1.Our maths teacher always tells us _______ make the same mistake again.
A.don’t B.not C.to not D.not to
選D,
詞組tell sb to do sth,否定是tell sb not to do sth,因此選D
2.Doing to much homeworkreally makes the students feel tired.(找出動詞不定式并且寫出它在句子中擔(dān)任的成分)
Doing to much homework,做主語動詞不定式難道不是make嗎？make用在陳述句中不是要把動詞不定式的to省略嗎？動詞不定式不能充當(dāng)謂語哦，（因為動詞不定式和現(xiàn)在分詞，過去分詞同屬于非謂語動詞，故不能充當(dāng)謂語）你能有自己思考很好！
