Usually, mistakes are not serious (真剣). If you forget (忘れる) “a” or “the” people will be able to understand you, or if you say “Go to shopping” instead of (変わりに) “go shopping” (買い物は場所ではないから”to”は使えない), people will still understand your meaning. But some mistakes can be very dangerous.
This series is about the most dangerous mistakes in English. These are mistakes that could cause a serious misunderstanding (重大な誤解の原因になる). Here’s number 5:
Even really high-level student (上級の生徒）make mistakes with "by" and "until." Sometimes, it can really change the meaning (意味が全然変わる場合もある).
例：
I'll be home by 6:00. (６時までに家に帰ります。）
I'll be home until 6:00. (６時まで家にいます。）
Just remember that "until" is 「まで」 and "by" is 「までに」.
Here are some sentences using "until" and "by." Can you write them in English?
1. ９時まで働かなければなりません。
2. あなたは試験結果を３月１日までに受けとります。
3. 彼はあしたまでに決めます。

Nice job. You got 10/12 right!
When No.7 is a positive sentence, can I say "I will be able to start by Saturday."? I memorized wrongly I cannot use ‘start’ and ‘until’ together. You gave a good chance to review grammar.
Sorry, I didn't see your comment before. Yes, it's fine to say "I will be able to start by Saturday."
