The cookies smell delicious. The soup tastes too salty. The bed feels hard. The idea sounds quite good. All the children look happy. 上面用到的系动词smell，taste，feel，sound，look相当于汉语中的闻起来，尝起来，摸上去，听上去，看起来的概念。要注意这类系动词和系动词be不同，其否定形式和疑问形式的构成要借助动词do。例如：The dishes do not smell very nice.Dose he look worried?The cake dose not taste very good.Module 2 ExperiencesUnit 1 Ive also entered lots of speaking petitions.Language points 1.

I went there last month.我刚去过伦敦，上个月去的。I have already finished my homework. I finished it an hour ago. 我已经完成家庭作业了，一小时前完成的。在没有明确的过去时间状语时，如何判断该用现在完成时还是该用过去时呢？判断的标准是看该行为是否对现在有影响，也就是说该句强调的是什么。试看以下对话：A: Where have you put my book? I cant find it.你把我的书放哪儿去了？我找不到。B: I put it on your desk yesterday. 我昨天放你桌子上了。该对话中，当A 问对方把自己的书放在何处时，A 感兴趣的是现在的状态，因此用现在完成时。但是B 回答时只是说明当时放的位置，所以用一般过去时。再看下面的对话：A: Would you like to go and see the film with me tonight ? 你今晚想和我去看电影吗？B: Sorry, I have seen it already. 不好意思，我已经看过那部电影了。对话中的现在完成时表示对结果的强调：“电影看过了，所以不想再看了。 Module 4 Seeing the doctorUnit 1 I havent done much exercise since I got my puter.Language points1.
