A)女士年纪越大，她的记忆就越精彩。 B)女士喝的咖啡越多，记忆衰退的速度就越慢。 C)女士年纪越大，记忆衰退的速度就越慢。 D)女士喝的咖啡越多，她的记忆就越精彩。 C首段第2句概括了该段的主要内容，句中的benefit指的是记忆衰退的减缓。因此本段内容
13、为：年龄越长，记忆衰退就比同龄人越慢, 即C。本段关注的是咖啡影响记忆的衰退程度，而非咖啡是否能增加记忆，A.D(记忆力的好坏)在本段并未论及;虽然本段比照了喝三杯或更多咖啡的女性与喝一杯或更少的女性的记忆衰退程度，但这并不意味着咖啡喝得越多越好，因此，B、D中的the more coffee the woman drank这个前提不正确，故两项均错。 2.对于含咖啡因的茶叶的说法，以下哪一项正确? A)影响女士记忆的方式与咖啡一样。 B)影响女士记忆的效果与咖啡一样。 C)促进女士记忆的速度跟咖啡一样。 D)含有的咖啡因与咖啡一样。 A第2段首句中的the same effect与上一段提到
14、的benefit所指一样，故本句说明含咖啡因的茶和咖啡以同样的机制影响女性的记忆衰退程度，选A。第2段首句中although引出的让步状语从句说明咖啡的作用比茶明显。因此B不正确，这样看来，D(茶和咖啡含有同量的咖啡因)也是不正确的;C针对的是增加记忆，而非其衰退程度，不符合文章的论点，也不正确。 3.依据Ritchie所称，患上早老性痴呆病是由于_。 A)脑袋里面缺乏咖啡因 B)淀粉酶的累积 C)脑袋里高水平的蛋白质 D)正常老化当中的不正常代谢 B第4段末句中的beta amyloid.whose accumulation is responsible for Alzheimer”s di
15、sease说明B为此题答案。此题依据Ritchie和Alzheimer”s定位原文后。答案就不难找到。 4.William Scott最有可能同意的是，咖啡因能帮忙_。 A)降低患上早老性痴呆病的风险 B)减缓认知衰退的过程 C)平衡女性荷尔蒙的产生 D)爱护男士和女士不受疾病困扰 B第6段首句开头的The French study confirms previous research说明斯科特认同了法国人的讨论结果，即咖啡因能减缓记忆衰退，因此此题选B。第4段提及咖啡因可以降低导致老年痴呆症的淀粉酶的水平，但要留意的是，该段末也有提及老年痴呆症在正常的老化过程中也会消失，这意味着老年痴呆症也可能与淀粉酶无关，
