Tenses that must be mastered in senior high school English? And grammar

Tense is a verb form that expresses behavior, action and state under various time conditions. So when we say tense structure, we mean the verb form corresponding to tense.

English tenses are divided into 16: simple present tense, simple past tense, simple future tense, past future tense, and their continuous tense, perfect tense and perfect continuous tense. This paper focuses on the usage and precautions of the most common tense 1 1.

1.？ General present tense: everyone knows that primary school began to learn this. Emphasize a few points and leave.

a)？ Represents the action, situation, state and characteristics that are happening now. What if? It? Is it? Isn't it? Also? A lot? Trouble? Me? Will it? Like what? Answer? Cup? Yes? Tea.

b)？ Idiom: this should be accumulated by yourself at ordinary times, because there are too many idioms, so there is not much explanation.

Namely:? Do you believe it? It? Or? No,? His? Found it? Had it? Created? Answer? Stir? Are you online? Science? Circle.

Believe in spoken English? It? Or? Not means "believe it or not" and "I'm telling the truth" Do you believe it? It? Or? Not is a fixed sentence, which is equivalent to parenthesis. I believe that the phrase has no morphological changes. Pay attention to this. I will teach you the usage of gerund in the future, and the subject will be involved.

c)？ Regular habitual movements.

Ie: Him? Always? Does it help? Others. ? He always helps others. )

d)？ Objective facts and universal truth. Especially if the context is not the general present tense, it is impossible to keep the tense of the main clause and the clause consistent. ex:？ What? Say? That? That? Sun? Up? Are you online? That? You should pay attention to this sentence. This problem often occurs in attributive clauses in the future. What are the details? Time is talking, but you must first have a concept that objective facts use the simple present tense regardless of the tense of the predicate.

e)？ Express the behavior that will happen according to the regulations, plans or arrangements (limited to some verbs that mean "come, go, move, stop, start, end and continue")? ) can be used with adverbials indicating future time. Common usage is: planes, trains, ships, cars and other means of transportation that run at fixed points on a regular basis.

ex:？ What time? Is it? That? Plan? Leave? Pay attention to this sentence, that's how it is used, and someone will notice the problem: That? A plane? Leaves? Where is it? 3? What time? This? Good afternoon. Why not use the future tense? Yes, it's strange, but that's how it's used.

f)？ In the adverbial clauses of time and conditions, the simple present tense (sometimes the present perfect tense) is often used to indicate future things.

Namely:? What time? What about you? Done? That? Report? Me? Will. Really? Wait? For what? 3? A few hours. (When finished, look down and it will appear.)

2.？ The present continuous tense (be? Doing)? Usage: I have been teaching this since grade one, and now it is easier than usual. It means what you are doing now, but it should be noted that some verbs cannot be used in the continuous tense. Such words are called instantaneous verbs, for example, open,? Borrow, etc. , often encountered in the completion, usually pay attention to accumulation.

3.？ The present perfect tense (is there? Done): important test sites, almost all of them are perfect tense after the second day of junior high school.

a)？ Indicates that the operation has been completed or just completed so far.

ex:？ Me? Really? Just? It's over? Mine? Homework.

b)？ Indicates an action or situation that started from a certain time in the past and continues to the present, and may continue. Progressive verbs are often used at this time. Adverbials of time are often used to indicate a certain point in the past, or a period of time, or the present time. It's the same when you make contact here. You can't use instant verbs, ★★★☆☆☆☆☆.

c)？ Indicates an act or situation that happened in the past but still has an impact on the present. Usually use some verbs, such as: arrive,? Start,? Looking for? Here,? Lose, etc.

Example: John? Really? Is it broken? His? Left? John broke his left leg. )

note:

a)？ The present perfect tense is a link between the past and the present. The difference between the present perfect tense and the past tense is that the present perfect tense emphasizes the dynamic nature of the action, or is influenced by the dynamic nature, which is the dynamic result and has an impact on the present; The past tense only indicates actions that happened at a specific time in the past, and has nothing to do with the present.

Example: why? Working? Are you online? That? Hospital? For what? 8? He used to work in that hospital for eight years. This is just telling a past fact. He is not in the hospital now. )

What? Really? Working? Are you online? That? Hospital? For what? 8? He worked in that hospital for eight years. He used to work and still works in that hospital. )

b)？ Because the completion of adverbial of time containing for plus a period of time or since plus a point of time is dynamic and continuous, terminal verbs or instantaneous verbs cannot be used.

