Look at your classmates around you. You all wear the same uniform and similar sneakers. Do you want to stand out among them? A fashionable and useful backpack can be a great idea!
Backpacks are lightweight and easy to carry.
They are great tools for students. They help you to stay organized. You can keep school things, books and personal items like cell phones and keys neatly (整潔地). With a unique backpack, you can also stand out among your classmates.
Tourists also love backpacks. With convenient backpacks, backpackers can move freely from one place to another. Meanwhile, they can also free their hands to do other things like taking photos.
But in the very beginning backpacks were not what we see today.
It is thought that US hiker Dick Kelty invented the first modern backpack in 1951. He used nylon (尼龍) and aluminum tubing (鋁制管型材料) to make backpacks lightweight. Then he added shoulder straps (帶子) and waist straps to transfer(轉移) much of the weight to the hips (臀部).
Today, backpacks come in different styles.
Rolling (滾動的) backpacks have wheels on the bottom. Users can pull them along the ground if they are too heavy to carry on their shoulders.
And with more people bringing laptops to school and work, backpacks also offer space for lightweight electronics.

Look at the plant in the picture. It looks beautiful, right? Can you imagine (想象) it kills?

The Venus flytrap is a kindof meat-eating plant. It grows in very few places, like wetlands near the sea in North Carolina in America.
The Venus flytrap is not a large plant. It grows to be only about a foot tall. The plant has white flowers in the spring, but it is the plant’s leaves that make it so interesting. The ends of the leaves have folding parts with stiff, tiny hairs (帶小硬刺的可折疊部分). These are the plant’s “traps (捕捉器)”.
What does the Venus flytrap eat? As you might guess, the Venus flytrap eats flies (蒼蠅). It also eats spiders, ants and crickets (蟋蟀). The Venus flytrap makes most of its food with sun, air and water, just like other plants. Living things just give it extra nutrition (額外營養(yǎng)) to grow well in wetlands.
How does this plant trap and eat living things? The Venus flytrap uses a sweet liquid (液體) to attract its food. When a fly lands on one of the plant’s open traps, hairs on the surface make the trap close. And when the trap closes, the fly is dinner!
If you want to have your own Venus flytrap at home, you have to buy the plant from a special place. You can’t take a Venus flytrap from where it grows! There are laws about taking it out of the wild.
小題1:Where does the Venus flytrap grow?
A．In the wetlands.B．In the desert. C．In the rocks.D．In the sea.
小題2:About the Venus flytrap, which of the following is true?
A．It is a large plant.
B．It only eats spiders.
C．It has white flowers.
D．It can fly in the sky.
小題3:Which is the right order of the following events in Paragraph 5?
a. The trap of the Venus flytrap closes.
b. A fly lands on one of the plant’s open traps.
c. The fly is kept in the trap as the food of the plant.
d. The Venus flytrap uses a sweet liquid to attract its food.
A．d-b-a-cB．a(chǎn)-b-c-d
C．b-d-a-cD．d-b-c-a
小題4:How can people get a Venus flytrap?
A．They can get it from where it grows.
B．They can buy it from a special place.
C．They can grow it in their gardens.
D．They can buy it in a park.
小題5:Why does the Venus flytrap kill?
A．Because it needs extra nutrition.
B．Because it hates flies.
C．Because insects are its main food.
D．Because it kills for fun.
