Yours, LiHua 課時作業(yè)(十二) Ⅰ. 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,88原則就是每天要喝64盎司的水,故選B。 3.A　細節(jié)理解題。根據(jù)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??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識,提倡人們正確認識食物,健康飲食、快樂飲食。 5.B　細節(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,吃飯是一種快樂而不是恐懼,故選C。 8.D　標題概括題。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.celebrating　考查動詞時態(tài)。根據(jù)語境this year可知,此處用現(xiàn)在進行時,表示現(xiàn)在正在進行的動作或狀態(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。 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.
