Are you carrying too much on your back at school? You're not alone. Back experts(专家) in the USA are worried about that young students are having back and neck problems because they are carrying too much in their backpacks .
“It hurts my back when I run,” said Ebelin Reyes, a student in Virginia. “It's hard to get up the stairs with my backpack because it's too heavy.” Students have to carry heavy backpacks on their backs for a whole week's study. Ebelin is one of them. They have regular(固定的)backpacks with two straps(带子) to carry them, but a number of students with heavy loads(负担) have switched to rolling backpacks. The backpacks have wheels and can roll on the ground. Shirley Park's backpack weighs 10 kilos, and she said, “I'll change to a rolling backpack because I am starting to have back pain.”
How much is too much? Experts say that students should carry no more than 10% to 15% of their own body weight. A few students have had a good idea to lighten(减轻) the load: less homework.
Doctor's suggestions:
Lighten the load. Take home only the books the students need that day.
(2) Wide straps are better. They can send out weight over your shoulders (肩)and be sure to wear backpacks with two straps.
(3) The heaviest things should be packed closest to the back.
(4) Bend(弯曲) both knees when you pick up the pack, don't just bend over the waist(腰).

(1)、The main idea of the passage is about _______.

A、the problems made by rolling backpacks B、the advantage of backpacks C、the best backpacks for students D、how to lighten students' backpacks
(2)、From what Ebelin Reyes and Shirley Park said, we know______.

A、students like to carry heavy backpacks B、students have to do a lot of homework C、backpacks with wheels are bad for students D、students have no time to play because of heavy backpacks
(3)、The underlined word “switch to” means______.

A、use for B、turn to C、catch up D、begin to use
(4)、According to the experts, it's better for a student of 40 kilos to carry a backpack of ____ at most.

A、10 kilos B、8 kilos C、6 kilos D、7 kilos
(5)、If students follow the doctor's suggestions, they______.

A、may do less homework B、may feel their backpacks are lighter C、can learn how to enjoy themselves D、will know why to wear heavy backpacks

World Music Day is celebrated on June 21st every year. It originated (起源) in France. In 1981, the French Minister of Culture Jack Lang came up with this idea. In 1982, The first World Music Day took place in Paris and since then, it has become an annual (一年一次的) celebration for the whole world's music. On the first World Music Day, people of all ages and backgrounds got together and enjoyed music.

We love World Music Day for many reasons. It provides us with a great chance to learn about different music styles and express our creative ideas freely. We can write about our favorite songs or make art inspired by the music we've been listening to. On World Music Day, we should celebrate all the great things in life. We can talk about world peace, love and so on.

World Music Day is celebrated in many different ways. There are often free concerts and events held on this day. People like listening to different types of music because it can open their mind to new things. Maybe there is an event nearby where people are singing or playing music from their country. You can talk about what you heard and learn something new!
