1 . While it's not impossible for birds to fly in the rain, they usually choose not to. You may see birds fly for a few seconds in poor weather, but most of them prefer to stay put on rainy days.
Why does rain make it harder for birds to fly? You might imagine that moving through the air while being pelted by raindrops would be pretty unpleasant. However, it's not the rain itself that makes flying difficult. Instead, birds are influenced by the drop in the air pressure that comes with most rainstorms. When pressure drops, the air is less thick, which makes it harder for birds to fly. Moving through the sky in areas of low air pressure takes a lot of energy.
Most birds need to eat several times a day—rain or no rain. Luckily, most birds' feathers（羽毛）are highly waterproof（防水的）, protecting the skin beneath. Many birds can also make oil that they can spread over their feathers to further protect themselves from the rain. Most birds don't like rain. In fact, in a 2010 study, a team of researchers studied birds living in a Costa Rican rainforest. They found that the birds had higher levels of stress hormone（应激激素）on rainy days. That may not surprise you. After all, many animals feel stressed out during storms. Pet owners often find that rain and thunder make their animals nervous. Some animals are so strongly influenced by nature that they almost seem to forecast the future.
No one really knows how many birds die during a storm or series of storms. But the number is certainly higher than usual. They fly into trees or windows; they get lost over the ocean or a large lake; their food sources are made more difficult to get but, at the same time, they need more food to get warm. However, if rain continues for some time, birds will have to challenge the storm.

2 . A survey said the average Asian dad spent one minute a day with his children. I was shocked. I mean, a whole minute? Every day? Get real. Once a week maybe. The fact is, many Asian males are terrible at kid—related things. In fact, I am one of them.
Child—rearing (养育) doesn’t come naturally to guys. My mother knew the names of our teachers, best friends and crushes. My dad was only vaguely aware there were short people sharing the apartment. My mother bought healthy fresh food at the market every day. My dad would only go shopping when there was nothing in the fridge except a jar of capers and a bay leaf. Then he’d buy beer. My mother always knew the right questions to ask our teachers. My dad would ask my English teacher if she could get us a discount on school fees. My mother served kid food to kids. My dad added chili sauce to everything, including our baby food.
The truth is, mothers have superpowers. My son fell off a wall once and hurt himself all over. I demanded someone bring me a computer so I could google what to do. My wife ignored me and did some sort of chanting phrase such as “Mummy kiss it better,” and cured l7 separate injuries in less than 15 seconds.
Yes, mothers are incredible people, but they are not always right. Yet honesty forces me to record the fact that mothers only know best 99.99 percent of the time.Here are some famous slip-ups.
The mother of Bill Gates: “If you’re going to drop out of college and hang out with your nerdy friends, don’t come running to me when you find yourself penniless.” The mother of Albert Einstein: “When you grow up, you’ll find that sitting around thinking about the nature of time and space won’t pay the grocery bills.” The mother of George W. Bush: “You’ll never be like your dad, who became President of the United States and started his own war.”

3 . I received a private message on Facebook. It began harmlessly enough: “Hey, girl. Wanted to invite you to join my next challenge group—we’ll be focusing on fitting in 30 minutes of exercise and balanced nutrition.”
It was all becoming too much. Facebook was running my life, not me.
But what killed Facebook for me was when I posted a photo, and five minutes later my son asked me how many “likes” it had got. His question was a wake-up call.
“Likes” are signs of acceptance and approval. I had forgotten that acceptance and approval need to come from within and had unknowingly set him a bad example.
Before Facebook, surfing the internet was an occasional distraction and I spent a lot more time reading books and magazines. I checked in with friends through texts, emails and phone calls.
To recreate the simplicity of those days and set a healthier example to my son, I deactivated my Facebook account.
I’d been in the habit of checking Facebook many times a day, so I had to come up with some new habits. I carried a novel and a crossword puzzle book around with me. I rediscovered knitting. I started taking yoga classes.
I started to remember a few things. My body is fine just the way it is. I have friends who will help me out when I’m in trouble, and I will help them out. I do my best to be a good mother, and our son is happy and healthy. We are very lucky to be able to afford two vacations a year.
I stopped looking at the world through my cellphone. I felt completely present in the moment.
The break left me feeling better about myself, my family, my home and my life.
After a few weeks, I returned to Facebook. Now I look at the photos of my friends’ kids growing up and treasure how social media allows me to keep in touch with family far and wide. I look in on a daily basis, but no longer with the desire constantly to post updates.
It is not an addiction any more.
