That'sall.Thankyou.答案以及解析1、答案：(1)(3)ABD解析：【文章大意】本文介紹了4個學(xué)英語的應(yīng)用程序。(1)A細(xì)節(jié)理解題。根據(jù)ItcanhelpusersbuildandtesttheirknowledgeofEnglishwordsandterms.得知Quizlet這款應(yīng)用可以幫助用戶增加詞匯量,故選A。(2)B細(xì)節(jié)理解題。根據(jù)Also,teacherscanuseSocrativeasan"exitticket",aquestiontheycanaskstudentsaboutwhattheylearnedinthatday'sclass.Studentswritetheiranswersontheirmobiledevices.Then,theteachercanshowtheanswersonasharedvideoscreen.得知,老師們在Socrative這款應(yīng)用上可以給學(xué)生們出題,營造"虛擬課堂"檢測學(xué)生的學(xué)習(xí)情況,故選B。(3)D推理判斷題。根據(jù)文章標(biāo)題FourappsforstudentstolearnEnglish得知本文是為了介紹四款學(xué)習(xí)應(yīng)用程序。故選D。2、答案：1.C;2.A;3.C;4.D解析：1.主旨大意題。由倒數(shù)第二段Salwen—家將大房子賣掉,換成只有原來面積一半的房子,然后將一半的利潤捐給了慈善機(jī)構(gòu),再結(jié)合最后一段Hannah和父親一起寫了thePowerofHalf這本書并提倡人們節(jié)省一半看電視的時間去幫助無家可歸的人可知,C項是最佳標(biāo)題。

2.推理判斷題。由一段中HannahSalwen所說的話可知,她認(rèn)為如果那個人沒有豪華轎車,這個無家可歸的人就會有頓飯吃,故可推知她對窮人懷有同情心。

3.細(xì)節(jié)理解題。從文章倒數(shù)第二段最后一句可知,HannahSalwen想賣房子的原因是她想做慈善,幫助社會上的窮人。

4.詞義猜測題。根據(jù)文章倒數(shù)第二段及常識分析,母親一開始僅僅是開玩笑。3、答案：1.C;2.D;3.A;4.C解析：1.C主旨大意題。作者在本文第一段中就提出了主題,然后下文圍繞這一主題進(jìn)行深入闡述,即“語言學(xué)習(xí)可以提高你的智力”。2.D推理判斷題。作者在第二段中把語言學(xué)習(xí)對大腦的促進(jìn)作用比作體育鍛煉對強(qiáng)健肌肉的促進(jìn)作用,也就是說語言學(xué)習(xí)對大腦有類似的促進(jìn)作用。再根據(jù)“Researchers...changesgreymatter.Thisistheareaofthebrainwhichprocessesinformation.”可知,語言學(xué)習(xí)對大腦的促進(jìn)作用表現(xiàn)在改變greymatter上。3.A推理判斷題。根據(jù)第五段可推出答案。4.C詞義猜測題。根據(jù)該詞后“whohadlearntasecondlanguagebeforetheageoffive”可得出答案。4、答案：1.C;2.A;3.C;4.D

解析：1.細(xì)節(jié)理解題。依據(jù)第一段Thisseriesofactionsissomonthatyouprobablydonotpayitmuchattention.ButUniversityofManchesterbioinechanicalengineerBenParslewdoes.Heistryingtodesignrobotsthatcanjumplikebirds.可知,鴿子起飛時一系列動作給曼徹斯特大學(xué)生物力學(xué)工程師本·帕爾斯特以啟發(fā),嘗試設(shè)計能像鳥一樣跳躍的機(jī)器人。故選C。

2.推理判斷題。依據(jù)第二段Mostconventionalrobotsrollaroundonwheels,limitingmobility.Thereisaneedformoreagilerobotsthat"canjumpoverobstaclesinmessyenvironments,"Parslewsays.可知,大多數(shù)傳統(tǒng)的機(jī)器人都是靠輪子滾動的,這限制了它們的機(jī)動性,不能夠在混亂的環(huán)境中跳過障礙。從而推測,傳統(tǒng)的機(jī)器人是不能夠跳越障礙的。故選A。

3.細(xì)節(jié)理解題。依據(jù)第三段Theydiscoveredthatbirdstwisttheirbodiesslightlytowardsthebackwhileacceleratingintoajump.Theyalsohaveflexiblelegsandtoejoints,whichpreventthemfromtakingoffbrieflyandimmediatelycrashingintotheground.他們發(fā)現(xiàn),鳥類在加速跳躍時,身體會向背部輕微扭轉(zhuǎn),并且有靈活的腿和腳趾關(guān)節(jié),從而避免墜落。故選C。

4.主旨大意題。綜合文章第一段Heistryingtodesignrobotsthatcanjumplikebirds.后及最后一段可知,文章主要介紹通過研究鳥類跳躍,有助于科學(xué)家制造更好的機(jī)器人。故選D。5、答案：

