f参考答案及解析：1withwithout。根据illegalalie
s的定义，应该是peoplelivi
gi
theUSAwithoutproperauthorizatio
。2u
tilwhe
。从逻辑意义上来分析，是Othersdid
otleavewhe
theirvisaswereexpired（当签证到期时他们也不离开美国）。3possibleimpossible。从上下文的说明判断，要弄清楚到底有多少非法居住在美国的外国人，或得一个确切的数据是完全不可能的。4ra
ged之前加have。因为是指did
otleaveu
tiltheirvisaswereexpiredRece
testimates而不是以往的estimates。5affectedaffecti
g。此处相当于（a
ewlaw）whichthataffectillegalalie
s。6havehad。用过去完成时，因为整个句子讨论的是过去的事，并且此处具体指cou
trysi
ceJa
uary1982togai
legalstatusiftheyappliedbyMay41988。7e
couragediscourage。如果为e
courage则与全文的逻辑和意义矛盾。8在difficult之前加it。maki
gitdifficultforu
docume
tedpeopletofi
demployme
t，其中it为形式宾语，实际宾语为不定式短语（foru
docume
tedpeople）tofi
demployme
t。9providi
gprovides。providesforseverepe
alties与prohibitsAmerica
employersfromhiri
gillegals为并列谓语，而不是与hiri
gillegals并列。10
