    【题目】How can you help kids cope with(应对) stress? Proper rest and good nutrition can boost coping skills, as can good parenting. Make time for your kids each day. Whether they need to talk or just be in the same room with you, make yourself available.

    Even as kids get older, quality time is important. It’s really hard for some people to come home after work, get down on the floor, and play with their kids or just talk to them about their day--especially if they've had a stressful day themselves. But expressing interest in your kids shows that they’re important to you.

    Help your children cope with stress by talking about what may be causing it. Together, you can come up with a few solutions. For example, they should cut back on after-school activities, spending more time talking with parents or teachers, developing an exercise plan or keeping a journal.

    You can also help by predicting stressful situations and preparing kids for them. For example, let a child know ahead of time ( but not too far ahead of time) that a doctor’s appointment is coming up and talk about what will happen there. Keep in mind, though, that younger kids probably won't need too much advance preparation. Too much information can cause more stress.

    Remember that some level of stress is normal; let kids know that it’s okay to feel angry, scared, lonely, or anxious and that other people share those feelings.

    When kids can’t or won’t discuss these issues, try talking about your own concerns. This shows that you’re willing to handle tough topics and are available to talk with them when they’re ready. If a child shows symptoms that concern you and is unwilling to talk, consult a counselor or other mental health experts.

    Most parents have the skills to deal with their kids’ stress. The time to seek professional attention is when any change in behavior persists, when stress is causing serious anxiety on when the behavior is causing significant problems in functioning at school or at home.

    【1】What is the purpose of the text?

    A. To share the author' s ideas on proper parenting.

    B. To persuade parents to spend more time with kids.

    C. To advise parents how to help kids deal with stress.

    D. To seek different ways to help solve kids' problems.

    【2】What makes it difficult for parents to spare kids quality time?

    A. Kids growing so fast.

    B. Parents being tired out.

    C. Kids losing interest in parents.

    D. There being too much homework.

    【3】You are advised not to talk too much about a stressful situation in advance because .

    A. it does no good to your kids

    B. it doesn’t work in practice

    C. your kids may lose interest

    D. your kids don’t want to listen

    【4】What can we learn from Paragraph 5 ?

    A. Normal people share the same feelings.

    B. It is normal for kids to have some stress.

    C. Kids should get rid of negative feelings.

    D. Everybody feels angry, scared, lonely or anxious.

    【题目】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.

    【1】What rays can cause skin cancer according to the text?

    A. UVB. UVAC. UVBD. UVA&UVB

    【2】What can we know about SPF from Paragraph 1?

    A. It tells us the UVB protection level.

    B. It’s better to use higher numbered SPF.

    C. SPA100 means preventing 100% rays.

    D. There’s a big difference between SPF 50 and above.

    【3】Which of the following can replace the underlined word “downside” in Paragraph 2?

    A. protectionB. disadvantage

    C. resultD. method

    【4】Why are we advised to reapply our sunscreen every two hours?

    A. We choose too low SPF products.

    B. The higher SPF can make us stay outside longer.

    C. Clothing and hats are not enough for sun protection.

    D. It can’t completely protect us from aging, sunburns or cancers.
