-Phrasal verbs - Phrasal verbs in English can cause difficulties for many learners because they have several meanings and different syntactic patterns.There are also a number of phrasal verb differences between American and British English.
Word derivation - Word derivation in English requires a lot of rote learning.For example,an adjective can be negated by using the prefix un- (e.g.unable),in- (e.g.inappropriate),dis- (e.g.dishonest),or a- (e.g.amoral),or through the use of one of a myriad of related but rarer prefixes,all modified versions of the first four.
Size of lexicon - The history of English has resulted in a very large vocabulary,essentially one stream from Old English and one from the Norman infusion of Latin-derived terms.(Schmitt & Marsden claim that English has one of the largest vocabularies of any known language.) This inevitably requires more work for a learner to master the language.

选A
解答这道题目必须注意的问题是,前后两个分句之间的主谓一致问题.
首先注意两个分句的主语.逗号后面主语是the meaning,而逗号前,大体扫一下选项,可以判断要填的主语是you.
那么,既然判断出两个分句主语不一致,b和c两个选项不可以选.这两项意味着逗号前分句的主语也是the meaning.
这个句子是一个有when引导的条件状语从句.主句用的一般将来时,从句,即逗号前的句子,用一般现在时.
这句话的意思是,当你读第二编的时候,文章的意思就更加清楚了.
