A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.

Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma

Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.

But questions has been raised about sunscreen and whether it may have opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.

The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.

The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.

While serious training is important for all dogs, playtime is just as important. 36 Use these games to help teach your dog how to play.

1.Hide and Seek

Hide and seek isn’t just for kids. Dogs can really enjoy this game. Pick up one of your dog’s favorite toys or treats. Tell your dog to stay. 37 When you are ready, call your dog to come to you. If possible, squeak(使吱吱叫) the toy or shake the treats. Reward your dog with praise and the toy treats when she finds you.

2. Fetch

Many dogs have a natural ability to fetch. Other dogs can be taught how. 38 Play indoors with a soft toy or outdoors in a fenced-in area with a ball or disc. For dogs that really love to run, try this game of fetch!

3. Find the Treat

Dogs have superior senses of smell, and most love to use their noses to find food. Let your dog use her brain and her nose to find hidden goodies. First, have your dog stay out of sight. Then，hide her favorite treats in different places around the room. 39 If help is needed，you can lead her around or point to areas for her to explore.

Whatever the game, safety comes first! Remember to watch your dog for signs of exhaustion or overheating when you are playing. Stop if your dog seems tired or shows signs of anxiety.

40 When other dogs or people are around, it may create a dangerous distraction (分神).

Yesterday morning I was surprising to hear that my friend Allen had been hit by a car and was in hospital. The other day he is going to cross a street. He was very careful and didn’t go after he saw traffic lights turn green. But when he got the middle of the street he saw a car suddenly appear on her right-hand side and come directly towards him. That was too late for Allen to dodge(躲闪). He was hit by a car and thrown a few meter away. He was sent to hospital immediate and had an operation. When I went to see him the last night, he was out of danger but still looked pale.
