新GRE阅读考察面很多,主要考察的是学生的逻辑理解能力和推理能力，考生除了拥有大量的词汇以外，还需能够迅速了解出题者的意图。下面给大家准备了一些新GRE阅读的练习。

　　Certain extremely harmful bacteria found only in sewage are difficult to detect directly. Testing for E. coli, an easily detected and less harmful type of bacteria, in ocean water would be a reliable way of determining whether or not these more harmful bac-teria are present, since ocean water contains E. Coli only if the water is contaminated with sewage that contains the harmful bacteria.

　　Which of the following, if true, most seriously weakens the argument?

　　(A) There are many different strains of the E. coli bacteria, and only some of these strains are harmful.

　　(B) Some types of bacteria found in sewage are neither disease-causing nor difficult to detect directly.

　　(C) Some of the types of bacteria found in sewage along with E. coli are not harmful to people unless the bacteria are ingested in large quantities.

　　(D) E. coli dies out much more quickly than some of the more harmful bacteria found in sewage and then can no longer be easily detected.

　　(E) Some of the types of bacteria found in sewage along with E. coli reproduce at a slower rate than E. coli.

　　答案：D
