略讀時(shí)，只需讀每一段第一句話(huà)（較長(zhǎng)的段落，讀前兩句）。第一句話(huà)常是整段討論的主題。在結(jié)論段，重點(diǎn)可能在最后一句。閱讀時(shí)，把文本標(biāo)出來(lái)，是幫助回答問(wèn)題好方法。可將關(guān)鍵詞畫(huà)線(xiàn)或在段落旁寫(xiě)下本段主題，一兩個(gè)字就夠了，關(guān)鍵在于涵蓋全文的速度。

略讀時(shí)遇到不懂單詞，試觀察前后字來(lái)猜出意思。比如，在不懂的單字前面是形容詞，那么這個(gè)字可能會(huì)是名詞；在不懂的單字之前是副詞，那么這個(gè)字可能會(huì)是動(dòng)詞。只要了解段落大意就好了。Itis8:30a.m.attheChengduResearchBase.Pandakeepersarepreparingmilkforthebabypandas'breakfast.At9:00a.m.,theyfindthatmostofthebabiesarealreadyawakeandhungry.Whenthebabiesseethekeepers,theyrunovertothemwithexcitementandsomeoftheyoungpandasevenwalkintotheirfriendsandfallover!LinWei,oneofthepandakeepers,says,"They'resocuteandlovely.Itakecareofthemlikethey'remyownbabies.Iwash,feedandplaywiththemeveryday.They'reveryspecialtome."Infact,manypeoplearoundtheworldlovetheseblackandwhiteanimals.PandashavebecomesopopularthattheyarenowasymbolofChina.Scientistssaytherearenowfewerthan2,000pandaslivingintheforests.Another300orsoliveinzoosorresearchcentersinChinaandothercountries.Pandasdonothavemanybabies,maybeonlyoneeverytwoyears.Thebabiesoftendiefromillnessesanddonotliveverylong.Adultpandasspendmorethan12hoursadayeatingabout10kilosofbamboo.Manyyearsago,therewerealotmorebambooforestsandpandasinChina,butthenhumansstartedtocutdowntheseforests.Astheforestsgetsmallerandotherhumanactivitiescausemoreproblems,pandascannotfindenoughtoeatandtheyarehavingfewerbabies.AneducationprograminChengduteacheschildrenaboutpandasandotherendangeredwildanimals.Theysendpeopletoschoolstotellchildrenabouttheimportanceofsavingtheseanimals.AndtheChinesegovernmentistryinghardtohelpsavethepandas.Scientistsaredoingresearchtobetterunderstandthehabitsofpandas.Weallhopethatinthefuturetherewillbealotmorepandas.2cReadthearticleagainandwriteshortanswerstothequestions.WhatisLinWei'sjob?

鯨的體型是世界上存在的動(dòng)物中最大的，鯨是終生生活在水中的哺乳動(dòng)物，對(duì)水的依賴(lài)程度很大，以致它們一旦離開(kāi)了水便無(wú)法生活，鯨形狀像魚(yú)，鼻孔在頭的上部，用肺呼吸。體長(zhǎng)可達(dá)三十米，是現(xiàn)在世界上最大的動(dòng)物。Doyouknow?

鯨為適應(yīng)水中生活，減少阻力，它們的后肢消失，前肢變成劃水的漿板。身體成為流線(xiàn)型，酷似魚(yú)。因而它們的潛水能力很強(qiáng)，小型齒鯨可潛至100-300米的水深處，停留4-5分鐘，長(zhǎng)須鯨可在水下300-500米處待上1小時(shí)，最大的齒鯨--抹香鯨能潛至千米以下，并在水中持續(xù)2小時(shí)之久。3aReadthefollowingwordsandphrasesaboutwhales.Puttheminthecorrectplaceinthechart.123456789101112Whatdotheylooklike？Wheredotheylive?Whatdotheyeat?Whatcantheydo?Whydosomeofthemhavetobeprotected?Howcanweprotectedthem?5872311161249103bWriteaparagraphaboutwhalesandwhytheyneedtobeprotected.Usetheinformationin3a.Thenmakeaposter.Whalesare…Theylivein…Theyeat…Theycan…Oneinterestingfactis…Anotherinterestingfactis…Somekindsofwhalesareindangerbecause…Weshouldprotectwhalesfrom…Ithinkpeopleshould/shouldn’t…

shakeherawake.你得把她給搖醒。Keypoints另外，awake不與very搭配使用，表示“完全醒來(lái)；十分清醒”用fullyawake，wideawake。Hewas

wideawake

bythetimewereachedmyflat.等我們到達(dá)我的住所時(shí)，他已經(jīng)完全清醒過(guò)來(lái)了。注意：awake不用于名詞之前，因此用作定語(yǔ)時(shí)要后置。1)

10kilosofbamboo意為“10公斤竹子”，該結(jié)構(gòu)是不可數(shù)名詞量的表達(dá)法，其結(jié)構(gòu)為“數(shù)詞+單位名詞+of+名詞”。單位名詞可以是單數(shù)，也可以是復(fù)數(shù)。2)spend…(in)doingsth.意為“花費(fèi)……做某事”。They

spenttwoyears

(in)building

thisbridge.造這座橋花了他們兩年時(shí)間。2.Adultpandasspendmorethan12hoursadayeatingabout10kilosofbamboo.SelfCheck1.Completethechart.AdjectivesComparativesSuperlativeshighdangerouslongpopularhigherhighestmoredangerousmostdangerouslongerlongestmorepopularmostpopular2.Matchverbsandobjects.Thenaddonemoreobje
