If people have problems, they should try to keep them to themselves.keep... to oneself意为“保守秘密”例如：One must keep such interests to oneself.有这类爱好不该让人知道。We should keep their worries to themselves.我们应该为他们的忧虑保守秘密。重点词句精讲6. Problems and worries are normal in life.①worry 指 “烦恼,忧愁,忧虑”意思时是不可数名词。例如：My chief worry is that he doesn’t have experience. 我的主要忧虑是他没有经验。②worry意为“令人忧伤的人或事”时是可数名词，复数形式worries。例如：Her happiness at seeing him submerged her former worries. 她看到他非常高兴，顿时完全忘记了先前的烦恼。③worry作及物动词，意为“使担心”；做不及物动词，意为“ 担心”。常用搭配为：worry about / over sth / sb意为“担心某事/某人”。例如：Your worry is always triggered by some external event or happening.你总是为一些外因或事情而烦恼。 Don’t worry, he'll be alright. 别担心，他不会有事的。 I did not want to worry my friend. 我没想麻烦我的朋友。重点词句精讲7.

In English, we say that sharing a problem is like cutting it in half. 在英语中，我们说与人分担一个烦恼就像把麻烦分成两半。①share 是“分享；分担；共同承担”的意思。例如：share a room with someone 与某人同住一个房间share a book 同看一本书share a taxi 同坐一辆出租车Yes, I want to share my life with you. 是的，我想和你共享生活。重点词句精讲②cut…in half… “把……切成两半”“把……一切为二”，cut 意为“切、剪”。in half/ halves 是一种固定结构，此处in表示状态。例如： Please cut the orange in half. Now, all the oranges are in half. 10. So you’re halfway to solving a problem just by talking to someone about it!你只要跟人聊聊这个问题，你的问题就解决了一半。 be half way to… 表示“完成了或者做了事情的一部分”，其中to为介词。例如： we’re still only halfway to finishing the job.我们才仅仅完成了工作的一部分。句中的by在这里表示方式，“通过……办法；使用……方式”的意思。例如： A： How do you study for a test? B: Well, most of time by going over the notes and reading the textbook. 语法知识精讲if 引导条件状语从句1. 条件状语从句的概念：在句子中作条件状语的从句称为条件状语从句，作用就是用来说明主句在什么条件下才会发生。例句： If you study, I’ll be happy. （you study是I’ll be happy发生的条件或前提）If you wear jeans to school, you’ll be sorry. （you wear jeans to school是you’ll be sorry发生的条件或前提）If you get up late, you’ll be late. （you get up late是you’ll be late发生的条件或前提）If you eat too much, you’ll be fat.（you eat too much是you’ll be fat发生的条件或前提）语法知识精讲 2. 要注意的问题：主将从现原则：在英语里, 当句子的主句为将来时态时, 它所引导的时间状语从句和条件状语从句都使用一般现在时来表示将来时。主句的将来时态并不仅限于will＋动词原形构成的一般将来时,还包括be going to＋动词原形、be doing所表示的一般将来时以及我们以后会学到的其它的将来时态。例如:What is he going to do when he grows up? 他长大了想干什么？We are leaving for Xiamen tomorrow if it doesn’t rain. 如果明天不下雨, 我们就去厦门。We will buy that microwave next week if its price keeps going down. 如果价格持续下降,下个礼拜我们就买那台微波炉。语法知识精讲3. if引导的条件状语从句引导条件状语的词有很多，最常见的是if结构：If +从句, 主句。用法(1)if引导条件状语从句, 意为“如果、假如”, 主句不能用be going to表示将来, 而应该用shall, will。e.g. If you leave now, you are never going to regret it. (错误) If you leave now, you will never regret it. (正确)(2) if “如果”, 引导条件状语从句, 主句用一般将来时, 从句则用一般现在时，如： If it rains tomorrow, I shan’t climb the hills.【注意】 宾语从句中的if与条件状语从句if的区别。宾语从句中的if意思是“是否”，相当于whether, 引导宾语从句, 时态需根据语境确定。I don’t know if it will rain tomorrow. 我不知道明天是否会下雨。语法知识精讲(3)有时，我们可以使用并列结构的祈使句来表达if引导的条件句。例如：If you set your alarm clock, you won’t oversleep.如果你上闹钟, 你就不会睡过头了。=Set your alarm clock, and you won’t oversleep.If you give him an inch, he will take a mile. 他会得寸进尺。=Give him an inch, and he will take a mile.If you don’t give him some food, he will starve.如果你不给他一点吃的, 他就会饿死。=Give him some food, or/else he will starve.语法知识精讲在阅读英文文章时, 我们有可能看到这样的句子：If you will take the trouble to read his letter carefully, you will see what he means. 如果你肯花一些时间来认真读他的信，你就会明白他是什么意思了。在if-分句中用“will＋动词原形”并不单纯表示将来意义，这里的will是个表示“意愿”的情态动词, 相当于be willing to(愿意)。要注意这种带“will＋动词原形”的if-分句在某些场合是不可以随便用的, 比如我们可以说：If he gets my letter in time, he’ll be able to change his plans. 如果他及时收到我的信, 他就能改变他的计划。却不可以说成：If he will get my letter in time, he’ll be able to change his plans.语法知识精讲be＋doing形式: 用现在进行时态表达将来，主要意义是表示按计划、安排即将发生的动作，常用于位置转移的动词, 如go、come、leave、start、arrive等, 也可用于其它动态动词。如：The president is coming to the UN this week. 总统这周将到联合国来。We are moving to a different hotel the day after tomorrow. 我们后天将换一家宾馆。在英语中, 有相当多的动态动词都可以用现在进行时表示将来。例如：Dinner is ready. We’re having fish for dinner. 晚饭好了, 今晚我们吃鱼。I’m spending my holidays in Singapore this year. 今年我要去新加坡度假。Tom isn’t finishing his high school until next year. 汤姆明年才高中毕业。1. If you go to the party, you' I have a great time假如你去参加派对,你会过得很快乐2. If you do, the teachers won t let要是你这样做,老师将不会让你进3. If you do, you' li be sorry要是你这样做,你会遗憾4. If you don' t do this now, I' ll never do it.要是你现在不做这件事情,我将永远不会做。5. If we do that, more people will want to play the game.要是我们做那件事,更多的人都会想玩这个游戏。6. You can come with us if you want.只要你想,你就可以和我们一起来【单元目标语句回顾】读一读 练一练基础夯实7. What will happen if they watch a video at the party?假如他们在开派对时看视频,会发生什么呢?8.

