着眼点1 熟记连词用法,做出正确选择
[典例1] (2016·四川高考)__66__ it cried, she rocked it back and forth and gave it little comforting pats.
分析:句意:当它(熊猫宝宝)哭泣的时候/如果它(熊猫宝宝)哭泣,熊猫妈妈会前后摇晃熊猫宝宝,而且会轻轻地拍它。根据语境可知,此处为时间或条件状语从句,故填When/If。
[典例2] (2018·北京高考单选改编)________ we don't stop climate change, many animals and plants in the world will be gone.
分析:句意:如果我们不阻止气候变化,那么世界上的很多动植物都将消失。空格处引导条件状语从句,故填If。
[典例3] (2016·浙江高考单选改编)________ online shopping has changed our life, not all of its effects have been positive.
分析:句意:尽管网上购物改变了我们的生活,但并非它的所有影响都是积极正面的。此处引导词引导让步状语从句,应用While/Although/Though。
[典例4] (2018·天津高考单选改编)Let's not pick these peaches until this weekend so ________ they get sweet enough to be eaten.
分析:句意:让我们这个周末再摘这些桃子吧,这样的话,它们吃起来就变得足够甜。此处是so that引导的目的状语从句,表示“以便”。故填that。
着眼点2 理清逻辑关系,避免连词误用
[典例1] (2015·陕西高考)My only mistake was that I dropped some on the floor after I was packing them up.
分析:句意:我唯一的错误是在我打包的时候,把一些(饼干)掉在了地上。此处状语从句的连词表示“当……时候”,故after→when/while。
[典例2] (2015·浙江高考)If I was only a child when I studied in that classroom, I will never forget it.
分析:句意:尽管我在那间教室学习时只是个小孩,但我永远不会忘记那间教室。此处的从句为让步状语从句,连词表示“尽管”,故If→Although/Though。
着眼点3 排除汉语干扰,避免连词重复
[典例1] (2016·全国卷Ⅰ)Though not very big, but the restaurant is popular in our area.
分析:汉语可以说“虽然……,但是……”,但英语中though/although与but不能连用,故去掉but。
[典例2] (2019届高三·牡丹江模拟)Every time when he arrived home at the end of the day, we'd greet him at the door.
分析:汉语可以说“每次当……时候”,但英语中every time和when同为连词,不能同时引导一个状语从句,故去掉when。
