案例探究
1.I"d like very much to come but I had an examination on Monday morning.
（NMET 2000春季）
解析：此题为五星级题。考查时态一致。had 改为have。动词的时态要与上下文的时态保持一致。根据全文时态，此句为一般现在时，所以had 应为have。
2.Now someone at home reads instead. （NMET 1999）
解析：此题为五星级题。考查代词上下文指代一致。someone 改为everyone或everybody。 本文意思是：既然电视机卖了，全家每个人都没法看了，现在都改成读书了。根据代词指代内容要与指代的意义上一致的原则，这里指代的是家里的每一个人即：everyoneeverybody。
3.A seeing-eye dog is a special dog that help blind people walk along the streets and doing many other things.
解析：此题为五星级题。此题考查代词所指代的内容要与该先行词保持一致的原则。A special dog 是先行词，that 指代a special dog,在定语从句中作主语，所以help 应与先行词在数上保持一致。help改为helps。
e.g. He is one of the students who have been to the Great Wall in his class.
He is the only one of the students who has been to the Great Wall in his class.
4.Dad, as well as Mom and I, are with you.
解析：此题为四星级题。此题考查主谓一致原则。 as well as 连接两个主语，谓语动词应与前面的主语一致。are改为is。
e.g. Tom as well as two of his students was invited to the party.
The teacher as well as the students likes the paintings.
as well as, together with, with, like, but ,except ,including 等介词短语连接两个主语，其保持一致原则是与其前的主语一致。
5. I"d like to your pen friend
解析：此题为五星级题。考查谓语动词与主语主谓一致的原则。to 后加be。该句中like 是及物动词，意为想要。通常用would like to do 的形式，是一种比较委婉客气的说法。如：I"d like to go there alone. 本题题意：我想做你的笔友。从结构上看，I"d like to 后缺动词，从意义上判断应是be或become。所以，应在like 之后加上动词be或become。
锦囊妙计
短文改错中所涉及到的一致关系主要包括主谓一致、时态一致、代词指代一致。谓语动词的单、复数形式要与句子主语保持一致；动词的时态要与时间状语或上下文的时态保持一致；代词所指代的内容要与该先行词在词性和数方面保持一致，要与其自身的指代在意义上保持一致。
