真题一:单项选择(推测用法辨析)
(2024上海浦东期中,沪外版)
-Who is knocking at the door?
-It be Mary.She said she would come at 8 o'clock.
A.must
B.can
C.may
D.need
答案:A
核心知识点:
ust用于肯定推测,意为“一定:肯定”,表示可能性极高(基于逻辑或证据)。
may/might表示“可能”,推测可能性低于must。
解析:根据“she said she would come at8o'clock”可知,敲门人“一定是May”,可能性极高,用
must.
真题二:单项选择(义务与禁止)
(2023江苏苏州期末,沪外版)
You follow the traffic rules when crossing the road.It's dangerous to run.
A.can
B.must
C.may
D.needn't
答案:B
核心知识点:
ust用于表示“必须;义务”,强调强制性。
mustn't表示“禁止;不允许”,语气强烈。
解析:“遵守交通规则”是必须的义务,用must:选项D needn't意为“不必”,与句意不符。

真题三:用所给词的适当形式填空(建议句型)
(2024浙江杭州月考,沪外版)
You(should)eat more vegetables to keep healthy.
(shall)we go to the park this weekend?
答案:1.should2.Shall
核心知识点:
should用于提出建议,意为“应该:应当”,语气委婉。
shall用于第一人称疑问句(Shall I/we..?),表示征求对方意见或提出建议。
解析:第一句建议“多吃蔬菜”,用should:第二句征求“周末去公园”的意见,主语是we,用
Shall。
真题四:句型转换(推测否定与疑问)
(2023安徽合肥期中,沪外版)
按要求改写句子,每空一词。
The man in black coat must be our teacher.(改为否定句)
The man in black coat
our teacher.
一Could she finish the work alone?(作否定推测回答)
-No,she
答案:1.can'tbe2.can't
核心知识点:
must表肯定推测时,否定形式用cant(“不可能”"),不用mustn't(must't表“禁止”)。
could用于推测疑问句时,否定回答用cant(“不可能”)。
解析:第一句否定推测“不可能是老师”,用can'tbe;第二句否定推测“她不可能独自完成”,用
can't。
真题五:短文填空(综合语境运用)
(2024福建厦门期末,沪外版)
阅读短文,用may,must,should,,can的适当形式填空,使短文通顺。
It's 10 p.m.now.My parents(must)be at home because theyusually go to bed early.I(should)call
them to ask,but my phone is dead.The light in their room is on,so they(can't)be asleep.I(may)
go to their room to check.
答案:1.must2.should3.cant4.may
核心知识点:
must表肯定推测(基于日常习惯):should表建议:can't表否定推测(基于事实证据):may表“可
能”(推测可能性较低)。
解析:
1.由“they usually go to bed early'”可知,父母“一定在家”,用must:
2.“打电话询问”是建议,用should:
3.“灯亮着”说明“不可能睡着”,用cant:
