Can you please tell me if the following sentences are correct? Thank you.
Complete the second sentence so that it means the same as the first.
1) He went to bed two hours ago. He has been sleeping for two hours.
2) They have been chatting for one hour. They started chatting one hour ago.
3) His parents moved to Paris n 2009. They have been living in Paris since 2009.
4) He arrived at the cinema two hours ago and is still there. He has been at the cinema for two hours.
5) I have never eaten oysters before. It's the first time I have eaten oysters.
6) She was disappointed with (at/about are possible??) her last exam resuts.
Can you say "We won't start dinner as long as your father arrives"
5) I had never eaten oysters before. This is the first time I have eaten oysters.
6) Either "with" or "about" are fine.
Last question: No. We won't start dinner until your father arrives.
To determine if the sentences are correct, we can check whether the second sentence effectively conveys the same meaning as the first sentence. Let's analyze each sentence:
1) He went to bed two hours ago. He has been sleeping for two hours.
The second sentence correctly conveys the same meaning as the first sentence, indicating that he has been sleeping for the past two hours.
2) They have been chatting for one hour. They started chatting one hour ago.
The second sentence also correctly conveys the same meaning as the first sentence, indicating that they started chatting one hour ago and have been chatting since then.
3) His parents moved to Paris in 2009. They have been living in Paris since 2009.
The second sentence correctly conveys the same meaning as the first sentence, indicating that his parents have been living in Paris since 2009.
4) He arrived at the cinema two hours ago and is still there. He has been at the cinema for two hours.
The second sentence accurately conveys the same meaning as the first sentence, stating that he has been at the cinema for the past two hours.
5) I have never eaten oysters before. It's the first time I have eaten oysters.
The second sentence correctly conveys the same meaning as the first sentence, indicating that it is the first occasion when the person has eaten oysters.
6) She was disappointed with (at/about are possible??) her last exam results.
In this sentence, the word "with" is the most appropriate choice. So, the corrected sentence would be: She was disappointed with her last exam results.
As for your additional question:
Can you say "We won't start dinner as long as your father arrives"?
No, the sentence "We won't start dinner as long as your father arrives" is not grammatically correct. A more accurate version of the sentence would be: "We won't start dinner until your father arrives."
