members
and
friends
get
together
for
a
dinner.
People
sometimes
drive
their
cars
a
long
way
for
a
family
reunion(团聚).
Many
people
also
take
Friday
off
and
make
it
a
long
weekend
holiday,
because
most
Americans
do
not
work
on
Saturdays
and
Sundays.
Thanksgiving

the
second
year
after

They
decided
to
invite
their
Indian
friends
to
a
dinner
in
order
to(为了)thank
them
for
their
help
and
God.
As

at敲...。所以答案为:knocked
at。
37.After
all
【解析】
after
all“别忘了……,”“总之....”“毕竟”,这时的after
all一般故在句首,用来提醒对方(听话的人)似乎忘记了一个重要事实,忽略了某个重要的理由或论点。所以答案为:After
all。
38.take

【解析】
动词短语take
off,起飞、脱下;本句为祈使句,please后跟动词原形。所以答案为:take
off。

all
【解析】
毕竟after
all,固定短语,故填after
all。
40.making/having
effort
【解析】
make/have
an
effort“做出努力”,是固定短语,without是介词,后接doing形式,所以make/have要用making/having,故填making/having,effort。
41.illness
42.angrily
43.taught
44.third
45.except
【分析】
41.
句意:他的身体不适是在晚上吃东西的结果。分析句子结构可知,此空需用名词形式;由“eating
something
overnight.”可知,这种行为导致的结果是生病,ill的名词为illness意为“身体不适”,不可数名词。故填
illness。
42.
句意:他妈妈生气地看着他,因为他打碎了一些贵重的东西。根据“because
he
broke
something
valuable.”可知,妈妈是生气的。angry意为“生气的”,形容词;修饰动词looked需用副词。故填angrily。
43.
句意:——你在这里教书多久了?
——大约两年了。由语境和所给的单词可知,此处选择teach意为“教”;由“For
about
two
years.”可知,此句是现在完成时,空处需用过去分词。故填taught。
44.
句意:他失败了两次,但他仍想再试一次。根据“He
has
failed
twice,”可知,此处需用three的序数词third,指再试一次。故填third。
45.
句意:这位老人除了抽很多烟外,身体状况很好。由“he
smokes
a
lot.”和所给的单词可知,此处选择except意为“除……之外”,是指除了吸烟外,他身体状况很好。故填except。
