sth.(直接接宾语)。 高中必修2冀教版 寒假专版 ·精讲：feature作动词时，意为“以…为主要内容”，如The show features new artists.(这场演 出以新艺术家为特色。) ·例句：This smartphone features a high-quality camera.(这款智能手机的特色是高质量摄像头。) ·真题链接：The new model (以…为特色)a longer battery life.(答案：features) 9.download/.daUn'laud/v.下载 ·易错点：易混淆词性，误用作名词时加ing(downloading),原形不可作名词。 ·精讲：download作动词，名词形式为downloading(动名词)或download(美式口语中可作名 词，但教材中常用downloading)。 ·例句：I

software every week.(答案：update) ll.despite/d'spait/prep.即使；尽管 ·易错点：易误与though混淆，despite是介词，后接名词，though是连词接从句。 ·精讲：Though it rained heavily,.we went out.=Despite the heavy rain,we went out.. ·例句：Despite being tired,he finished the work.(尽管累，他还是完成了工作。) ·真题链接： the bad weather,,the sports meeting was held as planned.(答案：Despite) 12.credit/'kredrt/h.信用：信誉 ·易错点：易混淆“学分”含义，固定搭配get credit for
