原句回放1:
I began as a calculating machine in France in 1642.
1642年我在法國(guó)誕生時(shí)不過(guò)是一臺(tái)計(jì)算機(jī)器。
句子中的calculating是動(dòng)名詞作定語(yǔ)的用法,動(dòng)名詞作定語(yǔ)一般表示用途,例如:
a walking stick拐杖
a swimming pool游泳池
a washing machine洗衣機(jī)
注意動(dòng)名詞和現(xiàn)在分詞作定語(yǔ)的不同,現(xiàn)在分詞作定語(yǔ)往往表示動(dòng)作或特征,例如:
a sleeping boy一個(gè)正在睡覺(jué)的男孩
exciting news令人激動(dòng)的消息

原句回放2:
Although I was young I could simplify difficult sums.
雖然我問(wèn)世時(shí)間不長(zhǎng),但我能使復(fù)雜的計(jì)算簡(jiǎn)單化。

Ⅰ.相同點(diǎn):①在although和though引導(dǎo)的讓步狀語(yǔ)從句中,主句里不可用but,若要強(qiáng)調(diào)前后兩部分的對(duì)比意義,可在主句前加yet或still。
e.g.Although/Though he has a lot of money,yet/still he is unhappy.
他雖然有很多錢,但并不幸福。
②although和though引導(dǎo)讓步狀語(yǔ)從句時(shí),常采用省略形式。
e.g.Although tired(=Although he was tired),he kept on working.
雖然很疲勞,但他繼續(xù)工作。
The problem,though complicated(=though it is complicated),can be solved without much difficulty.

Ⅱ.不同點(diǎn):although和though同義,在一般情況下,可以互換使用。只是though較普遍,常用于非正式的口語(yǔ)或書(shū)面語(yǔ)中,而although則較為正式,另外although語(yǔ)氣比though重,常用以強(qiáng)調(diào)讓步概念
e.g.Though/Although my car is very old,I don't want to buy a new one.
雖然我的汽車很舊,但我不想買一輛新的。
He insisted on doing it although I warned him not to.
雖然我警告他不要做,但他仍然堅(jiān)持要做。

Ⅲ.當(dāng)讓步狀語(yǔ)從句指某種假設(shè)情況時(shí),
通常用though,而不用although。
e.g.Though all the world were against me,I should still hold to my opinion.
就算全世界都反對(duì)我,我還是堅(jiān)持我的立場(chǎng)。

Ⅳ.①.though可以獨(dú)立用作副詞,常放在句末,
意為all the same(還是;仍然)或however(可是;然而),而although無(wú)此用法。
e.g.She didn't tell me what she had done,but I know it,though.
她沒(méi)有告訴我她所做的事情,但我還是知道了。
It's hard work.I enjoy it,though.
工作很苦,可是我喜歡。
②.though引導(dǎo)讓步狀語(yǔ)從句時(shí)可以倒裝,而although從句則不能。
e.g.Bravely though they fought,they had no chance of winning.
雖然他們打得很勇敢,但還是沒(méi)有機(jī)會(huì)獲勝。

原句回放3:
At that time it was considered a technological revolution and the start of my “artificial intelligence”.
當(dāng)時(shí),人們把這看成是一場(chǎng)技術(shù)革命和人工智能的開(kāi)端。
1)technological revolution意為“技術(shù)革命”
2)artificial intelligence意為“人工智能”
3)artificial adj.人造的;假設(shè)的;矯揉造作的
The room was decorated with artificial flower.
房間是用人造花裝飾的。
4)inteligence n.智力;聰明;智能
He's a man of very high intelligence.
他是個(gè)非常聰明的人。

原句回放4:
In 1936 my real father,Alan Turing,wrote a book about how I could be made to work as a “universal machine”to solve any difficult mathematical problem.
在1936年,我真正的父親,艾倫圖靈寫了一本書(shū),講述了怎樣能使我成為一臺(tái)“通用機(jī)器”來(lái)解決任何難以解決的數(shù)學(xué)問(wèn)題。
句子中的how I could be made to work as a “universal machine”to solve any difficult mathematical problem是介詞about的賓語(yǔ)從句

原句回放5:
By the 1940s I had grown as large as a room.
到了20世紀(jì)40年代的時(shí)候,我已經(jīng)大得像間房子。
1)the 1940s意為“20世紀(jì)40年代”
注意:定冠詞the不可以省掉。另外,表示年代的s也必須帶上。
2)by the 1940s常常和過(guò)去完成時(shí)連用。

原句回放6:
As time went by,I was made smaller.
在本句中,as用作連詞,引導(dǎo)時(shí)間狀語(yǔ)從句,表示“隨著…”,
表示“隨著……”時(shí),也可以用with,但with是介詞,后面一般不接句子。

此內(nèi)容正在抓緊時(shí)間編輯中,請(qǐng)耐心等待
