14.(In)1493

15.B

16.whatwhat解析：這句話的意思是“這就是商家和賣者希望顧客們做的事情”，what引導(dǎo)的是一個表語從句，故答案為what。

17.dailydaily解析：此句意為“但是不要使他們的…工作僅僅成為一長串令人心煩的差使?！憋@然，此空應(yīng)填“每日的，日常的”。

18.andand解析：這三個分詞短語是并列的，故中間的連詞只能用and。

19.differencedifference解析：顯然，這句話是在對老年人和年輕人寫字之間進行比較，而且由后半句中的“getbetterat…”可知，此空必為“不同的”。

20.poorpoor解析：此句意為“但是很容易通過給…表現(xiàn)報酬或創(chuàng)造對報酬太…的期望而扼殺創(chuàng)造性?！憋@然，此空處應(yīng)填“劣拙的，不好的”。

21.losinglosing解析：根據(jù)上下文的意思，很多年輕一代的日本人已經(jīng)不再尊重父母，不再對家庭有責任感，所以這里用losing表示“漸漸失去了”。所以此處應(yīng)填“l(fā)osing”。

22.useuse解析：后面的一句話“Theexpressionis‘both-feet-on-the-ground.”表示down-to-earth的另一種表達方法是both-feet-on-the-ground。而后一種說法是美國人的用法，常常被美國人使用。故答案為use。

23.bringbring解析：通過前一句話“suchadreamerCanbebroughtbacktoearth．”中的brought可以知道，這里應(yīng)該填bring，表示“把…帶到”。故答案為bring。

24.alsoalso解析：由35題解析，拼寫有問題的學生必定握筆習慣不好。

25.ratherrather解析：此空所在句意為“用四個手指握筆而不是三個?！眗atherthan表示“而不是”。

26.C解析：由第二段最后一句“Toreceiveareturnontheirinvestment，wisecorporateexecutiveofficersarerealizingwhatindustrialistsandagriculturistslearnedlongago--efficienttoolsareessentialforincreasedproductivity．”可知。

27.C解析：文中第一段提到“Butsuchbehavioralstudiescannotdistinguishbetweentwocompetingtheoriesofwhysleepisgoodforthememory.”所以他們對為什么睡眠對記憶有好處持有不同的觀點，故應(yīng)選C。

28.D解析
