (10)__________ very deep.

III. Read the following passage carefully and choose the best answer to each question. Identify your answer by writing the corresponding letter A, B, C or D on your answer sheet.

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is basic human right. But acid rain, industrial pollution and garbage have made many sources of water undrinkable. Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. But they are being destroyed by the massive volumes of industrial effluent which pours into the lake everyday. Even where law existed, the government did not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world’s water surface. But it is the dumping ground for 50% of all marine pollution. Almost 16 countries regularly throw industrial wastes a few miles off shore.

Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect this precious source. We should do something now.

1. According to the writer, one environmental problem in the world today is ________ .

A. acid rain B. industrial pollution. C. safe water shortage. D. population explosion .

2. Many sources of water are not drinkable because of _______ .

A. acid rain. B. industrial pollution. C. garbage D. all A, B, C, are correct

3. What is serious problem of Lake Baikal in Russia?

A. It contains a rich variety of animals and plants.

B. It is polluted by massive volumes of industrial wastes discharged into it .

C. It has 1,300 rare species that do not exist anywhere else in the world .

D. The government did not have the power to enforce laws and regulations.

4. How many countries throw industrial waste into the Mediterranean Sea regularly?

A. nearly 16 B. exactly 16. C. exactly 15 D. less than 15.

5. What is the message to the reader?

A. We should take action to protect our water resources.

Read the following passage, and mark the letter (A, B, C or D) on your answer sheet to indicate the correct answer to each question.

Coincident with concerns about the accelerating loss of species and habitats has been a growing appreciation of the importance of biological diversity, the number of species in a particular ecosystem, to the health of the Earth and human well-being. Much has been written about the diversity of terrestrial organisms, particularly the exceptionally rich life associated with tropical rain-forest habitats. Relatively little has been said, however, about diversity of life in the sea even though coral reef systems are comparable to rain forests in terms of richness of life.

An alien exploring Earth would probably give priority to the planet's dominant, most-distinctive feature ― the ocean. Humans have a bias toward land that sometimes gets in the way of truly examining global issues. Seen from far away, it is easy to realize that landmasses occupy only one-third of the Earth's surface. Given that two- thirds of the Earth's surface is water and that marine life lives at all levels of the ocean, the total three-dimensional living space of the ocean is perhaps 100 times greater than that of land and contains more than 90 percent of all life on Earth even though the ocean has fewer distinct species.

The fact that half of the known species are thought to inhabit the world's rain forests does not seem uprising, considering the huge numbers of insects that comprise the bulk of the species. One scientist found many different species of ants in just one tree from a rain forest. While every species is different from every other species, their genetic makeup constrains them to be insects and to share similar characteristics with 750,000 species of insects. If basic, broad categories such as phyla and classes are given more emphasis than differentiating between species, then the greatest diversity of life is unquestionably the sea. Nearly every major type of plant and animal has some representation there.

To appreciate fully the diversity and abundance of life in the sea, it helps to think small. Every spoonful of ocean water contains life, on the order of 100 to 100,000 bacterial cells plus assorted microscopic plants and animals, including larvae of organisms ranging from sponges and corals to starfish and clams and much more.

Which of the following conclusions is supported by the passage?

A. Ocean life is highly adaptive

B. More attention needs to be paid to preserving ocean species and habitats

C. Ocean life is primarily composed of plants

D. The sea is highly resistant to the damage done by pollutants

B. Đời sống đại dương chủ yếu bao gồm thực vật.

C. Cần chú ý nhiều hơn để bảo tồn các loài sinh vật biển và môi trường sống.

D. Biển có khả năng chống chịu thiệt hại cao do các chất ô nhiễm gây ra.

Đoạn văn đề cập sự đa dạng cách loài ở biển, được so sánh với các loài ở rừng => nhằm mục đích khuyến khích mọi người nên bao tồn các loài ở đại dương và môi trường sống của chúng.  

Dịch bài đọc:

Trùng hợp với những lo ngại về sự mất mát nhanh chóng của các loài và môi trường sống là sự đánh giá ngày càng tăng về tầm quan trọng của đa dạng sinh học, số lượng loài trong một hệ sinh thái cụ thể, với sức khỏe của trái đất và con người. Phần lớn đã được viết về sự đa dạng của các sinh vật trên cạn, đặc biệt là các sinh cảnh rừng mưa nhiệt đới đặc biệt phong phú. Tuy nhiên, tương đối ít nói về sự đa dạng của sự sống trên biển mặc dù các hệ thống rạn san hô có thể so sánh với rừng mưa về sự phong phú của sự sống.

Một người ngoài hành tinh khám phá Trái đất có lẽ sẽ ưu tiên cho những kẻ thống trị của hành tinh - đặc điểm đặc biệt nhất - đại dương. Con người có thiên hướng về đất mà đôi khi ngăn cản việc kiểm tra các vấn đề toàn cầu. Nhìn từ xa, rất dễ dàng để nhận ra các vùng đất chỉ chiếm một phần ba bề mặt Trái Đất. Cho rằng hai phần ba bề mặt Trái đất là nước và sinh vật biển sống ở tất cả các cấp của đại dương, tổng không gian sống ba chiều của đại dương có lẽ lớn hơn 100 lần so với đất và chứa hơn 90 phần trăm sự sống trên trái đất mặc dù đại dương có ít loài khác biệt.

Thực tế là một nửa số loài đã biết được cho là sống trong các khu rừng mưa của thế giới dường như không đáng ngạc nhiên, khi xem xét một số lượng lớn các loài côn trùng bao gồm phần lớn các loài. Một nhà khoa học đã tìm thấy nhiều loài kiến khác nhau chỉ trong một cây từ rừng mưa. Trong khi tất cả các loài đều khác biệt với mọi loài khác, gen của chúng hạn chế chúng là côn trùng và có đặc điểm tương tự với 750.000 loài côn trùng. Nếu các loại cơ bản, rộng như phyla và các lớp được nhấn mạnh hơn sự khác biệt giữa các loài, thì sự đa dạng lớn nhất của sự sống là không thể nghi ngờ bằng đường biển. Gần như tất cả các loại thực vật và động vật chính đều hiện diện ở đó.

Để đánh giá đầy đủ sự đa dạng và phong phú của sự sống trên biển, nó giúp "nghĩ nhỏ". Mỗi thìa nước đại dương, vào khoảng 100 đến 100.000 tế bào vi khuẩn cộng với các loại thực vật và động vật vi mô, bao gồm ấu trùng của các sinh vật từ bọt biển và san hô đến sao biển và trai và nhiều hơn nữa.
