176. As a result of the ground-breaking work of Barbara McClintock, many scientists now believe that all of the information encoded in 50.000 to 100.000 of the different genes found in a human cell are contained in merely three percent of the cell's DNA. (A) 50,000 to 100,000 of the different genes found in a human cell are contained in merely (B) 50,000 to 100,000 of the human cell's
different genes are contained in a mere (C)
the 50,000 to 100,000 different genes found in human cells are contained in merely (D) 50,000 to 100,000 of human cells' different
genes is contained in merely (E) the 50,000 to 100,000 different genes found
in a human cell is contained in a mere
特指那些genes This question poses two problems: subject-verb agreement and accuracy of expression. Choice E, the best answer, states the matter clearly and grammatically. The subject, all of the information, must be taken as singular because the mass noun information is singular. Choices A, B, and C all mistake the number of the subject and incorrectly use the plural verb are contained. A, B, and D do not make it clear whether 50,000 to 100,000 represents all or a fraction of the genes in a cell. C and D, by referring to cells in the plural, do not make it clear whether the number mentioned is to be found in each individual cell or in a collection of cells. 我的问题是 e中前面加the 和不加意思有什么不一样呢？哪个是指5000-100000是全部的genes，哪个是指只是一部分 如果两个意思不一样的话，选了e难道没有改变原文的意思么？？ |
