Skyhigh 3 Unit 9 - Wish

Explanation
The correct answer is "could" because it is used to express an ability or possibility in the past or present. In this sentence, the speaker is expressing a desire or a hypothetical situation of being able to play the piano.

Explanation
The correct answer is "would". In this sentence, the speaker is expressing a desire or a polite request for the neighbors to keep the noise down. "Would" is used to talk about hypothetical or imagined situations, and in this case, it suggests that the speaker wants the neighbors to imagine or consider keeping the noise down. "Could" would also be grammatically correct in this sentence, but it would imply a different meaning - the speaker would be asking if the neighbors have the ability to keep the noise down.

Explanation
In this sentence, the speaker is expressing a hypothetical or unreal situation. The use of "wish" indicates that the speaker wants something to be different from reality. In this case, both "was" and "were" can be used interchangeably to convey the unreal or hypothetical meaning. The choice between "was" and "were" depends on the subject of the sentence. If the subject is "I" or a singular noun, "was" should be used. If the subject is "he," "she," "it," or a plural noun, "were" should be used.

Explanation
The correct answer is "had". This is because the sentence is expressing a hypothetical or unreal situation in the past. The use of "wish" indicates that the speaker wants something that is not true or possible. Therefore, "had" is the correct past tense form of the verb "have" to complete the sentence.

Explanation
The correct answer is "to see" because the phrase "I wish" is followed by a verb in the infinitive form. In this case, the verb is "to see" which indicates the action that the speaker wishes to happen.

Explanation
The correct answer is "could help". This is because the sentence is expressing a hypothetical situation in the present. The speaker is saying that they would like to help, but they are too busy to do so. The use of "could help" implies that if they were not busy, they would be able to help.

Explanation
The correct answer is "you" because the phrase "I wish you all the best" is a common expression used to express good wishes or good luck to someone. The pronoun "you" is the correct choice here as it refers to the person to whom the speaker is addressing their wishes.

Explanation
The correct answer is "would". In this sentence, the speaker is expressing a hypothetical or unreal situation. The use of "would" indicates a desire or preference for the situation to be different from reality.

Explanation
In this sentence, the use of "could" is correct. The sentence is expressing a past unrealized possibility. The subject of the sentence is unable to come skiing with them because he hasn't recovered from the operation. The word "could" indicates that he had the ability or possibility to come skiing with them, but it didn't happen due to his condition. "Would" would not be appropriate in this context because it implies a future unrealized possibility or a conditional statement.

Explanation
The word "wish" can function as both a verb and a noun. As a verb, it refers to expressing a desire or hope for something. As a noun, it refers to a desire or longing for something. Therefore, the correct answer is "Both" as "wish" can be used as both a verb and a noun.

Explanation
The word 'wish' is not a modal verb. Modal verbs include words like 'can', 'could', 'may', 'might', 'shall', 'should', 'will', 'would', 'must', 'ought to'. While 'wish' expresses a desire or hope, it does not have the same grammatical characteristics as modal verbs.

Explanation
The word "wish" expresses a strong desire or longing for something that is not currently true or possible. "If only" is a phrase that is often used to express a strong wish or desire for something to be different or for a specific outcome to occur. Therefore, "If only" is a suitable replacement for "wish" in this context.

Explanation
In this sentence, the verb "wish" is used to express a hypothetical or unreal situation. According to the traditional rule, "was" is used with singular subjects (e.g., I, he, she, it) and "were" is used with plural subjects (e.g., we, you, they). However, in modern usage, "were" is often used with singular subjects in these hypothetical or unreal situations. Therefore, both "was" and "were" can be used in this sentence, making the answer "Either could be used here."
