Last month, students from one hundred and three universities in eighty-eight countries took part in an international computer programming contest. The Battle of the Brains took place in Harbin, China. 1.
Jerry Cain, coach of Stanford University Team, California, says “One of the programming problems was trying to figure out how to break a chocolate bar into a certain number of pieces of a certain number of sizes and to do it as quickly as possible. 2. ”
The students first listed the problems in order of difficulty. 3. They designed ways to test their solutions. And they wrote needed software systems. Even the winning team from Shanhai Jiaotong University in China was not able to solve all the problems within the given time limit. Stanford’s team solved five problems and finished in 14th place. Stanford was one of twenty-one American universities that took part in the contest this year.
4. . It began in 1970 at Texas A and M University. The contest quickly became popular in the United States and Canada. It developed and grew as more and more schools took part in local and area contests.
The first final competition was held in 1977 at the Association for Computer Machinery Computer Science Conference. Today, a network of universities holds area competitions that send the winners to the world finals, now organized by IBM. Contest spokesman Doug Heintzman says the world champions receive prizes and scholarships. 5.
A. The competitors show great interest in IBM.
B. Then they figured out the requirements of each.
C. And that’s probably the simplest of all of them.
D. This competition is an opportunity to be recognized by famous universities from the world.
E. Three-person teams from each school had five hours to solve eleven real world problems.
F. The official name of the Battle of the Brains is the ACM International Collegiate Programming Contest.
G. They are also guaranteed an offer of employment with IBM.
Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of aging on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20--25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the aging process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men,” said Goldspink.
They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.
The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

A Chinese couple tried to name their baby “@”, saying the character best represents their love for the child, according to an official trying to standardize the national language. The unusual name stands out especially in Mandarin, which has no alphabet (字母表) and instead uses tens of thousands of multistroke (多笔画的) characters to represent words. “The whole world uses it to write emails, and translated into Chinese it means ‘love him’,” the father explained, according to the deputy chief of the State Language Commission Li Yuming.
While the @ symbol is familiar to Chinese email users, they often use the English word “at” to sound it out. With a drawnout “t”, this sounds something like “ai ta”, or “love him”, to Mandarin speakers. Li says the name is an extreme example of people’s increasingly adventurous approach to Mandarin, as commercialization and the Internet break down conventions (习俗).
Another couple tried to give their child a name that in English sounds like “King Osrina”.
Li did not say if officials accepted the “@” name. But earlier this year the government announced a ban on names using Arabic numerals (阿拉伯数字) and foreign languages. Sixty million Chinese face the problem that their names use ancient characters so uncommon that computers cannot recognize them and even fluent speakers are left scratching their heads, said Li, according to a report on the government website. One of them is the former Premier Zhu Rongji, whose name has a rare “rong” character that gives newspaper editors headaches.

B. Because they wanted their baby to have an international name.
C. Because the @ symbol is familiar to email users all over the world.
D. Because the @ symbol sounds something like “ai ta”, which means “love him” in Chinese.
2.It can be inferred that ___________.
A. Li Yuming is in favor of the baby’s name
B. many Chinese people use Arabic numerals in their names
C. a majority of the Chinese people are having longer names
D. there is little possibility for the “@” name to be officially accepted
3.The underlined part in the passage probably means___________.
A. even native speakers find it hard to accept these strange names
B. even native speakers can’t find these characters in their computers
C. even those who are expert at Chinese can’t recognize these characters
D. even those who are expert at Chinese find it hard to accept these names
4.The former Premier Zhu Rongji is mentioned in the passage because ________.
A. people often mispronounce his name
B. there is an uncommon character in his name
C. he often made newspaper editors annoyed during his term in office
D. he once stressed the importance of standardizing Chinese characters

We all need a vacation, whether with the entire family or your significant other. Unfortunately, many of us will not be able to follow through with vacation plans. But now, there is an alternative that is catching on (流行起来) rather quickly and it is called a “Staycation”. A staycation is just what it sounds like, a vacation but you stay at home. It might not sound interesting, but you can turn it into a fun and relaxing getaway.
Tell family and friends your plans. In their eyes you are truly on vacation and they only need to contact you in case of an emergency.
Go outside; don’t let the kids sleep all day. Go out and birdwatch, go fishing, explore the parks and nature, take in all you can of the outside world. You can even have a relaxing day at the beach, soak in some sun, and let the kids go swimming.
Go on a picnic; have the kids fly kites. Bring some bubbles, and have a nice day with the wind blowing in your hair. Watch as the kids run and play and enjoy the beautiful outdoors.
Camping is another fun way to have a staycation. If you have a camping ground in your area, you can go camping for a day or two and show the kids how it is to live right in the heart of Mother Nature.
Just remember, it really doesn’t matter where you decide to go, whether home or away. As long as you create quality time with your family you can strengthen the bonds that may have been pushed aside during all the long stressful work hours. Time is the most important thing you can give to your husband, wife and kids, enjoying every moment together, and you will have lasting memories in your hearts.
