(2)Peoplewhofindhibernatinganimalsasleepoftenthinkthattheyaredead.

  (3)Youcantouchit,orevenpullitstail,withoutcausingittomoveorwakeup.

  (5)Thesecondisconnectedwiththemainusethebodymakesoffood—tosupplytheenergyformovements.

  (6)Wehaveseenthathibernatinganimalreducesmovementstofarbelowtheordinarylevel.

  (7)Theanimalhardlymakesanymovement,hardlyusesanyenergy,andhardlyneedsanyfood.

  (8)Someanimals,includingsomebears,onlyhalf-hibernate.

  难句解析:

  1.Theygotosleepinallkindsofplaces.它们到各种各样的地方去睡觉。

  gotosleep,fallasleep与sleep,这三个词(组)都有“睡着”之意。

gotosleep意思是“睡着,去睡觉”,fallasleep意思是“睡着了,酣睡”,它们都表瞬间动作,如表持续性动作或延续性状态,要用动词sleep。

e.g.

  ①Ifounditverydifficulttogotosleep.我发现很难人睡。

  ②Soonhefellasleep,forhewasverytired.他很累,很快就睡着了。

  ③wehaveslept(for)eighthours.我们已睡了八个小时。

  2.Theyleadanactivelifewhichkeepsuptheirbodytemperatureeveninverycoldwinterweather.

  他们生活得很活跃,即使在严寒的冬天也能保持正常的体温。

  习惯用法

  

(2)keepup保持,维持,继续,e.g.

  ①LetshopethesunnyweatherkeepsupforSaturdaystennismatch.

  但愿星期六网球比赛时还是这样的好天气。

  ②We。

Arehavingdifficultykeepingup。

our。

mortgagepayments.我们难以继续支付分期偿还的抵押货款。

  ③Ifyouwanttobeaperformer,you11havetokeepupyourpiano.如果你真想成为演奏家,就得坚持练习钢琴.

  3.Thenitasnochoicebuttoliedownandsleep.于是,别无选择,它们只好躺下睡觉。

  havenochoicebuttodo表“别无选择”之意。

e.g.

  HaveIanychoicebuttodoasyoutellme?

除了按你吩咐的去做外,我还有别的选择吗?

  表示“别无选择只好做……”之意,除了可用havenochoicebuttodo…来表达外,还可用下列固定搭配:

  (l)candonothingbutdo/cannotdoanythingbutdo,e.g.

  Icandonothingbutaccepthisdemand.我只好接受他的要求。

  

(2)thereisnothinglefttodobutdo…,e.g.

  Therewasnothingleftforhertodobutcry.她别无它法,只有哭。

  (3)can’tbutdo…,e.g.

  Icouldnotbutadmitthathewasrightand。

Iwaswrong.我不得不承认他对了,我错了。

  疑难点拨:

  1.Hibernationismorethansleep.冬眠不仅仅是睡眠。

  句中的morethan相当于notonly。

意为“不仅仅”。

e.g.

  Heis。

moreateacher.Heisagoodfriendofmine。

他不只是老师,还是我的益友。

  2.Peoplewhofindhibernatinganimalsasleepoftenthinkthattheyaredead..人们看到处于冬眠状态的动物,常常以为它们死了。

  这是一个复合句。

  (l)who-clause是定语从句修饰people,that-clause是宾语从句作think的宾语。

  

(2)asleep是表语形容词,在句中一般只作表语,宾补,或后置定语,这样的形容词还有alive,alike,alone,awake等。

  3.Youcantouchit,orevenpullitstailwithoutcausingittomoveorwakeup.你可以摸它,甚至可以拉它的尾巴,这也不会使它动一动或醒过来。

  这个句子可改写成:

Evenifyoutouchitorpullitstail,youcan’tcauseitmoveorwakeup.

  4.Hibernatinginthatway,theanimalcansleepallthroughthewinter.

  用那种方式冬眠,动物可以睡过整过冬天。

  句中的hibernatinginthatway是现在分词短语在句中作状语,相当于astheyhibernateinthatway。

  5.Wehaveseenthathibernatinganimalreducesmovementstofarbelowtheordinarylevel..

  冬眠动物的活动量减少到远远低于一般水平。

  

(1)句中的farbelow意为“远远低于,比……低得多”。

e.g.

  InwinterthetemperatureofHarbinisfarbelowthatofWuhan.

  冬天哈尔滨的气温比武汉的低得多。

  

(2)句中的reduce..to作“减少,使处于……状态”解。

e.g.

  ①Thehousewasreducedtoashesbythebigfire.那场大火把屋子化为灰烬。

  ②Themanwasreducedtobeggingforfood.那男人沦落到讨饭的地步。
