Hegotan“A”thistimebecausehewentoverhislessonscarefully.2. 情态动词表示能力、义务、必要、猜测等说话人的语气和情感。情态动词只能和动词原形一起构成谓语动词。英语情态动词主要有：can, may,

15、词、副词、介词、连词、感叹词），按照一定的语法规则组合在一起，能表达一个完整意思的语言单位叫做句子。一个句子由各个功能不同的部分构成，这些部分叫做句子成分。英语句子的成分有八种：主语、谓语、宾语、表语、定语、状语、主语补足语和宾语补足语。（一）主语（subject）是句子所要说明的人或事物，是句子的主体。主语的位置通常在句首，不省略，可以担当主语的有名词、代词、数词、动词不定式、动名词和主语从句。Walls have ears.He will take you to the hospital.Three plus four equals seven.To see is to believe.S
16、moking is not allowed in public places.Whether or not they will come depends on the weather.（二）谓语动词（predicate verb）是说明主语的动作或状态的句子成分。谓语动词的位置一般在主语之后。谓语动词由实义动词或系动词担任。助动词或情态动词加其他动词的适当形式也构成谓语动词。Action speaks louder than words.The chance may never come again.Tom was very sick at heart.Mary has been workin
17、g at the dress shop since 1994.（三）表语（predicative）是用来说明主语的身份、特征和状态的。它的位置在系动词之后。可做表语的有名词、代词、形容词与分词、数词、动词不定式、介词短语、副词及表语从句等。My father is a professor.Whos that? Its me.Everything here is dear to her.The match became very exciting.The story of my life may be of help to others.Three times five is fifteen.
18、His plan is to seek work in the city.My first idea was that you should hide your feelings.（四）宾语（object）表示动作的对象，是动作的承受者。宾语一般放在及物动词之后或介词后，如果没有，则及物动词无法表示完整的动作。She covered her face with her hands.We havent seen her for a long time.Do you mind opening the window? *Give me four, please.He wants to dream a
19、 nice dream. *We need to know what others are doing.I lived in Japan in 1986.（五）定语（attribute）是修饰名词或代词的词、短语或句子。单词做定语时通常放在它所修饰的名词之前；短语和从句做定语时则放在它所修饰的名词之后。可以做定语的有名词、形容词、数词、分词及其短语、不定式、介词短语以及从句等。They are women workers.Toms father didnt write home until yesterday.Equal pay for equal work should be introdu
20、ced.The play has three acts.This is her first trip to Europe.China is a developing country.You havent kept your promise to write us often.My cat has a good nose for milk.Those who want to go to Tibet are to sign their names here.（六）状语（adverbial）是修饰动词、形容词、副词等的句子成分。状语表示地点、时间、原因、目的、结果、条件、让步、程度、方式、伴随情况等
21、。作状语的有副词、名词、介词短语、分词及其短语、动词不定式及其短语、状语从句等。These products are selling quickly.He is knee deep in snow.The best fish swim near the bottom.*She sat there doing nothing.Well send a car over to fetch you.She was slow to make up her mind.Strike while the iron is hot.There is no such a word in English so far
22、 as I know.（七）宾语补足语：我们知道，在英语中及物动词要加宾语意思才完整，不及物动词则无需加宾语。但有些及物动词，除了要有宾语之外，还要加上宾语补足语（object complement），来补充说明其身份、特征、状态或所做的动作，如果丢掉宾补，就不成为句子，或意思走样，这样的及物动词叫不完全及物动词，即只加宾语不能完全表达完整意思。这种“宾语宾语补足语”结构称为复合宾语。宾补一般跟在宾语之后。可以担当补足语的有名词、形容词、介词短语、动词不定式、分词等。They elected me captain of the team.He made me ashamed of myself
23、.We found everything there in good order.I should advise you not to miss the chance.I could feel my heart beating fast.Put your book into your schoolbag.Keep the water boiling for ten minutes.They considered Paris the brain and heart of the country.宾补出现的场合：1. 在表示心理状态的动词后做宾补，如：consider, think, believ
24、e, discover, find, imagine, judge, suppose, prove等。结构：to be + 形容词或名词。think, consider, find后的to be常可省略。 We consider him (to be) a good teacher. He proved that theory (to be) very important. I thought her (to be) nice and honest the first time I met her.2. 使役动词make, have, leave后面。 The heavy rain made
25、it impossible for us to go out. What make the grass grow? They had us laughing all through the meals. Ive had my radio repaired so soon because my father had me do it. Leave the door open when you go out. They walked off and left me sitting there alone.3. 感官动词hear, feel, listen to, look at, watch, n
26、otice, observe, smell等后面，若接不定式做宾补，要把to去掉，但在被动语态中to要加上。 I saw him drive the car at high speed yesterday. Ive never heard the song sung. Do you smell something burning?4. 表示情感状态的词后面，如：love, like, prefer, hate, want, wish, expect等。 Id prefer you to leave him alone. I dont want there to be any trouble.注
27、意： 在完整的句子中，如果谓语动词是不完全及物动词，而后面接的宾语是短语或从句，后再接宾语补语时，必须将作宾语的短语或从句放在宾语补语之后，把it放在它的原来位置,这时it是形式宾语,短语或从句是真正宾语。I think it wrong to tell lies. 我认为撒谎是错误的。it是形式宾语，不定式短语to tell lies是真正宾语,wrong是宾语补语。Did you make it clear why she didnt come? 你弄清楚她没有来的原因了吗?（八）主语补足语（subject complement）是对主语的补充，如果把宾语补足语所在的结构变成被动语态，原宾
28、语成为主语，原宾语补足语相应地变为主语补足语。可以担当补足语的有名词、形容词、介词短语、动词不定式、分词等。I was elected captain of the team.The water was kept boiling for ten minutes.Everything there was found in good order.Some goods are left unsold. The boy was made to work hard 10 hours a day.但还有一类主补不是出现在被动语态的句子中。英语有一定数量的不及物动词，完全保留了本身的词汇意义，同时又发挥着系
29、动词的功能。它们与主语补足成分连用，所以这类词被称为“准系动词”。用于“S+Vi+Cs”(S代表主语，Vi代表不及物动词，Cs代表主语补足语)这一句式的动词都属于这种用法。有时，主语补足语不紧跟系动词，有可能被其它状语成分隔开。He left home a poor worker ten years ago and came back a rich business man.His father died young.The morning dawned fresh and clear after the storm at night.We parted the best friends.词类
30、与句子成分的关系： 词类与句子成分既有区别又有联系。词类是孤立地单词分类；而句子成分则指单词、词组、短语或从句在句中的作用。句子的各种成分总是由属于一定词类的单词或词组、短语、从句来担当的。因此在词类和句子成分之间存在着某种对应关系。主语谓语宾语表语定语状语宾（主）补足语动词名词代词形容词副词数词不定式分词动名词介词短语三、基本句型所谓基本句型(basic sentence pattern)就是集中基本的谓语结构的格局。千变万化的句型都是由他们演变而来的。英语的基本句型有五种。主-谓 S-V主-谓-宾 S-V-O主-系-表 S-linkV-P主-谓-间宾-直宾 S-V-IO-DO主-谓-宾-宾补 S-V-O-C （一）主-谓 S-V此句型句子共同特点：句子的谓语动词都能表达完整的意思，所以都是不及物动词，后面常跟副词、介词短语、状语从句等做状语。SV（不及物动词）Timeflies.The moonrose.Th
