1.A shark can n lnger swim and slwly dies. 鲨鱼不能再游泳然后慢慢死掉。
【解读】n lnger意思是“不再”有两个短语和n lnger同义，即nt…any lnger和nt…any mre，但他们侧重的方面不同。
e.g.I’m n lnger a student. 我不再是个学生了。 Yu can drink n mre. = Yu can’t drink any mre. 你不能再喝了。
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。
【解读1】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. 1) She nt nly plays well, but als writes music. 她不仅很会演奏，而且还会作曲。 2) 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。
【解读2】 harmful/'hɑː(r)mfl/ adj.有害的。 harmful可用作表语和定语，常用于be harmful t“对……有害”这个结构中。注意：harmless adj.无害 harm n. /v.伤害 d harm t 对……有害e.g. Eating t much candy is harmful t yur teeth. 吃太多的糖对你的牙齿有害。That will d harm t yur study.那对你的学习不利。
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。
at the tp f 还可表示“(速度, 声音等) 达到极限；（地位、名次）达到最高。e.g. She ran at the tp f her speed.她以自己最快的速度跑。
He shuted at the tp f his vice in rder that he might be heard.他尽力大声叫喊, 以便别人能听见。
【解读】at the tp f 在的顶部
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。
【解读】 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lw修饰。
e.g. In that cuntry, the number f children ging t schl is higher in cities than in twns 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。
