He has gone to the bookshop.汤姆在哪里？ 他到书店去了。3、现在完成时的构成(1)肯定句：现在完成时的肯定句式是“have(has)＋过去分词”。注意：该句式中的have或has是助动词，has用于第三人称单数，其他人称一律用have。(2)否定句：现在完成时的否定句式是“haven't(hasn't)＋过去分词”。(3)疑问句：现在完成时的一般疑问句式是把助动词have或has提到主语之前。回答用“Yes，...have(has)．/No，...haven't(hasn't)．”。现在完成时的肯定句常与副词already，just连用；疑问句和否定句常与ever，yet，never连用；yet常置于句末；already，never，ever，just一般置于助动词have/has之后，过去分词之前4、—Have you seen the robots at the science museum? —Yes. I went there last weekend. 现在完成时表示过去发生或已经完成的某一动作对现在造成的影响和结果,强调的是现在 的情况,所以它不能直接和表示过去某一时间的时间状语连用,如yesterday, last night, three weeks ago, in 2011,等。而一般过去时只表示过去的动作或状态,和现在不发生联系, 强调的是过去的情况,它可以和表示过去某一时间的时间状语连用。例如: I have been to Beijing. 我去过北京。(现在回来了) ——你以前看过这部电影吗? ——看过。我上个月看的。 —　 　 the film before?  —Yes, I 　 　. I 　 　 　 　 last month. 5、Have you lost something important? something, somebody, anything, anyone, nothing等为不定代词,是不指明代替任何特定 名词或形容词的代词。不定代词如有定语修饰,该定语要置于其后。例如:例如：My mom will cook something special for dinner. 妈妈将做些特别的食物作晚饭。 检测案一、单项选择( )1.
