解答 16.答案 faster
由第一句可知,这里是胖人和瘦人在记忆力和思维能力方面进行比较,故应是faster.
17.答案 whose
"The study was based on almost 6,500 civil servants"是句子主干,"____age are between 50 and60"应是定语从句,其先行词是6,500civil servants,关系词在定语从句中作定语,故应是whose.
18.答案 was taken
their blood pressure与take之间是被动关系,又由连词and可知,它连接的应是两句话,故应用was taken.
19.答案 used
"In addition,they were asked to perform mental tests three timesduring the decade"为句子主干,"____to assess memory and other cognitive skills"应是定语,又mental tests与use之间是被动关系,故应是used.
20.答案 Of/Among
句意:在这项研究中,共有6401公务员参与,其中582(9%)人是肥胖的.故这里应是Of/Among.
21.答案 additional
这里应用addition的形容词来修饰名词factors,故此处应是additional.
22.答案their
句意:研究者发现,肥胖的人比他们比较瘦的同事更容易丧失精神力量,而那些患病的肥胖人失去记忆力和思维能力应是最快的.故这里应是their.
23.答案The
latter常与the搭配,意思是"后者".
24.答案 but
前后两句是转折意味,故这里应是but.
25.答案 it
it作形式主语,"that ahealthy diet,regular exercise,not smoking and controlling blood pressure canhelp us keep fit"作真正地主语.
点评 语法填空答题技巧
考生在对题目进行作答之前,要先对题干进行详细阅读,检查题目中是否有提示词语存在;而后判断出所填词语在句子中所充当的句子成分,例如,主语、谓语等;最后根据其所充当的句子成分,加之其所处句子的语态等,选择词语的正确形式,例如,动词的现在分词或者过去分词,或者形容词的比较或者最高级的使用等.
在句子中没有提示词或者标志词存在时,考生要根据句子中所填词语的位置,判断所填词语的词性,例如,连接词、定冠词或者不定冠词、代词或者介词等.定冠词以及不定冠词的位置通常在名词之前,起到对名词进行限制的作用.而代词则分为形容词性物主代词、名词性代词、指示代词和不定代词等.在运用介词的时候,往往考查介词的固定搭配,其中包括动词、形容词等与介词的搭配.
语法填空的题目虽然难度相对较大,考查范围相对较广,考生失分现象较为严重,但是只要考生能够清楚地了解这类题目的命题特点和命题规律,掌握答题的技巧,在备考的过程中有针对性地多加练习,熟练语法的运用,及时对经验进行总结,加强在语篇情境下的语法应用能力,在考试中就能提高语法填空题的准确率,取得较为理想的成绩.
