分析 本文主要講述了 HIV 病毒對人體的影響,以及科學(xué)家的一定的研究成果.
解答 59.C 細(xì)節(jié)題.根據(jù)文章內(nèi)容,HIV has several ways of escaping the immune response.Unlike most viruses,HIV specifically attacks a type of white blood cell that is critical to our immune system由此可知,HIV病毒尤其會攻擊對人體免疫系統(tǒng)非常重要的白細(xì)胞來逃避免疫反應(yīng).結(jié)合選項,故選C
60.C 詞義猜測.根據(jù)文章內(nèi)容,During reproduction,the HIV virus also picks up many new mutations (變異),which often change it enough that any antibodies produced earlier during the infection no longer recognize it.在細(xì)胞繁殖過程中,HIV 病毒會產(chǎn)生很多新的變異.而這些變異經(jīng)常會使 HIV 病毒發(fā)生足夠大的變化而任何抗體都不能將其抑制.結(jié)合選項,C符合文意
61.D 細(xì)節(jié)題.根據(jù)文章內(nèi)容,After performing test-tube studies showing the effectiveness of the antibody,the researchers evaluated its safety in humans in a small trial.在進(jìn)行試管研究表明抗體的有效性之后,研究人員也更多的關(guān)注該抗體的安全性,結(jié)合選項,故選D
62.B 推理題.根據(jù)文章內(nèi)容,Overall,this investigation shows the safety of injections of antibody 10-1074in humans.Thus,researchers may be able to build a cocktail of antibodies that effectively block active HIV infections.綜合考慮,調(diào)查研究顯示適量的抗體注射對人體是安全的,因此,研究人員也許能夠發(fā)明一種雞尾酒抗體來有效的抑制 HIV 病毒的感染.結(jié)合選項,故選B
點評 本文是一個科教類閱讀,題目涉及多道細(xì)節(jié)理解題,做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進(jìn)行仔細(xì)分析,結(jié)合選項選出正確答案.推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據(jù).
