9．電視機已開了幾個小時了，你介意關掉嗎？
The TV sethas been on for a few/several hours．Do you mind turning it off？

分析電視機已開了幾個小時了，你介意關掉嗎？

解答答案：has been on for a few/several hours
考查漢譯英．根據題干：電視機已開了幾個小時了，你介意關掉嗎？The TV set．Do you mind turning it off？可知時態是現在完成時，主語是The TV set第三人稱單數，故助動詞用has，系動詞be的過去分詞是been，開用on，幾個小時用 a few/several hours一段時間前面用介詞for，故答案是has been on for a few/several hours．

點評考查漢譯英．根據所給的句意，用合適的固定搭配，時態等完成句子是關鍵．

12．Now，everybody is taking selfies．From your best friend to your favourite pop star，selfies are taking over Facebook and Sina Weibo．The word"selfie"was even named Word of the Year by Oxford Dictionaries in 2013．But why do people feel the need to take them？And are they doing us more harm than good？
According to some scientists，humans have an area in their brain that controls social activity．Receiving‘LIKE'on a selfie you have posted online can be the same as someone stopping you in the street and speak highly of you on your appearance．
The act of taking a selfie also puts you in a position of power．You are the director and the subject of your own work of art．It helps people feel in control of their appearance and can be a powerful tool．
But can it go too far？Scientists warn that too much time spent on selfies can influence people's confidence，especially in teenagers．If you are spending a lot of time choosing the perfect selfie clothes，then there could be a problem．
At the same time，posting selfies online can harm your personal relationships．UK studies found that many people find it hard to talk to people who are often posting selfies online．
So next time you want to use your smartphone（智能手機） to take a quick selfie，it may be better to drop it straight back into your pocket．

28．What does the underlined word‘selfies'mean？A
A．Pictures of yourself，usually taken by yourself．
B．Pictures of your best friends，usually taken by you．
C．Pictures of yourself，usually taken by others．
D．Pictures of your favourite stars，usually taken by you．
29．What does the passage mainly talk about？D
A．People like taking selfies．
B．Why people often like taking selfies．
C．How people take more beautiful selfies．
D．What good and harm taking selfies brings to people．
30．The writer thinks taking selfiesB．
