He spends all his spare time at the computer surfing the net.
對(duì) 話
Sibyl：My parents are getting quite worried about my younger brother.
Helen：Why, is he ill or something?
Sibyl：No, nothing like that.
Helen：Well, what is it?
Sibyl：He spends all his spare time at the computer surfing the net. He looks quite pale and unhealthy at times.
Helen：What are they going to do about it?
Sibyl：They want to make him join one of the local sports clubs and get some regular exercise.
Helen：I hope they succeed, but I know how stubborn he can be.
西柏：我父母有點(diǎn)擔(dān)心我弟弟
海倫：為什么？是他生病了，還是其它原因？
西柏：不是，都不是。
海倫：那是為什么？來(lái)源：www.examda.com
西柏：他一有空，就坐在計(jì)算機(jī)面前，作網(wǎng)上漫游。他有時(shí)看來(lái)臉色蒼白，很不健康。
海倫：你父母準(zhǔn)備怎么辦？
西柏：他們希望弟弟參加本地一個(gè)運(yùn)動(dòng)俱樂部，定期做些運(yùn)動(dòng)。
海倫：希望他們成功吧，但我知道令弟有時(shí)很固執(zhí)。
上一課的對(duì)話有I've been on my computer一語(yǔ)，今天的對(duì)話則有at the computer的說(shuō)法。這at和on有什么分別？On有‘使用（機(jī)器、設(shè)備）’的意思，例如He is on the phone（他在打電話）、I accompanied her on the piano（我彈琴為她伴奏）。At則有‘在旁邊’的意思，例如He sat at the desk（他坐在桌前）、She stood at the window waving at us（她站在窗前，向我們揮手）。所以，He is on the computer是說(shuō)‘他在使用計(jì)算機(jī)’，He is at the computer則是說(shuō)‘他坐在計(jì)算機(jī)前’。
網(wǎng)上漫游，英文叫net/Net/Internet surfing。Surf本是指‘做沖浪運(yùn)動(dòng)’，例如：They went to the bay to surf（他們?nèi)ズ硾_浪）。引申其義，上互聯(lián)網(wǎng)隨意瀏覽不同網(wǎng)站，也可用surf來(lái)說(shuō)，例如：(1) I surfed the net for information about AIDS（我上網(wǎng)漫游，搜尋艾滋病數(shù)據(jù)）。(2) Net surfing has become my number one hobby（網(wǎng)上漫游成為我大的嗜好）。說(shuō)到net surfing，不妨談?wù)刢hannel surfing。看電視，一會(huì)兒就轉(zhuǎn)往另一頻道，過(guò)一會(huì)兒再轉(zhuǎn)，如是多次，叫做channel-surf，例如：(1) He channel-surfed the television to see if there is anything worth watching（他試看一下各電視臺(tái)，看看有沒有值得看的節(jié)目）。(2) He channel-surfed so as to watch two soccer games at the same time（他要同時(shí)觀看兩場(chǎng)足球比賽，所以不斷轉(zhuǎn)換頻道
