托福長(zhǎng)難句分析：機(jī)頂盒的產(chǎn)生

　　To make the technology as simple as possible, Sony, HP, and other vendors are finally creating software that can be used across all their devices—be it PCs, TVs, or set—top boxes.

　　為了讓科技盡可能的簡(jiǎn)單，索尼、惠普和其他銷售者最終開(kāi)發(fā)了可以在所有裝置上使用的軟件——不論是個(gè)人電腦、電視機(jī)或是數(shù)字解碼器——這種軟件就是機(jī)頂盒。

　　句首的不定式短語(yǔ)To make the technology as simple as possible作全句的目的狀語(yǔ);

　　主句為Sony, HP, and other vendors are finally creating software…;

　　定語(yǔ)從句：關(guān)系代詞that引導(dǎo)的定語(yǔ)從句that can be used across all their devices修飾先行詞software，that在從句中作主語(yǔ)，并且使用了被動(dòng)語(yǔ)態(tài);

　　第一個(gè)破折號(hào)后面是對(duì)across all their devices的具體說(shuō)明，注意這里采用了whether…or…引導(dǎo)的讓步狀語(yǔ)從句省略whether的特殊形式be it PCs, TVs, or set;

　　第二個(gè)破折號(hào)后top boxes是對(duì)software的最終闡釋，我們?nèi)サ糁虚g讓步狀語(yǔ)作的分隔成分，可以連接全句為Sony, HP, and other vendors are finally creating software that can be used across all their devices—top boxes。
