1. The man has two dogs. One is a small black and white dog, and the other is a big brown dog.

2. The man has two dogs. One is small black and white, and the other is big brown.

(Are the expressions grammatical?)

3. If school finishes early, I will go to an academy.

4. If school finishes early, I will go to a video arcade to play video games.

5. If school finishes early, I will go to see a concert with my close friends.

6. If school finishes early, I will watch a soap opera at home.

7. If school finishes early, I will have to go back home to help mother clean the house.

8. If school finishes early, I will have a meeting with my friends to do something interesting.

(Would you check the sentences? Are they all grammatical? Thank you for your help....and have a great weekend.)

#1 is FAR preferable to #2, which is not phrased correctly.

The rest are fine.

Here's a rephrasing of #2, in case you want to use it:

The man has two dogs. One is small with black and white coloring, and the other is big and brown.

1. The expressions in both Sentences 1 and 2 are grammatical, but Sentence 2 is more concise. Both sentences convey the same information about the two dogs.

2. Sentences 3-8 are all grammatical and can be used to describe different potential activities or scenarios if school finishes early. Each sentence follows a similar structure where "If school finishes early" is the conditional clause and the following statement describes what the speaker intends to do in that situation.

Hope that helps! Have a great weekend too!