B: Well, most of time by going over the notes and reading the textbook. 语法知识精讲if 引导条件状语从句1. 条件状语从句的概念：在句子中作条件状语的从句称为条件状语从句，作用就是用来说明主句在什么条件下才会发生。例句： If you study, I’ll be happy. （you study是I’ll be happy发生的条件或前提）If you wear jeans to school, you’ll be sorry. （you wear jeans to school是you’ll be sorry发生的条件或前提）If you get up late, you’ll be late. （you get up late是you’ll be late发生的条件或前提）If you eat too much, you’ll be fat.（you eat too much是you’ll be fat发生的条件或前提）语法知识精讲 2. 要注意的问题：主将从现原则：在英语里, 当句子的主句为将来时态时, 它所引导的时间状语从句和条件状语从句都使用一般现在时来表示将来时。主句的将来时态并不仅限于will＋动词原形构成的一般将来时,还包括be going to＋动词原形、be doing所表示的一般将来时以及我们以后会学到的其它的将来时态。例如:What is he going to do when he grows up? 他长大了想干什么？We are leaving for Xiamen tomorrow if it doesn’t rain. 如果明天不下雨, 我们就去厦门。We will buy that microwave next week if its price keeps going down. 如果价格持续下降,下个礼拜我们就买那台微波炉。语法知识精讲3. if引导的条件状语从句引导条件状语的词有很多，最常见的是if结构：If +从句, 主句。用法(1)if引导条件状语从句, 意为“如果、假如”, 主句不能用be going to表示将来, 而应该用shall, will。e.g. If you leave now, you are never going to regret it. (错误) If you leave now, you will never regret it. (正确)(2) if “如果”, 引导条件状语从句, 主句用一般将来时, 从句则用一般现在时，如： If it rains tomorrow, I shan’t climb the hills.【注意】 宾语从句中的if与条件状语从句if的区别。宾语从句中的if意思是“是否”，相当于whether, 引导宾语从句, 时态需根据语境确定。I don’t know if it will rain tomorrow. 我不知道明天是否会下雨。语法知识精讲(3)有时，我们可以使用并列结构的祈使句来表达if引导的条件句。例如：If you set your alarm clock, you won’t oversleep.如果你上闹钟, 你就不会睡过头了。=Set your alarm clock, and you won’t oversleep.If you give him an inch, he will take a mile. 他会得寸进尺。=Give him an inch, and he will take a mile.If you don’t give him some food, he will starve.如果你不给他一点吃的, 他就会饿死。=Give him some food, or/else he will starve.语法知识精讲在阅读英文文章时, 我们有可能看到这样的句子：If you will take the trouble to read his letter carefully, you will see what he means. 如果你肯花一些时间来认真读他的信，你就会明白他是什么意思了。在if-分句中用“will＋动词原形”并不单纯表示将来意义，这里的will是个表示“意愿”的情态动词, 相当于be willing to(愿意)。要注意这种带“will＋动词原形”的if-分句在某些场合是不可以随便用的, 比如我们可以说：If he gets my letter in time, he’ll be able to change his plans. 如果他及时收到我的信, 他就能改变他的计划。却不可以说成：If he will get my letter in time, he’ll be able to change his plans.语法知识精讲be＋doing形式: 用现在进行时态表达将来，主要意义是表示按计划、安排即将发生的动作，常用于位置转移的动词, 如go、come、leave、start、arrive等, 也可用于其它动态动词。如：The president is coming to the UN this week. 总统这周将到联合国来。We are moving to a different hotel the day after tomorrow. 我们后天将换一家宾馆。在英语中, 有相当多的动态动词都可以用现在进行时表示将来。例如：Dinner is ready. We’re having fish for dinner. 晚饭好了, 今晚我们吃鱼。I’m spending my holidays in Singapore this year. 今年我要去新加坡度假。Tom isn’t finishing his high school until next year. 汤姆明年才高中毕业。1.
