英文語(yǔ)法入門
動(dòng)詞的英語(yǔ)語(yǔ)法基礎(chǔ)知識(shí)，我們來(lái)看一看動(dòng)詞的語(yǔ)法是怎么樣的吧。下面是學(xué)習(xí)啦小編給大家整理的英文語(yǔ)法入門，供大家參閱!
英文語(yǔ)法入門：第一人稱用will還是shall
A、在前面的章節(jié)中，will專用來(lái)表示意圖：
I will wait for you.相當(dāng)于：
I intend to wait for you.
我會(huì)等你。
在不存在任何意圖的場(chǎng)合用shall，即shall用于不牽涉到主語(yǔ)愿望的動(dòng)作：
I shall be 25 next week.
下星期我就25歲了。
We shall know the result next week.
下周我們就會(huì)知道結(jié)果了。(因?yàn)榻Y(jié)果將在報(bào)紙上公布。)
Unless the taxi comes soon we shall miss our plane.
出租汽車要是不快點(diǎn)來(lái)，我們就要誤飛機(jī)了。
I'm sure I shan't lose my way.
我肯定不會(huì)迷路的。
I shall see Tom tomorrow.
明天我會(huì)見到湯姆的。(也許我們坐同一列火車上班。)
現(xiàn)在，shall的以上用法在較正式的英語(yǔ)中仍可見到，但在口語(yǔ)中已不再常見了。相反，通常用will：
I will be 25 next week.
下星期我25歲了。
We'll know the result tomorrow.
明天我們就會(huì)知道結(jié)果了。”
Unless the taxi comes soon we'll miss the plane.
出租汽車要是不快點(diǎn)來(lái)的話，我們就要誤飛機(jī)了。
I'm sure I won't lose my way.
我肯定不會(huì)迷路的。
但是，有時(shí)will可能改變句子的意思。如果在 I shall see Tom tomorrow這個(gè)句子中用 will代替 shall，就會(huì)變成 I will see Tom tomorrow。這個(gè)句子可能表示明天我要見湯姆的意圖。為避免這種模棱兩可的情況就用將來(lái)進(jìn)行時(shí)：
I'll be seeing Tom tomorrow.
明天我會(huì)見湯姆。
然而，shall在疑問(wèn)句中仍可使用。
shall常用在let's后面的附加疑問(wèn)中：
Let's go，shall we?
咱們走，好嗎?
用于建議：
Shall we take a taxi?
我們乘出租汽車，好嗎?
用于請(qǐng)求對(duì)方下命令或作指示：
What shall I do with your mail?
我應(yīng)該怎么處理您的信件?
用于推測(cè)：
Where shall we be this time next year?
明年的這個(gè)時(shí)候我們會(huì)在什么地方?(雖然這里也可以用will。)
B、shall表示決心
在前面已經(jīng)講到，通常是由will表示決心。但是，人們有時(shí)感到為了表示決心應(yīng)當(dāng)用另外一個(gè)“較重的”、通常不大用的詞，因此就用shall：
(in a speech)We shall fight and we shall win.
(在演說(shuō)中)我們決心戰(zhàn)斗，我們定會(huì)贏得勝利。
We will fight and we shall win也一樣可用。
有時(shí)shall這樣用表示許諾，就像第二人稱shall所表示的那樣：
You shall have a sweet.
你會(huì)吃到一塊糖。相當(dāng)于：
I promise you a sweet.
我答應(yīng)給你一塊糖。
We shall win這個(gè)句子中，說(shuō)話人在保證能取得勝利。shall在日常會(huì)話中可以這樣用：
I shall be there，I promise you.
我會(huì)在那里的，我向你保證。
但這里will也一樣可用，對(duì)學(xué)生來(lái)說(shuō)用will可減少麻煩。在對(duì)于究竟應(yīng)當(dāng)用shall還是用will存有疑問(wèn)的時(shí)候要用will。
