Branches and twigs
Branches grow out from the trunk and have twigs at the tips. They also take water and minerals from the trunk to the leaves.

We need to make sure that we are using the forests and trees sustainably (可持续地) , and then they will be around us forever.
Luckily, every one of us can do something. Planting trees is an easy way to help. We can also live in a way that creates zero waste in our everyday lives. We just need to practise the “3 Rs”—Reduce, Reuse and Recycle!
Reduce
When we reduce the amount of products we use and buy, fewer trees are cut down to make new products. If we take care of the things that we already have, and repair them when they are broken, we don’t need to buy more.
Reuse
Every time we reuse an item, fewer replacement (代替) items are needed. This helps to protect important natural resources (自然资源) . It also reduces waste because fewer items are thrown away.
Recycle
When we recycle products like paper, we stop new trees from being cut down. About 1/3 of the wood from trees that are cut down is used to make paper and paper board.
If we can reduce, reuse and recycle, we can make that amount much smaller! By recycling and buying products with recycled material, we’re protecting our forests.
( ) 37. Which is not the way to create zero waste in our everyday lives
A. Reduce. B. Repair. C. Reuse. D. Recycle.
( ) 38. How can we practise “Reduce”
A. By planting as many trees as possible. B. By throwing away things we don’t want.
C. By cutting down as many trees as possible. D. By taking care of the things we have.
( ) 39. ________of wood from trees that are cut down is used to make paper and paper board.

( ) 40. Which of the following is TRUE
