2019屆高考英語(yǔ)總復(fù)習(xí)名師全程導(dǎo)學(xué)案：Unit2名師點(diǎn)津1
d. lack of sleep has become the most deadly killer
解析：選b。考查細(xì)節(jié)理解。本文闡述了睡眠與青少年肥胖之間的關(guān)系。第二段說，一項(xiàng)新研究發(fā)現(xiàn)，睡眠太少的小學(xué)生更容易發(fā)胖，美國(guó)有900萬(wàn)6歲以上的孩子患肥胖癥。從文章的敘述判斷選b。
2. the statement “which came first，the chicken or the egg？” suggests that ________.
a. scientists are sure about the causes of children’s obesity
b. it’s easy to decide the cause and effect of this problem
c. scientists are still confused about the cause and effect of the problem
d. you’ll develop obesity if you eat chicken and eggs
解析：選c。考查推理判斷。第三段畫線句子后面又說“換句話說，究竟是發(fā)胖的孩子有睡眠問題，還是睡眠減少導(dǎo)致了體重的增加，這還不清楚。”也就是說，發(fā)胖與睡眠減少這兩者哪個(gè)是原因，哪個(gè)是結(jié)果，科學(xué)家們也還不知道。
3. recent studies show that a child’s weight is influenced by the ________.
a. amount of sleep b. parents’ attitude to him
c. race or gender d. performance in school
解析：選a。考查推理判斷。第三段說，以往的研究表明睡眠不足與發(fā)胖有聯(lián)系，但科學(xué)家不知道哪個(gè)是原因，哪個(gè)是結(jié)果；第五段開頭提到研究的結(jié)論：睡眠似乎是主要因素。也就是說該研究表明，孩子的體重受睡眠時(shí)間長(zhǎng)短的影響。
4. the underlined part in the last paragraph most probably means something ________.
a. acceptable b. understandable
c. reliable d. unreasonable
解析：選d。考查詞義猜測(cè)。后文說“但他們的研究結(jié)論卻很有說服力。”由此可推知，畫線部分的含義應(yīng)該是d；他們本來希望這種說法是錯(cuò)誤的，可是研究結(jié)論卻讓人不得不相信睡眠和肥胖有關(guān)。
b
(XX年黃岡中學(xué)期中測(cè)試)doomed beauties such as cleopata and manilyn monroe were far from alone in their misery. very attractive people tend to form partnerships that are less stable and satisfying than those enjoyed by plain_janes .
according to the research by dr john blaine of the university of southern california, relationships between people whose professions largely depend on their appearance, such as models or actors, tend to end much faster than those between lawyers, doctors and students.
blaine said the beautiful felt different from children. they are treated as special, which may create both arrogance (傲慢)and insecurity. all too often, beauty can be used as an alternative to education. often they are pushed out of their class or town, told to go off and make their fortune in hollywood or london and, when the majority fail, they have few talents to make a living.
