    Ben Lecomte, a French long-distance swimmer, dropped into the water Tuesday at Choshi, Japan, and embarked on his attempt to become the first person to swim across the Pacific Ocean, BBC News reports.

    Six years in the planning, the 5,500-mile effort is expected to take five to six months, with Lecomte swimming eight hours a day and covering an average of 30 miles daily, according to his website.

    His route to San Francisco will take him through the Great Pacific Garbage Patch, an area three times the size of France where large amounts of garbage and plastic waste have collected, CNN reports.

    Lecomte will be accompanied by a specially outfitted support boat named Discoverer. He will take rest periods on the boat, but it will return him to his stopping point each day to make sure he swims the entire distance.

    In addition to accomplishing a first, Lecomte said, he wants to draw attention to the problems of ocean pollution and climate change. A team of scientists plan to conduct research for 12 scientific institutions, including NASA and the Woods Hole Oceanographic Institution, while he is making his swim.

    Lecomte is no stranger to feats of long-distance open-water swimming. In 1998, he swam 4,000 miles across the Atlantic Ocean. On that swim he encountered sharks and stingrays. This time, he said, he will be wearing a shark-repellent bracelet.

    One of the challenges will be making sure he has enough energy each day, and Lecomte said he intends to consume 8,000 calories daily.

请仔细阅读以下材料,并按照要求用英语写一篇150词左右的文章。

Scientists have observed that humans experience happiness from a wide range of stimuli(刺激), from traveling to an ideal destination to redecorating one's home or from winning a game of soccer to eating a delicious meal. Simply watching a favorite television show or laughing at a funny joke can lift a depressed mood. While the happiness produced by such experiences tends to be short lived, a wide social network does promote a more long-lasting state of happiness as a lifestyle.

 Surprisingly, income is not a primary factor in determining a person's level of happiness once the basic needs of food, clothing, and shelter have been met. More important is one's social network. Being socially active may be more effective in increasing one's immunity(免疫力)to illness than a vaccine. Misery may love company, but so does happiness, and having close friends and family is vital to one's overall level of happiness. Even sharing one's home with an animal companion can make a person happier.
