21. c. 時(shí)區(qū)time zone, 是固定詞組。
22. d. 人們習(xí)以為常了，所以很少想到它，選rarely, 經(jīng)常想起、從不想起和只想起它都不合理。
23. b. 句意應(yīng)為每個(gè)地區(qū)都確立自己的時(shí)間，只有establish可以表示建立制度。
24. a.根據(jù)上下文可判斷出此處為轉(zhuǎn)折對(duì)比關(guān)系， 而by contrast 表示相反的對(duì)比，所以選however。
25. c. 根據(jù)“太陽(yáng)時(shí)”，只要離開(kāi)幾英里，表就會(huì)有一些不準(zhǔn)，而不是不同、錯(cuò)誤或誤解。
26. d. 需要出現(xiàn)應(yīng)該搭配的動(dòng)詞是arise。
27. a. 是需要調(diào)整時(shí)間，而不是使時(shí)間有組織、改變或標(biāo)準(zhǔn)化。
28. d. 根據(jù)上下文，是在美國(guó)境內(nèi)有300多個(gè)地區(qū)時(shí)。
29. a. 根據(jù)文意，火車(chē)不可能在每個(gè)地方都準(zhǔn)時(shí)，所以選everywhere, 和impossible 構(gòu)成部分否定。
30. d.該系統(tǒng)被證明很幫助，應(yīng)該用prove的主動(dòng)形式，時(shí)態(tài)用一般過(guò)去時(shí)。
