16．─When you entered the room，did you notice_______ there？
─No，I didn't．I saw______ in it．（　�。�
A．anyone； somebodyB．anybody； nobody
C．somebody； no oneD．somebody；anybody

分析 --當(dāng)你進(jìn)入房間的時(shí)候，你注意那有人了嗎？
--不，我沒注意到．我在房間里沒看到人．

解答 答案：B．考查不定代詞．句意"--當(dāng)你進(jìn)入房間的時(shí)候，你注意那有人了嗎？--不，我沒注意到．我在房間里沒看到人．"，第一個(gè)空，一般疑問句somebody改為anybody，C，D不正確．第二個(gè)空，根據(jù)題意"我，我沒注意到"可知，應(yīng)該是沒人，A不正確．答案是B． anyone通常指一個(gè)人，anybody通常指多人．nobody 和 no one意思一樣，都表示"沒有人"，可做主語和賓語，但nobody還可以表示"無關(guān)緊要的人"，做表語．

點(diǎn)評 不定代詞大部分可以代替名詞和形容詞，在句中作主語、賓語、表語、定語和狀語．要結(jié)合具體的語境，認(rèn)真分析，正確完成試題．

3．When I was seventeen，I found a watch while walking down the hallway of my high school．As I picked it up，greed（貪婪） suddenly came over me and I decided to keep it．
When I got home from school，I found my mother cooking dinner in the kitchen．I proudly held out my prize for her to see．Mom was angry that I had kept the watch instead of turning it in．Mom then ordered me to drive straight back to the school and take the watch to someone at the office．I started to argue，but after taking a good look at the serious expressions on Mom's face，I realized it would get me nowhere．
As time passed，I forgot all about the watch until four years later．
While I was attending college，I had managed to get a job at a supermarket pushing carts（推車） off the parking place．One morning，I found a checkbook（支票簿） that had been left in a shopping cart．Immediately，I gave it to the boss there so that the customer who had lost it could pick it up．
Later，as I was outside pushing carts，a man came up to me and told me that his wife had left their checkbook in a shopping cart the night before．When he told me his name，I realized he was the owner of the checkbook I had found．I explained to him that he could go inside and get it back at the service desk．
The look on the man's face was gratitude（感恩）．He pulled out his wallet and offered me some money，but I refused．I was proud of myself，prouder than I had been in a long time，and I wasn't about to let something like money destroy that．
Suddenly，the lesson my mom had taught me that day came into focus．Mom wanted to make sure that her son would always be honest．Because of her，I did the right thing when I found that checkbook．Because of her，I had got a feeling of self-worth that no amount of money could buy．
34．What did the writer realize after looking at his mom's face？D
A．His expression wasn't natural     
B．His watch impressed her deeply
C．His prize made her feel proud     
D．His argument made no sense．
35．What does the underlined word"that"refer to in Paragraph 6？B
A．cash             
B．pride            
C．gratitude            
D．shyness
36．From the passage，we know that the writerB
A．did a part-time job at a supermarket   
B．found the owner of the checkbook
C．guided cars at the parking place      
D．led the man to the boss at the service desk
37．The best title for the passage may beC
A．Looking for the loser             
B．The way to realize Self-Worth
C．Getting away with greed          
D．Doing the right thing．

8．Do you have imagination？Do you like to solve problems？Can you think out of the box？If so，you could be the next great inventor．"But I'm just a kid，"you might say!Don't worry about a little thing like age．Some of the greatest inventors in the world get their start as kids．
For example，Benjamin Franklin created paddles （槳） for his hands to help him swim faster when he was only 12 years old．His creation led to today's flippers （橡膠蹼）!
You don't have to be an adult，a scientist or a genius （天才） to be an inventor．One thing you need is：curiosity and imagination．Kids are known for looking at things in new and uniqueways．Sometimes their understanding of things leads to great inventions!
Sometimes inventors come up with completely new things that solve a problem．At other times new inventions are only things that are changed or improved．Then they work better or serve a different purpose．
So what should you do if you have a great idea for an invention？Talk to a friend of family member about it．Ask them to help you create a working model of your idea．
Once you have a working model，you should test it．Sometimes after the test，you may find your idea is not as great as you thought．At other times you realize it is a good idea and your working model can help you work out how to make it better．
If you need some ideas，consider these kids and their inventions：
Frank Epperson invented Popsicles （冰棍） when he was 11．One night he mixed soda powder （蘇打粉） and water with a stick．He left it outside all night．The next morning，he found that the stick had frozen （凍結(jié)） inside the drink during the cold night．
Chester Greenwood created earmuffs （耳罩） when he was 15．He found his ears got painfully cold when he was skating．He decided to solve the problem．He found a piece of wire （電線），and his grandma helped him pad （用軟物填塞） the ends．
At the age of 15，Louis Braille invented the system that allowed blind people to read．
52．The underlined word"unique"in Paragraph 3 probably means"C"．
A．strict                  
B．famous                   
C．unusual                   
D．popular?
53．We can learn from the passage thatD．
A．Benjamin Franklin made paddles for his feet
B．Frank Epperson spent many days making Popsicles?
C．Chester Greenwood created earmuffs with his teacher?
D．Louis Braille's invention helped blind people to read?
54．The writer probably agrees thatD．
A．a(chǎn)ge is very important for inventions
B．kids inventors are geniuses?
C．inventions should be completely new
D．a(chǎn) working model needs to be tested
55．What is the best title of the passage？B
A．Are Inventions Important？
B．Can Kids Be Inventors，Too？
C．What's Your Favourite Invention？
D．How Can You Make Inventions Popular？

VR is a computer technology that makes an environment and allows users to see and even interact （互動(dòng)） with it．Just wear a pair of VR glasses joined to your computer and you can experience a lot of things without stepping out of your room．
"The most interesting part of VR is that it offers an immersive experience，"said Wang Bing，leader of the Chinese entertainment company Funshow．"That's why VR movies are popular among users．You become a part of the story．"According to the Report on Chinese VR Users'Behavior last month，over 960，000people in China have bought VR products and 83.2percent of them have watched VR movies．
VR can also be used in some other ways．It can help to train workers before they have to work in highly dangerous environments．VR also helps patients with acrophobia （恐高癥） by making them think they are standing on the top of a tall building．
However，VR technology still has a long way to go．Users report feeling sick while wearing VR glasses．Maybe it could take a period of time for VR to be widely used around the world．
