六、自然與環保類

Believe it or not, oceans and seas are easy to be harmed by the development of human society. They are also influenced by man-made pollution easily. It is human beings that do great harm to the ocean ecosystems.

The coral reefs（珊瑚礁）are fine ecosystems that provide food and protection for many ocean creatures（生物）. The coral in almost all of the oceans is in danger from pollution. Chemicals from factories end up in the seas and oceans and destroy（破壞）coral reefs. If the coral systems die，some ocean creatures will be sure to die out.

Protecting the ocean also has something to do with the protection of ocean wildlife like dolphins. The fishing industry depends on modern ways to catch many fish in order to earn more money. But the nets for fishing also catch other sea animals. The fishing boat workers are advised to check their nets and set other ocean animals free. But the boats are in a hurry to make money and often other ocean animals are caught with fish.

(　　) What does the second paragraph mainly tell readers?

A. The importance of protecting coral systems.

B. Coral reefs are home to ocean animals.

C. The great harm caused by factory pollution.

D. How ocean creatures depend on coral reefs.

本文是一篇自然與環保類的文章，主要講述了人為活動已經嚴重破壞了海洋生態系統。如：許多海洋生物依附于珊瑚礁生存，但是現在大部分珊瑚礁已經被破壞了，人們過度捕撈給海洋生物帶來了致命打擊。最后呼吁大家要保護海洋生態環境。

本題題干意為：文章第二段主要想告訴讀者什么？通讀第二段可知，主要在強調珊瑚礁的重要性，但是珊瑚礁現在處境危險，所以呼吁大家要保護珊瑚礁。故答案為A。

自然環境與我們每個人的生活都息息相關，所以，保護環境，使人與自然和諧發展是每個人不可推卸的責任。我們在做這類題目時，可以從語篇的整體理解和細節推理等方面入手，帶著問題從文中尋找相關的信息，這樣答題就會既準確又快速。
