35、“达，计(表示动作或情况持续的时间)”。故填for。9industrial考查形容词。空后的use为名词，作for的宾语，所以应用形容词修饰名词。故填industrial。10the考查冠词。the修饰形容词最高级，at the earliest意为“最早”。故填the。课时练(二)一、主题语基拓展练 (一)主题词汇盘查 (已会词汇，在内打“”；欠熟练词汇，多翻阅识记)harmony beneficialcontribution protect development terrified drought destruction conservation emission hurricane r
