Special homework was given to the students in Grade Four at a primary school in Foshan, Guangdong this April, that is to say the children must11100 million grains(颗粒) of rice. A maths teacher Miss Chang asked her students to2the homework in two days. If some .students3to finish in time, they would go on counting the, rice at the weekend. Some parents thought: that if it took a4to count .three grains, if would fake more than a year to count 100 million grains of rice.

    5, others thought it was a good idea. A parent surnamed, (姓) Lin said it could,6 students to use their brains. “I will7my daughter to count 100 or 1,000 grains of rice first, and then8them and multiply (乘以) the figure to, reach 100 million grains of rice, So she will have a clear9of the number 100 million," she said. "The special homework could10help develop children's patience," Lin added.

    Some Internet users also praised the special: homework for encouraging children to11 new ways to do their homework.

    Miss Chang said earlier this week that she hoped the, students could learn knowledge12practical activities. She said she was13 that 10 of her more than 40 students had finished the special homework by using cups or other14to count the rice. The homework helps students develop their abilities to15problems. It's good for them.

    Today more and more children wear glasses before going to middle school. They keep their eyes watching TV or playing computer games for a long time. Eyes are the windows of our hearts (心). We use our eyes to see everything around us, so we should know how to protect our eyes.

    Love our eyes. When we open (睁开) our eyes every day, we can see the lovely friends and parents, beautiful flowers and green trees. If our eyes don't work, how can we see the world. In our eyes, everything and everywhere is dark. It's like a house with no light (光). How important our eyes are!

    Relax our eyes. First, stop to relax 30 minutes when using the computer for an hour or two. Next, remember to do eye exercises every day. Then, looking at green trees also helps a lot. In these ways, our eyes will feel relaxed.

    Have good habits. When writing homework and reading, it is important to keep a distance (距离) of 30 cm between your eyes and books. Remember to use our eyes in a right way. Don't read in bed or on a moving bus. Eat something healthy for eyes, such as carrots, fish and eggs.

    Follow my advice (建议) and get good habits. It's time to say goodbye to thick (厚的) glasses.

You will probably know the feeling—it is time for school, but your eyes are only half-open. Your arms and legs are heavy and your brain is still asleep. So what can you do to stay awake when you are tired? {#blank#}1{#/blank#} 

Eat breakfast

Breakfast is the most important meal of the day, but it is also the easiest to skip（省略）. Start your day off with a healthy breakfast. {#blank#}2{#/blank#} They can keep you from feeling hungry and tired in the morning. 

Use water

When you are tired, water is your friend. {#blank#}3{#/blank#} It is even better than drinking lots of coffee. Coffee is fine in the morning, but it is best to drink water after lunch to make sure you can get to sleep. 

Get moving

 {#blank#}4{#/blank#} A few minutes of physical activity can improve oxygen circulation（氧循环）and keep your body active. It doesn't need to be anything difficult. A few push-ups and a short walk may be a great help. 

However, there is still something that you can't do when you are tired. {#blank#}5{#/blank#} Besides, if you find you are often feeling tired and you are not sure why, it is a good idea to speak to a doctor. 

Children all around the world love Lego bricks(乐高积木). With those bricks, they can make anything they want. Lego bricks are a great toy(玩具) to play with. Now, for the first time, Lego makes Braille Bricks in English and French, making them a useful toy for blind(失明的) children. 

Lego Braille Bricks have dots (小圆点) on them. The dots are Braille. By feeling (感受) them, blind children can read words and numbers. They can also learn Braille when playing with the bricks. It makes learning easy and fun. 

Olivia is a blind girl, and she learns Braille when playing with the Lego bricks at her school. She loves to play with them and learn Braille at the same time. Her mother also plays with her at home and now she also knows Braille. 

Reece, a little boy, uses the Lego bricks to teach his family Braille. Now, his mother and sister know Braille as well. He says, "I feel so good. Because my loved ones learn something new and I am their teacher. So cool!"

Lego makes its colourful bricks useful. Let's thank it for bringing a new way of playing and learning!

Zhou Dao's grandfather has a hearing problem. During a family party last year, Zhou Dao noticed something. His grandfather sat quietly by himself. The old man was unable to join the talks.

Zhou Dao was sad about this. "Grandpa always reads subtitles (字幕) to watch TV," he thought. "Why can't we put words on our talks?" Then, Zhou Dao began working on that idea. He spent about half a year developing a kind of smart glasses. These smart glasses help users "read" spoken words.

The glasses are connected to a smartphone. There is a microphone on the glasses. It records audio (录制音频) and sends it to the phone. A piece of software turns the audio into words. People can see the words on the glasses.

This allows users with hearing problems to understand others during the talks well. Now Zhou Dao's grandfather can wear the glasses and speak to someone else face to face or over the phone.

Zhou Dao was happy to help his grandfather. Slowly, more and more people in need can wear this kind of glasses.
