关于时态

babybearmm

经常看到这个版上有同学问时态问题....今天无意中搜到个非常好的时态总结，分享给大家，见附件。
——同学们不要被吓唬住，看上去39页，但我觉得那些图解和例子都非常经典也easy-to-follow，把那些都理解体会，就done了，什么都不用去记忆。

另外分享对我很有帮助的几篇关于verb tense的讨论贴

（Stacey详解一道prep题，后面的Q&A也很有价值，当时看完后我感觉对时态的理解升华了）

最后，the bottom line is - verb tense is a meaning-based issue.

最后的最后，引用Ron大神的话——
** WARNING **
for non-native speakers of english (as well as every other language in the world -- this is not a unique feature of english), verb tenses are MUCH harder than any other aspect of the language.
in fact, it's almost impossible for any non-native speaker of any language to master verb tenses fully and completely.  even when an intelligent speaker has been using his or her second language exclusively for decades, he or she will still routinely make verb-tense errors.

therefore:
DO NOT study verb tense until you have 100% MASTERED the other MAJOR sc topics.
* parallelism
* pronoun use
* subject-verb agreement
* modifier placement
if you cannot identify these error types literally one hundred percent of the time, then do not study other error types -- especially verb tense (which should be the absolute bottom priority for non-native speakers) -- until you can.
