1. A shark can n lnger swim and slwly dies. 鲨鱼不能再游泳然后慢慢死掉。
n lnger意思是“不再” e.g. I’m n lnger a student. 我不再是个学生了。
有两个短语和n lnger同义，即nt…any lnger和nt…any mre，但它们侧重的方面不同。
n lnger和nt…any lnger侧重时间。 e.g. He n lnger lives here. = He desn’t live here any lnger. 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。) nt…any mre侧重程度和数量e.g. Yu can drink n mre. = Yu can’t drink any mre. 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 methd is nt nly cruel, but als harmful t the envirnment. 这种方法不但残忍而且对环境有害。
nt nly…but als…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als有时可以省略。
e.g. She nt nly plays well, but als writes music. 她不但很会演奏，而且还会作曲。 Nt nly men but als wmen were chsen. 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. Nt nly yu but als he has t leave. 不只是你，他也得离开。
nt nly放在句首，后接句子时要用倒装结构。 e.g. Nt nly had the pr man been fined, but als he had been sent t prisn.这个可怜的人不仅被罚款，而且还被送进了监狱。
be harmful t 对……有害e.g. Smking is harmful t health. 吸烟有害健康。 Playing cmputer games tmuch is harmful t students.电脑游戏玩太多对学生有害。
3. Sharks are at the tp f the fd chain in the cean’s ecsystem. 鲨鱼位于海洋生物系统食物链的顶部。

4. If their numbers drp t lw, it will bring danger t all cean 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numbers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lw修饰。
e.g. In that cuntry, the number f children ging t schl is higher in cities than that in twns and villages. 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grw, fall等。e.g. The number f families that wn cars has been grwing quickly recently. 近来拥有轿车的家庭数量增长很快。
5. Envirnmental prtectin grups arund the wrld, such as WildAid and the WWF, are teaching the public abut “finning”. 世界各地的环境保护组织，如野生救援协 会和世界自然基金会，都在教育公众有关 “猎翅”的行为。1) 句中fin本为名词，指 “鱼鳍”。此句中的 finning由动词化的fin（割鲨鱼鳍以获取 鱼翅）的-ing形式转化而成，指课文中所 陈述的 “猎翅”这一行为。
2) WildAid和WWF组织 WildAid（美国野生救援协会）是保护野生动物及栖息地环境的一个非盈利性的机构，1999年注册成立，其宗旨是保护及救助世界范围内的野生动物；WWF（世界自然基金会）英文全称为Wrld Wide Fund fr Nature，成立于1961年，是享有国际盛誉，全球最大的独立性非政府环境保护组织之一。
