Question Knowledge points 3 课文原句： As the United States prepares for Hurricane Florence, an even bigger ocean storm, Super Typhoon Mangkhut, is set to hit Southeast Asia. prepare 的基本词义是“准备”，而 prepare for 表示“为……做准备”。因此，以下两个英语句子的意思有很大差别： Mr. Johnson is preparing the final examination of the term. 约翰逊先生正在为本学期的期末考试命题。 The students are preparing for the final examination of the term. 学生们正在为本学期的期末考试做准备。 人们在 prepare the final examination 和 prepare for the final examination 中做的事情是完全不同的：Mr. Johnson 是在“命题”，the students 是在“备考”。 知识点1：prepare & prepare for ⇔ 为……做准备 课文原句： As the United States prepares for Hurricane Florence, an even bigger ocean storm, Super Typhoon Mangkhut, is set to hit Southeast Asia. 再比较下面的例子： A： She has to prepare lessons in the evening. 她不得不在晚上备课。 It was difficult to find time to prepare for the parties. 很难找到时间为聚会做准备。 B： I was just preparing dinner when the phone rang. 电话响的时候，我正在准备晚餐。 I hadn’t prepared for the job interview adequately. 我没有为求职面试做充分的准备。 知识点1：prepare & prepare for ⇔ 为……做准备 知识点2：bring up & bring down ⇔ 抚养；减少 课文原句： It was reported that the storm flooded streets, brought down trees and cut electric service. ①bring up 常表达 “抚养长大”“养育”的意思。例如： She brought up three children. 她抚养了三个孩子。 He was brought up by his uncle. 他是由他的叔叔养大的。 ②bring down 常表达“减少”“降低”“使（飞机）着陆”“击落”等意思。例如： We aim to bring down the price of our computers. 我们打算降低计算机的价格。 Twelve enemy planes were brought down. 有12架敌机被击落。 The pilot managed to bring the plane down in the field. 飞行员设法将飞机降落在田里。 知识点3：hope & expect ⇔ 希望；期望 课文原句： The super typhoon is expected to reach the Philippines Saturday at the start of the harvest season in Luzon. ①hope 可以用作动词和名词，表示“希望”，常出于没有把握、没有根据的个人希望或愿望。 We hope that the weather will become fine soon. 我们希望天气很快变好。 She hopes to get a place at Tsinghua University. 她希望能被清华大学录取。 We hope for good results. 我们希望有好的结果。 The future is not without hope. 未来并非没有希望。 知识点3：hope & expect ⇔ 希望；期望 课文原句： The super typhoon is expected to reach the Philippines Saturday at the start of the harvest season in Luzon. ②expect 则只能用作动词，表示“等待”和“期望”。expect 的正式程度高于 hope，是由于有把握和根据的期望。 I expect a visit from Mr. Zhang since he has written me that he is coming. 张先生写了一封信给我，说他就要来，所以我在等他来。 I expect that it will rain. 我预计会下雨。 I expect to win the game. 我预计会赢得比赛。 I expect John to win the game. 我预计约翰会赢得比赛。 Grammar 4 过去将来时 过去将来时 在英语时态中，过去将来时表示从过去的某一时间来看将来要发生的动作或呈现的状态。过去将来时主要出现在宾语从句中。过去将来时的构成方式主要包含以下四种： ①should/would + 动词原形，例如： I didn’t know if he would come. 我不知道他是否会来。 We asked him where we should go to work next month. 我们问他我们下个月去哪儿干活。 ②was/were going to + 动词原形，例如： He didn’t tell me if he was going to work as a teacher. 他没有告诉我他是否会做教师工作。 过去将来时 在英语时态中，过去将来时表示从过去的某一时间来看将来要发生的动作或呈现的状态。过去将来时主要出现在宾语从句中。过去将来时的构成方式主要包含以下四种： ③was/were + verb-ing，例如： Jack said he was leaving tomorrow. 杰克说过他明天走。 ④was/were + 动词不定式，例如： Nobody knew if he was to come. 没人知道他是否会来。 过去将来时 其他用法包括以下几种： ◆ was/were going to + 动词原形，可表示未能实现的过去将来时间的动作。 例如： Last Sunday we were going to go for a picnic, but it rained. 上周日我们本打算去野餐，但是下雨了。 I was going to finish my homework last night, but my friend came so I didn’t have time. 昨晚我本打算完成我的作业，但我的朋友来了，所以我没有时间。 过去将来时 其他用法包括以下几种： ◆ was/were + 动词不定式完成式，表示过去将来时的安排，后来被取消了，没有实现，并可以与表示现在、过去或将来的时间状语连用。 Compare: He said that we were to leave at 6 p.m. 他说我们会在下午 6 点动身。 We were to have left at 6 p.m. last night. 我们原本会在下午 6 点动身。 We were to have left at 6 p.m. tomorrow. 我们原本会明天下午 6 点动身。 We were to have been in France now. 我们原本会此时在法国了。 过去将来时 其他用法包括以下几种： ◆ was/were about to do 表示过去将来时，含义是“即将或刚要做某事”，与“was/were + 动词不定式”含义不同。 例如： We were about to start when it rained. 我们刚要开始，突然下雨了。 He was just about to leave when he saw his mother. 他正要动身离开，突然看到了妈妈。 语法练习 示例：he said—he wash the car—tomorrow He said that he would/was going to wash the car tomorrow. 1.they said—they swim—the day after tomorrow They said that they would/were going to swim the day after tomorrow. 2.they tell me—yesterday—they visit the museum—next weekend They told me yesterday that they would/were going to visit the museum next weekend. 语法练习 3.we play basketball—last Sunday—but it was too windy We were going to play basketball last Sunday, but it was too windy. 4.it was 1491—Columbus discover America—in the following year It was 1491; Columbus would/was going to discover America in the following year. 5.they reply—last month—they come to visit us—next year They replied last month that they would/were going to come to visit us next year.
