VI.Languagepoints

1.Asharkcannolongerswimandslowlydies.鯊魚不能再游泳然后慢慢死掉。

nolonger意思是“不再”

e.g.I’mnolongerastudent.我不再是個(gè)學(xué)生了。

有兩個(gè)短語和nolonger同義，即not…anylonger和not…anymore，但他們側(cè)重的方面不同。

nolonger和not…anylonger側(cè)重時(shí)間。

e.g.Henolongerliveshere.=Hedoesn’tlivehereanylonger.

他不在這兒居住了。(一個(gè)時(shí)間以前他住在這兒，過了這個(gè)時(shí)間，他就離開了。)

not…anymore側(cè)重側(cè)重程度和數(shù)量

e.g.Youcandrinknomore.=Youcan’tdrinkanymore.

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。)

2.Thismethodisnotonlycruel,butalsoharmfultotheenvironment.這種方法不但殘忍而且對(duì)環(huán)境有害。

notonly…butalso…

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)可省略。

e.g.1)Shenotonlyplayswell,butalsowritesmusic.她不僅很會(huì)演奏，而且還會(huì)作曲。

2)Notonlymenbutalsowomenwerechosen.不僅僅是男的，女的也有被選中的。

若連接兩個(gè)成分作主語，其謂語通常與靠近的主語保持一致。

e.g.Notonlyyoubutalsohehastoleave.不只是你，他也得離開。

notonly放在句首，后接句子時(shí)要用倒裝結(jié)構(gòu)。

e.g.Notonlyhadthepoormanbeenfined,butalsohehadbeensenttoprison.

這個(gè)可憐的人不僅被罰款，而且還被送進(jìn)了監(jiān)獄。

beharmfulto對(duì)…有害

e.g.Smokingisharmfultothehealth.吸煙有損健康。

Playingcomputergamesmuchisharmfultostudents.電腦游戲玩太多對(duì)學(xué)生有害。

3.Sharksareatthetopofthefoodchainintheocean’secosystem.鯊魚位于海洋生物系統(tǒng)食物鏈的頂部。

Heshoutedatthetopofhisvoiceinorderthathemightbeheard.他盡力大聲叫喊,以便別人能聽見。

4.Iftheirnumbersdroptoolow,itwillbringdangertoalloceanlife.

如果它們的數(shù)目降至過低，會(huì)給所有海洋生物帶來危險(xiǎn)。

此句復(fù)數(shù)形式的number表達(dá)全海洋中鯊魚的總量。當(dāng)表示數(shù)值的高或低時(shí)，number要用high或low修飾。

e.g.Inthatcountry,thenumberofchildrengoingtoschoolishigherincitiesthanintownsandvillage.

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.Thenumberoffamiliesthatowncarshasbeengrowingquicklyrecently.近來擁有轎車的家庭數(shù)量增長(zhǎng)很快。

5.Environmentprotectiongroupsaroundtheworld,suchasWildAidandtheWWF,areteachingthepublicabout“finning”.世界各地的環(huán)境保護(hù)組織，如野生救援協(xié)會(huì)和世界自然基金會(huì)，都在教育公眾有關(guān)“獵翅”的行為。

1)句中fin本為名詞，指“魚鰭”。此句中的finning由動(dòng)詞化的fin（割鯊魚鰭以獲取魚翅）的-ing形式轉(zhuǎn)化而成，指課文中所陳述的“獵翅”這一行為。

2)WildAid和WWF組織

WildAid（美國(guó)野生救援協(xié)會(huì)）是保護(hù)野生動(dòng)物及棲息地環(huán)境的一個(gè)非盈利性的機(jī)構(gòu)，1999年注冊(cè)成立，其宗旨是保護(hù)及救助世界范圍內(nèi)的野生動(dòng)物；WWF（世界自然基金會(huì)）英文全稱為WorldWideFundforNature，成立于1961年，是享有國(guó)際盛譽(yù)，全球最大的獨(dú)立性非政府環(huán)境保護(hù)組織之一。

1.Rethink,Reuse,Recycle!

re-是最常用的前綴之一。它可以加在名詞或動(dòng)詞前面，構(gòu)成新的名詞或動(dòng)詞。re-表示以下三方面的意義：

1)表示“回”或“向后”的意思。例如：return（回來）recall（回憶，召回）retract（縮回，取回）

2)表示“再”、“重新”、“重復(fù)”的意思。

例如：rethink（再思考）reuse（再運(yùn)用）restart（重新開始）recycle

（再利用）

3)表示“相反”、“反對(duì)”的意思。

例如：rebel（反叛，謀反）reverse（反轉(zhuǎn)，顛倒）resist（反抗，抵抗）

2.Sheisamostunusualwoman.

un-前綴，常加在形容詞、副詞、分詞、動(dòng)詞和名詞之前；第一，表示否定意義。第二，表示“反動(dòng)作”。即“相反的動(dòng)作”。
