of等修饰。(2)表示“有趣的”，用fun，不用funny，funny意为“好笑的，滑稽的；奇怪的”。单句语法填空Even today I still remember the great fun we had _(play)games on the beach in those happy days.It is great fun _(play)with kids for the

friend.我确信他一定会听你的，因为你是他的好朋友。(2)since在本句中意为“因为”。since既可以用作连词，也可用作副词，其用法及意义如下：表示“由于，因为，既然”，引导原因状语从句，一般置于句首，相当于now that。表示“自从以后，自以来”，可用作连词、介词、副词，用来表示时间，其所在的句子的中心动词用现在完成时。since引导时间状语从句时，若动词为非延续性动词，句子可译为：自以来有多长时间了；若从句的动词为延续性动词时，句子可译为：没做某事有多长时间了。Ill be forty next month，since you ask.既然你问起，我下个月就满40岁了。Since we have no money，we cant buy it.因为没有钱，我们不能买它。My uncle left the town in 1980 and I havent seen him since.我叔叔在1980年离开了这个城镇，我从此以后就没有见过他。Where have you been since I last saw you?自从我上次见到你之后，你去哪了？Its two years since I smoked.我戒烟两年了。Its two years since I began to smoke.自从我开始抽烟有两年了。单词意义区别because引导的从句通常表示说话人认为听话人不知道的原因或理由，从句往往是整个主从复合句的重心。所以在所有表示原因的词中是语气最强的since，assince和as表示原因时，往往表示人们显然已经知道的理由或原因。因此，侧重点是主句的内容，原因只是附带说明，在语气中because最强，since次之(在意义上相当于汉语的“既然”)，as最弱for它表示的原因只是附加说明，所以常用逗号与前一分句分开。另外，for被划归为并列连词，所引导的分句不能放在句首He was annoyed because he missed the bus.他非常生气因为他错过了那班公交车。Since the rain has stopped,lets go for a walk.既然雨已经停了，我们去散步吧。As you object，Ill reconsider the plan.既然你反对，我将重新考虑这个计划。I recommend seeing the latest film，for it is very exciting and interesting.我建议看最新的电影，因为它很有趣又令人兴奋。单句语法填空He has studied very hard _ he came to our school._this method doesnt work，lets try another.sinceSince
