题目内容

16．The students hold their breath when their teacher read the final list．hold改为held．

分析当老师宣读最后名单时学生们屏住气．

解答答案是将hold改为held．when从句中的主语teacher是第三人称单数，但是谓语动词read没有用第三人称单数，故判断此处read为过去式（read的过去式与原形相同）；从句是过去时，该句主句也应该是过去的事件，故答案是把hold改为held．

点评本题改错考查时态，要从上下文中寻找时态依据；本题要根据when引导的时间状语从句中的时态判断主句动词的时态．

7．Third-generation mobile phones，known as 3G，are the next big step for the electron industry．Data speed in 3G networks are much quicker than present technology．This means users can have high-speed Internet access and enjoy video and CD-quality music on their phones．
"Mobile data is not a dream； it's not an option but a requirement，"said Len Lauer，head of a US communications company，Sprint PCS，at a 3G conference in Bangkok earlier this month．
With 3G，you can forget about text messages telling you yesterday's news； a 3G phone can receive video news programs，updated four times a day．Internet access will also be much quicker，making it easier to surf the Web on your phone than on your computer at home．
Face-to-face video calls
And don't worry about getting lost.3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset．
However，the most impressive part of 3G technology is video calling．With live two-way video communication，you can have face-to-face talks with friends and family on your mobile phone．
Many European countries have already launched the service．In May 2000the US Government issued five license to run 3G wireless services，while the first 3G phones arrived in Italy in March this year．
International telecom companies can't wait to sell 3G in China，the world's largest mobile telecommunications market．But they will have to be patient．At the moment，China is busy testing its 3G-based technologies，networks and services．This will be followed by a trial period before the phones can finally hit the shops．
"We need to create a pool of 3G customers before the large-scale commercial launch of the service，"said Fan Yunjun，marketing manager for Beijing Mobile．"We expect that the 3G licenses will be issued late next year．"

5．It's amazing how we grow from careless kids to responsible teens．What happens in the course that makes us responsible now？It's the seed that we sow in the beginning which grows and becomes a huge tree．As I sit here，silently thinking about my growth，I wonder over some questions which don't have an answer but it's because of such unanswerable situations that life has become a roller coaster ride．
As a kid，I used to read a lot of story books．In one particular book，I read a story of a bird．From then on，that has become an integral （必不可少的） part of my life．It described a male bird which takes a lot of pain to build a nest and the female bird takes shelter in it and nourishes the baby．When the bird learns to fly，the whole family flies off to a different place leaving behind the beautiful nest for other birds to grow their family in it．It made me wonder．How could they so easily sacrifice their house built with so much effort？
One night，when I was deep in sleep，I got this particular dream．I was walking miles on the endless road，totally isolated but lined with beautiful trees on the either side．Fascinated by the greenery，I marched towards it only to end up deeper and deeper into the greenery．I happened to stop upon seeing something．It was a massive，wonderful house．I fell in love with that amazing part of art．Yeah，it was indeed a piece of art with every nook and corner touched artistically and lovingly．I don't know why I felt that it was done lovingly．Maybe because，things turn out to be beautiful only when we put our love into it-just like the food prepared by mom which tastes more delicious with her love．
I explored the house only to fall more in love with it．There was a sloping roof which matched with the greenery around； the large central open courtyard reminded me of the activities that might have taken place there which felt lively even now when it is completely deserted．The small water body that kept the house cool added to the beauty of the house-of course，it was all dried up now．It's really wonderful how such things add life to the spaces which otherwise just become structures．Such liveliness and happening turns the house into a home．They say‘THE HOME IS WHERE THE HEART IS'，but now I began to feel it．This is where my heart belongs．This is what I'm destined to do．
When I woke up from the dream，I was clear about everything．I realized where that mile of walk was intending me to lead．I realized what message my dream wanted to convey me．And years later，when finally my turn of choosing my destination came，I simply closed my eyes，held that book in my hand，pressed it against my chest and relived the dream．When I opened my eyes，I was sure what to do．I decided to choose the road-less traveled．Yes，I took up architecture as my profession because this is what I am destined to do．I wanted to do the same thing that the male bird in the story did，to take pain in building a beautiful house and let others stay in it．This is my dream come true and the happiness that I gain now from this profession is indescribable．
