　　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. bore 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 rerent 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 rlexive 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.
