OG说target at（而不是target to) 更 idiomatic form，那咱就信



下面的话是从beatgmat论坛抄的

Hmm, let's see. The gun is targeted at you. That's a good target to choose. Those are both okay.

In general, I'd guess that "target at" should be followed by a noun ("at" is a preposition) and "target to" should be followed by the infinitive form of a verb ("to choose"). I don't know whether those would be universal rules or just "often but not always." (Though, in English grammar, it seems there's an exception to just about everything if you look long enough!)

Verb
A verb is a word expressing an action or a condition of a subject.

There are three properties which characterize verbs in English--tense, voice, and mood.

In English the fourteen verb tenses express the time or relative time in which an action or condition occurs.

The voice of a verb, passive or active, expresses whether the action is being received by the subject or being done by the subject. The two voices may occur in any tense.

The mood of a verb expresses the conditions under which an action or condition is taking place. In English there are three moods--indicative, subjunctive, or imperative. Indicative and subjunctive can be in any tense; imperative, only in the present tense.

Verbs are also classified according to function. Action verbs show action or possession. Action verbs are either transitive or intransitive. Linking verbs show the condition of the subject. Auxiliary verbs, also called helping verbs, are used with other verbs to change the tense, voice, or condition of the verb.

Conditional verbs are verbs conjugated with could, would, or should to show a possible condition. They may be in any tense.

The principal parts of a verb are the four forms of the verb from which all forms of the verb can be made. In English the four principal parts are the present (or infinitive), the past tense, the past participle, and the present participle. Since the present participle is always formed the same way (add -ing), some lists of principal parts omit it.

For more on most of these forms, see the specific entries in the glossary.

og的人狡猾啊
verb form说明里就是不写 一般过去时

结果就错这上了


不过这样的话，一般过去时  和   现在完成时 怎么区分啊
有have或has的present perfect，也可以表示 continues in to th present啊

Tense of Verbs
The word tense comes from the Latin word, tempus, which means "time." The tense of a verb shows the time when an action or condition occurred. In English the tense also may provide emphasis and may determine whether or not an action or condition was continuous or repetitive.

There are fourteen tenses in modern English.

There are three basic tenses: past, present, and future. They show whether a simple action or condition occurred, occurs, or will occur in the past, present, or future.

There are three perfect tenses: past perfect, present perfect, and future perfect. They show whether an action or condition had occurred relative to the past, has occurred relative to the present, or will have occurred relative to the future.

There are six progressive tenses: past progressive, present progressive, future progressive, past perfect progressive, present perfect progressive, and future perfect progressive. They show a continuous action or condition that was occurring in the past, is occurring in the present, will be occurring in the future, had been occurring relative to the past, has been occurring relative to the present, or will have been occurring relative to the future.

There are two emphatic tenses: past emphatic and present emphatic. They provide emphasis especially in questions and negatives for actions or conditions that did occur in the past or that do occur in the present.

ing 和 ed也能平行？
og说，能。
你不能，我让你能。

扯远了。东拉西扯那个词怎么说来着，忘了，用distract凑数了

首先，participles x-ed and y-ing in a correct parallel construction
其次，为什么不是ed和ed平行哪。
因为还要考虑到verb的含义，ed的是过去发生的，ing的是随后持续地状态

即所谓考点的 verb form


参见og SC 42

为了找that of的用法，引出来这么一大片

Problems with Comparatives


关于that of的
You usually use "that of" or "those of" instead of repeating a noun to express a logical comparative.

e.g

Incorrect: A car in India is much different from USA
Correct: A car in India is much different from that of USA

Incorrect: The question whether to divest themselves of stock in companies that do business in South Africa is particularly troublesome for the nations 16 private Black colleges because their economic bases are often more fragile than most predominantly White colleges.

Correct: The question whether to divest themselves of stock in companies that do business in South Africa is particularly troublesome for the naiton’s 16 private Black colleges because their economic bases are often more fragile than those of most predominantly White colleges.

You’re comparing between economic bases of Black colleges and economic bases of White colleges.

clause里面
relative pronoun就是对refer的词的补充说明

但是用 ,and... 来做clause的话
就会引起undue emphasis ，过度强调

-- relative pronoun 和 and 在引导 claise上的不同
