真题演练(一) [2017]
解析 考查介词。此处指作为抵抗心脏病的一种方法，所以用介词as。
解析 考查名词复数。side effect副作用，由前面的sme和下文中的两个例子“verweight and heart disease”可知名词effect用复数形式effects。
Fat and salt are very imprtant parts f a diet.They are required 63. (prcess) the fd that we eat，t recver frm injury and fr several ther bdily functins.When fat and salt 64._______________ (remve) frm fd，the fd tastes as if it is missing smething.As 65.__result，peple will eat mre fd t try t make up fr that smething missing.Even 66. (bad)，the amunt f fast fd that peple eat ges up.Fast fd 67. (be) full f fat and salt；by 68. (eat) mre fast fd peple will get mre salt and fat than they need in their diet.
解析 考查非谓语动词之动词不定式。require sth.t d sth.需要某物做某事，此处用了其被动语态形式，所以填动词不定式t prcess作主语补足语。
解析 考查动词的时态和语态及主谓一致。根据语境可知此处用一般现在时，由于主语fat and salt是复数概念，且与remve是被动关系，所以填一般现在时的被动语态结构are remved。
解析 考查固定搭配中的冠词。as a result结果，是固定搭配。
解析 考查副词的比较级。根据语境可知，此处表示程度的加深，所以用比较级形式。even wrse更糟的是，可以看作固定搭配。
解析 考查动词的时态和主谓一致。根据行文的时态可知，此处用一般现在时；句子的主语fast fd(快餐)是不可数名词短语，故填be的第三人称单数形式is。
解析 考查非谓语动词之动名词。表示方式的介词by之后接动名词作宾语。
Having enugh fat and salt in yur meals will reduce the urge t snack(吃点心) between meals and will imprve the taste f yur fd.Hwever，be 69. (care) nt t g t extremes.Like anything，it is pssible t have t much f bth，70. is nt gd fr the health.语篇解读 本文是一篇说明文。文章分析了饮食低脂、低盐的利弊以及对人体健康的影响。
解析 考查词性转换之名词变为形容词。be之后接形容词作表语，care的形容词形式是careful。
解析 考查非限制性定语从句的引导词。分析句子结构可知，空格处所填词引导非限制性定语从句并在从句中作主语，且指代整个主句的内容，故填关系代词which。

(lay) the track and then building a strng rf ver 64. tp.When all thse had been dne，the rad surface was replaced.
解析 考查名词复数。crwd是可数名词，且前面没有限定词，故应用复数形式。
解析 考查介词。travel t and frm wrk上下班。
解析 考查非谓语动词。included后的dig，lay和build是三个并列的动作，根据digging及building可知，lay也应用动名词形式。
解析 考查冠词。此处特指“地铁的顶部”，故用定冠词the。
Steam engines 65. (use) t pull the carriages and it must have been 66. (fair) unpleasant fr the passengers，with all the smke and nise.Hwever，the railway quickly prved t be a great success and within six mnths，mre than 25,000 peple were using 67. every day.
解析 考查时态、语态和主谓一致。steam engines为复数名词，与use是被动关系，且动作发生在过去，故用一般过去时的被动语态，即填were used。
解析 考查词性转换之形容词变为副词。所填词修饰形容词unpleasant，故用fair的副词形式fairly。
解析 考查代词。use是及物动词，其后接宾语，此处很明显缺少代词。分析句意可知，此处用it指代上文提到的the railway。
Later，engineers 68. (manage) t cnstruct railways in a system f deep tunnels(隧道)，which became knwn as the Tube.This develpment was nly pssible with the 69. (intrduce) f electric-pwered engines and lifts.The Central Lndn Railway was ne f the mst 70.

解析 考查时态。全文讲述的是发生在过去的事情，故用一般过去时。
解析 考查词性转换之动词变为名词。空格前是the，其后接名词。intrduce的名词形式是intrductin。
解析 考查词性转换之名词变为形容词。“ne f the＋形容词最高级＋可数名词复数”表示“最……的……之一”，此处应填success的形容词形式successful。

(certain) fun but the lifestyle is a little unreal.I dn’t want t have nthing else t fall back n when I can’t mdel any mre.”语篇解读 本文是一篇记叙文。16岁的萨拉作为一名模特表现出色，她父亲想让她放弃学业专心从事模特行业，但萨拉认为学业优先，不想在模特行业投入太多精力。
解析 考查动词的时态。此处为陈述客观事实，故用一般现在时。
解析 考查词性转换之形容词变为副词。此处应该用副词来修饰形容词fun，certain的副词形式为certainly。
