1. A shark can no longer swim and slowly dies. 鲨鱼不能再游泳然后慢慢死掉。 no longer意思是“不再”
e.g. I’m no longer a student. 我不再是个学生了。
有两个短语和no longer同义，即not…any longer和not…any more，但他们侧重的方面不同。 no longer和not…any longer侧重时间。
e.g. He no longer lives here.= He doesn’t live here any longer.
他不在这儿居住了。(一个时间以前他住在这儿，过了这个时间，他就离开
了。)
not…any more侧重侧重程度和数量
e.g. You can drink no more. = You can’t drink any more.
你不能再喝了。(喝酒的量到了一定程度，不能再继续下去了。) 2. This method is not only cruel, but also harmful to the environment. 这种方法不但残忍而且对环境有害。 not only…but also…
用于连接两个表示并列关系的成分，着重强调后者，其意为“不仅……而且……”; 其中的also有时可以省略。
e.g. 1) She not only plays well, but also writes music. 她不仅很会演奏，而且还会作曲。 2) Not only men but also women were chosen. 不仅仅是男的，女的也有被选中的。
若连接两个成分作主语，其谓语通常与靠近的主语保持一致。 e.g. Not only you but also he has to leave. 不只是你，他也得离开。 not only放在句首，后接句子时要用倒装结构。
e.g. Not only had the poor man been fined, but also he had been sent to prison. 这个可怜的人不仅被罚款，而且还被送进了监狱。 be harmful to 对… 有害
e.g. Smoking is harmful to the health. 吸烟有损健康。 Playing computer games much is harmful to students.
电脑游戏玩太多对学生有害。
3. Sharks are at the top of the food chain in the ocean’s ecosystem. 鲨鱼位于海洋生物系统食物链的顶部。

He shouted at the top of his voice in order that he might be heard. 他尽力大声叫喊, 以便别人能听见。
4. If their numbers drop too low, it will bring danger to all ocean life. 如果它们的数目降至过低，会给所有海洋生物带来危险。
此句复数形式的number表达全海洋中鲨鱼的总量。当表示数值的高或低时，number要用high或low修饰。 e.g. In that country, the number of children going to school is higher in cities than in towns and village.
在那个国家，城市儿童入学人数比乡镇及农村要高。 常与number搭配的动词有grow, fall等。
e.g. The number of families that own cars has been growing quickly recently. 近来拥有轿车的家庭数量增长很快。
5. Environment protection groups around the world, such as WildAid and the WWF, are teaching the public about “finning”.

化而成，指课文中所陈述的 “猎翅”这一行为。
