2 . 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.

7 . There’s a child-like joy that comes with ordering something online — whether it be clothes or kitchen facilities. We sit refreshing the postal service to see when our items will arrive, and we become overly excited, hopeful and anxious.

Ryan Howes, a clinical psychologist from Pasadena California, has interpreted this phenomenon as “anticipatory pleasure”. “A lot of people believe that placing that order and waiting for it does feel good. This is why people look forward to dinner reservations, hair appointments and yes, receiving packages,” he says.

But it’s not the purchase itself that brings about this happiness. Experts say there’s something about the anticipation of waiting that is exciting for those in need of change in their lives. “It can be helpful to anticipate good things in the future, ’’says Ryan Howes. “Waiting for a parcel can serve as a temporary distraction (分心) from the dullness of your life because it gives you something new to wake up to and get excited about.”

However, anticipatory pleasure isn’t always a good thing. While waiting, many are worried about their items arriving on time, appearing broken, or simply not living up to expectations. Even when our package finally arrives, you’ll find that initial excitement has probably waned. Howes cautions that comfort shopping is only a temporary fix. It’s just a distraction from bigger problems, but it hasn’t done anything to change the bigger problems. It only helps you escape from them temporarily.

“Many people often seek external solutions, such as luxury purchases or alcohol, as a way of feeling better quickly. However, a healthier long-term curing mechanism is to look inward and appreciate your life with gratitude. Real pleasure comes from taking action rather than wait passively.” Howes says.

So the next time you feel the urge to order and track something online, chew over it.

Some inventors have developed a face mask with a remote-controlled mouth. Many people, who thought it can effectively protect them    1    viruses, say someone    2    (wear) the mask could eat food without taking it off. And they say the mask could make a visit to a restaurant    3    many customers have dinners less risky. Users can pull something and create an opening in the front of the mask so that food can pass through.

The new masks would    6    (probable) sell from $0.85 to $2.85, more than the price of the simple, blue medical masks.