1.G

2.F

3.C

4.D

5.E

解析：1.由前句Ifyouarelookingtopursueyourdreams,itcanbediscouragingtochangeeverythingatonce.可知此處應(yīng)該是表示轉(zhuǎn)折的,相反,如果不那樣,會??????。2.由Don'tleaveanythingout,nomatterhowsmallorsillyitsounds.可知此處應(yīng)該是列出你想實(shí)現(xiàn)的事情。3.根據(jù)下文Chooseonethatisrelativelyeasytoacplish,onethatisdoablebutwillrequireworkandonethatseemsimpossiblebasedonyourcurrentcircumstancesandlifestyle.可知此處應(yīng)為有關(guān)三件事情的描述。4.由下文Eachtimeyoupleteoneofthesteps,crossitoffsoyoucancelebratetheprocessinadditiontotheendresult.以及關(guān)鍵詞plete可知此處應(yīng)為從最小的目標(biāo)開始去實(shí)現(xiàn)它。5.由最后一句Planyourstepslikethisandtheywillbedoableandfitsmoothlyintoyourlife.可知此處應(yīng)為為每個目標(biāo)都要規(guī)定截止日期,按計劃去做。6、答案：1.C;2.D;3.A;4.C;5.D;6.B;7.C;8.A;9.D;10.C;11.B;12.A;13.D;14.C;15.A;16.B;17.C;18.B;19.D;20.C

解析：1.老太太和作者是大學(xué)同學(xué),一起下課。句意:在此后的三個月中,我們每天都一起離開課堂,聊起來沒完沒了.

2.sharesth.withsb.和……一起分享。句意:當(dāng)她和我分享她的智慧和經(jīng)驗時,我總是在聽這個“時間機(jī)器。"

3.根據(jù)4空前的deliverherpreparedspeech提示得出答案,句意:學(xué)期末,我們邀請羅絲向我們的足球隊發(fā)表演講。

4.句意:當(dāng)她開始進(jìn)行準(zhǔn)備好的演講時,她把卡片掉在了地板上.

5.演講時把卡片掉到地板上,當(dāng)然有點(diǎn)尷尬。

6.inorder”按順序”;inchaos“"混亂”;inadvance”預(yù)先,提前”;insilence“"沉默地”。句意:我再沒辦法按準(zhǔn)備好的順序進(jìn)行演講了,那我就說一說我知道的吧.

7.clearone'sthroat清清嗓子”;cleanonesthroat"清理嗓子”;cutone'sthroat"自食惡果”;forceonesthroat""強(qiáng)迫接受(觀點(diǎn))”,句意:我們都笑了,她則清了清嗓子開始說道:“我們不踢球了并不是因為自己老了".

8.句意:我們不踢球了并不是因為老了,我們變老了是因為我們不再踢球了。not.because表示否定轉(zhuǎn)移,意思為“不是因為……而...".

9.根據(jù)上句,我們不再踢球了,所以老了。那么要讓自己不變老,就必須保持年輕。句意:只有四個秘訣讓自己保持年輕、快樂和成功.

10.前一句告訴聽眾必須要有夢想,后一句則說,失去了夢想,人就死了。句意:一定要有夢想。一旦失去夢想,人就死了.

11.根據(jù)前一句中的die得知。句意:在我們周圍有那么多行尸走肉般的人,他們自己卻不知道.

12.growup長大,句意:變老和長大有很大的區(qū)別。

13.前面提到變老與長大的區(qū)別,變老很容易,在床上躺一年也能變老,而長大則要做些有益的事。句意如果你19歲,在床上躺上整整一年,卻不做一件有益的事情,你也會長到20歲.

14.turn:toreachorpassaparticularageortime變成,達(dá)到(年齡)。句意:如果你19歲,在床上躺上整整年,卻不做一件有益的事情,你也會長到20歲.

15.not...butrather”不是…l是…but表示轉(zhuǎn)折,rather起強(qiáng)調(diào)的作用。句意:老年人通常不會為我們所做的事后悔,而會為我們沒有做的事后悔.

16.根據(jù)14空后的Havenoregrets.得出答案。句意:只有那些有遺憾的人才會怕死.

17.據(jù)后句的aftergraduation得知,老太太完成了大學(xué)學(xué)業(yè),句意:年帳的時候,羅絲獲得了大學(xué)學(xué)位.

18.老太太獲得了大學(xué)學(xué)位,實(shí)現(xiàn)了夢想,沒有留下遺憾,所以走的時候應(yīng)該是平靜地。句意:畢業(yè)一周之后,羅絲在睡夢中平靜地去世.

19.老太太以高齡學(xué)生的身份完成了大學(xué)學(xué)業(yè),學(xué)生們參加她的葬禮就是為了紀(jì)念她。句意:兩千多名大學(xué)生參加了她的葬禮,以紀(jì)念這位了不起的女性.

20.atrandom“隨便地”byexample舉例,例子”;atcase自由自在”;bychance“偶然,碰巧”。句意:這位了不起的女性以自身為榜樣教育我們:竭盡所能,活到老學(xué)到老.7、答案：the；them；voyages；learning；rapidly；as；wasbased；because；enriched；that/which解析：1.【解題思路】考查冠詞。attheendof...“在……結(jié)尾”，為習(xí)慣搭配。

2.【解題思路】考查代詞。由空前的of可知，此處應(yīng)該用賓格them,指代的是上句中的"aboutfivetosevenmillionpeople"。

3.【解題思路】考查名詞復(fù)數(shù)。分析句子結(jié)構(gòu)可知，此處應(yīng)填名詞，因voyag
