I took my son to a popular restaurant for a lunchtime treat. And it seems everyone else had the same 1. The place was full of 2!
I drove around the small parking lot (停车场) for 10 minutes 3 a spot (位置). Finally I 4 one. A lady was returning to her car so I 5 her and waited patiently. As I did this I looked in my rear vision mirror (后视镜) and 6 a young man quickly pull up behind me. As soon as he saw my indicator (转向灯) on for the spot, he seemed very 7 and began hitting his steering wheel (方向盘). I knew this wasn't directed at me but at the disappointment that he had 8 a spot. I felt his 9. I too had been 10 the place for ages.
As the lady left I 11 something that surprised even me. I turned off my indicator and drove straight past. I let the man 12 the spot.
The man behind me was 13, unsure what to do. 14 I lowered my window and gave him a(n) 15 to take it, calling out at the same time "It's yours."
I 16 driving further down the road to another car park, where although I had to walk quite a bit further, I was 17 I could. Perhaps the man couldn't walk easily as his 18 wasn't as good as mine? I will 19 know. But I knew the spot20 more to him than it did to me, when I saw him react the way he did.
Do you jump out of bed early, wide awake and ready to start your day? If so, you would be called an "early bird". Perhaps, you hate the sound of your alarm clock (闹钟) each morning and have little energy until afternoon. If so, you're probably a "night owl".
Most people can be divided into such two groups, but what makes us this way? And is one better than the other? There are different opinions.
Usually, early risers are praised as hardworking while those who prefer to get up late are considered lazy. Most people believe the early bird catches the worm.
Yet some scientists now believe "night owls" can really focus longer and produce more than early risers.
Research has found that the early bird does not always get the worm. In a Belgian study, both "morning people" and "evening people" were watched during their normal waking hours. After 10 hours of being awake, the "evening people" became more alert (机敏的). However, the "morning people" became sleepy and less focused. Researchers believe the reason for this difference is that "night owls" receive a lastminute increase from their brains. This added energy allows them to stay alert for longer periods of time.
Environment, lifestyle, activities and childhood routines all may have an effect on sleeping habits, yet genetics (遗传学) may play the biggest role.
It is possible to change your sleeping habits through regular bedtime, morning exercise and avoiding midnight snacks. But whether you're happy to rise early or to stay up late, you're probably doing what works best for your own personal body clock.
You can pick one you like.

Humans' invention of zero was vital for modern mathematics and science, but we're not the only species to consider" nothing" a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.
Honey bees are known to have some numerical (数字的) skills such as the ability to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bittertasting food.
Once the bees had learned to consistently make the correct choice, the researchers gave them a new choice: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose it rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that" zero" is less than two or three. And they weren't just going for the empty picture because it was new and interesting. Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.
In further experiments, the researchers showed that bees' understanding of zero was even more complex: for example, they were able to distinguish between one and zero—a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators (捕食者)and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.
In 2019 big companies like China Mobile and China Unicom will start to deliver 5G. According to the Verge, 4G was about speed and 5G will be about size of networks. These 5G networks will allow many more people to get information (quick) and much more of it. Speaking to CNET, analyst Dan Bieler said that in the United States, there will be" so much bandwidth (带宽) available that we will have pretty much unlimited access data". Due to the increased size of networks, data transfer will be much more (rely). The capacity (容量) will be large enough for everyone (chat) on social media and watch movies on the phone.
Experts say 5G (aid) the development of selfdriving cars and health and pollution sensors (传感器) as well. There is no doubt the infrastructure (基础设施) needed for 5G will be expensive. According to CNET, in the (follow) 12 years until 2030 the industry will be spending nearly $2. 5 trillion dollars worldwide. But if the smart, artificially intelligent world we read so much about is to become a (real), this is an investment that will have to (make).
