1 . When water is cold, people will find it uncomfortable to swim. Wetsuits(潜水服）can help keep people warm.    1    So wetsuits are important. In many water sports, you can find people wearing them.

The wetsuit doesn't have a long history. According to studies, the wetsuit only began during WWII when Italians started wearing wetsuits that were made of rubber. And it was widely believed in 1951, Hugh Bradner began working to improve the equipment.     2    

Now there are many kinds of wetsuits. Contrary to what some may think, wetsuits do not work by keeping the diver(潜水员）dry; they are designed to let water into the suit. This thin layer of water is trapped（保存）between the diver and the suit. And it's allowed to move between the skin of the diver and the inside layer.     3    And it can help keep the diver comfortable during the diving process. That's why it's important to have a nice, tight fit for a wetsuit.

    4    The shorter wetsuit often provides cover for the main part of people's bodies. This kind of wetsuit works well with boating, water skiing, swimming, etc. A longer wetsuit can completely cover the body, including long legs.With more protection for the body, it may be used in cool weather conditions.

Wetsuits can also differ in thickness. They range from about 0. 5mm to 8mm in thickness. It's true that thicker wetsuits are more likely to affect your movement.     5    Generally, the colder the water you plan to dive in, the thicker the wetsuit should be.

9 . How to fight your bad breath

More than 80 million people suffer from bad breath, according to the Academy of General Dentistry, a professional association of dentists from Canada and the United States.     1    , the most common reason is poor oral hygiene (卫生). Here are some ways to fight bad breath and bring others talking to you a more pleasant experience.

    2    .

Onions and garlic add flavor to many foods, but they also add odors (臭味) not easily brushed away. The substances that cause their bad smells make their way into your bloodstream and travel to your lungs, where you breathe them out. The best way to avoid the problem is to avoid such foods.

Avoid dry mouth.

Saliva (唾液) is the key thing in your mouth that helps keep the odor under control because it helps wash away bacteria.     3    , try drinking water or chewing sugarless gum.

Brush and floss (用牙线清洁).

Oral hygiene experts recommend you brush your teeth at least twice a day and floss at least once to reduce plaque (牙斑). The sticky buildup on your teeth collects bacteria that cause bad breath, and trapped food adds to the problem.     4    , the experts warn. If you brush too hard you can wear down your teeth.

Brush your tongue.

    5    . To rid your tongue of odor-causing bacteria, remember to brush it when you clean your teeth. If your toothbrush is too big to reach the back of your tongue, buy a scraper, which is designed specifically to apply even pressure across the surface of the tongue area. This removes bacteria and dead cells that brushing alone can’t take care of.

A．Avoid certain foods

B．Don’t overdo things, though

C．If you aren’t producing much saliva

D．Bacteria don’t just live on your teeth

E．Brush your teeth after you eat these foods

F．Although bad breath can happen because of medical reasons

G．If your bad breath is thought to be caused by a potential health condition
