The first question means: "Mr. Bush is punctual for everything. What will happen if he is late for the opening ceremony? First of all, rule must, must, that is to say, have a certain foundation. Here, it is hard for the speaker to imagine such an impossible thing (Mr. Bush is late), which is not very certain. We know it means impossible, but it means impossible. Here, it actually means that Mr. Bush is unlikely/almost impossible to be late, so we choose A, can.

The second question, the title should be wrong number. The first word should be theirs, because someone later said that there must be something wrong with theirs, and there are players behind it, which should be players, referring to players. Now let's begin to explain: this sentence means that their team has a good chance of winning. The first sentence says: "Their basketball team has many excellent players", and their basketball team also has many excellent players, "so if nothing unexpected happens", so, apart from what will happen unexpectedly, that is, if there is no accident, "their team won the championship" will win the game. In this way, the need and possibility are ruled out first, because this is a relatively positive speculation and there is no need for possibility; Need is need, which does not conform to the meaning of the sentence. The remaining two words should and would can form subjunctive mood, but this question does not form subjunctive mood. Excluding the application of subjunctive mood structure, should has real meaning, meaning "should" and would mean the future. Because what happened before is an obvious structure, it indicates the future, and accordingly, it should be chosen.

The third question, choose D. Investigate the usage of modal verbs in the meaning of "should, should". Should I reserve a table (seat) a few days in advance? Yes, you must. This hotel is always full, especially at this time. So obviously, this question should be preceded by shall, followed by the affirmative "must" and must be used.

The fourth question has a trap. At first glance, you should use subjunctive mood and choose should have, because it is followed by had ... but it is not the case when you look closely. Although the respondent's words in this question mean "should have left", the speaker is more like expressing that he is already in the process of leaving. He should have gone, but he had an accident on the way. Pay attention to the way in the original sentence! So this is not a subjunctive mood, had is the past tense of had here, and have an accident and had are notional verbs here, not structural auxiliary words, so it does not constitute a subjunctive mood, but an expression of a fact. I'm leaving, which means it's over, because it happened in the past, so it's regarded as the past.

The fifth question is the investigation of antonym interrogative sentences. The front is negative and the back is positive. The first one is would, and the last one is would, so I choose C and would.

The sixth question, this question is really virtual. Things are going very smoothly. What the speaker wants to express is that if he had worked so hard in the past five years, things would not have gone so smoothly. But in fact, it has been very smooth, so the speaker's "if" hypothesis will not happen, just subjective imagination, belonging to the subjunctive mood. Let's look at the structure of subjunctive mood. The last sentence uses would not be, which is the form of the past and the future. Push it back in tense. We should use the perfect when choosing not to work, which means a continuous time (5 years), which means it has been 5 years, so it doesn't need to be explained. Question 7, another subjunctive mood, choose B, because it is followed by had taken, and the subjunctive mood structure is the verb tense structure corresponding to should/would+, so you should use would have been. If you choose would be, it should be followed by have taken.

Question 8, C. subjunctive mood plus inverted structure, according to the last sentence, should have been used in the front, because inverted structure, originally advanced, should not have been used.

Question 9. Virtual inversion. If it is not for snowy weather, if it is not for snowy weather, then according to the tense collocation structure of subjunctive mood, here is the present subjunctive mood. Use the verb would+ and choose A.

Translate! The police announced/stated/implied that most of the victims were shot in the head from behind.

Declare ... declare, explain, announce; Blow is a noun here, which means to hit, hit; It must be a positive speculation about the past; Causing; From behind, from behind.

Be made from behind is not a sentence pattern, nor a structure, and has no usage. Take it apart here, what is made here is passive, which means that the trauma is caused by. . . As a result, from the back are two prepositions, meaning "from the back"
