The end of the World Cup does not mean the end of international competition, in Brazil this year. A major football event will happen in the South American country later this month, but with teams of robots playing the game, which is known as soccer in the United States.

Technology students at the University of Pennsylvania are trying for their fourth victory at the competition, which is held this year in the coastal city Joao Pessoa. The students have won the last three RoboCup competitions. Watching robots play football is similar to watching children play the game.

British men are encouraged to cry. There are certain things British men like to believe about themselves. The first is that one day they will again win the World Cup. They also believe they do not cry. Over the centuries, Britons are believed to have a "stiff upper lip". But is this true? Yes, it is. A recent study arranged by Kleenex on how the British express their emotions reveals that 95 percent of them still _ their emotions. Moreover, while 72 percent think this is unhealthy, 19 percent can't remember the last time they "let it out". As a result, Kleenex is launching the "Let It Out" campaign that encourages Britons to grab a tissue and have a good cry. These days, however, the male Briton's attitude toward crying is changing. Though the majority still struggles to open up emotionally, a 2004 study by Oxford's Social Issues Research Center found that 77 percent of British men considered crying in public increasingly acceptable. Half of London males admitted crying in front of their mothers. Scotsmen are the least emotional, although they are the most likely to cry at weddings. Peter Marsh, director of the center, said, "Crying can now indicate sensitivity rather than weakness. Like with David Beckham, crying because you're dropping off your boy at nursery isn't seen as weak." Winston Churchill was said to be a frequent crier, shedding tears at seeing a survivor in an air raid shelter , and when he saw his wife after a long absence. Psychologists say that while society has accepted that men can cry, there are limits. Ronald Bracey, a consulting psychologist, said, "If a man began to cry when he was having stitches in hospital, he would be considered as a wimp . Men still need to be seen as strong when it comes to physical pain. " Which of the following concerning the British men is NOT true according to the passage? A) They are supposed to easily control emotions over the centuries. B) They are confident that they will again get successful in the World Cup. C) Nowadays, the male Briton's attitude toward crying is changing. D) About 50% of Britons admitted crying before their mothers.

You've bought what you need. The grocery cashier asks, "Will that be paper or plastic? You reply "Plastic, please." This seems like a simple question and there are plenty of reasons we choose plastic: easier to carry, lighter than paper bags, possibly less damaging to the environment, less expensive to the shop owners, able to be used as trash bag, and so on. There are different opinions on plastic and paper. Now let's follow the travels of 3 plastic bags. It begins at the grocery store with the customer's choice. Plastic Bag 1: As the waste engineer come by and pick up the trash, the first plastic bag falls out. It sits on a small street for a couple of hours until a car comes along and takes it down to the road. Then a gust of wind blows it across the road, then another car, then another gust of wind finally makes its way to the beach. Water fills the plastic bag and makes it look like a jellyfish. A seal swims by, thinking it looks very interesting, and swallowed it. The plastic bag may stay in the seal's stomach for months, maybe years. You see, our lovely animals have been living thousands of years in a world where everything can be eaten. Plastic Bag 2: This bag does make its way to landfill . Before they have a chance to cover up the thousands of pounds of daily waste, a strong wind comes up and blows these plastic bags out of the landfill. Once the wind stops, workers will be sent to collect thousands of bags around. But they can't possibly get them all. So our little bag continues his adventure getting caught in trees, eaten by birds or making its way to our lakes or rivers. Plastic Bag 3: The last bag also blows away but is caught in a landfill where it sits for many years, as all the trash is wrapped in a big plastic bag, making natural degradation impossible. Although workers do much work to make sure water and air system won't be polluted, some do. Guess what, plastic bags are made from petrol, a harmful waste material, which in one way or another makes its way to the environment. Another... Wrapped in a big plastic bag, Plastic Bag3 _ . A) still does harm to the environment B) can hardly be harmful to the environment C) is much safer than Plastic Bag2 D) will end up being eaten by seals or some fish
