11、”.)l)在形容词或副词的比较级前，m)可以用“a little, even, far, much,still”的等词语来修饰，n)以加强语气。o)表示“越来越.”时，p)常用“形容词或副词的比较级+and+形容词或副词的比较级”结构，q)但要注意，r)对于多音节与部分双音节形容词，s)副词而t)言，u)若要表达此意时，v)要用“more and more+形容词或副词的原级“结构。w)在表示“其中最.之一“的含义时，x)常使用 “one of+the+形容词最高级形式+名y)词复z)数”结构，aa)其中的定冠词the不bb)可以省略。cc)如果强调“两者中比较的(一个)”的意思时，dd)可使

12、用“the+形容词比较级+其它”结构。ee)表示“越.越.”, 可使用“the+形容词或副词的比较级，ff)the+形容词或副词的比较级”结构。2 .一般将来时一般将来时的构成：由助动词shall或will加动词原形构成，shall用于第一人称。在口语中，will在名词或代词后常简略为ll， will not常简略为wont。这个时态的肯定，否定与疑问结构可表示如下：肯定句否定句疑问句I (We)shall(will) go.You(He, She, They) will go.I(We)shall(will) not go.You(He, She, They)will not go.Shal

13、l I(we) go?Will you (he, she, they) go?用”be going to +动词原形”也可表示将来时，表示将要发生的事，打算或决定要做的事。b)一般将来时的用法：1)表示将要发生的动作或情况;2) 不以人的意志为转移，肯定要发生的事情。The day after tomorrow will be National Day.后天是国庆日。3. in/after:in是指以现在时间为起点的“在一段时间以后”。也可以表示“在将来多少时间之内”，句子中的谓语动词要用一般将来时态;after常指以过去时间为起点的“一段时间之后”，所以它及过去时态连用。当after指某个特

14、定的未来时刻或日期之后，或指以将来某一时间为起点的若干时间之后时，它可以及将来时态连用。4.more, less, fewer的用法区别：more为many, much的比较级，意为“更多”，可修饰可数及不可数名词。Less是little的比较级，意为“更好，较少”，修饰不可数名词。Fewer是few的比较级，意为“更少”，修饰可数名词复数。【注意】few, little表示否定“几乎没有”。a few, a little表示肯定“一点，几个”。5.would like sth意思为“想要某物“; would like to do意思为”想要做某事“。回答would like句型的一般疑问句时

15、，其肯定回答为 “Yes, please.”;否定回答“No, thanks”或 “Id like /love to, but.”6. Such作形容词，意思是“如此的”“这样的”，修饰各种名词。Such这样的。如It is such bad weather.天气如此恶劣。Such常与as搭配，表示一种类别。如We enjoy such a voice as hers.我们喜欢象她那样的嗓子。Such常与表示结果的that从句搭配，表示“如此.以至于”如It was such a hot day that we all had to stay at home.Suchthat与sothat都可

16、用来引出一个结果状语从句。由于such是形容词，所以that从句前有一个受such修饰的名词;而so 是副词，用以修饰形容词或副词，因此that从句前一般不出现名词。如They are such kind-hearted teachers that people in the village all respect them.The exam was so difficult that many students failed to pass it.如果名词是可数名词的单数形式，such与so的位置不同：such+a/an+形容词+单数名词so+形容词+a/an+单数名词如果名词是不可数名词或

17、名词复数，只可用such,不能用so.:such+形容词+不可数名词或复数名词如果被修饰的不可数名词被much, little, 或复数名词被many, few等表示量的形容词修饰时，用so，不用such.当little表示“年纪小的”时，可用such+little+名词。7.be able to 为“能，会”，表示能力，在这个意义上及can的意思相同，一般情况下两者可以互换，但can只有现在式与过去式(could)而be able to则用于更多的时态，主要表达在be的变化。两者在用法上有一些差异：can (could)表示主观能力不表示意愿，它的将来时用will be able to而 b

18、e able to表示主观意愿强调克服困难做某事。【重点语法】一般将来时表示将要发生的动作或存在的状态。本时态标志词：1.含tomorrow; next短语; 2.in+段时间 ; 3.how soon;4.by+将来时间; 5.by the time sb.do 6.祈使句句型中：or/and sb. will do例Be quick, or you will be late=If you dont be quick, you will be late7.在时间/条件状语从句中, 如果从句用一般现在时, 主句用将来时 8.another day比较be going to 及will:be g

19、oing to 表示近期、眼下就要发生的事情，will 表示的将来时间则较远一些。如： He is going to write a letter tonight. He will write a book one day.2. be going to 表示根据主观判断将来肯定发生的事情，will表示客观上将来势必发生的事情。He is seriously ill. He is going to die. He will be twenty years old.3. be going to 含有“计划，准备”的意思，而 will 则没有这个意思，如：She is going to lend u

20、s her book. He will be here in half an hour.4.在有条件从句的主句中，一般不用 be going to, 而多用will, 如：If any beasts comes at you, I'll stay with you and help you.掌握了它们的这些不同，你就能很好的区分be going to及will了。be going to do (动词原形)结构：表示打算、准备做的事情或者肯定要发生的事情。如：It is going to rain.will do 结构表示将来的用法：1. 表示预见Do you think it will

21、 rain?You will feel better after a good rest.2. 表示意图I will borrow a book from our school library tomorrow.What will she do tomorrow?基本构成如下：一般疑问句构成：(1)will+主语+do? Will Sarah come to visit me next Sunday?(2)there be 结构的一般疑问句：Will there + be ?Will there be fewer trees? Yes, there will. / No, there wont

22、否定句构成：will + not (wont)+doSarah wont come to visit me next Sunday.特殊疑问句构成：特殊疑问词+will+主语+?What will Sarah do next Sunday?根据例句，用will改写下列各句例：I dont feel well today. (be better tomorrow) Ill be better tomorrow.1. Gina has six classes today. (have a lot of homework tonight)_2. Im tired now. (sleep later)

23、_3. My parents need a new car. (buy one soon)_4. We cant leave right now. (leave a little later)_5. The weather is awful today. (be better tomorrow)_答案：1. Shell have a lot of homework tonight. 2. Ill sleep later. 3. Theyll buy one soon.4. Well leave a little later.5. Maybe itll be better tomorrow.第二