For example: mine? Sister? Really? Have you been there? Married? For what? 5? A few years. (The past participle is used as a predicative to indicate the state, which can be continued)

Mine? Sister? Really? Married. ? No? Excuse me? She ... (terminal verb)

c)？ In "this? Is it? That? First/? Seconds/? Third ...? Time? That sentence pattern requires the use of the perfect form.

Example:? This? Is it? That? Second? Time? That? That? Product? Yes? Our? Company? Really? Have you been there? Display? Are you online? That? International? Exhibition. ? This is the second time that our products have participated in the international exhibition. )

d)？ "Its sentence pattern? Yes/? Really? Both tenses in "been……since" are correct.

Example: It? Yes/? Really? Have you been there? 10? How many years? Since? Me? Finally? Saw? It has been 10 years since I last saw him. )

e)？ In "no? Faster? Compared with ","hardly/? Hardly? ..... when ","before ","before? In sentence patterns such as "to", when the main sentence requires completion.

Example: me? No? Met? That? Professor? prior？ Where to? I have never seen today's professor before. )

4.？ The present perfect continuous tense (yes? Have you been there? Doing): It's very similar to the present continuous tense.

1)? Usage: indicates that an action started at a certain time in the past, continues or appears repeatedly today, or will continue into the future.

For example: we? Really? Have you been there? Work? Open? This? Project? For what? Is it over? Answer? Month? So far, we have been dealing with that project, which took more than a month. )

2)? Note: Compared with the present perfect tense, the present perfect tense emphasizes that the action or state has been continuous or repeated from the past to the present.

5.？ Simple past tense

a)？ Indicates an act or situation that happened at some time in the past.

Example: Me? Went? Where to? Beijing? Finally? Year.

b)？ Used to express past habitual actions. Especially by would/? Used? Where to? The sentence pattern expressed by do itself represents the past tense.

ex:？ Me? Used? Where to? Live broadcast? (pay attention to used? Where to? Use be? Used? Where to? Difference, used? It used to be a table, didn't it? Used? Where to? To is an infinitive symbol, the latter is a preposition, followed by nouns, gerunds and pronouns.

c)？ Sometimes it can replace the simple present tense to express a smooth, polite, polite and negotiating tone.

ex:？ Will it? What about you? Mind? Mine? Sitting? Here? Can I sit here?)

Is it okay? What about you? Pass? Me? That? Pen?

note:

a)？ Pay attention to the collocation of adverbial of time. The adverbial of time in the past tense should be a word or phrase indicating a certain time in the past, such as yesterday. Finally? Month? Are you online? 1999,? Two? How many days? First class. , definitely not together recently, are you? That? Past? 10? Year,? This? Month and so on, because at this time? Adverbials are all related to the present and should be used in the present perfect tense or the general present tense. Note that the second day will be the test center, and you can't escape. You will take the exam almost every time.

b)？ Used? Where to? The negative form and question form of do are very special: you wrote it correctly. Take the negative form as an example: used? Isn't it? Where to? Do what? No? Used? Where to? Do what? No? Use? Where to? Doing the right thing.

6.？ Past perfect tense (had? Complete)

Usage: indicates the action that has occurred or the state that has existed before a certain time or action in the past. It is what we often say: expressing past behavior or state.

Draw a timeline to complete the past _ _ ● _ General past _ ◇ _ General present _ _ _ _ _ _

2)? Note: the logical relationship of "past past" is often embodied through context, not necessarily limited by a certain adverbial of time.

ex:？ There? Had it? Have you been there? Some? One? Are you online? Our? Room? Just? What about now? Because? Me? Notice that? Answer? Burning? Cigarettes End? Open? That? Floor? What time? we? Is it open? That? Front? Doors.

7.？ Past tense and future tense (would/? Should? do)？ It means to see what will happen at some time in the past. In fact, it is no different from the future tense.

ex:？ Me? Say? Open? Thursday? Me? Should? Do you see it? Mine? Friends? That? Next? Day. Customers and direct reports often encounter such examples, so pay attention.

8.？ Past continuous tense (was/? Used to be. Doing)

a)？ Represents an action that occurred at a specific time in the past.

ex:？ Me? Used to be. What are you doing? Mine? Homework? Where is it? This? Time? Yesterday.

b)？ One of the main sentences guided by adverbials of time such as If when and while is the simple past tense, while the other sentence is often the past continuous tense.

ex:？ Me? Used to be. Washing? Mine? Hair? What time? What about you? Knocked? Where is it? That? Front? Doors.

