The phrase “Marie's tutor recommended that Marie look” contains the present-tense subjunctive verb “look,” and it is right as it is. This is because the subjunctive mood is used after expressions like “recommend that” and “advise that” to express someone's wishes and desires. “Looks,” “looked,” and “will look” are all in the indicative mood, so they are not correct.

This sentence expresses a counterfactual statement, or a statement that does not match the way things are in reality. It is not actually the case that the narrator is the person she is talking to. Counterfactual sentences use subjunctive verbs. So, we need to change the verb “was,” which is in the indicative, to its subjunctive form, “were.”

Here, the words “requests that” introduce a phrase that requires the subjunctive mood. The subjunctive is used after phrases like “requires that” or “requests that” to express the wishes and desires of the person doing the requesting. In this sentence, the verb “stands” is in the indicative mood, but it should be changed to its subjunctive form, “stand.”

Here, the words “requires that” introduce a phrase that requires the subjunctive mood. The subjunctive is used after phrases like “requires that” or “requests that” to express the wishes and desires of the person doing the requesting. In this sentence, the verb “studies” is in the indicative mood, but it should be changed to its subjunctive form, “study.”

This sentence uses the subjunctive verb “be” in the phrase “he be committed”; however, in the way the sentence is written, this phrase was spoken by Bob's mother, who believes it to be true. It's not part of a phrase that expresses any kind of wish, desire, or counterfactual statement. To Bob's mother, the idea that Bob is committed to studying for two hours is a true fact about the world. Therefore, this fact should be expressed using the indicative mood, not the subjunctive. We should change the subjunctive verb “be” to its indicative form, “is.”

The second part of this sentence expresses a counterfactual statement. It is describing what might have happened if the weather had been nice; however, we know that in reality, it was raining. Since counterfactual statements use the subjunctive mood, we need to change the indicative verb “go” to a past-tense subjunctive form, “would have gone.” We know that the subjunctive form has to be in the past tense because the conditional is talking about what might have happened in the past.

This sentence is an example of the present subjunctive, which is most commonly used in English to express hypothetical situations, wishes, and desires. The correct long form of the sentence is “if you were to choose that restaurant,” and “were you to choose that restaurant” is simply an inversion and shortening of the long form. (“Were you to have chosen that restaurant” is the past subjunctive, which doesn’t match the future conditional form of the second half of the sentence.)

The subjunctive verb mood is used when sentences express conditions contrary to fact, or as in this case, in clauses that contain an order or a recommendation. The correct version of this sentence reads: "It is necessary that Danielle know what time she is being picked up."

The word "if" at the beginning of the sentence indicates that the sentence is an indicator that the sentence is in the subjunctive mood. Given that the sentence is subjunctive, the word "was" should be replaced by "were."

The first part of the sentence indicates that the sentence is a wish, therefore, the sentence is in subjunctive mood. "Were" is the correct verb to use with "school" when using the subjunctive mood.
