【正确答案】：
A
【本题分数】：
1.0分
【答案解析】
根据文章第三段可知蚊子只需要很短的时间就能把血从人身上吸走，美美的饱餐一顿。
[B]与文意不符，根据文章第四段最后一句，一滴血就够繁殖成百上千只蚊子。
[C]与文意不符，文章第四段前三句说感觉痒是因为蚊子的唾液混入了人的血液，它吐出唾液是为了吸血时不让血液凝结。
[D]与文意不符，根据文章第四段第四句可知当人们感觉痒时，蚊子早已离开了。

AMosquitoescanfindenoughfoodinrainyseason.
BRainmakesgrassgrowfast.
CRainprovidesagoodlivingconditionformosquitoes.
DRainprovidesanabundantsupplyofwater.
D
根据文章第五段可知，没有水，蚊子的卵是不能孵化的。
大雨可以提供丰富的水源，也正因为如此，大雨能够产生大量的蚊子。
[A]、[B]文章未提及。
[C]与文意不符，文章第五段第一句只是说雄蚊子和雌蚊子成长早期都是在离水近的地方，并没说大雨可以给蚊子提供好的生存环境。
第3题

AAnnoyed.
BWorried.
CObjective.
DDisappointed.
C
通过文章最后一段的描述，可以判断作者对于蚊子的存在持很客观的态度。
文章指出雄蚊子靠吸食花露生存，它们还可能起到传粉的作用，不论喜欢还是讨厌，蚊子就是存在了。
第4题

第5题

Asheisunfriendly.
Bsheneedsbloodtoproducetheyoung.
Csheisselectiveinfood.
Dshecanlivelongerwithblood.
B
文章第一段明确指出雌蚊子咬人的原因是因为它需要吸血来繁殖后代。
第一段中提出雌蚊子咬人并不是因为它不友好，所以排除[A]。
[C]与文意不符，文章是说雌蚊子在咬人时很善于选择，而不是它在食物方面很善于选择。
[D]文章未提及。

根据文章第一段可知智商低于90的人只能阅读诸如连环画册、报刊标题等蕞简单的读物，而不能对复杂问题做出明确判断。
因此选[B]，排除[A]。
[C]和[D]是第一段最后提到的一些智商高的人遇到的情况，没有上大学，过着平庸的生活。
第7题

DthemassmediaaimsatthemedianI.Q.andthisfactkillsthecreativeintelligenceofpeoplewhoworkinthisfield.
根据文章最后一段可知作者提出大众传媒的兴起是一个复杂的因素，因为大众传媒的目标群体是中等智商的人，这就使得在这个领域里工作的具有高智商创造性思想的人受到了限制。
[A]、[B]和[C]与文意不符。
第8题

AAllofthemgotouniversities.
BMostofthemarefamousperson.
CSomeofthemliveanordinarylifewithahumblejob.
DMostofthemliveanoblelife.
根据文章第一段最后一句话可知，至少近一半具有高智商的人没有被发现，他们没上大学，只有一份平庸的工作，过着这样普通的生活。
[A]与文意不符，他们中有至少一半的人是没上过大学的。
[刚文章未提及。
[D]与文意相反。
第9题

AThelifeofpeoplewithI.Q.'
sbelow90.
BThelifeofpeoplewiththehighestI.Q.
CThereasonwhypeoplehavedifferentI.Q.levels.
DPeoplewithdifferentI.Q.levelsandtheconflictionamongthem.
纵观全文；
文章主要是关于具有不同智商水平的人们的情况，以及他们之间的不和谐的、互相蔑视的关系。
[A]和[B]只是文章写到的一个方面。
[C]文章最后一段提到了一点原因，但这不是文章的主要内容。
第10题
WhatcanweinferfromParagraph2?
APeoplewithhigh-I.Q.willnotlookdownuponthosewithlow-I.Q.
BPeoplewithlow-I.Q.willnotlookdownuponthosewithhigh-I.Q.
CPeopleofdifferentI.Q.group,eitherhighorlow,willscornothers.
DHighbrowswillneverbelookeddownupon.
文章第二段指出有着不同智商的群体产生不合，他们总是互相反对、藐视、瞧不起对方。
高智商的人对看连环画册人的蔑视与中等智商的球员对能吟诗的天才的蔑视是一样的。
[A]、[B]和[D]与文意不符，因为没有哪个智商群体的人不蔑视另外群体的人。
