三. 具体内容
1. Using indefinite pronouns/adverbs
当说话人表示请求，建议或反对等，带有肯定意图时，不管句子形式如何都可用some系列词。
eg.
Why don’t you read something interesting? 　你为什么不看一些有趣的东西？
Would you like something to drink? 要喝点什么？
Is there something to eat? 有什么东西吃吗？
Is there anything to eat? （I am hungry, Do you have any…?） 你没有什么东西吃？
当anyone, anybody表“任何人”，anything表“任何事”的含义时，也可用于肯定句。
eg.
Anyone / Anybody can do it. 任何人都可做这件事。
He is cleverer than anyone else in his class. 在班上他比任何别人都聪明。
2. The verb take and bring
take 和bring的区别：take指从这里拿起、拿走，即把某人或某物从说话人处带到别处，包含有away的含义。
eg.
Could you help me to take the box to the classroom? 你能帮我将这个盒子拿到教室吗？
I’ll take you to see our teacher. 我将带你去见老师。
It’s going to rain, please take an umbrella with you. 要下雨了，请随身带把伞。
bring指从别处拿到这里来，或指拿到说话人和听话人都要去的地方。
eg.
Bring me a cup of tea, please. 请给我拿杯茶。
Please bring the CD to school tomorrow. 请明天把那张CD带到学校。
2. 表“携带，运送”之意的词还有get和 carry。
get意为“拿，取”，是指从说话人所在地出发，到达别处后，把某人某物带回原处，表示的动作是一个来回。
eg.
Please get a doctor at once. Bill is having a high fever. 请立刻请医生来，比尔正发高烧。 carry 表车、船、牛、马等载人或物，也可表人用手提，用肩扛，用背背。强调动作的
移动性，不强调方向性。

eg.
Let me help you carry the heavy box.! 让我帮你搬那个重盒子吧！
3. 句型“Shall I /we…？”意思是“要我／我们…吗？”，“我／我们要不要…？”。情态动词shall用于第一人称疑问句表示征求对方意见或向对方提出建议。例如：
Shall I get you some more tea? 要不要我给你加点茶？
Shall I turn on the light? 要不要开灯？
Shall I go instead of you?（=Shall I go for you?）我替你去好吗？
Shall we go for a walk?（=Let’s go for a walk, shall we?）我们去散散步好吗？
Shall we go to see a film? 我们去看电影好吗？
Shall we go to our lesson? 我们开始上课好吗？
4. We are alone here. We’re all by ourselves. 我们独自在这儿，孤独无助。
all by oneself=alone 表示“独立地，单独地”，相当于alone，在句子中做状语。
Can you do it all by yourself ?   你能独立做这件事吗？
He learned English all by himself. 他是自学的英语。 
5. The picnic basket was no longer under the tree. 野餐篮子已经不在树下了。
no longer = not ... any longer / not ... any more.
表示“不再”的意思。一般修饰延续性动词，表示动作或状态不再继续。在句子中，它放在实义动词之前，或情态动词，助动词和be动词之后。如：
She no longer works there.=She doesn’t work there any longer. 她不再在那儿工作了。
He’s no longer a student = He’s not a student any longer. 他不再是学生了。
They no longer felt afraid = They didn’t feel afraid any longer. 他们不再感到害怕了。
6. Sooner or later you’ll find it somewhere. 迟早你会在某个地方找到它的。
（1）sooner or later意为“迟早，早晚”，常用于将来时，在句子中做状语。如：
You should tell her, because she’ll find out sooner or later.
还是告诉她吧，因为她迟早会发觉的。
You’ll be sorry for what you said and did sooner or later.
你早晚会为你所说的和所作的后悔。
If you drive like that, you’ll have an accident sooner or later.
如果你那样开车的话，迟早你会出事的。
somewhere意为“某处，在某处”，是不定副词，常用的不定副词还有：nowhere, everywhere, anywhere. 如：
I can’t find it anywhere. 我到处都找不到它。
I’ve looked everywhere. 我到处都看过了。
—Where are you going at the weekend? 周末打算去哪？
　 —Nowhere special. 无处可去。
7. It’s too heavy to carry. 这个太重了，（我们）拿不动。
（1）too…to…意思为 太…以至于不能…。句型结构为too+形容词／副词+to+动词原形，该句型用于肯定句，但表达否定的意思，如：
He is too excited to speak. 他太激动了，说不出话来。
It’s too cold to go in the sea yet. 天太冷还不能下海。 
（2）如在too前有否定词，则整个句子用否定词表达肯定，too 后那个词表达一种委婉含义，意为“不太”。
It’s never too late to mend.（谚语）改过不嫌晚。
（3）当too 前面有only, all, but时，意思是：非常… 等于very。
I’m only too pleased to be able to help you. 我非常高兴能帮助你。
He was but too eager to get home. 他非常想回家。
（4）在too…to这一结构中，如果主语和不定式的宾语是一致的，则不要重复。如：
［误］This box is too heavy to lift it.
［正］This box is too heavy to lift.
［误］The child is too young not to go to school.
［正］The child is too young to go to school.
