Task 2
还是有点太general, 稍微具体点,加些自己的例子,比如building 什么 gym, public swimming pool, etc这些你说人们时候就能多锻炼,这样比较生动。
Task 3
Proposal paraphrase挺好的
第一个reason引用太多原文的内容了,你直接说 many staffs will deliver the speech during the ceremony which is quite unnecessary and boring.
第二个是reason不是suggestion, 你可以直接说 the reason for the crowed hall is that each student bring as twice guests as before. So if university cut down the maximum number of guest student can bring, this problem will be solved.
Task 4.
概念讲错了
是cultural lag,而不是 transition lag
另外你的例子讲得不够简练 直接说telephone开始只有少数人用,接着说reason 1) no face to face interaction 2) rude (你可以换成别的词,其实所谓paraphrase就是换着词来说同样的意思)这里可以换成什么 inappropriate, not appropriate,
接着再讲一句说后来人们适应了就可以了,甚至觉得 fun and convenient
然后讲概念和例子关系,提一句cultural lag
可以这么说 This is a perfect example of cultural lag, you know, first people dislike it, then with some period of time, they'll adjust it and fall in love with the technology.
