小题1:考查时态。根据at the moment“此刻”可知，应该用现在进行时。句子是一般疑问句，应该把are提前。the Greens表示格林一家。故翻译为Are the Greens taking part in/joining in the fashion show。
小题2:考查固定句型。not...until“直到......才......”。故翻译为He didn’t finish his homework until 9 o’clock。
小题3:考查被动语态。被动语态的构成是be动词+过去分词。order“订购”；online/on the Internet“在网上”。故翻译为can be ordered online/on the Internet。
小题4:考查固定句型。It is +形容词（for sb.） to do sth.“做某事对某人来说怎么样”。forgive sb. for doing sth.“原谅某人某事”。故翻译为to forgive the young man for being late again。
小题5:考查固定句型。keep a balance between...“在......之间保持平衡。”故翻译为keep the balance between your / the study and hobby/hobbies。
小题6:考查时态和固定短语。by+过去的时间，用过去完成时。another+数词=数词+more，意为“再多几个”。故翻译为we had set up/built/put up another three/three more museums。
