一、一句话的时态是通过谓语动词来反映的，由时间状语来决定的。所以划线部分如果有动词则第一反映是不是谓语：
一)如果是，谓语划线考法有三个1)主谓一致2)时态 3)被动(很简单) 记住一句话：谓语划线看主语，主谓一致看状语：如
The rise in the Commerce Department’s index of leading economic indicators suggest thatthe economy should continue its expansion into the coming months, but that themixed performance of the index’s individual components indicates that economic growth willproceed at a more moderate pace than in the first quarter of this year.
A suggest that the economy should continue its expansion into the coming months, butthat
B suggest that the economy is to continue expansion into the coming months but
C suggests that the economy will continue its expanding in the coming months, but that
D suggests that the economy is continuing to expand in the coming months, but that
E suggests that the economy will continue to expand in the coming month, but
此句划线部分则有谓语动词考的则的主谓一致的问题 主语为单数的rise 所以谓语应用单数
此题也考了另外的一个常考语法点but后是加平行结构还是转折连词作用，此题中是，转折词则要直接加主谓所以答案为 E
二) 如果不是，则为非谓语动词。常考在句首做状语逻辑主语为句子主语，或介词+分词其逻辑主语也为句子主语，在句尾表示伴随动作状态，伴随功能结果。当然还有其他用法但考的频率没上述点考的高。重点掌握上述考点可解决多于一半的分词题目如：
Reared apart from each other, a recent united states study showed strikingsimilarities in identical twins including many idiosyncrasies of behavior.
A Reared apart from each other, a recent united states study showed striking similarities inidentical twins including many idiosyncrasies of behavior.
B Reared apart from each other, striking similarities between identical twins that includemany idiosyncrasies of behavior were shown in a recent United states study.
C A recent United states study showed striking similarities in identical twins reared apartfrom each other that include many idiosyncrasies of behavior
D According to a recent United states study , identical twins reared apart from each othershowed striking similarities, including many idiosyncrasies of behavior.
E According to a recent united states study, identical twins showed striking similaritiesreared apart from each other, including many idiosyncrasies behavior.
此题从题目划线部分可以看出rear apart其逻辑主语为句子主语而study不能被分开来抚养 B
相似性也不能分开抚养 C 定语从句修饰要贴近先行词否则会引起争议，D为正确答案
二、划线部分有无代词，如果有80%都是错的，找其指代注意划线与未划线部分的协调
The only way for growers to salvage frozen citrus is to process them quickly into juiceconcentrate before they rot when warmer weather returns.
A. to process them quickly into juice concentrate before they rot when warmer weatherreturns.
B if they are quickly processed into juice concentrate before warmer weather returns to rotthem
C for them to be processed quickly into juice concentrate before the fruit rots whenwarmer weather returns
D if the fruit is quickly processed into juice concentrate before they rot when warmerweather returns.
E to have it quickly processed into juice concentrate before warmer weather returns androts the fruit.
此题考点有两个1) 代词指代错 物质名词为单数处理 citrus 2) the only way is to do 固定用法，所以答案为 E
