易混辨析
used to，be used to doing，be used to do
(1)used to do sth.意為“過去常做……”。
(2)be used to (doing)sth.是“習慣于(做)某事”的意思，還可說get/become used to(doing)sth.。
(3)be used to do sth.被用來做某事
①he used to get up early in the morning.
②there used to be a tree in front of the building，usedn’t there/didn’t there?
③you will soon be/get used to living in the country.
④the knife is used to cut bread.
used to，would
(1)used to do 表示過去的特定時期的習慣，暗含現在已不復存在的意思，表示過去與現在的對比。would只表示說話人對過去的一種回想心情，不含有過去和現在的對比。
(2)would之后接表示動作的詞，不接表示認識或狀態的詞，而used to則沒有這個限制。
⑤when my parents were away，my grandmother would take care of me.
⑥mr.white used to live in china，so he is used to chinese dishes.
14.(XX年長沙調研)the country life he was used to ________ greatly since 1992.
a.change b.has changed
c.changing d.have changed
解析：選b。根據句意：“他所習慣的鄉村生活自1992年以來發生了巨大的變化�！笨芍揪涞闹髡Z是the country life，he was used to是定語從句，缺少的是謂語，故選b。
15.every possible means ________ the air pollution，but the sky is still not clear.
a.was used to prevent
b.are used to preventing
c.has been used to prevent
d.have been used to prevent
解析：選c。根據句意：所有可能的方法都已被用來阻止空氣污染，但天空依然不清徹。be used to do sth.意為被用來做某事，排除b，means前有every修飾是單數形式，排除d。再根據后文but the sky is still not clear 可知應該用現在時態，故選c。
