系動詞是什么？
系動詞
系動詞
系動詞（Linking Verb）是一種用于連接主語和表語的動詞，主要用來表示主語的狀態(tài)、性質(zhì)、特征或身份，而不是描述動作。常見的系動詞有：表感官（feel，look，smell，sound，taste），表似乎（seem，appear），表變化詞（get，become，turn，grow，make，come，go，fall，run），表保持（remain，keep，stay，continue，stand，rest，lie，hold）
Be 動詞：
“Be”除了原形的“be”之外,還有另外七種形式：
am（第一人稱單數(shù)形式），
is（第三人稱單數(shù)形式），
are（第二人稱單數(shù)和復(fù)數(shù)形式），
been（過去分詞），
being,（現(xiàn)在分詞），
was（第一人稱與第三人稱單數(shù)過去式），
were（第二人稱單數(shù)和復(fù)數(shù)過去式）.
實義動詞是什么？
實義動詞
實義動詞
實義動詞：是表示具體動作、行為或狀態(tài)的動詞，具有實際意義，可以單獨作謂語。實義動詞通常描述主語做了什么或發(fā)生了什么。
實義動詞分為及物動詞和不及物動詞：
及物動詞 ：需接賓語才能完整表達意義，否則句子不完整。
She bought a book.（她買了一本書。）
→ "a book" 是賓語
不及物動詞 ：本身意義完整，無需賓語。
The baby cried.（嬰兒哭了。）→ 沒有賓語
但有些不及物動詞與介詞連用后接賓語。
部分實義動詞可兼作及物和不及物：
①.The post office closes at 9:00 p. m．
②.Close the window, please．
助動詞是什么？
助動詞
助動詞
助動詞：協(xié)助主要動詞構(gòu)成謂語的詞叫助動詞 。 助動詞不能單獨作謂語，本身沒有詞義，在句中只能與主要動詞（實義動詞和系動詞）搭配構(gòu)成謂語，并構(gòu)成時態(tài)、語態(tài)、語氣以及問句、否定句和強調(diào)句等形式。
基本助動詞：be, do, have
She is singing.（她正在唱歌。）→ 構(gòu)成進行時
情態(tài)助動詞: can, could, may, might, must, shall… 有詞義
You must study hard.（你必須努力學習。）→ 表義務(wù)
半助動詞: be going to, be about to, used to, have to, had better
I am going to visit my parents.（我打算去看望父母。）→ 表將來計劃
不能單獨作謂語
（必須+主動詞）
情態(tài)動詞是什么？
情態(tài)動詞
情態(tài)動詞
不能單獨作謂語
（必須+主動詞）
情態(tài)動詞（Modal verb），本身有一定的詞義，表示語氣的單詞。但是情態(tài)動詞不能獨立作謂語，只能和動詞原形一起構(gòu)成謂語。情態(tài)動詞用在行為動詞前，表示說話人對這一動作或狀態(tài)的看法或主觀設(shè)想。
情態(tài)動詞(Modal verbs)：表示說話人的某種語氣或者情緒，如可能，意愿，猜測，義務(wù)，需要等。
1. 基本特征：
(1)情態(tài)動詞不能單獨做謂語，后面接動詞原形；
She must go now.（正確） She must to go now.（錯誤，不加to）
(2)情態(tài)動詞 沒有人稱和數(shù)的變化 （be able to，have to除外）
He can swim.
(3)其否定形式在后面直接加not
You can’t swim.（你不會游泳。）
情態(tài)動詞：Modal verbs
情態(tài)動詞的用法：be able to
be able to：
后接動詞原形，表示某人做某事的能力，可用于大多數(shù)時態(tài)。用于過去時態(tài)時，還可以表示“某人過去或當時成功地做了某事”。例如：
a. I will be able to speak Japanese in another few months.
（再過幾個月，我就能講日語了。）
b. They were able to escape from the building when the fire broke out.
（火災(zāi)發(fā)生時，他們設(shè)法從那棟建筑里逃了出去。）
情態(tài)動詞的用法：be able to
can（天生能力） vs. be able to（后天努力實現(xiàn)）
1.can只有現(xiàn)在時和過去時(could)，而be able to則有更多的時態(tài)變化。
2.can一般指自身具有的能力，而be able to則表示經(jīng)過一段時間的努力后所具有的能力，相當于manage to do或succeed in doing。
can 描述"常態(tài)能力"（泛泛而談）：
1.Dolphins can swim fast.（海豚天生游得快）
be able to 強調(diào)"具體實現(xiàn)"（尤其是經(jīng)過努力后）：
2.After 6 months of training, I was able to run a marathon.
（經(jīng)過6個月訓練，我終于能跑馬拉松了→強調(diào)結(jié)果）

2. dare作實義動詞，譯為“敢于”，通常為“dare to do sth” (有人稱與時態(tài)的變化）

2. 以need 開頭的疑問句，肯定回答用must, 否定回答可用needn’t。

Need I finish the work today —Yes, you must /No, you needn’t
Must I ask for her permission — Yes, you must /No，you needn’t/don’t have to
情態(tài)動詞的用法：need
3.need用作實義動詞， (有時態(tài)與人稱的變化)。
否定式和疑問式要借助助動詞do/does/did。
need 作實義動詞時常用于下列句式： need + to do / need + 名詞
need doing = need to be done（表示被動意義）

Lily needed more money to pay for that book at that time. (人稱數(shù)的變化)
Lily doesn’t need any more money to pay for that book. (否定，添加助動詞)
The car needs washing. = The car needs to be washed. （車需要洗了。）
情態(tài)動詞的用法：have to
have to 的含義與must相似，兩者往往可以互換使用，但have to 有各種時態(tài)，且強調(diào)客觀需要（如規(guī)則、法律、外部壓力等），意為 “不得不”。
must表示“必須”(側(cè)重于主觀意愿); mustn’t表示“禁止”。

I have to leave because of the bad weather.
（因為天氣不好，我不得不離開了。）

如果你不想去，就不必去。

had better:后接動詞原形，意為“最好”，主要用來表示勸告或建議。用于現(xiàn)在時或?qū)頃r，可用于一切人稱，沒有任何詞形變化。
