Electronic media such as email, instant messaging, video games, and television, has influenced almost every aspect of our daily lives.
Screen time becomes a particularly important issue when discussing children’s use of media. Experts now recommend children’s screen time should be limited to no more than 2 hours per day, including television and non—school related computer usage.
Unfortunately, it appears that this recommendation is not followed in most families. One recent study found that children between the ages of 8 and 18 spend nearly 45 hours per week watching television, playing video games, and surfing the Internet.
It’s important to serve as a model of healthy electronics use for your children.
| A．Most children know more about electronics than adults do. |

| C．Parents should think of ways to manage their children’s screen time. |

【推荐2】Online shopping has changed retail (零售) forever. Most of us wouldn’t know what to do without it. But the e-commerce revolution seems to have missed an industry—groceries. Why aren’t we making our most important shopping trip easier?
The issue isn’t so much that grocers don’t want to be creative. Until recently, many grocers couldn’t afford the technology to support an e-commerce platform. But times are changing, and stores are adapting to meet increasing customer needs by adopting a unified commerce approach.
Grocery shopping is a tiring process and one that most people prefer to do as quickly as possible. However, the current state of online grocery shopping is not quite user-friendly. Maybe it’s because consumers like to touch and feel the fresh produce they’re purchasing. Maybe it’s because grocery e-commerce lacks features that clothing and other industries’ websites have—such as the ability to identify the closest store, an accurate inventory (库存), and the ability to manage large basket sizes.
E-commerce platforms can be expensive and hard to set up for grocers, but the industry is changing, and grocers need to get ready to stay competitive. The key to any successful shopping experience is a 360-view of the customer. Grocers need to invest in solutions that can gather customer information from multiple sales channels, online and off, and bring it together into one platform. Retailers should be trying their best to make shopping possible on different devices—simplifying the journey to help shoppers find what they need more easily.
Part of the reason that unified grocery commerce hasn’t taken off just yet is the fact that stores are not set up to serve different types of shoppers at once. Who is responsible for handling online orders? Should store associates put in-store shoppers or online ones first? It can get confusing for employees and customers alike. There is also the cost associated with adopting new technology in-store, such as creating apps to scan products, the ability to find the right shelf using the product locator and more.
According to Salesforce, the average retailer uses 39 different systems to manage the customer relationship. The key will be finding a way to combine these systems and analyze customer data to best serve customer needs.

Scientists recently tested that idea in a study involving 24,000 people. Participants had to try to get a message forwarded to one of 18 randomly chosen people. Each participant started by sending one e-mail to someone they knew. Recipients could then forward the e-mail once to someone they knew, and so on.
Targets, who were randomly assigned by researchers from Columbia University in New York, lived in 13 countries. They included an Australian police officer, a Norwegian veterinarian, and a college professor.
Out of 24,000 chains, only 384 reached their goal. The rest petered out, usually because one of the recipients was either too busy to forward the message or thought it was junk mail.
The links that reached their goal made it in an average of 4.05 e-mails. Based on the lengths of the failed chains, the researchers estimated that two strangers could generally make contact in five to seven e-mails.
The most successful chains relied on casual acquaintances rather than close friends. That's because your close friends know each other whereas your acquaintances tend to know people you don't know. The phenomenon, known as the strength of weak ties, explains why people tend to get jobs through people they know casually but aren't that close to.
So, start networking and instant messaging now. As they say in show business: It's all about who you know.
