(现在仍是) / Our village became a tourist attraction in 2015. (只说过去)(我们村已成为旅游景点。(现在仍是)/我们村在 2015 年成为旅游景点。(只说过去)) 四、易错提醒 1. used to do sth. 表示过去常常做某事,现在不做了;be used to doing sth. 表示习惯于做某事;be used to do sth. 表示被用来做某事。三个结构要分清。 2. used to 的否定式是 did not use to 或 used not to,一般疑问句用 Did…use to…?,注意 use 后面不加 d。 3. 现在完成时表示过去发生的动作对现在造成的影响或结果,常与 already、yet、ever、never、just、since、for、over the past… 连用;与 yesterday、last year 等明确过去时间连用时要用一般过去时。 4. 现在完成时由 have / has + 过去分词构成,主语是第三人称单数时用 has,常见错误是直接用动词原形或过去式。 五、练习检测 建议用时 15 分钟。先合上笔记独立完成,再对照文末参考答案,把出错的单词和短语在笔记上标出来,当天再读三遍。 一、用所给单词的适当形式填空 每空只填一个单词,注意时态与结构。 1.
