Injuries and deaths caused by driving after drinking are preventable. Sadly, actions by the police can only catch a small number of drunk drivers on the roads. It is up to each person to make the decisions. 1. So we should help guide our friends and persuade them to avoid driving after drinking. Here are some tips.
Start talking to the person early. With every drink, judgment becomes increasingly uncontrolled. 2. So as soon as your friend starts drinking, you should try to persuade him to make a plan to get home safely. Remember, after he gets drunk, he may not listen to you.
Help the person realize he is drunk. Talk to him and show him that he is increasingly clumsy. 3. For example, ask who you can call to pick him up, or what public transport he would like to use. If he knows he is drunk, he may follow your advice.
Make last efforts. If all else fails and a drunk person wants to drive home, threaten to call the police or take his keys. 4. When he is not concentrated, take his keys. This may make it easier to convince him to take a cab home. Remember, don’t give him the keys even if he’s angry.
5. If you once drove home after you got drunk, your friend may not listen to you. So in order to succeed in persuading your friend to avoid driving after drinking, you should behave yourself first.
A. Ask him where his keys are.
B. Set a good role model.
C. Give him an alternative way to get home.
D. But it isn’t easy to make the right decisions.
E. Make him realize drinking makes him look like a fool.
F. The police will come to help you out once you call them.
G. It means the more one drinks, the less likely that he will listen to you.
Sunscreens (防晒霜) can offer protection from two types of ultraviolet (UV) rays (紫外线): UVB, which according to the Skin Cancer Foundation, are the chief cause of sunburn and play a key role in the development of skin cancer, and UVA, which get through the skin more deeply and are largely responsible for skin aging and wrinkling, as well as skin cancer risk. The SPF (防晒指数) measurement on sunscreens refers to the UVB protection level — and the number may not mean what you think it does. SPF 15 doesn’t protect you from 15% of UVB rays, just as SPF 100 doesn’t protect you from 100% of the rays. In fact, as you get into the higher numbered SPF sunscreens (think: 50 and above), the difference in UVB protection is actually pretty small.
Theoretically, though the increase in UVB protection with a super-high SPF sunscreen may be not worth considering, it may help, and certainly can’t hurt, to use it — that is, as long as you do so correctly. “The only downside is whether you’re giving yourself a sense of false security,” Dr. Gohara says.
Indeed, as Dr. Wang also pointed out, when people choose increased SPFs, they may actually feel so protected by the product that they finally ignore proper sun protection. “When people use really high SPF products, they tend not to reuse, they tend to stay out in the sun much longer, and they don’t use other protective measures such as clothing and hats,” he says. Regardless of any increase in protection that a high SPF may or may not offer, one thing is certain: It doesn’t give your body a free pass from sunburns, aging, or cancers, and it doesn’t protect you from those things for any greater length of time than the lower SPF options. Both Dr. Wang and Dr. Gohara emphasized that, no matter what the SPF is, it’s important to reapply your sunscreen every two hours.

You use her as a shoulder to cry on. She texts you back with casual jokes. But she, Xiaoice, is only a virtual chatbot（虚拟聊天机器人）.
Xiaoice, Microsoft’s latest artificial intelligence robot, was briefly released in 2014, and returned to WeChat in 2015, where she became a big hit. Millions of young Chinese now exchange messages with her daily, The New York Times reported. On WeChat, Xiaoice is an official account. After following it, users can start text-based conversations with Xiaoice.
“Her incredible learning ability was why people loved to talk with Xiaoice,” Liu Jinchang, a researcher at High-tech Research and Development Center under the Ministry of Science and Technology, told China Daily. Apart from her ability to identify photos and send emojis（表情符号） in conversations, Xiaoice gains 45 percent of her knowledge from interacting with users, China Daily reported.
Chatbot programs first appeared in the mid-1960s in the US. Driven by top tech companies, they are becoming smarter and more common. For instance, IBM’s latest artificial intelligence program served as an academic consultant at Australia’s Deakin University, answering students’ questions about course schedules and financial aid. Apple’s Siri and Amazon’s Alexa have been used as voice assistants who can read news, play music and even make jokes for their users.
These programs are expected to move beyond smartphones, into televisions, cars and living rooms, The New York Times pointed out. However, it may take decades before scientists develop a “Samantha”, the advanced chatbot seen in the fiction film Her. In the film, Samantha has a romantic relationship with her user played by US actor Joaquin Phoenix. Many viewers were enthusiastic about this fantasy of virtual soul mates.
