課文詳注 Further notes on the text
1．He is working for a big firm and he has already visited a great number of different places in Australia. （他）正在為一家大公司工作，并且已經(jīng)去過(guò)澳大利亞的不少地方了。
（1） work for指“在……上班／任職”：
表達(dá)“上班”這個(gè)意思時(shí)還可以說(shuō)work at：
She works at a department store.
她在一家百貨商店上班。
（2）a number of只能接可數(shù)名詞的復(fù)數(shù)形式。通常，number前有g(shù)reat, large, good, small, certain等形容詞，數(shù)量大小也隨之改變：
A large/ great number of our students are Danish.
我們的學(xué)生中有許多是丹麥人。
There are a small number of spelling mistakes in your homework.
你的家庭作業(yè)里有少數(shù)幾個(gè)拼寫錯(cuò)誤。
2．He will soon visit Darwin. 他不久還將到達(dá)爾文去。
will 表示將來(lái)要發(fā)生的事。這句話的時(shí)態(tài)是一般將來(lái)時(shí)。（cf. 第12課語(yǔ)法）下一句話From there, he will fly to Perth也是一般將來(lái)時(shí)。
3．My brother has never been abroad before, so he is finding this trip very exciting. 我弟弟以前從未出過(guò)國(guó)，因此，他覺得這次旅行非常激動(dòng)人心。
（1）這句話由兩個(gè)簡(jiǎn)單句組成，后一句由連詞so引導(dǎo)，為表示結(jié)果的狀語(yǔ)從句。
（2）find作“發(fā)現(xiàn)”、“發(fā)覺”講時(shí)賓語(yǔ)往往帶補(bǔ)足語(yǔ)（一般為形容詞），說(shuō)明賓語(yǔ)的狀況、性質(zhì)等：
I find the film very interesting.
我覺得這電影很有趣。
She found Ton's room very dirty.
她發(fā)現(xiàn)湯姆的房間非常臟。
She has already found herself wrong.
她已經(jīng)發(fā)現(xiàn)自己錯(cuò)了。
需要注意的是，find一詞很少用于進(jìn)行時(shí)態(tài)，一般用于過(guò)去時(shí)、完成時(shí)及一般現(xiàn)在時(shí)等。
語(yǔ)法 Grammar in use
1．現(xiàn)在完成時(shí)與現(xiàn)在進(jìn)行時(shí)
現(xiàn)在完成時(shí)的時(shí)間概念有時(shí)是不確定的。（cf. 第1冊(cè)第83～88課）我們所關(guān)心的是現(xiàn)存的結(jié)果，或者過(guò)去發(fā)生的事對(duì)現(xiàn)在的影響。現(xiàn)在完成時(shí)不能和明確表示過(guò)去的副詞（如ago, yesterday等）連用。經(jīng)常和現(xiàn)在完成時(shí)連用的副詞和副詞短語(yǔ)有：before（now）（〈在此〉以前）；so far（到目前為止）；up to now （直到現(xiàn)在）；just（剛剛）；already（已經(jīng)）；lately（近）；now（現(xiàn)在）；疑問(wèn)句和否定句中常用ever, yet, never, not… ever等?，F(xiàn)在進(jìn)行時(shí)經(jīng)常用于表示在短期內(nèi)正在進(jìn)行的動(dòng)作或存在的情況，因此往往不需要和時(shí)間狀語(yǔ)連用。試比較：
2．同位語(yǔ) (Appositives)
一個(gè)名詞（或短語(yǔ)等）與另一個(gè)名詞（或短語(yǔ)）并列而作為其說(shuō)明或限定成分時(shí)稱為同位語(yǔ)。同位語(yǔ)與它所補(bǔ)充說(shuō)明的成分之間用逗號(hào)隔開。課文中有兩句話含有同位語(yǔ)：
I have just received a letter from my brother, Tim.
我剛剛收到弟弟蒂姆的來(lái)信。（Tim是my brother的同位語(yǔ)。它們指的是同一個(gè)人。Tim用來(lái)補(bǔ)充說(shuō)明my brother的名字）
He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia.
他剛買了一輛澳大利亞小汽車，現(xiàn)在去了澳大利亞中部的小鎮(zhèn)艾利斯斯普林斯。（在這句話中 a small town in the centre of Australia是Alice Springs的同位語(yǔ)，補(bǔ)充說(shuō)明這是個(gè)多大的鎮(zhèn)子，在什么地方）
在譯成漢語(yǔ)時(shí)，同位語(yǔ)或者插入主句中，或者另譯為一句，很少像英語(yǔ)中那樣用逗號(hào)隔開。請(qǐng)參閱課文中兩個(gè)句子的譯文。同位語(yǔ)如果太長(zhǎng)，可以另譯為一句。如課文中第二個(gè)例句的后半部分可以譯為：“現(xiàn)在去了艾利斯斯普林斯。這是澳大利亞中部的一個(gè)小鎮(zhèn)?！?同位語(yǔ)的其他例子如：
This is John, one of my best friends.
這位是約翰。他是我好的朋友之一。
Mrs. Smith, my neighbour, has never been abroad.
我的鄰居史密斯夫人從來(lái)沒有出過(guò)國(guó)。詞匯學(xué)習(xí) Word study
