Different ways of speaking are part of gender. As adults, men and women sometimes face difficulties in their communication with each other. Studies of communication show that if a woman tells her husband about a problem, she will expect him to listen and offer sympathy. She may be annoyed when he simply tells her how to solve the problem. Similarly, a husband may be annoyed when his wife wants to stop and ask a stranger for directions to a park or restaurant. Unlike his wife, he would prefer to use a map and find his way by himself.
Language is also part of the different ways that men and women think about friendship. Most men believe that friendship means doing things together such as camping or playing tennis. Talking is not an important part of friendship for most of them. Women, , usually identify their best friend as someone with whom they talk frequently. Experts believe that for women, talking with friends and agreeing with them is very important.

After a series of building problems and public protests in Brazil, the governing body of world football, Fifa, repeatedly warned there would be “no compromise” over the delivery of World Cup stadiums. But with Fifa’s endof- year deadline looming, several stadiums are well behind schedule and one host city, Cuiaba, has told the BBC that not only will it be unable to finish its stadium on time, but there are not even enough hotel rooms for visiting fans.
Even though Fifa only insisted on a minimum of eight stadiums to host the World Cup, Brazil decided to go with 12, such was the interest and demand from all parts of this huge nation to be part of the tournament. But, in hindsight, has Brazil bitten off more than it can chew? Up in the city of Manaus, they are finishing an arena that bears some resemblance to the famous Bird’s Nest Stadium in Beijing: an elaborate steel structure, imported from Portugal, envelops the playing area like an indigenous woven basket.
