Homework
Listen and underline the language points.
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.
這種方法不但殘忍而且對(duì)環(huán)境有害。
not only…but also… 用于連接兩個(gè)表示并列關(guān)系的成分，著重強(qiáng)調(diào)后者，其意為“不僅……而且……”; 其中的also有時(shí)可以省略。
e.g. She not only plays well, but also writes music.她不僅很會(huì)演奏，而且還會(huì)作曲。
若連接兩個(gè)成分作主語(yǔ)，其謂語(yǔ)通常與靠近的主語(yǔ)保持一致。
e.g. Not only you but also he has to leave. 不只是你，他也得離開(kāi)。
not only放在句首，后接句子時(shí)要用倒裝結(jié)構(gòu)。
e.g. Not only had the poor man been fined, but also he had been sent to prison.
這個(gè)可憐的人不僅被罰款，而且還被送進(jìn)了監(jiān)獄。
no longer意思是“不再” e.g. I’m no longer a student. 我不再是個(gè)學(xué)生了。
有兩個(gè)短語(yǔ)和no longer同義，即not…any longer和not…any more，但他們側(cè)重面不同。
no longer和not…any longer側(cè)重時(shí)間
e.g. He no longer lives here.= He doesn’t live here any longer.
他不在這兒居住了。(一個(gè)時(shí)間以前他住在這兒，過(guò)了這個(gè)時(shí)間，他就離開(kāi)了。)
not…any more側(cè)重側(cè)重程度和數(shù)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，不能再繼續(xù)下去了。)
A shark can no longer swim and slowly dies.
鯊魚(yú)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.
鯊魚(yú)位于海洋生物系統(tǒng)食物鏈的頂部。
at the top of 在...最高地位; 用最高[最大]的(速度, 聲音等)
e.g. I looked at the top of his head, his hair shiny and parted smoothly.
我看他的頭頂, 頭發(fā)光亮, 分得平滑。
He shouted at the top of his voice in order that he might be heard.
他盡力大聲叫喊, 以便別人能聽(tīng)見(jiàn)。
If their numbers drop too low, it will bring danger to all ocean life.
如果它們的數(shù)目降至過(guò)低，會(huì)給所有海洋生物帶來(lái)危險(xiǎn)。
此句復(fù)數(shù)形式的number表達(dá)全海洋中鯊魚(yú)的總量。當(dāng)表示數(shù)值的高或低時(shí)，number要用high或low修飾。
e.g. In that country, the number of children going to school is higher in cities than in towns and village. 在那個(gè)國(guó)家，城市兒童入學(xué)人數(shù)比鄉(xiāng)鎮(zhèn)及農(nóng)村要高。
常與number搭配的動(dòng)詞有g(shù)row, fall等。
e.g. The number of families that own cars has been growing quickly recently.
近來(lái)?yè)碛修I車(chē)的家庭數(shù)量增長(zhǎng)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!
Listen and underline the language points.
