1. 时态大侦探:看时间信号词
• 看到"since"→现在完成时(例:Since this time, the desert has received rain. [1](@ref))
• 遇到"yesterday"→一般过去时(例:When I arrived in Yangshuo... [18](@ref))
• "over the years"→现在完成时(例:friends I have made over the years [17](@ref))
口诀:时间线索是路标,过去现在未来要抓牢!
2. 非谓语变形术:to do/doing/done
• 介词后接动名词(例:by noting that... 17 )
• 表目的用不定式(例:to cool the house 18 )
• 被动完成用过去分词(例:a study conducted by... 18 )
口诀:介词后面ing跳,目的前面to带跑,被动完成用ed包!
3. 主谓一致躲猫猫
• 集体名词看整体(例:The committee is discussing...)
• "there be"就近原则(例:There is a boy and two girls 48 )
• 定语从句跟先行词(例:six are stable 17 )
口诀:单数复数别打架,先行词是老大!
4. 虚拟语气穿越术
• 与过去事实相反→would have done(例:many people would have died 62 )
• 建议/要求用(should) do(例:cars should be banned 62 )
口诀:虚拟世界玩穿越,should隐身要察觉!
原形 | 过去式 | 过去分词 | 现在分词 | 易错点 |
---|---|---|---|---|
lie(躺) | lay | lain | lying | 别和lie(说谎)混淆 |
hang | hung(挂) | hanged(绞刑) | hanging | 两种含义不同形 |
find | found | found | finding | 别写成fund(基金) |
cost | cost | cost | costing | 过去式≠原形+ed |
定位动词坑位:看是否有并列连词(and/but/or)连接其他动词
判断时态语态:找时间状语/被动标志(be+done)
检查主谓一致:单数第三人称要加s(例:He receives rain [1](@ref))
记住这个公式:
时态信号词 + 句子结构分析 + 主谓连连看 = 动词填空稳赢局!
试试这道题:The report suggests that cars with large emissions __1.___ (ban). (答案:should be banned [62](@ref))
