through...open up...
高中·外研版·选择性必修第二册
句型结构:As we break through the traditional boundaries,we will open up
a new world of possibilities.
易错点1:as引导时间状语从句时,主从句时态混淆

s引导时间状语从句表示“随着…”时,若主句用一般将来时(will+动词原形),从句常
用一般现在时表将来(主将从现)。

ties.(x)
正确表达:As we break through the traditional boundaries,we will open up anew world of possibilities..(√)

选择性必修第二册句型易错点精讲
核心知识点:
break through为动词短语,意为“突破:穿过”,作谓语时需注意时态和语态:若作名词,需
用a breakthrough。
典型例句对比:
典型错误:We need to make a break through the difficulty..(x,名词形式错误)
正确表达:We need to make a breakthrough in the difficulty.(√)
真题链接(外研版高中选择性必修第二册基础训练):
Scientists have_(break through)in the research on AI,which will benefit humanity
答案:broken through
解析:此处需用现在完成时(have+过去分词),break through的过去分词为broken through,
意为“取得突破”。
易错点3:open up的语义及搭配不当
核心知识点:
open up意为“打开;开创;开拓”,常见搭配为open up a world/opportunity/possibility等,
后接of短语表所属。
典型例句对比:
典型错误:We will open up a new possibility world.(×,语序错误)
正确表达:We will open up a new world of possibilities.(√)
真题链接(外研版高中选择性必修第二册单元测试):

随进行:易与引导原因状语从句(表“因为”)混淆。

伴随)

突破…)
As we need new possibilities,.we must break through traditional boundaries.(原因状语从句:因为需要
…)
