ace level (i.e. the complement of a mark) for one element period. This element is called the start bit and has a duration of T seconds. The transmitter then sends the character, l bit at a time, by placing each successive bit on the line for a duration of T seconds, until all bits have been transmitted. Then a single parity bit is calculated by the transmitter and sent after the data bits. Finally, the transmitter sends a stop bit at a mark level (i.e. the same level as the idle state) for one or two bit periods. Now the transmitter may send another character whenever it wishes.

At the receiving end of an asynchronous serial data link, the receiver continually monitors the line looking for a start bit. Once the start bit has been detected, the receiver waits until the end of the start bit and then samples the next N bits at their centers, using a clock generated locally by the receiver. As each incoming bit is sampled, it is used to construct a new character. When the received character has been assembled, its parity is calculated and compared with the received parity bit following the character. If they are not equal, a parity error flag is set to indicate a transmission error.

Questions 36 to 40 are based on the following passage:

On line courses (also called distance learning) are a hot new trend in American education. According to the nonprofit Distance Education and Training Council,　about 400 US colleges and schools offer some portion of their programs on the We b. At the university level, they cost the same as traditional classes and requir e similar weekly assignments and textbook reading, the difference is in class pa rticipation.

Generally speaking, students congregate(使聚集) on line throughout each week to explore topic with the professor, but these discussions occur “asynchronousl y(不同时发生地)” rather than in real time. (You read others’ comments and post your own whenever you get a chance.) Written assignments are posted, you e mail in your work periodically, and you’re required to take a proctored exam in order to receive degree credit. Career boosting business administration and information technology programs are the most popular, but you’ll also find a variety of literal arts offerings, from film theory to medieval history and foreign lang uage study. While you still can’t get an Ivy League degree on line, a growing number of elite(卓越的) institutions, including Stanford and New York Univer sity are beginning to offer on line courses.

The benefits for busy people are obvious. “I always get a front row seat,” says one student studying at the State University of New York Learning Network. “I can get up in the middle of class, grab a cup of coffee. The class is waiting for me when I get back, and I haven’t missed a thing.” On the other hand, some students miss the face to face interaction that often sparks interest and involvement.

36.Generally speaking, on line education costs ____.

A.more than the traditional one B.less than the traditional one

C.as much as the traditional one D.the author hasn’t mentioned

37.The major way to hand out assignments of on line students is ____.

A.to hand out them in person

A.Software development. B.Decoration and design.

C.International trade. D.Company management.

39.The closest meaning of “Ivy League” (Par. 2) ____.

A.famous universities in USA

B.famous business colleges in USA

C.famous companies in USA

D.universities with a long history

40.It is implied that in USA ____.

A.on line education will take the place of the traditional one soon

B.there are only a few on line programs until now

C.one need not take part in the exam in order to receive a diploma by way of on line education

Passage Two

Questions 51 to 55 are based on the following passage.

You probably know about the Titanic, but it was actually just one of three state-of-the-art (最先进的)ocean ships back in the day. The Olympic class ships were built by the Harland & Wolff ship makers in Northern Ireland for the White Star Line company. The Olympic class included the Olympic, the Britannic and the Titanic, What you may not know is that the Titanic wasn’t even the flagship of this class. All in all, the Olympic class ships were marvels of sea engineering, but they seemed cursed to suffer disastrous fates.

The Olympic launched first in 1910, followed by the Titanic in 1911, and lastly the Britannic in 1914. The ships had nine decks,and Whits Star Line decided to focus on making them the most luxurious ships on the water.

Stretching 269.13 meters, the Olympic class ships were wonders of naval technology, and everyone thought that they would continue to be so for quite some time. However, all suffered terrible accidents on the open seas, The Olympic got wrecked before the Titanic did, but it was the only one to survive and maintain a successful career of 24 years. The Titanic was the first to sink after famously hitting a huge iceberg in 1912. Following this disaster, the Britannic hit a naval mine in 1916 and subsequently sank as well.

Each ship was coal-powered by several boilers constantly kept running by exhausted crews below deck. Most recognizable of the ship designs are the ship’s smoke stacks, but the fourth stack was actually just artistic in nature and served no functional purpose. While two of these ships sank, they were all designed with double hulls(船体)believed to make them “unsinkable”, perhaps a mistaken idea that led to the Titanic’s and the Britannic’s tragic end.

The Olympic suffered two crashes with other ships and went on to serve as a hospital ship and troop transport in World WarⅠ. Eventually, she was taken out of service in 1935, ending the era of the luxurious Olympic class ocean liners.

What does the passage say about the three Olympic class ships？

A.They performed marvelously on the sea

B.They could all break the ice in their way

C.They all experienced terrible misfortunes

D.They were models of modern engineering

What did White Star Line have in mind when it purchased the three ships？A.Their capacity of sailing across all waters

B.The utmost comfort passengers could enjoy

C.Their ability to survive disasters of any kind

D.The long voyages they were able to undertake

What is said about the fourth stack of the ships？A.It was a mere piece of decoration

B.It was the work of a famous artist

C.It was designed to let out extra smoke

D.It was easily identifiable from afar

What might have led to the tragic end of the Titanic and the Britannic？A.Their unscientific designs

B.Their captains’ misjudgment

C.The assumption that they were built with the latest technology

D.The belief that they could never sink with a double-layer body

What happened to the ship Olympic in the end？A.She was used to carry troops

B.She was converted into a hospital ship

C.She was sunk in World WarⅠ

D.She was retired after her naval service
