some errors in English grammar. I've written some sentences on the board, and each of these

英語語法的一些錯誤。我在黑板上寫了一些句子，而這些句子中的每一個

sentences has some kind of English error. It might be in verb tenses, it might be in

句子有某種英語錯誤。可能是在動詞時態上，可能是在

prepositions, word order, or something else. Go through the sentence, I'll give you a little

介詞，詞序，或者其他的東西。把這句話過一遍，我給你說一下。

time to look at the sentence and try to find the mistake, and then I'll explain the mistake,

時間看句子，並試圖找到錯誤，然後我'將解釋錯誤。

okay? Let's get started.

好嗎？我們開始吧

First one: "I have met John last year." "I have met John last year."

第一個："我去年見過約翰.""我去年見過約翰.&quot。

There is an error in every one of these sentences.

這些句子中，每一句都有錯誤。

Do you know what the error is in the first sentence? Any idea? Think about it. Okay.

你知道第一句話的錯誤在哪裡嗎？知道嗎？想一想吧好吧，我知道了

I'm going to correct it now. The error is in this part. Because we have said "last year",

我'現在就去改正。錯誤就在這部分。因為我們說過"去年"。

we can't use the present perfect tense. Right now, when we said "I have met John last year.",

我們不能'用現在的完全時態。現在，當我們說"我去年見過約翰."。

it's the present perfect tense. With present perfect tense you can't use a finished time.

它'是現在的完全時態。用現在完成時，你不能用完成時。

So: finished time, as in "last year". As soon as you use something like "last year", "yesterday",

所以：完成時間，如"去年"。只要你用"去年"，"昨天"這樣的東西。

"last month", "last summer", and so on; that means you are talking about the past or even

"上個月"，"去年夏天"，等等；也就是說，你說的是過去，甚至是

three hours ago, which is already the past, and that's a finished time. When you use present

三小時前，已經是過去了，那是一個完成的時間'。當你用現在

perfect, you cannot use a finished time marker. You can use an unfinished time, like "today",

完美，你不能使用完成時間標記。你可以使用未完成的時間，比如"今天"。

"this week", "this month", and "this year", but you can't use a finished time. If you

"本週"、"本月"和"今年"，但你不能使用完成時間。如果你

need to mention a finished time in a sentence, then you just go back to use the past simple

需要在句子中提到一個完成的時間，那麼你只需回到使用過去簡單的

tense, as we've done right here. I've taken out the "have", and it says

時態，因為我們'已經做了就在這裡。我把 "have&quot "去掉了，然後它說

"I met John last year." Now, that sentence is grammatically correct.

"我去年遇到了約翰."現在，這句話在文法上是正確的。

Let's look at the next one: "She's engaged with a dentist." "She's engaged with a dentist."

讓我們看看下一個："她和牙醫訂婚了""她和牙醫訂婚了&quot。

Take a second. You have any

等一下你有什麼

idea where the error is? The error is here. It's the wrong preposition. The preposition

知道錯誤在哪裡嗎？錯誤就在這裡。是錯誤的介詞。這個介詞

should be: "She's engaged to a dentist." We actually say "engaged to", "married to". Here,

應該是："She''s engaged to a dentist."我們其實說的是"engaged to"，"married to"。在這裡。

the problem was with the preposition.

問題出在介詞上。

Next one: "I must to go home now." "I must to go home now."

下一篇："我現在必須回家.""我現在必須回家.&quot。

What's wrong there?

有什麼問題嗎？

Here is the error. The error is the fact that we don't need to say,

這就是錯誤。錯誤在於我們不需要說。

"I must to go", but just, "I must go home now." "I must go home now."

"我必須去"，但只是，"我現在必須回家""我現在必須回家&quot。

"Must" is a modal, just like "should",

"Must"是一個模態，就像"should"一樣。

"could", "can", and so on. You should be saying, "I should go home now.", "I must go home now.",

"could"，"can"，等等。你應該說，"我現在應該回家了"，"我現在必須回家了"。

"I could go home now." With all these modals, the verb that follows should be used directly

"我現在可以回家了."對於所有這些修飾語，後面的動詞都應該直接使用。

and not in the infinitive form. We don't need to say "I must to do something." "I must do

而不是用不定式。We don't need to say "I must to do something." "I must do

something", "I must go", "I must study", "I must work", and so on. That was the error

something"，"I must go"，"I must study"，"I must work"，等等。這就是錯誤

here.

在這裡。

Next one: "She's been in London since 5 months." "She's been in London since 5 months."

下一篇："她'自5個月以來一直在倫敦.""她'自5個月以來一直在倫敦.&quot。

Take a second. What's the mistake there?

等一下那裡有什麼錯誤？

Now the error is over here, because we cannot say "since 5 months". We use "since", plus

現在錯誤在這裡，因為我們不能說"自5個月以來"。我們用"自"，加上

the point in time when something happened. If you're giving the length of time, or the

事情發生的時間點。如果你給的時間長度，或者說是

period of time, then you have to use the preposition "for". This part is present perfect, that's

的時期，那麼你就要用介詞"for"。這一部分是現在完成時，that's

fine. Very often with present perfect, we do see time prepositions, like "since" and

細。很多時候用現在的完形詞，我們確實會看到時間介詞，比如"since"和。

"for", but you have to learn how to use them correctly.

"為"，但你必須學會如何正確使用它們。

Next: "My wife engineer." "My wife engineer."

下一篇："我老婆工程師.""我老婆工程師."

What's wrong with that? Well, there're a couple of things wrong with that.

這有什麼不對嗎？嗯，有'有幾件事情不對。

First of all, in every English sentence, it's very important to know that you do need

首先，在每一個英語句子中，都要知道你確實需要

to have a verb, and this sentence has no verb. The verb in English can also be the verb "to be",

要有動詞，而這個句子沒有動詞。英語中的動詞也可以是動詞"to be"。

because that is a verb, but you need some verb. Every English sentence requires

因為那是一個動詞，但你需要一些動詞。每個英語句子都需要

a verb, so we need to add a verb here. "My wife is..." But now, because 'engineer' is only singular,

一個動詞，所以我們需要在這裡加上一個動詞。"我的妻子是......"但是現在，因為'工程師'只是單數。

it's one person, we need to add the indefinite article, "a". But it's not "a" because there

It's one person, we need to add the indefinite article, "a".但它不是"a"，因為有

is an "e" here, so we actually need to add "an". "My wife is an engineer." So there are

是一個"e"在這裡，所以我們實際上需要添加"an"。"我的妻子是一名工程師."所以有

a couple of grammatical points to think about in making this a correct sentence, right?

在使這句話成為一個正確的句子時，有幾個文法點需要考慮，對嗎？

First, we had to add the verb, "is". Next, we had to add an indefinite article. Normally,

首先，我們要加上動詞，"是"。接下來，我們要加上一個不定冠詞。通常情況下，

if it was something else, like a doctor, then we would have just said "a doctor", "a dentist",

如果是別的東西，比如醫生，那我們就會說"醫生"，"牙醫"。

but because the word starts with an "e", we need to say "an engineer".

但因為這個詞的開頭是"e"，所以我們需要說"工程師"。
