She is just on my left. A. next to B. in front of C. behind D. across from 解析 根据设空处后的“她就在我的左边”可推断,我紧挨着琳达坐,next to意为“紧挨”,符合本题语境,故答案为A. 答案 A 知识点二across的用法和延伸 教材原文 It's across from the park.它在公园对面. across from 表示“在······对面”,和opposite同义.如: The bank is across from the school.银行在学校对面. 拓展across可以作介词,也可以作副词,意为“穿过;越过”,通常表示从物体表面穿过.如: Can you swim across?你能游过去吗?(across作副词) I'm helping an old man walk across the street.我正在帮助一位老人过马路.(across作介词) 辨析across, through, over across 表示从物体的表面穿过,常与之搭配的词有street、road、river等 through 表示从某个立体空间穿过,常与之搭配的词有city、forest、park、tunnel、window 等 over 表示从某物的上方越过或跨过 注意cross也表示“穿过”,但它是动词,而across是介词,walk/go across 同cross.如: Be careful when you go across the street.=Be careful when you cross the street.你过马路的时候要小心一点. 例(2020河北石家庄石门实验学校四月月考)-Look! A little child is in the middle of the street. It's too dangerous. -Let's help him go________ the street. A. across B. cross C. through D. along 解析 此处要填的是介词,不是动词,先排除选项B;答语的含义是“让我们帮助他过马路吧”,和the street搭配,表示“过马路”要用across,故答案为A. 答案A 知识点三in front of的用法和延伸 教材原文-Are there any restaurants near here?这附近有餐馆吗?-Yes, there's one in front of the post office.有,邮局前面就有一家. in front of 是固定搭配,意为“在······前面”.如: I can't see the blackboard because a tall boy is sitting in front of me. 我看不到黑板,因为一个高个子男孩正坐在我的前面. 辨析in front of 和 in the front of的区别 in front of 指某场所或空间之外的前面 in the front of 指某场所或空间之内的前面 There is a big tree in front of the classroom.教室前面有一棵大树.(树在教室的外面) There is a
