Unit13Wearetryingtosavetheearth.

SectionA3a-3b自治区、直辖市重点保护野生动物名目还有成百上千种。伴随经济连续快速发展和生态环境日益恶化，我国濒危动物种类还会增加。改革开放以来，我国进口了不少动物，如湾鳄、暹罗鳄、食蟹猴、黑猩猩、非洲象等。至于我国终究有多少种濒危动物极难说清。但能够必定，假如包含无脊椎动物话，最少有1000种。Animalsareourfriends.Weliveinthesamesmallworld.Toloveanimalsistoloveourselves.Someanimalsareendangered.Weshoulddosomethingtoprotecttheanimalsandtheenvironment!

科学上，科学1.Asharkcannolongerswimandslowlydies.鲨鱼不能再游泳然后慢慢死掉。nolonger意思是“不再”e.g.

I’mnolongerastudent.

我不再是个学生了。有两个短语和nolonger同义，即not…anylonger和not…anymore，但他们侧重方面不一样。Languagepoints2.Thismethodisnotonlycruel,butalso

harmfultotheenvironment.

这种方法不但残忍而且对环境有害。notonly…butalso…用于连接两个表示并列关系成份，着重强调后者，其意为“不但……而且……”;其中also有时能够省略。e.g.Shenotonlyplayswell,butalsowritesmusic.

她不但很会演奏，而且还会作曲。

Notonlymenbutalsowomenwerechosen.

不但仅是男，女也有被选中。若连接两个成份作主语，其谓语通常与靠近主语保持一致。e.g.Notonlyyoubutalsohehastoleave.

不只是你，他也得离开。

notonly放在句首，后接句子时要用倒装结构。e.g.Notonly

hadthepoormanbeenfined,butalsohehadbeensenttoprison.

这个可怜人不但被罚款，而且还被送进了监狱。

beharmfulto对……有害e.g.Smokingisharmfultothehealth.

吸烟有害健康。

Playingcomputergamesmuchisharmfultostudents.

电脑游戏玩太多对学生有害。3.Sharksareatthetopofthefoodchainintheocean’secosystem.

鲨鱼位于海洋生物系统食物链顶部。atthetopof

在……最高地位;用最高[最大](速度,声音等)e.g.Heshoutedatthetopofhisvoiceinorderthathemightbeheard.他尽力大声叫喊,方便他人能听见。4.Iftheirnumbersdroptoolow,itwillbringdangertoalloceanlife.

drop（n.滴；落下；vt.滴；使降低；vi.下降；终止）假如它们数目降至过低，会给全部海洋生物带来危险。此句复数形式numbers表示全海洋中鲨鱼总量。当表示数值高或低时，number要用high或low修饰。fall不及物动词，落下、掉下之意；而drop是及物动词，扔下，使掉下之意。如:Thestonefell

downontohisfeet.Hedroppedthestoneontohisownfeet.e.g.Inthatcountry,thenumberofchildrengoingtoschoolishigherincitiesthanintownsandvillage.

在那个国家，城市儿童入学人数比乡镇及农村要高。常与number搭配动词有grow,fall等。e.g.Thenumberoffamiliesthatowncars

hasbeengrowingquicklyrecently.

最近拥有轿车家庭数量增加很快。5.Environmentprotectiongroupsaroundtheworld,suchasWildAidandtheWWF,areteachingthepublicabout“finning”.

世界各地环境保护组织，如野生救援协会和世界自然基金会，都在教育公众相关“猎翅”行为。1)句中fin本为名词，指“鱼鳍”。此句中finning由动词化fin（割鲨鱼鳍以获取鱼翅）-ing形式转化而成，指课文中所陈说“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一个非盈利性机构，1999年注册成立，其宗旨是保护及救助世界范围内野生动物；WWF（世界自然基金会）英文全称为WorldWideFundforNature，成立于1961年，是享受国际盛誉，全球最大独立性非政府环境保护组织之一。II.单项选择。1.—Areyougoingto_____anyoftheevents?—Yes.Maybelongjumpandhighjump.
