If you're ever apart from your children, a new study says just talking on the phone will help just as much as a hug(拥抱).

If you're a parent who spends long hours on the job, you probably feel sorry for spending so much time away from your kids. But the results of a new study show that a mother's voice alone can be just as comforting to an anxious child as physical contact(接触).

In an experiment, researchers from the University of Wisconsin Madison asked a group of girls between the ages of 7 and 12 to solve math problems in front of judges—a stressful situation for anyone. Before the girls were set to give their answers, the researchers measured their levels of two hormones(荷尔蒙): cortisol, which goes up during stressful periods, and oxytocin, the "love" hormone, which goes down at the same time.

After the girls finished the problems, some of them got to meet up with their mothers right away. The moms came in and hugged the girls. Another group of the girls didn't see their mothers, but received phone calls from them, in which their mothers told them how well they'd done. The final group had no contact with their mothers, but instead watched an animal movie, March of the Penguins.

Finally, the girls' hormone levels were measured again. Although the movie was interesting, it did nothing to reduce the children's anxiety—but, surprisingly, both the physical contact and phone calls from their mothers had the same effect on reducing the girls' stress levels.

So, no matter how old you are, if you're feeling stressed about something in your life, a phone call to Mom might be just the key to help you feel better.

    If the eyes are the windows of the soul, then the body is the mirror of our feelings. If we are feeling great, we may give our body signals(信号). If we look at someone else's body, we can often tell how they are feeling by their body signals. So reading body language signals is a great tool in daily communication.
    In case(假使) you don't think that learning how to read and use body language is important, here are some numbers for you. 7% of the information we receive is from what people actually say, and 38% of the information we receive is from the tone(语气) and the speed of their voice; while 55% of the information we receive is from their body language.
    These non-verbal(非口头的) signals will help you a lot, but you still need to focus on what people are saying. If you focus too much on their body language signals, you and the person may feel uncomfortable. It is useful to be able to read people's body language, but it is useful to learn how to send the right signals and avoid the wrong signals too. Body language may be given several interpretations. Many signals have different meanings, depending on the person and the situation. Be sure of it when you are trying to read a body language signal.

Being safe in your everyday life needs knowledge. you remember the following information，your life will be much safer.
● Always notice the environment around you. You shouldn't walk alone outside late at night. Make sure where the public phones are. If anything dangerous happens，you can find them easily.
●Your bag should be carried towards the front of your body instead of putting it on your back。When a bus is full of people，it is easy enough for a thief to take away the things in the bag on your back.
●If you are followed by someone you don't know, cross the street and go to the other way, let the person understand that you know he or she is after you. Next，don't go home at once. You are safer in the street than you are alone in your home or in a lift.
●If you have to take a bus to a place far away, try to get to the stop a few minutes earlier before the bus leaves. On the bus，don't sit alone. Sit behind the driver or other people. Don't sleep.

    We live in the computer age. People use computers to do much of their work. But few people know how to look after them. Remember the following when you use your computer:
    ① Keep your computer in a cool ,dry room. Too much or too little heat is bad for computers. Damp (潮湿) is also bad for them.
    ② Do not let people smoke near your computer. Smoke of all kinds is very bad for many parts of a computer.
    ③ Do not eat or drink when you are near your computer. Pieces of food and a little water in the keyboard are also bad for a computer.

     How do you remember the way to your house? Where do dreams come from? It is your brain (大脑) that does these things. A British scientist showed that “sleep can improve one's memory.” It's not a dream for students to study when they sleep. In fact, your brain is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What's more, another scientist in the USA found that there was a “talent button (天才按钮)” in the human brain. It might make a person more talented.
    There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning (打哈欠) keeps our brains “cool”, which makes us think quicker.
     Here are some pieces of advice to keep a good brain:
     Eat healthy food.
     Get a lot of playtime or exercise.
     Don't drink or smoke.
     Use your brain a lot.

There is a lake near a forest in Sweden. The water in the lake is very clear and everything is quiet and still. On the far side of the water is some farmland and further away, across the field, is an old church built on a hill. It has just stopped raining. The brook(小溪) flowing into the lake is full and there is still some half-melted(半融化的) snow from last winter on the ground.

The reason the water is so clear, and everything is so quiet and still, is that most of the plant and animal life in and around the lake is dead. There are no birds because all the fish and insects, which the birds need for food, have disappeared. Many trees in the forest are losing their leaves and bark (树皮), and are sick and dying. Others were blown down by the high winds of last winter. A farmer is working in a field planting something, but unless he plants a stronger kind of seed this year, the crop will be between 25 to 40 percent lower than a few years ago. The stones of the old church tower are turning to powder and unless the tower is repaired soon, it will fall down.

All the death and destruction(破坏) in this place is caused by the smoke coming out of factories and poisonous gases from cars and trucks. And yet this silent lake is hundreds of meters aways from the nearest factory and highway.

阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。

There is great excitement and argument over Artificial Intelligence (AI). The argument about whether robots will replace teachers in the classroom is very heated Some people think it is sure to happen in the next ten years. Others think that the value a good teacher brings, not only to the classroom setting, but in developing a child's confidence and creativity outside lessons, cannot be easily replaced.

AI is not new for us and is already being used successfully in many fields, such as medicine, science and so on. So what does this mean for our future? In my view, AI will help kids to think more freely and creatively. Can AI possibly cut down the teaching work in the future? Of course. Our teachers are always busy preparing for their lessons. Just imagine how happy they will be if they don't have to correct hundreds of papers, but instead, have this task or others done by machines

However, most importantly, I do not believe AI will be able to imitate the human mental condition totally, especially emotional intelligence(情所 . What makes learning unforgettable is shared experience, the communication between people, and long- lasting positive relationships. For example, experienced teachers can comfort a student if he had a terrible experience. But no research shows that robots can imitate this well.

I also believe we need to develop our kids' personality and their ability not only to make decisions but also make the right decision. To achieve this, depending only on AI is impossible.

In short. AI has both its advantages and disadvantages. To what degree can teachers use AI in their classes? You can have all the information you want with the help of Al, but great teachers will also need to depend on their own feelings.
