　　Part IV Reading Comprehension (Reading in Depth) (25 minutes)

　　Section A

　　Directions: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words on Answer Sheet 2.

　　Questions 47 to 51 are based on the following passage.

　　Scientists say they have high hopes for a drug that could one day provide a new form of treatment for HIV-AIDS. A compound, which interferes with an elusive protein used by the HIV virus to infect human cells, has worked extremely well in monkeys. If the drug proves effective in human trials, scientists say, it could bolster(加強(qiáng))the effectiveness of two existing AIDS drugs, particularly in fighting drug-resistant strains of the virus.

　　Researchers at the pharmaceutical(制藥的)company Merck are very excited about an experimental drug, which has worked as well in monkeys infected with a primate version of the virus as any of the existing anti-AIDS drugs.

　　It works by blocking one of three proteins, or enzymes, the HIV virus uses to gain entrance into and infect human immune system cells.

　　Inhibitor drugs have been developed to block two of the proteins, to slow progression of the disease after infection. They have become standard therapy as a "cocktail" for people infected with HIV.

　　Those enzymes are reverse transcriptase (轉(zhuǎn)錄酶)and protease(蛋白酶). The first converts the virus' genetic material into that of its host cells. The second chops up the resulting larger proteins into smaller pieces, producing smaller viral particles that infect new cells.

　　The third prong of cellular attack is a protein called integrase(整合酶), which experts say has been harder to block. Once HIV fools host cells by changing its genetic information so it can enter them, integrase acts like a cut and paste operation in a word processor, deleting an immune cell's genetic material and replacing it with its own.

　　An integrase inhibitor would give doctors a third line of attack against HIV infection, according to virologist Daria Hazuda of the division of Virus and Cell Biology at Merck.
