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

いくつかの英文法の間違いボードにいくつかの文章を書いてみましたが、それぞれの

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

文章には何らかの英語の間違いがあります。それは動詞の時制にあるかもしれません。

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

前置詞や語順など、何か他のことに気をつけて文章を通してみてください。

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

文章を見て間違いを探してみる時間、そして間違いを説明します。

okay? Let's get started.

いいですか？始めよう

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

最初のもの："I have met John last year." " I have met John last year.&quot.

There is an error in every one of these sentences.

この文章の一つ一つに誤りがあります。

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

最初の一文で何の間違いかわかりますか？何か心当たりはありますか？考えてみて（明信） そうですか （明信） はい

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

今から訂正します。誤りはこの部分にあります。なぜなら、"last year"と言っているからです。

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

we can't use the present perfect tense.今、私たちが"I have met John last year."と言ったとき。

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

それは現在完了形です。現在完了形では、終了した時間を使うことはできません。

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

だから：終了時間、"last year"のように。quot;last year"のようなものを使うとすぐに、"yesterday"のようになります。

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

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

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

3時間前というのはすでに過去のことで、それは終わった時間です。現在を使うときは

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

完璧な場合、終了した時間のマーカーを使うことはできません。あなたは、"day"のように、未完成の時間を使用することができます。

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

"this week", "this month", and "this year", but you can't use finished time.もしあなたが

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

と言っても過去形に戻って

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

時制、ここでやったように。I'has"を取り出して、次のように書いてあります。

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

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

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

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

Take a second. You have any

ちょっと待ってあなたには

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

エラーがどこにあるか見当がつきますか？間違いはここにあります間違った前置詞です前置詞

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

should be: "She's engaged to a dentist." We actually say " engaged to", "married to".これです。

the problem was with the preposition.

問題は前置詞だった

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

次の1つ："I must to go home now." "I must to go home now.&quot.

What's wrong there?

どうしたの？

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

ここに誤りがあります。誤差は言わずもがなのです。

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

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

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

"must"は、"should"と同じようにモーダルです。

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

"could"、"can"、などなど。You should be saying, "I should go home now.", "I must go home now.".

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

"I could go home now."これらのすべてのモーダルでは、次の動詞を直接使うべきです。

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

と不定詞の形ではありません。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"、などなど。それは間違いだった

here.

ここに

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

次の一枚："She's been in London since 5 months." "She's been in London since 5 months.&quot.

Take a second. What's the mistake there?

ちょっと待ってどこが間違いなんだ？

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

今、私たちは"since 5 months"と言うことができないので、エラーはここで終わっています。私たちは"since"を使用して、プラス

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

何かが起こった時のポイント。もしあなたが時間の長さを与えているのであれば、あるいは

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

period of time, then you have to use the preposition "for".この部分は現在完了形です。

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

のような時間前置詞がよく出てきます。現在完了体を使うと、よく時間前置詞が出てきますが、"since"のように

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

しかし、あなたはそれらを正しく使う方法を学ばなければなりません。

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

Next: "My wife engineer." "My wife engineer.&quot.

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

何がいけないの？それにはいくつかの問題がある

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

まず、すべての英語の文の中で、それは非常に重要なことです。

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

には動詞があり、この文には動詞がありません。英語の動詞は、動詞"to be"にもなります。

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

なぜなら、それは動詞だからですが、何らかの動詞が必要だからです。すべての英文には

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

は動詞なので、ここに動詞を追加する必要があります。 "My wife is..."しかし、今は 'engineer' は単数形しかないので。

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".しかし、それは"a"ではありません。

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

は"e"ここでは、実際には"an"を追加する必要があります。

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

これを正しい文章にするために文法的に考えるべき点がいくつかありますよね？

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

まず、動詞の"is"を追加しなければなりませんでした。次に、不定冠詞を追加しなければなりませんでした。通常は

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

それが何か他のものだった場合は、医師のように、その後、我々はちょうど"a doctor"、"a dentist"と言っていただろう。

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

しかし、単語は"e"で始まるので、私たちは"an engineer"と言う必要があります。
