Now I take a taxi. She used to be very shy. “be used to doing”表示习惯于干某事 be used for意为“（某物）被用做”其后接名词、代词或动名词。如：（1）This kind of bamboo can be used for water pipes . 这种竹子可用作水管。（2）A knife can be used for cutting bread . 刀可用来切面包。be used to do sth. 也可表示“（某物）被用做”，但其后接动词原形。如：（3）A hammer is used to drive nails . 锤子是用来敲钉子的。提示：be used as相当于be used for的用法。如：（4）The girl is being used as a servant in the house . 这个女孩在家里被当做佣人使唤着。典型例题解析：1.老人们被照顾地很好。The old _ _ after well.解析： 这个题主要考查被动语态的结构be + 动词的过去分词和应用，在本题中应该是be looked after.2.You can use the box _ the toys.A. carry B. carrying C. to carry D. carried解析：在这个题目考查一个短语的应用 use sth to do利用某物做某事，因此答案为C。中考连接：( ) 1.Although Tom failed the game, _ he said he would try again.A.
