<1> A.kidneys B.lungs C.bones D.livers

正确答案： B

答案解析：结核病多发于肺部，这是一般的常识。答案选B.

<2> A.with B.without C.of D.out of

正确答案： C

答案解析：die of意思是“死于某种疾病”，其他三个介词都不与die搭配。答案选C.

<3> A.increased B.decreased C.changed D.disappeared

正确答案： A

答案解析：本句后半部说到艾滋病的传播和抗药型结核病的出现，那么根据推理，结核病自然应该增加，而不可能“减少”或“消失”。至于“变化”，不应该是结核病本身发生变化，而应该是发病率发生变化。答案选A.

<4> A.make B.take C.try D.test

正确答案： B

答案解析：从本句的前后句可以推测到本句想说的是“病人每天必须服用几种抗生素药物”，而服药只能选择take，其他几个动词都不合适。答案选B.

<5> A.as if B.as though C.as far as D.as soon as

正确答案： D

答案解析：句首的Bu显然与上句意思发生转折，而四个选项中as if、as though都是“仿佛，宛如”的意思，as far as则是“至于……，就……而言”的意思，填在这里均不合适，只有as soon as （“一……就……”）才恰当。答案选D.

<6> A.refer B.apply C.lead D.amount

正确答案： C

答案解析：本空白处后面有介词to，虽然这几个选项均可与to连用，但意思各不相同：refer to“谈及，参考”；apply to“接洽，适用于”；lead to：“导致”；amount to“合计，总共达……”，只有选择lead才能使本句意思完整、准确。答案选C.

<7> A.effective B.ineffective C.expensive D.inexpensive

正确答案： A

答案解析：只要用心注意上面那句话就可以很容易地找到答案，显然本句想说“现在有一项新的研究想评估这种速效治疗剂究竟效力有多大”。答案选A.

<8> A.cured B.to cure C.being cured D.having been cured

正确答案： A

答案解析：本句考查的是语法。根据所给的动词，我们可以猜到本句想说的是“Joshua Salomon 说，疗程较短的治疗计划可能意味着不仅仅是更多病人被治好”。这里从语法分析，应该是缺一个定语修饰patients.cure是一个及物动词，病人应是被治疗者。B项to cure不能表示被动；C和D虽然有表示被动的意思，但是C是“正在被治疗”，D是“已经被治疗”，二者隐含的时态在这里均不合适，只有A才是恰当的。

<9> A.many B.more C.few D.fewer

正确答案： D

答案解析：前句说到更多病人可以被治愈，根据推理，后句应该是“将感染传递给别人的传染病人就会更少”，因为前后两句实际上具有因果关系。这里必须用比较级fewer，因为few是表示“不多的，几乎没有的”（=not many），而fewer则只是与以前比较“更少”，并没有明确多少。答案选D.

<10> A.provided B.introduced C.tested D.tempted

正确答案： C

答案解析：只有填C项tested （“检验”）才能符合上下文意思，其他三项不仅词义不合适，词的用法也不对。答案选C.

<11> A.bring about B.contributed to C.promote D.prevent

正确答案： D

答案解析：空白处的上一句实际上起到提示作用，两个月的治疗方案可以防止大约20%的新病例，后句自然应是“也可能防止大约20%的结核病死亡”。其他三个选项词义均相反。答案选D.

<12> A.increases B.reductions C.creations D.collections

正确答案： B

答案解析：上面两句说到“可以防止大约20%的新病例和可能防止大约20%的死亡”，这自然是“降低”，绝不可能是“增加”，更不是“创作品”、“收藏品”。答案选B.

<13> A.developed B.invented C.delayed D.refused

正确答案： A

答案解析：空白处的上一句实际上也起到提示作用，可以推测，本句应该是“制订DOTS计划”，而四个选项中只有A项有“制订”的意思，计划也不可能是“发明”，从上下文分析，更不可能是“推迟”或“拒绝”。答案选A.

<14> A.easy B.uneasy C.sure D.unsure

正确答案： C

答案解析：DOTS计划土中就包含“直接观察”的意思，本句中也说到“卫生工作者监督结核病人每天服药”，目的自然是要“确信他们继续治疗”，C项make sure正是“确信”的意思。答案选C.

<15> A.with B.to C.onto D.into

正确答案： D

答案解析：research 后面常用on 或into，偶尔也用for 或after，例如：a research for/after facts （对事实的调查），但不与其他三个选项连用。答案选D.
