高一英語(yǔ)必修一知識(shí)點(diǎn)語(yǔ)法
英語(yǔ)語(yǔ)法的學(xué)習(xí)是英語(yǔ)語(yǔ)言學(xué)習(xí)的基礎(chǔ),語(yǔ)法一直是高中英語(yǔ)教學(xué)的一個(gè)難點(diǎn),那么高一必修一的英語(yǔ)你掌握了多少了呢?接下來(lái)學(xué)習(xí)啦小編為你整理了高一英語(yǔ)必修一知識(shí)點(diǎn)語(yǔ)法,一起來(lái)看看吧。
高一英語(yǔ)必修一知識(shí)點(diǎn)語(yǔ)法:able用法
1. 表示“有能力的”、“能干的”,可用作表語(yǔ)或定語(yǔ)。如:
He is an able manager. 他是位有能力的經(jīng)理。
He is old but still able. 他雖年老,但仍有很能干。
2. 用于 be able to do sth(能或會(huì)做做某事)。如:
He is able to speak English. 他會(huì)說(shuō)英語(yǔ)。
Everyone here is able to type. 這兒的每一個(gè)人都會(huì)打字。
He will be able to get about in a week or two. 再過(guò)一兩個(gè)星期左右他就能走動(dòng)了。
He studied hard and was able to pass his examinations. 他學(xué)習(xí)很努力,所以考試及了格。
注:be able to 不僅有多種時(shí)態(tài)形式(通常不用于進(jìn)行時(shí)或與 be going to 連用),而且還可以與某些情態(tài)動(dòng)詞連用(通常不與 can 連用),甚至還可以有非謂語(yǔ)形式。如:
Since his accident he hasn’t been able to leave the house. 自出事之后,他一直未能離開(kāi)家。
You might be able to persuade him. 你也許能夠說(shuō)服他。
I hope to be able to do the work. 我希望能干得了這項(xiàng)工作。
I regret not being able to help her. 我很遺憾未能幫助她。
3. able 的比較級(jí)和最高級(jí)通常是 abler 和 ablest,也可以是 more able 和 most able,有時(shí)還可用 betterable和best able。如:
You are better able to do it than I (am). 你比我更有能力做這件事。
She’s the person best able to cope. 她是個(gè)最能妥善處理問(wèn)題的人。
4. 若要加強(qiáng)語(yǔ)氣,其前除可very, quite, perfectly等修飾外,有時(shí)還可用well修飾。如:
He is quite [well] able to take care of himself. 他完全有能力照顧自己。
He’s a very able student; he’s just too lazy. 他是個(gè)很有能力的學(xué)生,只是太懶了。
若受just, only just修飾,則表示“只能”“僅能”。如:
I was just able to make out a dark figure in the distance. 我只能看見(jiàn)遠(yuǎn)處有個(gè)黑影。
5. able的反義詞是unable(不能的,不會(huì)的),不是disable,后者是動(dòng)詞,其意為“使殘廢”“使無(wú)能力”。比較:
They were unable to reach a decision. 他們沒(méi)法做出決定。
Now that he was disabled, his house had become a prison to him. 因?yàn)樗麣垙U了,他的房子就成了他的牢籠。
高一英語(yǔ)必修一知識(shí)點(diǎn)語(yǔ)法:admit用法
一、表示“承認(rèn)”
1. admit一般為及物動(dòng)詞,直接跟賓語(yǔ);表示向某人承認(rèn)用介詞 to。如: He admitted his mistake. 他承認(rèn)了他的錯(cuò)誤。
He admitted to the teacher that he was wrong. 他向老師承認(rèn)他錯(cuò)了。 This meant admitting defeat. 這就意味著承認(rèn)失敗了。 但有時(shí)也用作不及物動(dòng)詞,此時(shí)一般后接介詞to。如:
He admitted to the murder. 他供認(rèn)了謀殺罪。
He admitted to having taken the money. 他承認(rèn)拿了那筆錢。
由于 admit 表示“承認(rèn)”可用作及物動(dòng)詞或不及物動(dòng)詞,所以上面各例中的介詞 to 有時(shí)也可省略。
2. admit
She admitted having read the letter. 她承認(rèn)讀過(guò)這封信。
I admit breaking the window. 我承認(rèn)打破了窗子。
3. admit可后接帶不定式的復(fù)合賓語(yǔ),但其中的不定式通常應(yīng)是 to be。如: They admitted him to be mad. 他們承認(rèn)他瘋了。
You must admit the task to be difficult. 你們得承認(rèn)任務(wù)是艱巨的。 偶爾接其它形式的復(fù)合賓語(yǔ)。如:
He admitted himself a failure. 他承認(rèn)失敗。
He admitted himself beaten. 他承認(rèn)輸了。
4. 有時(shí)用于插入語(yǔ)中。如:
This, I admit, was wrong. 我承認(rèn)這錯(cuò)了。
二、表示“允許進(jìn)入”“使能進(jìn)入”
1. admit通常只用作及物動(dòng)詞。如:
This ticket admits one person only. 此券只準(zhǔn)一人入場(chǎng)。
There were no windows to admit air. 沒(méi)有窗子可使空氣流入。 可用于引申義,表示允許進(jìn)入某一組織、機(jī)構(gòu)、學(xué)校、團(tuán)體等。如: They admitted him to [into] their organization. 他們接受他參加了他們的組織。 How many students have been admitted into the school this year? 今年這所學(xué)校有多少學(xué)生入學(xué)?
試比較 (注意介詞不同):
He was admitted to [into] the Party. 他被吸收入黨。
He was admitted as a Party member. 他被接納為黨員。
2. 往往含有動(dòng)態(tài)意味,所以一般不與 enter, go in 之類的詞連用。如:
他打開(kāi)門讓我進(jìn)了屋。
正:He opened the door and admitted me into the house.
誤:He opened the door and admitted me to enter into the house.
三、用于 admit of
admit of為習(xí)語(yǔ),意為“容許”“有……的可能”“有……的余地”(此時(shí)句子主語(yǔ)通常是物而不是人)。如:
The matter admits of no delay. 這事刻不容緩。
The word admits of no other meaning in the case. 這個(gè)詞在此例中不可能有別的意思。
四、兩個(gè)派生詞的用法
1. admission n. 進(jìn)入,入場(chǎng) (不可數(shù));承認(rèn) (可數(shù),但通常只用作單數(shù))。如: No admission without tickets. 無(wú)票不準(zhǔn)進(jìn)入。
Admission to [into] the school is by examination only. 進(jìn)入該校學(xué)習(xí)必須通過(guò)考試。 He made an admission that he was a thief. 他供認(rèn)他是小偷。
2. admittance n. 進(jìn)入 (不可數(shù))。有時(shí)可與 admission 互換,但不如 admission 常用。
