A problem in high school English correction

1. Whether the accompanying adverbial "Compared with the bike" or "Compared with the bike" depends on whether the thing it modifies (that is, the subject of the sentence) is passively modified or actively performs the action. This In the sentence, car is compared, not car is comparing. This car is not advanced enough to actively compare, so I use the form of done

2. The main clause is "The reason for" "this is that", there is an object missing after is, and what follows is an object clause. How to connect the object clause? that.because expresses a reason and can be used as an adverbial clause of reason, but does not express an object clause.

The two verbs are a subordinate clause and a main clause, and do not conflict. If there are really two dos in a sentence, no matter how much that is added, it will be a bad sentence~
