ron关于og 12 125中助动词的用法（已解决）

铁板神猴

Manhattan5th p235:
The first instance of the verb should usually match the helping verb in tense. If you need to change tenses, repeat the whole verb in the new tense.
Wrong: I have never seen an aardvark, but last year my father DID.
Right: I have never seen an aardvark, but last year my father saw one.

Ron的意思说这里manhattan写错了。上面两句都是对的。他说要去提交申请修改MGMAT...
I have never seen an aardvark, but last year my father DID.  ---correct.

anyway, 我还在进一步问他和comparison的总结是否矛盾。等都问清楚了，我把地址贴上来吧~

Ron说我有点想多了 好像的确有点
不过我自己想明白，在GMAT这种考试之中自然讲究comparison中的beauty of parallelism. 两个无所谓是否冲突。记住Ron说的这一点就好了。

in general,
* if you use did/do/does/etc. to stand for an action verb, then it can be parallel to any tense of that action verb.
e.g., you can use "did" in parallel to saw (which is in the same tense), but you can also use it in parallel to has/have seen, will see, sees, etc.

so, for instance,
No one else will ever play that piece as well as you did last night.
--> this sentence is perfectly correct, as is the one about acreage in the OG.

还有Ron说一下这样的句子都是对的！

I have never seen an aardvark, but last year my father saw one.
I have never seen an aardvark, but last year my father did.
I have never seen an aardvark, but next year I may see one.
I have never seen an aardvark, but next year I may.
I have never seen more aardvarks than I saw last year.
I have never seen more aardvarks than I did last year.
