小题1:考查固定句型。be used to doing sth.“习惯于做某事”。live in“居住在......”。故填My grandparents were not used to living。
小题2:考查固定短语。Be of+抽象名词=形容词，例如“be of use=useful。“对......有价值”be of value to sb.。故填be of great value to。
小题3:考查被动语态。主语是物时，用被动语态，即be+过去分词。故填are often spread by the wind。
小题4:考查固定短语。Lead to“导致”。故填leads to the problem of health。
小题5:考查宾语从句。know后跟宾语从句。主句用的过去时，从句用过去完成时。故填how long he had been abroad。
小题6:考查find的用法。find it+形容词作宾补，不定式是真正的宾语。explain to sb.“向某人解释......”。故填found it hard to explain to me。
