B.Trafficaccidents.C.Badweathers. D.Naturaldisasters.答案A

解析

词义猜测题。根据画线词上文“our

area

had

just

been

in

the

path

of

Hurricane

Irma,causing

downed

trees”及下文“We

were

stuck

in

the

dark

and

cut

off

from

the

outside

world.”可知,作者和丈夫所在的地区刚刚受到飓风“厄玛”的袭击,导致树木倒塌,他们被困在黑暗中,与外界失去联系。由此推知,画线词outages与A项Power

cuts意思接近,意为“停电”。故选A项。ⅠⅡⅢⅣⅤⅥⅦ2.Whatisthethirdparagraphmainlyabout?A.Theimportanceofstoringupdailygoods.B.Theexperienceofdealingwithhousework.C.Theitemstheauthorboughtforherdailylife.D.Thepreparationstheauthormadeforemergency.答案D

解析

主旨大意题。通读第三段可知,经历了以前的暴风雨之后,作者随时准备着照明用的东西、电池,还有烤架、食物,汽车油箱也加满了油,手头还有应急现金。由此可知,第三段主要讲述了作者为以后的暴风雨所做的准备。ⅠⅡⅢⅣⅤⅥⅦ3.Whatdoestheauthorthinkofexperiencingthepaststorms?A.Itwassatisfactory. B.Itwasinstructive.C.Itwasunforgettable. D.Itwasunbearable.答案B

解析

推理判断题。根据第四段中的“but

we

wouldn’t

have

learned

to

do

all

those

things

if

we

hadn’t

encountered

a

storm

in

the

past(但如果我们过去没有遇到风暴,我们就不会学会做所有那些事情)”以及“They

can

teach

us

some

valuable

lessons.(他们可以教给我们一些宝贵的经验。)”可推知,作者认为曾经经历过的暴风雨对他们是有益的。ⅠⅡⅢⅣⅤⅥⅦ4.Whatcanwelearnfromtheauthor’sstory?A.Whenitrains,itpours.B.Wherethere’ssmoke,there’sfire.C.Strikewhiletheironishot.D.Takeprecautionsbeforeitistoolate.答案D

解析

推理判断题。根据最后一段中的“Now

is

the

time

to

get

ready...not

when

the

storm

arrives.”可知,作者认为现在要为以后的暴风雨做准备,而不是当暴风雨来临的时候才准备。由此推知,作者的故事告诉我们一定要未雨绸缪。ⅠⅡⅢⅣⅤⅥⅦⅤ.七选五(2023·山东聊城高一期中)Sportsday!Thesetwowordscaninspirebothjoyandfearintheheartsofstudentseverywhere.

根据上文可知,本段会介绍喜欢运动和恐惧运动的人。下文介绍了恐惧运动的人,由此可知,空处应是介绍喜欢运动的人。C项“For

many,sports

day

can

be

a

great

day

of

fun.(对许多人来说,运动会可以是很有趣的一天。)”符合文意。2.E

上文讲非竞争性运动让所有孩子不必担心失败,尽情地运动,这是它的益处。E项“Everyone

should

be

celebrated

for

trying

and

playing

their

part.(每个人都应该为自己的努力和发挥作用而庆祝。)”承接上文,讲出了非竞争性运动给孩子带来的益处。ⅠⅡⅢⅣⅤⅥⅦ3.A

由上文“However,some

people

feel

that...important

as

learning

how

to

win.”可知,本段讲的是赢的重要性。A项“What’s

the

point

if

no

one

wins?(如果没有人赢,那有什么意义?)”体现了对赢的看重。4.F

本段是在讲大部分人都同意上文提到的观点,特别是父母,所以F项“There

are

lots

of

people

who

agree

with

the

idea—parents

in

particular!(有很多人同意这个想法——尤其是父母!)”符合文意。5.D

根据后文“We

want

to

know

your

ideas.(我们想知道你的想法。)”可推断,空处应是提了一个问题。所以D项“So,should

school

sports

days

be

competitive

or

not?(那么,学校运动会是否应该是竞争性的呢?)”符合语境。ⅠⅡⅢⅣⅤⅥⅦⅥ.应用文写作假定你是李华,你的美国笔友Peter看见了中国某地发生特大洪水的新闻,给你写邮件询问政府和人民是如何应对自然灾害的。请你用英语给他回一封邮件,内容包括:1.政府组织救援及医护人员救灾,并及时运送救援物资;2.人民群众自发捐款捐物。注意:1.词数80左右;2.可以适当增加细节,以使行文连贯;3.邮件的开头和结尾已给出,不计入总词数。ⅠⅡⅢⅣⅤⅥⅦDearPeter,I’mgratefulbecauseyou’reconcernedaboutthefloodinChina._________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Thatishowwefacenaturaldisastersasabigfamily.Yourssincerely,LiHuaⅠⅡⅢⅣⅤⅥⅦDearPeter,
