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.

C. Samantha is played by a US actor in the film.
D. The film Her doesn't interest many audience.
Walt had a strong commercial sense of what would appeal to the public. Disneyland, Walt Disney World, and finally the other Disney theme parks around the world all came about because Walt Disney insisted that he could build an amusement park that was so much bigger and better than other amusement parks that it shouldn’t even be called an amusement park.
In 1940 he disclosed a plan to show Disney characters in their fantasy surroundings at a park across the street from the Disney studio in Burbank.
The idea of an amusement park grew in Walt’s mind as he traveled through the US and Europe and visited attractions of all kinds. Walt was sure that an amusement park would be successful in the United States if it offered a “good show” that families could enjoy together, was clean, and had friendly employees.
In 1948 he shared his concept with trusted friends, a modest amusement park with a central village including a town hall, a small park, railroad station movie theater, and small stores. Outlying areas would include a carnival (联欢) area and a western village. Soon he added spaceship and submarine rides, a steamboat, and exhibit halls.
Four years later, he decided on “Disneyland” for the name and formed a company to develop the park, Disneyland, Inc.
In 1953 he got Stanford Research Institute to examine the economic future of Disneyland and to find the perfect location.
They broke ground in July, 1954, and one year later, Disneyland opened. Within 7 weeks, a million visitors had visited Disneyland, making it one of the biggest tourist attractions in the US.
Walt combined his talent and his sense of what the public would want with lots of hard work. In 1960, with a mixture of huge successes and failures, Disney had created something that was successful beyond Walt’s own dreams.
1.What did Walt Disney want to show in his plan?

B. Disney studio.
C. Disney characters.
D. Fantasy surroundings.
2.What would a successful amusement park be like in Walt’s opinion?

B. It could show fantastic programs.
C. It included attractions of all kinds.
D. It could make families satisfied.

a. It opened.
b. The perfect location was found.
c. They broke ground.
d. It proved to be a great success.
e. Its name was decided.
f. Walt shared its outline with his friends.
A. f,e,b,c,a,dB. e,b,c,a,d,f

Finding time to read is an important part of developing reading and writing skills for all kids. And there are many easy and convenient ways to make reading a part of each day — even when it's tough to find time to sit down with a book.
Car trips, waits in checkout lines and the doctor's office are all opportunities for reading. Keep books or magazines in your car, or backpack to pull out whenever you're going to be in one place for a while. Even if you can't finish a book, read a few pages or discuss some of the pictures.
Encourage kids to bring favorite books and magazines along wherever you go. While it's attractive to provide electronic games and readers, be sure to alternate electronic media with plenty of opportunities to read traditional print books.
Reading opportunities are everywhere you go. While riding in the car, for example, encourage kids to spot words and letters (on billboards, store signs, etc.), turning it into a game (“Who’ll be the first to find a letter B?”).
Even daily tasks like cooking can provide reading moments. Kids can assist you as you cook by telling you how much flour to measure. Give your child a catalogue to read while you sort through the mail. Ask relatives to send your child letters, e-mail, or text messages, and read them together. Help your child create letters or messages to send back to the relatives. These types of activities help kids see the purpose of reading and of print.
Even when you’re trying to get things done, you can encourage reading. While cleaning, for instance, you might ask your child to read a favorite book to you while you work.
Make sure kids get some time to spend quietly with books, even if it means cutting back on other activities, like watching TV or playing video games.
Most important, be a reader yourself. Kids who see their parents reading are likely to imitate them and become readers, too!

As is often the case, when people are attending to meetings, having meals or waiting for buses, you can always find them addicting to their phones, completely ignoring others.
This is really a commonly phenomenon in our life. The reason is why smart phones nowadays can be used for people to play mobile games and kept in touch with friends through QQ and WeChat. Therefore, too much exposure to phones are bad for people in terms of health. Moreover, people involved in phones fail to communicate well with these around them.
As far as I am concerned, people should wisely make use of their phones to help their work and study. Meanwhile, care much about their family and friends rather than mobile phones.
