The mosquito is an insect that speards some of the worst diseases of man and animals. Certain kinds of mosquitoes carry the germs that cause such serious diseases as malaria, and yellow fever. When a mosquito“bites”, it may leave germs behind. Many kinds of mosquitoes do not spreaddiseases, but they have painful “bites”.Mosquitoes are found in all parts of the world, even near the NorthPole. Most kinds of mosquitoes that carry diseases live in the hot, damplands near the Equator. In some countries, mosquitoes often gather in
great swarms that look like clouds. They attack men, interfering with suchwork as fishing, lumbering, and mining.Man controls mosquitoes in many ways. Scientists have developed chemicals called insecticides, which kill mosquitoes and other insects.Small amounts of these chemicals kill mosquitoes when sprayed in home,garages where they grow. Mosquitoes lay their eggs in marshes, swampsand other pools of quiet water. Engineers may build canals throughmarshes to drain off the water, and often fill small pools and swamps with soil.

(4) __Although_____ deet works well, it has some serious drawbacks: it can damage clothes and some people are allergic to it.

True/false
Air pollution is a cause of ill-health in human beings. In a lot of countries there are laws limiting the amount of smoke which factories can produce. Although there isn`t enough information on the effects of smoke in the atmosphere, doctors have proved that air pollution causes lung diseases.
The gases from the exhausts of cars have also increased air pollution in most cities. The lead in petrol produces a poisonous gas which often collects in busy streets surrounded by high buildings. Children who live in areas where there is a lot of lead in the atmosphere cannot think as quickly as other children and are clumsy when they use their hands.
There are other long-term effects of pollution. If the gases in the atmosphere continue to increase, the earth`s climate may become warmer. A lot of the air near the Poles may melt and may cause serious floods.

Chúng ta sống trong một thế giới năng động, và môi trường sống luôn luôn trải qua những thay đổi ở tất cả các cấp độ. Tuy nhiên, những thay đổi tự nhiên thường xảy ra ở tốc độ chậm để tác động đến từng loài có xu hướng nhỏ - ít nhất là trong ngắn hạn
Khi tốc độ thay đổi được tăng tốc đáng kể, có thể không có thời gian để các loài cá thể phản ứng với hoàn cảnh mới, và các hiệu ứng có thể là thảm họa. Tóm lại, đây là lý do khiến mất môi trường sống nhanh chóng được coi là nguyên nhân chính gây nguy hiểm cho loài, và không có lực lượng nào mạnh hơn trong vấn đề này so với con người. Ở một mức độ nào đó, mọi phần của trái đất đã bị ảnh hưởng bởi các hoạt động của con người, đặc biệt là trong thế kỷ qua. Điều này áp dụng trên hầu hết mọi quy mô, từ việc mất vi khuẩn trong đất đã từng hỗ trợ rừng nhiệt đới, đến sự tuyệt chủng của cá và các loài thủy sinh khác trong môi trường nước ngọt bị ô nhiễm, thay đổi khí hậu toàn cầu gây ra bởi việc thải khí nhà kính. Từ quan điểm của một đời người, những thay đổi như vậy có thể khó phát hiện và ảnh hưởng của chúng đối với từng loài có thể khó dự đoán. Nhưng bài học là đủ rõ ràng. Ví dụ, mặc dù nhiều quốc gia đã có kế hoạch trồng nhiều khu rừng nhiệt đới, chúng rất dễ bị phá hủy bởi vì các loại đất mà chúng phát triển rất nghèo trong các chất dinh dưỡng sẵn có. Nhiều thế kỷ có thể được yêu cầu mang lại một khu rừng bị cắt giảm hoặc bị đốt cháy trong không gian vài năm. Nhiều loài động vật và thực vật bị đe dọa nghiêm trọng trên thế giới sống trong các khu rừng như vậy, và chắc chắn rằng một số lượng lớn chúng sẽ biến mất nếu tỷ lệ mất rừng hiện tại tiếp tục. Môi trường sống trên thế giới là không thể thay đổi và tồn tại cố định.
