一、时间状语判断法
动词的时态，顾名思义就是指动作或状态在不同时间条件下的动词形式，因此时间状语是确定动词时态的最直接的决定因素。
【例1】　Silk had become (become) one of the primary goods traded along the Silk Road by about 100 BC.
分析：句中by about 100 BC是表示过去的时间状语，当时间状语是“介词by (不迟于，不晚于)＋过去的某一时间”时，表示动作发生在“过去的过去”，谓语动词应用过去完成时。故填had become。
【例2】　In the last few years, China has made (make) great achievements in environmental protection.
分析：句意：在最近几年里，中国在环境保护方面取得了巨大成就。句中的时间状语是In the last few years，表示动作“从过去某一时间一直持续到现在”，应用现在完成时；且主语China为单数形式。故填has made。
二、固定句式判断法
英语中有一些句式的时态常常是固定的，如果题干中出现这类句式，应注意根据规则选用适当的时态。常见的固定句式如下：
(1)be doing...when...，when前面的句子常用过去进行时，when后面的句子常用一般过去时。
(2)It is/has been＋时间段＋since...表示“自从……以来已……”，主句用现在完成时或一般现在时，从句用一般过去时。
(3)祈使句＋and/or＋陈述句，陈述句常用一般将来时。
(4)It is (high/about) time that sb....，that后面的句子要用一般过去时或should＋动词原形。
二、固定句式判断法
英语中有一些句式的时态常常是固定的，如果题干中出现这类句式，应注意根据规则选用适当的时态。常见的固定句式如下：
(1)be doing...when...，when前面的句子常用过去进行时，when后面的句子常用一般过去时。
(2)It is/has been＋时间段＋since...表示“自从……以来已……”，主句用现在完成时或一般现在时，从句用一般过去时。
(3)祈使句＋and/or＋陈述句，陈述句常用一般将来时。
(4)It is (high/about) time that sb....，that后面的句子要用一般过去时或should＋动词原形。
【例3】　It is the first time that I have been (be) to Beijing.
分析：句意：这是我第一次去北京。提示词为be动词，设空处在句中作谓语，再根据固定句式It is the first time that sb. have/has done ...确定使用现在完成时。故填have been。
三、语境综合判断法
当题干中无时间状语及参照动词，或时间状语和参照动词都不能确定所填词动作的时态时，所填动词的时态由题干的具体意思或动作所发生的语境来决定。
【例4】　“This really excites scientists，” Carle Pieters, a scientist at Brown University, says，“because it means (mean) we have the chance to obtain information about how the moon is constructed.”
分析：根据语境可知，这是Carle Pieters说的话，结合excites可知，应用一般现在时，主句是一般现在时，because引导的从句也应用一般现在时，主语是it，该处谓语动词用第三人称单数形式。故填means。
【例5】　(2023·北京卷)I turned up at the appointed hour for a dinner, only to find that no other guest had arrived (arrive) and my hostess was still in her sleeping suit.
分析：句意：多年以后，搬到法国后，我在约定的时间赴宴，却发现没有其他客人到场，女主人还穿着睡衣。根据语境可知，“客人没到场”这一动作发生在“我到场”之前，即“过去的过去”，故用过去完成时。故填had arrived。
四、时态呼应判断法
时态呼应原则也是我们确定具体时态的常用方法。
【例6】　He said that one of the boxes generated (generate) around $13,500 in revenue a month and cost only about $400 to rent.
分析：句意：他说其中一个箱子每月收入约为13,500美元，租金仅为400美元左右。根据主句中的said可知，that引导的宾语从句时态也应用过去的某种时态，从句陈述客观事实，应用一般过去时。故填generated。

(2)含有be going to, be to, be about to等结构的复合谓语变为被动语态，其构成为“be going to (be to, be about to)＋be＋done”。
二、主动形式表示被动意义的几种情况
英语中有很多动词，如clean, sell, read, write, wash 等，当它们被用作不及物动词来描述主语特征时，常用其主动形式表示被动意义，主语通常是物；在这种情况下，常常和easily, well等副词连用。
This kind of cloth cleans easily.
这种布料容易清洗。
【点津】
(1)主动语态表被动意义强调的是主语的特征，而被动语态则强调外界作用造成的影响。
(2)感官动词feel, sound, taste, look 等后跟形容词、名词构成系表结构，无被动形式。
Junk food tastes delicious but it doesn't contain enough nutrition.
垃圾食品吃起来美味但营养不足。

Your composition still requires polishing/to be polished.
你的文章还需润色。
(4)在某些“主语(人/物)＋be＋形容词＋动词不定式”中，动词不定式的主动形式表示被动意义。这些形容词有nice, easy, fit, hard, difficult, important, impossible, pleasant, interesting等。
The problem is difficult to work out.
这个问题很难解决。(可看作省略了for me)
(5)be to rent/blame也属于主动形式表被动意义。

一、主语动词关系判断法
【例1】　Steam engines were used (use) to pull the carriages and it must have been fairly unpleasant for the passengers, with all the smoke and noise.
分析：句意：车厢由蒸汽机拉动，对于乘客而言在浓烟和噪音下乘车肯定是相当不舒服的。主语Steam engines和use之间是被动关系，且由句中的must have been可知，此处叙述的是过去发生的事情，设空处应用一般过去时的被动语态；又因主语是名词的复数形式，谓语动词应用复数形式。故填were used。
二、动词特点判断法
【例2】　This listening material, together with its CD-ROMs, sells (sell) well.
分析：句意：这些听力材料和它的CD光盘都很畅销。英语中有很多动词，如sell、 read、 write、 clean、 wash 等，当它们被用作不及物动词来描述主语特征时，常用其主动形式表示被动意义，主语通常是物；在这种情况下，常常和easily、 well等副词连用。此处句子的主语是This listening material，谓语动词应用第三人称单数形式。故填sells。
三、含有情态动词的被动语态
【例3】　The artist was sure he would be chosen (choose), but when he presented his masterpiece to the emperor's chief minister, the old man laughed.
分析：句中主语he与choose之间是被动关系，应用被动语态，且情态动词would后跟动词原形。故填be chosen。
