疑难解析
　　1. Are you coming with us? 你和我们一起去吗？
　　这是现在时表示将来动作的用法。英语中类似come，go，fly, arrive, leave, start等表示位置移动的动词的现在进行时态可用来表示按计划安排将要发生的事。如：

www.qihang56.com　　My father is going to Shanghai tomorrow. I’m going to see him off at the station.
　　John is coming here next week and will stay here until May. So he is coming to see us the day after tomorrow.
　　Im seeing her tomorrow. She’s in hospital.
　　What are you doing next Saturday? We’re going to visit a museum.
　　2. Which island shall we go to first？我们先去哪个岛？
　　句中的介词to不可以省略。从语法逻辑看，which island作后面动词的宾语。而go是不及物动词，不能直接跟宾语，只有加上介词to才能与which island构成完整的动宾搭配。类似的还有wait for等。如：
　　–Who are you waiting for？
　　–I’m waiting for you. May I have a talk with you?
　　3. We’ve never been there before.我们以前从未去过那儿。
　　have been to+地点表示“曾经去过某地(现在已回来)。have gone to+地点表示“某人去某地了(现在不在这儿)”。如：
　　(1) —Where have you been? 你去过哪里?
　　　  —I have been to Shanghai. 我去过上海。
　　(2) —Where is she? 她去哪儿了?
　　　　—She has gone to the library. 她去图书馆了。
　　4. We’re all by ourselves.就我们这些人。
　　by oneself 意思是“单独的，独自的”。all修饰by oneself，起加强语气的作用。如：
　　I learned English all by myself. My teacher is the recorder.
　　5. The picnic basket was no longer under the tree.
　　no longer 表示“不再”，与not…any longer同义，强调时间。no more也表示“不再”，与not…any more同义，强调数量。原句还可以说为：The picnic basket wasn’t under the tree any longer. 如：
　　I don’t want wine any more. It’s more than enough.
　　6. Sooner or later you’ll find it somewhere.
　　句中的sooner or later意思是“迟早”，其中and前后的sooner和later为互为反义词。英语中这种短语还有一些，下面几组比较常见：
　　back and white 白纸黑字  every now and then 不时，时时
　　here and there 到处   off and on断断续续
　　days and nights 日日夜夜  more or less或多或少
　　7. As they were very hungry，they ate up all the food soon. 因为他们很饿，所以他们很快就把食物吃光了。
　　1）as引导一个原因状语从句。它与because的区别是：前者表示的原因只是附带说明，无强调客观之意，不能回答why提出的问题；后者着重强调客观原因，用于回答why提出的问题。例如：
　　We all like her as she is kind. She’s kind to everybody.
　　As it was dark, he had to go home. Or his mother would be worried.
　　2）eat up意思是‘吃光”。up与某些动词连用时，表示“完全，彻底”的意思。常见的几个词组有：drink up喝光；use up用完；clean up除掉，把……收拾干净。如：
　　Please eat up your chicken. You need to eat more as a big boy.
　　Drink up your milk before you go to school. It’ll do good to you.
　　8. Children took them back to the boat. 孩子们把它们带回船上。
　　take back为动副词组。在“动词 + 副词”短语中，当人称代词充当它的宾语时，人称代词不能置于副词之后，只能放在动词和副词之间。类似的短语还有look over，wake up，get back，put on等。如：
　　Please wake me up tomorrow morning. I’ll have to get to school half an hour earlier.
