【题目】 The skin under the eyes is delicate, which is why it sometimes appears sunken and has darker coloring than elsewhere on the face. Aging and health problems play a role in sunken eyes but other factors can contribute too, so it may affect younger people as well.

Dehydration

The most common cause of sunken eyes is dehydration, or not having enough water in the body. Consuming too much coffee, soda, and prepackaged drinks may increase production of urine, which may lead to dehydration.

Vitamin shortages

Shortages of vitamin C, vitamin K, and iron can cause eyes to become sunken. Vitamin C helps with absorbing iron and decreasing bruising, while vitamin K is responsible for blood thickening, the lack of which may cause unhealthy skin. Easy bruising and unhealthy skin will result in sunken eyes.

Weight loss

Most people tend to lose weight in their face first. Sometimes, the weight loss is sudden enough to make blood vessels below the eyes easy to see, and the skin clear, producing the appearance of sunken eyes. Sudden weight loss may also cause nutritional shortages, which can lead to sunken eyes.

Not enough sleep or poor-quality sleep can cause sunken eyes and a person’s DNA or the habit of smoking can also contribute to sunken eyes. Most cases of sunken eyes relate to the quality of an individual’s nutrition and healthy living. When these causes are corrected, sunken eyes can be resolved without further treatment. This means that causes can be avoided or treated in good time to prevent the recurrence of sunken eyes.

【1】What can we do to prevent dehydration according to the text?

A.Have certain drinks less.B.Refuse coffee.

C.Drink more water.D.Say no to soft drinks.

【2】What will lead to bruising below the eyes?

A.Lack of vitamin K.B.Water shortages.

C.Lack of vitamin C.D.Nutritional shortages.

【3】Which of the following should be avoided for people losing weight?

A.Pale faces.B.Sudden weight loss.

【题目】 Getting a high grade in an exam depends partly on how much you can remember. So, improving memory is essential to success in studying. But is there anything that we can do about it? One solution might be walking backwards.

According to a new study published in the Journal of Cognition, walking backwards, whether doing it really or just imagining it, can boost (增强) the brainpower in the short term.

In the study, 114 volunteers were asked to watch a video in which a woman had her bag stolen. Then they answered 20 questions about the details shown in the video. Ten minutes after watching the video, the volunteers were divided into three groups. The first two groups were told to move forwards or backwards 10 meters while the third group was asked to stay still on the same point. The researchers found that the backwards-walking group got two more correct answers on average than the other two groups. This suggests that a relationship between the concepts (概念) of time and space is essential to the way our minds form memories.

When we walk backwards, everything we learn becomes strange to us. "This forces the brain to think in a different way—it's a rewiring and changes the focus," US neuropsychologist (神经心理学家) Christine Weber told Forbes. It almost always means that our brain needs to be more active and alert in the limited time. Naturally, our short-term memory will be improved significantly.

Apart from improving our memory, walking backwards also plays an important role in physical health, especially fitness. A study published in Journal of Biomechanics in 2012 found that backward walking puts less strain and requires a smaller range of movements from the knee joints (膝关节). Thus, there's less pressure and pain in the knees.

In addition, walking backwards, compared to forward walking, is more challenging. It requires you to use muscles and movements that you probably rarely use, making it a perfect way to change your exercise routine for greater fitness gains. Meanwhile, by making people put in extra effort, it naturally burns more fat and calories.

【1】Which group of people perform best in the memory test?

A.The staying-still group.B.The forwards-walking group.

C.The imaginary-walking group.D.The backwards-walking group.

【2】In what way does walking backwards benefit people's health?

A.It can make people slim.B.It can reduce peopled stress.

C.It can strengthen people's joints.D.It can make people more energetic.

【3】What do we know about backward walking?

A.It follows our exercise routine.

B.It limits people's thinking time.

C.It directs our focus to important details.

D.It makes people's brain more active and alert.

【4】What's the writer's purpose in writing paragraph 4?

A.To add another aspect of the topic.

B.To support the result of the research.

C.To sum up the main idea of the passage.

D.To provide some background information.

【题目】 The time-out (暂停)is a method to punish your children's misbehavior (不当行为).Children are taken away from their present situation for a few minutes. During the time-out they are put in a place and not allowed to do anything. It's a great way to help your children calm down and realize their shortcomings. 【1】.

Decide what is worth a time-out

Find a quiet moment to discuss a time-out principle for your family, determining where you'll give time-outs, for what reasons, and for how long. 【2】. And you can make your first time-out feel prepared and calm.

Give a warning

Instead of suddenly giving a time-out to your children, warn them that they'll get one if they continue to be naughty. 【3】. At this age children are often angry without realizing it.

Giving them a time-out can make them calm. Some kids dislike time-outs very much, so that finally the warning itself does the job. However, warnings are not enough. When your children hit, kick, or bite someone, use a time-out right away.

【4】

It's a good idea to choose a time-out place, such as a chair or the end of a hallway. But remember that the place you choose needs to be safe and shouldn't be frightening.

Decide how long time-outs will last

【5】. Your children should have enough time to stop misbehaving and calm down. If it is too short or too long, your children may forget the punishment or become upset. Many experts advise one minute per year of your children's age. You can watch the clock yourself or set an alarm clock and tell them that the punishment is over when it rings.

A. Select a place

B. Use time-out regularly

C. A time-out needs enough time

D. You needn't make decisions in a hurry

E. Here are a few ways to make it work for you

F. Give your children hugs and kisses after the time-out

G. This gives them a chance to control their own behavior first
