01
名词形式变化
名词的形式变化主要有单数、复数、所有格的变化。
例：There are many students living at school，the______ (child) houses are all far from school.
由students一词可以判断出横线处应填复数，且作为houses的定语，所以应用其所有格形式，故答案为child的复合变化形式——复数的所有格children’s。
02
动词的形式变化
动词的形式变化比较多，有谓语的变化(时态、语态、语气)，有非谓语的变化(不定式、动名词、现在分词、过去分词)。
例：A talk_______ (give) tomorrow is written by Professor Zhang.
句中的is written是整句的谓语，所以横线所在的动词应当用作非谓语。从tomorrow可以看出，报告是“将来”作的，故用不定式;且报告是give动作的承受者，故可以判断出横线所在处用give的不定式被动式——to be given.
03
代词形式变化
代词形式变化通常是与人称变化有关的三大类五小类，即人称代词(主格和宾格)、物主代词(形容词性和名词性)、反身代词。另外还有几个不定代词的形式变化，如no one/none、other/another等。
例：The king decided to see the painter by ________(he).
由介词by可以看出，横线处应填反身代词himself。
04
形容词、副词比较级变化
英语中大部分形容词和表方式的副词都有原级、比较级和最高级的变化。构成比较级和级的方式，或通过加后缀一er和.est，或在词前more/less和most/least，且形容词的级还要冠以the。
例：I am _____ (tall)than Liu Wen．He is the tallest students in my class．
此题后句交代了LiuWen是班上最高的学生，那“我”肯定比他矮，所以不能用taller，只能用表示程度不如的“less tall”。
05
数词形式变化
数词的形式变化包括基数词、序数词，或加后缀一teen、ty的变化，甚至还有作分母用的序数词的单复数形式，以及one／two的特殊变化形式 once／twice
例：To my three sons I leave my seventeen horses．My eldest son shall take a half，my second son shall take a _______(three).
从上下文连续起来理解，这是一个分马的计划，大儿子分得a half，也就是“一半”或“二分之一”，那么二儿子应该得“三分之一”，所以要填入作分母的序数词“third”才能命中目标。
06
词的派生
词的派生现象在英语单词中是很常见的，派生现象主要发生在名词、动词、形容词、副词四种词中。这种题型还有可能检测学生对词根、前后缀、派生词的掌握。
例：Lious lost his wallet yesterday，so he was very____(happiness)．
在这道题中，学生很容易判断出该用形容词；钱包丢了，人应该是不开心的，所以要再加个前缀un，就成了unhappy。
07
固定短语结构
根据句中横线前后及整句来判断横线前后是否构成一个固定短语，但有时要对横线前或后的几个单词“视而不见”才能命中答案。（这种往往没有提示词，难度也会更大一些）
例1：The children were playing on the ground，enjoying____，dirty but happy.
从句中的happy可以 猜出孩子们是开心的，所以应用enjoy oneself短语，故其答案为themselves。
例2：His boss was____angry as to fire him．
如果“跳过”横线后面的angry，就可以发现这里用到一个关联短语so...as to...，所以，so是正解。
08
从句引导词
从句是此题型最为常见的一个方向，主要检测学生对引导词的掌握程度。
例1：He did not done_____his father had asked him to do．
审题可知，横线所在为宾语从句的引导词，此引导词在从句中充当宾语，且指物，所以是what。
例2：Those_____want to go to the village must sign here．
经过观察可以判断横线所在为定语从句的引导词，进一步观察可知先行词为those，且指人，所以只能填入who，在定语从句中做主语。
09
短语动词结构
短语动词是以动词为中心的两个或多个词构成的短语，此类短语中往往是动词与介词或副词连用的多些。
例1：The US consists____fifty states．
根据常识可知，美国由50个州组成，故横线处与前一词组合，表示“由......组成”，所以答案是of。
例2：Mrs Baker was ill，so her daughter had to ask for leave to take_____of her．
ask for live请假，生病需要人照顾，所以答案是care，与前后词构成take care of。
10
短语介词结构
短语介词即多个词的组合。起介词作用的短语，如：except for，due to等。
例1：Mr Smith took a plane to London____of taking a train.
此题中说到两种交通工具，所以可以理解此句有“坐……而不是坐……”的意思，故答案为instead，以构成介词短语instead of。
11
连词、关联短语结构
常用的连词有and，or，but，so，for，while等，常用的关联短语有both…and...，either…or...，neither…nor...，not only…but also...等。
例1：Little Wang Jun could not go to school，_____his family was too poor．
此处表示原因，引导的分句其实是一种解释说明，不是必然的因果关系，且前面有逗号隔开，所以填for。
12
冠词、介词和常用的副词
冠词只能是在a，an，the之间判断；常用的介词有in，at，on，before，during等，通常考查固定搭配；副词的量还是比较多，如：however，never，yet，much等。
例1：Jackie likes to drive at____ high speed．
这里考查的是不定冠词的习惯用法，答案为a，构成at a high speed，“以高速”开车。
例2：Old Tom’s grand daughter used to visit him_____Saturday afternoon．
Saturday afternoon是指定的某天下午，所以不用介词in，而用on才是正解。
13
上下文中出现的相关词
这一招是最为灵活的，但也是最难的。学生可以根据上下文关系和自己积累的知识，填入某个已出现的词，或其反义词，或其同类的某个词。
答案的线索可能在本句，可能出现在上下相连的一句，还可能出现在比较远的地方——上下段中与此段位置大体相当的句子。如果该横线出现在某段的首句，则线索可能在上下段的.首句；如果横线出现在某段的末句，则线索可能在上下段的末句，以此类推。
例：Tony____travelling abroad，but dislikes staying home watching TV．
由第二句话中的dislikes可以判断，此横线处应该是填其反义词likes。
上面的大家都掌握了之后，再分享一些比较好记忆的口诀和要点总结：
接不定式作宾语的动词
三个希望两答应：hope，wish，want，agree，promise
两个要求莫拒绝：demand，ask，refuse
设法学会做决定：manage，learn，decide
不要假装在选择：petend，choose
句子种类口诀
句子按用途分四大体，陈述疑问感叹和祈使。
陈述用来叙述一件事，疑问主要用来提问题。
祈使表达命令和请求，表达强烈感情感叹句。
上述九是句种之定义，祈使主语you被抛弃。
若将其变成否定形式，动词之前加don’t是正理
冠词基本用法
名词是秃子，常要戴帽子，
可数名词单，须用a或an，
辅音前用a，an在元音前，
若为特指时，则须用定冠，
复数不可数，泛指the不见，
碰到代词时，冠词均不现。
语法填空这个题型平时的时候一定要注意积累总结，它虽然考察语法，但并不是很深入系统的考察，所以积累技巧就可以啦。
