English multiple choice questions

1. Choose A, and fill in the absolute construction, indicating the condition. Weather permitting, they will visit the park. There is an active relationship between the weather and the permit, so you can only choose a.

2. choose c, past participle as object complement. The relationship between windows and break is passive, and the action has already happened yesterday (not including the infinitive in the future), so choose C.

3. choose B. Check modal verbs. When order is used as the predicate, the object clause is used for the modal verb should, which is similar to a fixed structure.

4. choose C. to investigate the application of absolute construction. The meeting was over, and we all left the room and drove home. Item A constitutes a complete sentence, which is untenable because there is no conjunction between it and the main sentence. Item b represents the future; Subjunctive mood. Only c holds.
