Step 4 Language pints learning
be used fr sth. / ding sth. 意为“被用来做某事”，表示用途或目的，后接名词或动名词，相当于be used t d sth.
be used fr, be used by和be used as的区别是：
be used fr意为“用来做”，后面跟名词、代词或者是v-ing形式，表示目的、用途，相当于be used t d sth。
be used by意为“被使用者”，后面跟使用者。
be used as意为“被当做使用”。
My pleasure也可说成It’s a / my pleasure.或 A pleasure.意思是
“我的荣幸；愿为你效劳；这是件愉快的事”。
mentin表示“提到；提及”，是及物动词，其后接名词或代词作宾语时，无需用任何介词；另外注意不接双宾语。若后接动词，要用动名词，不能用不定式。nt t mentin意为“更不用说；还不算”。口语中说Dn’ t mentin it. 主要用来回答感谢，有时也用来回答道歉。
