"Aha!" he exclaimed as he picked a hair off the lapel of the dead man's coat." The mystery is a mystery no longer. We have only to find the man who lost this hair, and the criminal will be in our hand." The inexorable chain of logic was complete, and the detective embarked on his search.

The man was about to board the Gloritania, and the detective lost no time in following him on board.
"Arrest him!" shouted the detective, and then, drawing himself to his full height, he brandished aloft the hair." This is his," said the great detective," and it proves his guilt" .

Large universities are offering more courses in the evenings for adult students. In this way, the demand for more education is being met.

Task 2
Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.
People in some countries cannot use their native languages for Web addresses. Neither can Chinese speakers, who have to rely on pinyin. But last Friday, ICANN, the Web's governing body, approved the use of up to 16 languages for the new system. More will follow in the coming years.
The Internet is about to start using the 16 languages of the world. People will soon be able to use addresses in characters(字符) other than those of the Roman alphabet(字母表). The change will also allow the suffix(后缀) to be expressed in 16 other alphabets, including traditional and simplified Chinese characters.
But there are still some problems to work out. Experts have discussed what to do with characters that have several different meanings. This is particularly true of Chinese.
Most experts doubt the change will have a major effect on how the Internet is used. "There will be some competition between companies to obtain popular words for addresses."
For Web addresses, Chinese speakers now have to use______.
