网友回答
(答案→)Mom often tells me neither to show myself off nor to look down on/upon others.
解析：
【小题1】考查固定句型和固定短语。tell sb. to do sth.“告诉某人做某事”；neither...nor...“既不......也不......”；show off“炫耀”；look down on sb.“轻视某人”。故翻译为Mom often tells me neither to show myself off nor to look down on/upon others.
【小题2】考查固定句型。so/such...that...“如此......以至于......”，that后跟一个句子；so后加形容词或副词；such后加名词；in a hurry to do sth.“匆忙去做某事”，是固定短语；故用such修饰hurry。forget to do sth.“忘记要做某事”。故翻译为He was in such a hurry to go to work that he forgot to turn off the radio.
【小题3】考查固定句型和worth的用法。be sure“确定”，后跟宾语从句，if/whether“是否”；be worth doing “值得做某事”；reply to“回信，回复”。故翻译为I’m not sure if/whether his letters are worth replying to.。
【小题4】考查现在完成时。have gone to“去了某地，不在说话的地方”；have been to“去过某地”；have been in“在某地多久了”。故翻译为Has Mr Brown gone to Shanghai? Yes, he has been there for three months.。
【小题5】考查固定句型和固定短语。Something is wrong with...“某物出毛病了”；have sth. done“让某事被别人做”。故翻译为Something is wrong with your car and you must have it repaired as soon as possible.。
