【语篇导读】本文是一篇说明文。文章介绍了关于防止信用卡被盗刷的一些注意事项及应对措施。1.F

上文“Many

victims

of

identity

theft

don’t

know

they

are

victims.”说明许多受害者并不知道自己就是受害者。F项“然而,有些迹象会提醒你,你就是其中之一”承接上文,转折语义。故选F项。2.A上文“In

this

case,you

should

call

the

police

right

away.”建议在这种情况下,要报警。A项“他们可能抓不到罪犯”承接上文,说明报警后的一种情况是,警察有可能抓不到罪犯,引出下文“But

it

puts

you

on

record

as

having

reported

the

identity

theft

and

can

help

in

repairing

your

credit.”转折说明,报警有可能抓不住罪犯,但是会把报警人记录下来,帮报警人修复信用。故选A项。ⅠⅡⅢⅣⅤⅥ3.D

下文“Not

receiving

your

mail

or

emails

related

to

expenses

is

a

red

flag

too.”介绍了另外一种身份盗窃的危险信号。D项承接本段小标题“You

stop

receiving

your

mail

or

emails”,说明你收到陌生的账单不是身份被盗窃的唯一危险信号,言外之意就是,还有其他危险信号。选项中“Receiving

strange

bills”和标题中“stop

receiving

your

mail

or

emails”语义相关,选项中dangerous

sign和下文中a

red

flag语义相关。故选D项。4.C

由下文“You

don’t

have

to

lose

your

wallet

for

thieves

to

steal...and

copy

your

credit

card

to

consume.”可知,本段介绍的情况是,要注意信用卡上不明原因的消费费用。C项概括了下文描述的这种情况,信用卡上有原因不详
