　　Explanation

　　1.答案:A

　　The error in this sentence occurs at A. The present perfect phrase has not … been in the dependent clause beginning with Although is not consistent with the past tense verb put in the main clause. It should be replaced with the past perfect verb phrase had not … been to indicate how Mrs. Griffin felt previously — i.e. before she put in extra time this year.

　　2.答案:A

　　The error in this sentence occurs at (A), where there is noun-noun disagreement. Instead of the singular A meteorite, the plural Meteorites is needed to agree with the plural nouns found later in the sentence (particles and giants). In addition, the singular verb shows should be changed to show.

　　3.答案：B

　　The error in this sentence occurs at (B), where the plural noun wolves is used incorrectly as the referent of the singular pronoun it. Either the wolf or a wolf should be used instead.

　　4.答案:B

　　The error in this sentence occurs at (B), where there is improper pronoun use. The reflexive pronoun myself is used incorrectly. The first-person singular pronoun I is needed instead so that the sentence communicates clearly that two people got to the box office. (Mitzie...got to the box office and I got to the box office)

　　5.答案:D

　　The error in this sentence occurs at (D), where there is an inappropriate verb form. The infinitive to achieve is needed to parallel the infinitive to use.

　　6.答案:B

　　The error in this sentence occurs at (B), where there is noun-noun disagreement. The singular a member does not agree with the plural trees.

　　7.答案:C

　　The error in this sentence occurs at (C), where a sentence fragment is created. To fix this problem, use have as the main verb of the sentence.
