12．A person who has never tasted bitter won't know ______ sweet is．（　�。�
A．whichB．whatC．whenD．why

分析 一個從來沒有經(jīng)歷過苦難的人是不會知道幸福是什么的．

解答 答案：B
person后面有個who引導(dǎo)的定語從句．動詞know后面是一個賓語從句，其主語是sweet，系動詞is后面缺表語．CD兩項(xiàng)是連詞副詞，只能在句中做狀語，不能做表語．Which表示疑問，強(qiáng)調(diào)具體范圍之內(nèi)的"哪一個"．所以使用what，既引導(dǎo)起這個賓語從句，也在賓語從句中做系動詞is的表語．故B正確．

點(diǎn)評 對于賓語從句的引導(dǎo)詞要明白其在句中所充當(dāng)?shù)某煞郑髻e語時�？墒÷裕鏘 don't know that he has been abroad．

5．   In Silicon Valley，it's never too early to become an entrepreneur．Just ask 13-year-old David Moore．The eighth-grader has launched a company last October to develop low-cost machines to print Braille （布萊葉盲文）．David built a Braille printer with a Lego Mindstorms EV3kit as a school science fair project last year after he asked his parents a simple question：How do blind people read？"Google it，"they told him．David then did some online research and was shocked to learn that Braille printers cost at least 2，000dollars-too expensive for most blind readers．
"I just thought that price should not be there．I know that there is a simpler way to do this，"said David，who demonstrated how his printer works at the kitchen table where he spent many late nights building it．David wants to improve the"Braigo"-a name that combines Braille and Lego-and develop a desktop Braille printer that costs around 350dollars and weighs just a few pounds，compared with current models that can weigh more than 20pounds．"My end goal would probably be having most of the blind people…using my Braille printer，"said David，who lives in the Silicon Valley suburb of Santa Clara，just minutes away from Intel headquarters．
 After the Braigo won numerous awards and enthusiastic support from the blind community，David started Braigo Labs last summer with an initial 35，000dollars investment from his dad．"We as parents started to get involved more，thinking that he's on to something and this new way process has to continue，"said his father，Matthew Moore，an engineer who works for Intel．
Intel officials were so impressed with David's printer that in November they invested an undisclosed sum in his start-up．They believe he's the youngest entrepreneur to receive venture capital money invested in exchange for a financial stake in the company．"He's solving a real problem，and he wants to go off and challenge an existing industry，"said Edward Ross，director of Inventor Platforms at Intel．Now the company is using the money to hire professional engineers and advisers to help design and build Braille printers based on David's ideas．It aims to have a prototype （樣機(jī)） ready for blind organizations to test this summer and have a Braigo printer on the market later this year．

66．Which of the followings is Not the description of Braigo？C
A．The name"Braigo"comes from Braille and Lego．
B．The blind are in favor of the new type of printer．
C．It costs less money and weighs just a few pounds．
D．David planned to improve Braigo and make it lighter but easier to use．
67．Which of the following words can best describe David's personalities？D
A．Adventurous and enthusiastic．
B．Trustworthy and active．
C．Childish and outgoing．
D．Creative and independent．
68．Which of the following is the correct order？A
①．Intel officials invested money in David's start-up．
②．David launched a company．
③．David got an initia l35，000dollars investment from his dad．
④．David created a new Braille printer model called Braigo．
⑤．Braigo Labs hired professional engineers and advisers to help design and build Braille
Printers．
A．④③②①⑤
B．④②⑤①③
C．③⑤④②①
D．②①④⑤③
69．What can we learn from Paragraph 4？A
A．Intel didn't announce the amount of money it invested．
B．No one else has ever received venture capital from Intel．
C．Intel purchased David's ideas to design and build Braille printers．
D．Braigo printers have been on the market and proved a great success．

In the tiny village of Angelica, New York, the post office is more than a place to get mail or send packages. There you’ll find the heart of this lovely community. It’s where villagers meet and greet friends.

When Angelica’s post office was threatened with being closed in the 1980s，a villager，Pat, came up with a plan to save it. “At Christmas time I would hear on the news about towns named Snow or Bethlehem having celebrations,” says Pat, “Why couldn’t we do the same thing with Angelica?”

Pat, who is an artist，created a postal cancellation (郵戳) design featuring an Angelica angel.

She drew her angels in a traditional fashion and submitted her suggestion to the U.S. Postal Service. Once approved, the drawing was carved into a cancellation stamp that could be used for one day only. The postmistress (女郵局局長) then had another idea to make the day even more special calling the post office Angel Station.

The large increase in mail amount saved Angelica’s post office from being closed and keeps the doors open today.

Now it’s tradition that on the first Friday in December，people come to Angelica to mail their Christmas cards. Each year the amount of mail going through the Angelica Post Office increases during late November and early December. Stamp collectors from around the world have accepted the Angel Station cancellation, some sending mail from as far away as France.

Because the stamp is destroyed each season, Pat draws a new angel that conveys season’s greetings from Angel Station every year. Post offices may close in other parts of the country, but this tiny one continues.

1.What did Pat do to save the post office?

A. She invented a new cancellation. B. She hosted Christmas celebrations.

C. She gave the office a better name. D. She designed a special set of stamps.

2.Which of the following can best describe Pat?

A. Stubborn and determined. B. Humorous and intelligent.

C. Curious and friendly. D. Creative and warm-hearted.

3.What can we learn about Angelica’s post office from the passage?

A. It was complately closed in the 1980s.

B. Its name has been changed many times.

C. Its stamp remains the same each season.

D. It is also the centre of local social life.

According to the trials of comprehensive college entrance examination reform that the State Council has made．some of the subjects will be examined many times in a year．People have different opinions about this．
Some say that this program gives students more free time．Students can choose the exam time themselves and it's obviously an effective way to improve their grades of the university entrance examination．In addition，if some of the subjects are finished ahead of time，students will be in less pressure during the time．
However，there are also many people against the program．They hold the view that it will increase the burdens of the students by frequent tests．Also，it is a waste of education resources because the exams will cost more in this case．
In my opinion，to pass the exam before the fixed time is a good way to relax ourselves while we are all under the pressure of the university entrance examination．So I'm looking forward to seeing the reform program brought into force．．
