【推荐1】What time of day do you feel most alert(清醒的)? Are you more of a morning person? Or does your brain need a few hours to get going? A lot of research suggests that we should pay attention to our body clock. It can tell us what time of day we are best able to perform, according to the Wall Street Journal.
When it comes to the human brain, many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you wake up can help speed this up.
But everyone’s body clock is different. Morning people will rise early and work better early in the day. Evening people will wake later but their brain will work better toward the end of the day.
Research show that we’re better at some activities at certain times of the day. Physical performance is at its best between 3pm and 6pm, so it’s better to exercise later in the day.
Between noon and 4 pm, people begin to get distracted (思想不集中的). This is partly because our brain becomes less alert after we eat a big meal. Research also shows that we become sleepy around 2 pm.
Finally, it is best to eat during our active periods. This allows our body to burn calories better and stops our blood sugar levels from getting too high.

Pigs are very friendly animals. Some people raise(饲养)them as pets. Of course, people raise the small kind, not the big kind. Small pigs are very cute. And they don’t break things in the house. Big pigs usually live outside on the farm, not in people’s homes.

As an old Chinese saying goes, Spring Festival comes right after the Laba Festival, so get ready for a bowl of porridge while looking forward to the long-awaited family get-together.
Today, people across China are celebrating the Laba Festival. It is a traditional Chinese festival. It’s on the eighth day of the 12th lunar month. What does this festival mean to Chinese people? OK, it just tells people to prepare for celebrating the coming New Year’s Day and for wanderers to return home to get together with their family.
Long long ago, Laba Festival was a day of thanks for a good harvest. On this day, people usually eat Laba porridge, a porridge with eight kinds of mixed grains. Many temples today have the tradition of giving out Laba porridge to the public. The sweet, red porridge is believed to bring luck and joy.
The festival is also the day for people to put garlic in vinegar. The garlic turns green, and this Laba garlic will be eaten with dumplings on Chinese New Year’s Day. While in the past, it was used to let people remember to pay back the money they had borrowed, as Laba is near the end of the year and “garlic” (suan, “蒜” in Chinese) sounds the same as “calculate” (suan “算”).
Customs are quite different across the country. People in Qianxian, east China’s Anhui Province, will eat the Laba tofu a few days before. In Xining City, northwest China’s Qinghai Province, people will eat porridge with beef and mutton.
