22、 A 【文章大意】 本文是一篇說明文,主要介紹了如何健康飲水,以及飲水量應(yīng)為多少。 1.A　推理判斷題。根據(jù)第一段第二句和第三句可知,作者通過擺事實,舉例子來證明水對人的身體的重要性,故選A。 2.B　細(xì)節(jié)理解題。根據(jù)第二段第一句“You may have heard that you should drink eight 8-ounce glasses of water a day.”可知,8×8原則就是每天要喝64盎司的水,故選B。 3.A　細(xì)節(jié)理解題。根據(jù)第二段的“The ‘8×8’ rule esse

23、ntially 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,8×8原則的缺陷就是忽略了人們從食物和飲料中攝取的水量,故選A。 4.B　推理判斷題。根據(jù)最后一段最后兩句“If you are looking for concrete advice, though, the best place to look is within. Drink water when you

24、049011;re thirsty.”可推知,作者最后對飲水量多少的建議就是渴了就喝水,故選B。 B 【文章大意】 本文是一篇議論文,主要討論了人們對一些食物的錯誤認(rèn)識,提倡人們正確認(rèn)識食物,健康飲食、快樂飲食。 5.B　細(xì)節(jié)理解題。根據(jù)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,人們在避免某些食物時,會食用過量其他食物來進(jìn)行補充,故選B。 6.A　詞義猜測題。根據(jù)第四段第四句的轉(zhuǎn)折,并與前文形成對比可推知,實際上普通美國人每天食用

25、三克多一點兒的鹽是不過分的,對健康是有利的,由此可推知,畫線短語的意思是“合適的”,故選A。 7.C　推理判斷題。根據(jù)最后一段倒數(shù)第二句“For most people, it􀆳s entirely possible to eat more healthfully without living in terror or struggling to avoid certain foods together.”和對最后一段的整體理解可推知,作者羅列出人們所恐懼的食物目的是提醒人們這些都是不必要的,只要適量食用,這些食物對身體健康是沒有壞處的。畢竟人們總是要吃飯的,吃飯是一種快樂

26、而不是恐懼,故選C。 8.D　標(biāo)題概括題。根據(jù)第一段的導(dǎo)入,并結(jié)合最后一段的點題可推知,本文主要講述的是人們對食物的一些錯誤的恐懼認(rèn)識,作者提倡快樂飲食、健康飲食,故選D。 Ⅱ.【文章大意】 本文是一篇記敘文,主要講述了一家美國中餐廳的發(fā)展史。 1.their　考查代詞。此處用形容詞性物主代詞their修飾名詞first Chinese restaurant,在語境中作定語。 2.relatives　考查名詞復(fù)數(shù)形式。根據(jù)語境可知,此處表示人的概念,且沒有被冠詞修飾,故用復(fù)數(shù)形式。 3.a　考查冠詞。a total of意為“總共”,符合語境,故用不定冠詞a。 4.celebra

27、ting　考查動詞時態(tài)。根據(jù)語境this year可知,此處用現(xiàn)在進(jìn)行時,表示現(xiàn)在正在進(jìn)行的動作或狀態(tài),與語境中is呼應(yīng)。 5.for　考查介詞。固定詞組搭配:wait for意為“等待”,符合語境,故用介詞for。 6.to be　考查非謂語動詞。want to do sth意為“想要做某事”,符合語境,故用不定式作賓語。 7.merely　考查副詞。副詞修飾動詞、副詞、形容詞或者整個句子,在句子中作狀語,故用副詞merely修飾介詞短語in malls。 8.reasonable　考查形容詞。修飾名詞的詞一般為形容詞,故用形容詞reasonable修飾名詞rent,在句子中作定語。

28、 9.developed　考查動詞時態(tài)。與語境中now呼應(yīng)可知,此處用現(xiàn)在完成時,即:have+done的形式,表示過去發(fā)生的事情對現(xiàn)在造成的影響。 10.what　考查連詞。what引導(dǎo)賓語從句,在從句中作賓語,表示物的概念。 Ⅲ.Dear Jim, I􀆳d like to invite you for dinner in a Chinese restaurant in Los Angeles. I can imagine how surprising you ┬to
