Homework

Save the Sharks!
Many have heard of shark fin soup. But do you realize that you’re killing a whole shark each time you enjoy a bowl of shark fin soup
Listen and underline the language points.
When people catch sharks, they cut off their fins and throw the sharks back into the ocean. This is not only cruel, but also harmful to the environment. Without a fin, a shark can no longer swim and slowly dies. Sharks are at the top of the food chain in the ocean’s ecosystem. If their numbers drop too low, it will bring danger to all ocean life. Many believe that sharks can never be endangered because they are the strongest in their food chain. But in fact, around 70 million sharks are caught and traded in this industry every year. The numbers of some kinds of sharks have fallen by over 90 percent in the last 20 to 30 years.
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. She not only plays well, but also writes music.她不仅很会演奏，而且还会作曲。
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。
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。)
A shark can no longer swim and slowly dies.
鲨鱼不能再游泳然后慢慢死掉。
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。
at the top of 在...最高地位; 用最高[最大]的(速度, 声音等)
e.g. I looked at the top of his head, his hair shiny and parted smoothly.
我看他的头顶, 头发光亮, 分得平滑。
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。
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。
Environmental protection groups around the world, such as WildAid and the WWF, are teaching the public about “finning”. They have even asked governments to develop laws to stop the sale of shark fins. So far, no scientific studies have shown that shark fins are good for health, so why eat them Help save the sharks!
