海墘(qiān)街是槟城过去和现在的缩影。
这里既有大量历史古迹也不乏现代建筑。
Georgetown(乔治市)是槟城岛中心城市Malaysia(Malaysian)马来西亚(马来西亚的,人)东南亚著名旅游国家,农业资源丰富,著名景点有吉隆坡(首都)沙巴(登东南亚第一高峰,丛林探险)马六甲(海上生命线)热浪岛(游泳潜水)槟城(东方珍珠的美誉)-----此段老师根据教材与网页信息整理2.this morningthis morning是典型的一般过去时标志性时间状语,老师又写下了几个同样是一般过去时标志性时间状语:(long) ago,(the day before)yesterday,last week/night/year,month...,in 1989,just now,at the age of...,one day,once upon a time,then(那时),on that day.练习:①当我看到那条蛇时,我非常害怕。
②早上八点时我正在吃早餐。
2.同学们仔细就会发现,第二题貌似并不应该用一般过去时表示。
当一句话既有一般过去时标志性时间状语又有现在进行时标志性时间状语(正在)时,我们称这个句子为过去进行时。
例句:When(一般过去时标志)we got to the top, it was raining really hard.正在则在汉语翻译中体现过去进行时的定义:①过去某个时间正在发生的动作强调过去某刻②过去某段时间正在发生的动作正在进行的东西练习:①当我正在清扫我的房间时,我的朋友给我打电话。
