ir own screen use. “Tech is designed to really suck on you in,” says Jenny Radesky in her study of digital play, “and digital products are there to promote maximal engagement. It makes it hard to disengage, and leads to a lot of bleed-over into the family routine. ”

Radesky has studied the use of mobile phones and tablets at mealtimes by giving mother-child pairs a food-testing exercise. She found that mothers who sued devices during the exercise started 20 percent fewer verbal and 39 percent fewer nonverbal interactions with their children. During a separate observation, she saw that phones became a source of tension in the family. Parents would be looking at their emails while the children would be making excited bids for their attention.

Infants are wired to look at parents’ faces to try to understand their world, and if those faces are blank and unresponsive—as they often are when absorbed in a device—it can be extremely disconcerting foe the children. Radesky cites the “still face experiment” devised by developmental psychologist Ed Tronick in the 1970s. In it, a mother is asked to interact with her child in a normal way before putting on a blank expression and not giving them any visual social feedback; The child becomes increasingly distressed as she tries to capture her mother’s attention. “Parents don’t have to be exquisitely parents at all times, but there needs to be a balance and parents need to be responsive and sensitive to a child’s verbal or nonverbal expressions of an emotional need,” says Radesky.

On the other hand, Tronick himself is concerned that the worries about kids’ use of screens are born out of an “oppressive ideology that demands that parents should always be interacting” with their children: “It’s based on a somewhat fantasized, very white, very upper-middle-class ideology that says if you’re failing to expose your child to 30,000 words you are neglecting them.” Tronick believes that just because a child isn’t learning from the screen doesn’t mean there’s no value to it—particularly if it gives parents time to have a shower, do housework or simply have a break from their child. Parents, he says, can get a lot out of using their devices to speak to a friend or get some work out of the way. This can make them feel happier, which lets then be more available to their child the rest of the time.

Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage.

Please mark the corresponding letter for each item with a single line through the center. You may not use any of the words in the bank more than once.

Each man had to wear socks soaked with red ink and walk on white paper fixed【C2】______ to the floor. The【C3】______ showed that all walked in a winding rather than a straight line. Researchers found that people【C4】______ their direction of walking regularly. However, the range differed from subject to subject.

This suggests that none of us can walk in a【C5】______ straight line. Rather, we meander (漫步), mainly due to a slight structural or functional【C6】______ of our legs. So steps by the left and right legs of a person are【C7】______ .

As a result, although we may start walking in a straight line, several steps afterwards we have changed direction. However,【C8】______ helps us to correct the direction of walking and leads us to the target.

Your ears also help you walk. After turning around a lot with your eyes closed, you can hardly stand still,【C9】______ to say, walk straight. It's all because your ears are still spinning and can't help you keep your balance. Your inner ear is a structure containing liquids. When you spin, the liquid inside follow your spinning, but when Stop, the liquid continues to spin for a while, the result of which is【C10】______ . For the moment, although your eyesight tells you to walk in a straight line your brain listens to your spinning ears, thus you don't walk as what your eyes tell.
