Through the three step judgement method, the answer exercises, can help students will simplify the difficulty problem, the abstraction problem becomes concrete, its grammatical knowledge is numerous, the students want to master the moment, it is difficult to learn, continue to explore the knowledge of grammar skills, through skills, simplified grammar the difficulty is more conducive to learning english.
First, analyze the grammar structure, explore the knowledge points
The verbs that usually change the form of the verbs, there will be a prototype verb prompt. This kind of exercise, we must first understand the purpose of the title, is the investigation of the predicate verb, or the investigation of non - finite verb. When we think, we can judge whether there is a predicate verb in the question. Of course, if there is no predicate verb questions, then fill in the blanks in the study is tense; if the verb appears in the title, to see the property before filling words, in order to determine the effects of temporal, or non predicate verb. If there is a consistency of the two actions before filling in the blank, we can judge that it is to investigate the participle phrase.
Sometimes the problem will be inserted through the grammar, or by way of reverse structure. When we meet the structure of the exercise is more difficult, you can remove excess modification, the grammar into a common model, the exercise will be simplified, so that you can determine the purpose of the test.
?????The day had been looking forward to__?arrive?at last.arrived?he had been looking forward to ???????? the day ?????? ??????????????????????????????????? ??? arriving? Lookforward to? ????????? to ????????????????
Two, according to the time, judge the tense
In grammar, tense can be divided into: the past tense, the present tense, the past progressive tense, the present continuous tense and the present perfect tense. Therefore, in practice, students can read the exercise, find time information, especially looking for time adverbial or verb tenses, etc., according to the time information to determine the temporal grammar.
(I) present perfect tense
??????????????????????????????????????????????????? ???????????? Have you ever been to the imperial palace????????????????????? After that we didn,t meet in.??????????? ? ?????? ????????????????? I,ll take the computer back toyou after use.????????????
??????? ?????? ????????????????? ????? ? ? ? ? ? ? ?? ?ever?for?by now?over along time ??????????????? ??? ??????????????? ???This is the suitable shoes i,vetried.????????????
(two) the simple past tense
The act or state of the past is called the past tense. In practice, concessions and conditions of adverbial clauses, usually the past tense in the future action. There are several symbolic words: last year, then, etc.. Note, however, that there are differences between the present perfect tense and the past tense. The present perfect tense is mainly a representation of the present state, and the past tense is a representation of the past, which is not related to the present state. For example: he lost my textbook, he has lost the key; this grammar representation of his textbook is lost now, but by another method of expression: he lost the key. has become such a language law said his key now found or not found.
(three) now
The present tense refers to the state of being in progress, and the other to represent the repeated action. The main structure is that the subject of the verb ing +be+ (participle), the first person singular verb +am+ ing, the second person singular verb you+are+ ing, the third person singular verb + third person plural verb ing +are+ ing.
(four) the present tense
It mainly refers to the situation or the regular situation, always occurs, the real existence. When there is a time or a conditional clause, the present tense can be used to represent the future. The main structure is as follows: first, the subject + verb singular third person + other (when the subject is the singular of the third person); the other, the subject + verb prototype + the other (when the subject is not the singular of the third person), the second.
(five) past perfect tense
For some of the actions that have occurred in the past. We can measure time. The state of the past time period, in other words, the action that occurred in the past".
Three, the subject predicate relationship, to determine the voice form
In grammar examination, the verb sentence is a common test. The author usually combines passive sentences with verbs. However, when we do it, we can refer to the relationship between the predicate and the subject in order to judge whether it is a passive relationship. Secondly, we can use the time to judge the tense. Be+ is usually a form of past participle. For example: Mike__ (warn) many times not to go wimming alone in the rive before he drowned.warn in front of drown, so in the past time, while warn and Mike are passive, so to use the passive voice. So the space should be filled in had been warned.
In short, through three step principle, the grammatical problems of tense and voice of the master, from accuracy, tense and voice, let the application becomes more accurate; and from learning, mastery of tense and voice, will be able to exercise becomes simplified, thus saving time from the examination of the practice of other subjects; point of view, do in the test to improve the accuracy and to improve performance.