9.？ the simple future tense

a)？ The basic structure is will? /? Should I? Do. Old English thought that will was used in the second and third person, and shall was used in the first person. Later, it was not rigid, and will was more commonly used. Me? Will. Is it? Home? Where is it? 10.

b)？ Some verbs, such as: arrive,? Is it? Is it near? Come on, how about it? Do what? Is it done? Go ahead. Yes,? Leave? Open? Play? Return? Sleep? Start,? Stay and wait. Used in the simple continuous tense, usually used with adverbial of time indicating future time, which can indicate future tense. Contact comparison on the first day? There are many, aren't there? Going? To, the latter includes will/shall, which appeared later. Others, such as sleep, are rare. I have hardly seen sleep used like this in junior high school. Leave? Come on, how about it? Arrivals are also common.

ex:？ Mine? Mom? Is it? Coming? Where to? Visit? Me? Next? A week? And then what? Is it? Stay? Here? Until? May.

c)？ When you say "soon, soon", you can use be? About what? Where to? Do. Emphasize something to be done in the near future or soon. Often used with when. ex:？ Me? Used to be. About what? Where to? Talk? What time? What about you? Interrupted? Me.

D) "Really? Where to? Five usages of "do":

a)？ Arrange something to happen or intend to do something according to the plan.

Example: her? Is it? Where to? Is it? Have you seen it? Are you online? That? The lab? Open? You are sure to see her in the lab on Monday. )

b)？ What to do or not to do (close to should, must, should? Here,? Really? To), a persuasive tone of command.

Example: You? Is it? Where to? Going? Where to? Bed? And then what? Keep? Quiet? Kids. ? Our? Guest? Is it? Have you arrived? Are you online? Less? Than? 5? Son, do you have to? Go to bed and don't make any noise. Our guests will arrive in five minutes. )

c)？ What can or can't happen? May)

Example: How? Me? Me? Where to? Pay? Like this? Answer? Debt? How can I afford such a big debt? )

d)？ It's bound to happen, and it will happen later.

Example: me? Promise? What about you? That? That? Does it matter? _______? As? Soon? As? It's possible. ? Really? Answer? Small? Patience.

A.？ Will. Is it? Participated? B? Will. Is it? Participated? arrive

C.？ Is it? Participated? d？ Is it? Participated? arrive

Will. Is it? Participated? The key point of "to" is that "attend" is an intransitive verb and must be used with "to". In addition, from the context, things are obviously not solved, so we should use the passive voice of the future tense. The answer is B.

a)？ Is it? Where to? Is it? b)？ Is it okay? Is it? c)？ Will. Is it? d)？ Really? Past participle of be

The answer is a)? Is it? Where to? Yes. If we want to avoid food shortage, we must work harder to increase agricultural production.

e)？ What is the sentence pattern that can also mean "coming soon"? Open? That? Point? Yes? Do what.? That? Coach? Is it? Open? That? Point? Yes? Pay? Up? That? Games? Because? Our? Team? Really? Have you been there? Did you score? 7? Points.

note:

Are you online? Use if,? What time? As? Dragon? As? As? Soon? As? After that,? Before? Are you online? Keith? Until,? Unless? Equal conjunctions and adverbs with conjunctions (immediately,? That? In an instant? Adverbial clauses such as direct) generally use the present tense instead of the future tense. Emphasize? Progressive tense or dynamic tense can be used in the perfect tense.

Example: me? Hope? His? Healthy? Will. Really? Improved? By who? That? Time? What about you? Coming? Back? Next? I hope his health will be much better when you come back next year. )

10.？ Future continuous tense (will? Is it? Doing)? Adjust the actions or things that are happening at a specific time in the future.

ex:？ No? Worried? What about you? No? Miss? She ... ? She? Will. Is it? Dressed? Answer? Red? T-shirt And then what? Answer? White? A skirt? Where is it? That? Time.

1 1.？ Future perfect tense (Will? Really? Done)? The act or state of starting at a future time and continuing to another future time, or occurring at a future time, but not for the next? The act or state of having an impact on the future. It's like translating the present perfect tense into the future time period of the timeline. Its usage has changed from being related to the past and present to being related to the future and the future.

ex:？ It? Is it? Report? That? By who? That? End? Yes? This? Century? That? People? Yes? China? Will. Really? Increased? By who? 2? One billion.
