4．-What time do we have to be at the gate？
-____ passengers are already boarding．（　�。�
A．HurriedlyB．SoonC．ImmediatelyD．Since

分析 -我們必須什么時(shí)間達(dá)到登機(jī)口？-乘客準(zhǔn)備登機(jī)的時(shí)候必須馬上就位．

解答 答案：C  句意問的是時(shí)間，回答應(yīng)該是時(shí)間；passengers are already boarding是一個(gè)時(shí)間狀語從句，要用從屬連詞來連接，AB是副詞，不是連詞；since引導(dǎo)時(shí)間段，what time問的是時(shí)間點(diǎn)；immediately立即，馬上，可以起連詞的作用．故選C．

點(diǎn)評(píng) 副詞辨析是常考的知識(shí)點(diǎn)，副詞數(shù)量眾多，用法靈活．學(xué)習(xí)時(shí)，要注意積累．本題考查的是副詞的特殊用法，充當(dāng)連接詞，引導(dǎo)時(shí)間狀語從句．

10．A dog-lover has invented a high-tech way of feeding his pet by Twitter（推特，流行社交網(wǎng)絡(luò)）．Computer expert Nat Morris，30，has designed a system to give his pet a"tweet treat"by sending him a Twitter message．
His dog Toby gets some delicious dog biscuits from a computer-controlled food machine whenever Nat sends a message to"@feedtoby"．
Nat often works away from home and isn't always able to feed Toby by hand．But his new invention  allows Nat to feed his dog from anywhere in the world．
Nat said，"Toby absolutely loves it．At first he didn't know what was going on．Now he sits underneath the machine，wagging his tail and waiting for the treats to drop．"
Nat fills the food machine with small pieces of dog biscuits，but not too many in case four-year-old Toby gets too many messages．And Nat has even equipped his house with an online camera so he can see Toby enjoying the food at his home．
But one problem is that friends and family have been so amazed with the"Tweet treat"machine that．they have starting to send tweets to Toby too．So Nat has had to restrict feeding time to make sure Toby doesn't turn into Tubby．
"People have been sending him food at all hours of the day，so I had to limit it to between 9 a．m．a(chǎn)nd 9 p．m..I'm thinking of doing an updated one which measures his weight before he is fed，just to make sure he's not putting on too much puppy fat，"explained Nat．
How Nat's Twitter Feeder Works：
When a message is sent to@feedtoby it is received by a mini-computer that is linked to the food machine．
When the mini-computer receives the message，a bell rings and Toby comes running over and sits in front of the feeding machine．Next the machine's motor pulls open a trap door which releases a serving of food．
The doggy biscuits then drops into Toby's food bowl．Finally a digital camera takes a photo of him and sends it back to Nat on Twitter-so he knows Toby has been fed．
