A【文章大意】 本文是一篇说明文,主要介绍了如何健康饮水,以及饮水量应为多少。1.A推理判断题。根据第一段第二句和第三句可知,作者通过摆事实,举例子来证明水对人的身体的重要性,故选A。2.B细节理解题。根据第二段第一句“You may have heard that you should drink eight 8-ounce glasses of water a day.”可知,88原则就是每天要喝64盎司的水,故选B。3.A细节理解题。根据第二段的“The 88 rule essentially overlooks two big sources of daily water consumption. One such source is food.”以及“The other key water source is other beverages.”可知,88原则的缺陷就是忽略了人们从食物和饮料中摄取的水量,故选A。4.B推理判断题。根据最后一段最后两句“If you are looking for concrete advice, though, the best place to look is within. Drink water when youre thirsty.”可推知,作者最后对饮水量多少的建议就是渴了就喝水,故选B。B【文章大意】 本文是一篇议论文,主要讨论了人们对一些食物的错误认识,提倡人们正确认识食物,健康饮食、快乐饮食。5.B细节理解题。根据第二段最后一句“And when we avoid certain foods, we usually compensate by consuming too much of others.”可推知,人们在避免某些食物时,会食用过量其他食物来进行补充,故选B。6.A词义猜测题。根据第四段第四句的转折,并与前文形成对比可推知,实际上普通美国人每天食用三克多一点儿的盐是不过分的,对健康是有利的,由此可推知,画线短语的意思是“合适的”,故选A。7.C推理判断题。根据最后一段倒数第二句“For most people, its entirely possible to eat more healthfully without living in terror or struggling to avoid certain foods together.”和对最后一段的整体理解可推知,作者罗列出人们所恐惧的食物目的是提醒人们这些都是不必要的,只要适量食用,这些食物对身体健康是没有坏处的。毕竟人们总是要吃饭的,吃饭是一种快乐而不是恐惧,故选C。8.D标题概括题。根据第一段的导入,并结合最后一段的点题可推知,本文主要讲述的是人们对食物的一些错误的恐惧认识,作者提倡快乐饮食、健康饮食,故选D。.【文章大意】 本文是一篇记叙文,主要讲述了一家美国中餐厅的发展史。1.their考查代词。此处用形容词性物主代词their修饰名词first Chinese restaurant,在语境中作定语。2.relatives考查名词复数形式。根据语境可知,此处表示人的概念,且没有被冠词修饰,故用复数形式。3.a考查冠词。a total of意为“总共”,符合语境,故用不定冠词a。 4.celebrating考查动词时态。根据语境this year可知,此处用现在进行时,表示现在正在进行的动作或状态,与语境中is呼应。5.for考查介词。固定词组搭配:wait for意为“等待”,符合语境,故用介词for。6.to be考查非谓语动词。want to do sth意为“想要做某事”,符合语境,故用不定式作宾语。7.merely考查副词。副词修饰动词、副词、形容词或者整个句子,在句子中作状语,故用副词merely修饰介词短语in malls。8.reasonable考查形容词。修饰名词的词一般为形容词,故用形容词reasonable修饰名词rent,在句子中作定语。9.developed考查动词时态。与语境中now呼应可知,此处用现在完成时,即:have+done的形式,表示过去发生的事情对现在造成的影响。10.what考查连词。what引导宾语从句,在从句中作宾语,表示物的概念。.Dear Jim,Id like to invite you for dinner in a Chinese restaurant in Los Angeles.
