语法填空和短文改错这两种题型主要是从词法、句法和行文逻辑三个角度考查考生在语篇中综合运用英语的能力，同时兼顾句型结构、习惯搭配等。相对于词法、句法来说，行文逻辑题是考生失分最多的题目。究其原因，这类题目的解题信息不局限于某句或某个句群，大多是需要从全文的角度去审视、去思考，对于这类较难题目，考生在做题时，一定要注意以下三点：
一、注意时态是否一致
有目的地去检查文中的每一个谓语动词的时态与上下文、语境以及该句的时间状语是否相一致。若全文都是在使用过去时态，则考查角度一般就是针对过去时态的。
[典例1] (2016·全国卷Ⅰ)So it was a great honour to be invited backstage at the notforprofit Panda Base, where ticket money helps pay for research. I __62__ (allow) to get up close to these cute animals at the 600acre centre. From tomorrow, I will be their UK ambassador ...
[易误点拨] 分析句子成分可知句子缺少谓语动词，需要考虑其时态、语态及主谓一致。I与allow之间是被动关系，故用被动语态；又因上一句主句用过去时，可确定此句也用过去时。再根据主语I，可知应填was allowed。本题容易受下文将来时态的影响而错填别的时态。
[典例2] (2016·全国卷Ⅰ)My uncle is the owner of a restaurant close to that (→where) I live. Though not very big, but (去掉but) the restaurant is popular in our area. It is always crowded with customers at meal times. Some people even had (→have) to wait outside. My uncle tells me that the key to his success is honest (→honesty). Every day he makes sure that fresh vegetables or (→and) high quality oil are using (→used) for cooking. My uncle says that he never dreams (∧of) becoming rich in the (→a) short period of time. Instead, he hopes that our (→his) business will grow steady (→steadily)．
[易误点拨] 全文的时态为一般现在时，第四句中用了过去时had，应该引起重视，重点核查。因为没有具体的时间状语，故此处需将一般过去时改为一般现在时。
