3. add up 是什么意思?它有哪些相似的重要搭配? 【教材原句】 Add up your score and see how many points you get. (p.1) 译文:然后把你的得分加起来,看看你得了多少分。 【用法归纳】 add up 主要有两个意思: (1) 加起来。如: You haven’t added the figures up right. 这些数字你没有加对。 The waiter added up the food check. 侍者把饭菜的钱算了一下。 (2) 有意义,有道理(主要用于口语中,且主要用于否定句)。如: His excuse just doesn’t add up. 他的借口完全站不住脚。 What he said doesn’t add up. 他说的话自相矛盾。 【有关归纳】 另外,还有以下相关短语和搭配值得注意: (1) add in 包括。如: Don’t forget to add me in. 别忘了把我也算上。 Would you add in these items, please? 请你把这些条款包括进去好吗? (2) add to 增加。如: This adds to our difficulties. 这增加了我们的困难。 It adds to my pleasure to see you here today. 今天在这里见到你我格外高兴。 (3) add up to ① 加起来等于,总计。如: The figures add up to 500. 这些数字加起来等于500。 The costs added up to 1 000 dollars. 费用总计为1 000美元。 The various costs add up to 220 yuan. 几项开支加起来总数达220元。 ② 总起来看说明了。如: Your long answer just adds up to a refusal. 你的冗长回答简直等于拒绝。 The evidence all adds up to a case of murder. 所有证据都说明这是一起谋杀案。 I don’t think these facts add up to anything. 我看不明白这些事实能说明什么问题。 (4) add(ed) to that [this] 而且,另外。如: Added to this,she had a wonderful ability to describe things. 除此之外,她还擅长于描绘事物。 【附注】类似“3+4=7”这样的算式,可用以下包含add的英语句子表达: Three added to four makes seven. Three and four add up to seven. If you add three to four, you get seven.
4. not…until…是什么意思?使用时应注意些什么? 【教材原句】 You want to see a very interesting film with your friend, but your friend can’t go until he / she finishes cleaning his / her bicycle. (p.1) 译文:你想同你的朋友去看一场很在趣的电影,但是你的朋友要等他(她)擦完自行车以后才能同你去。 【用法说明】 not…until…是英语中的固定句式,其意为“直到……才……”。如: Don’t leave till I come. 我来了你再离开。 He didn’t come until yesterday. 直到昨天他才来。 He didn’t go to bed until his wife came back. 直到他妻子回来他才睡觉。 I didn’t manage to do it until you had explained how. 直到你给我解释了理由,我才会做。 【几点注意】 (1) 该结构中的主句动词通常是终止性动词,若为延续性动词,则可能导致含义有变化。如: I won’t stay here till [until] Monday. 我在这儿待不到星期一(即不到星期一就走)。 He didn’t wait until I returned. 他没等到我回来(即没等我回来他就走了)。 (2) 它用于it is (was)…that…这类强调句型时,其基本结构是:It is (was) not until…that… 直到……才……。如: It was not until yesterday that I noticed it. 直到昨天我才注意到此事。 It was not until I got to the station that I missed my wallet. 直到车站我才发觉钱包不见了。 It was not until she took off her dark glasses that I realized she was a famous film star. 直到她取下墨镜,我才意识到她是一位著名影星。 It was not until I met you that I knew real happiness. 直到我遇到你以后,我才真正体会到幸福。 (3) 若将not until置于句首,其后的句子或主句则要用倒装句式。如: Not until the rain stopped did he leave the room. 雨停了之后他才离开这房间。 Not until that evening was she able to recover her self-control. 一直到那天晚上,她才恢复了自我控制的能力。 Not until I began to work did I realize how much time I had wasted. 直到我参加工作,我才意识到我曾浪费了多少时间。 Not until he received her letter did he fully understand the depth of her feelings. 他直到收到她的信之后才充分理解她的感情有多深。 引用地址: |
