She went outside, picked some wildflowers, and placed them 3 the new vases. At once, her room was filled with fresh and natural beauty. Next, with some tools, she punched holes in cans to create patterns (图案). After placing a tiny candle inside each can, she hung 4 on the porch (门厅). When the sun went 5 , the candles were lit (点亮). Then the soft and warm light made the porch look so lovely. Finally, Lily turned her attention to the old 6 . She cut them into small even pieces and then patiently sewed (缝) them together.

Deciding whether a product is green, however, 1 (be) not always easy. Here is what we may keep in mind. The materials of a product are usually our 2 (one) focus (关注). Green products are made of more natural materials which are free from harmful chemicals, so they can be good 3 our physical health. Packaging is important. We’d better choose glass, metal and paper packaging, as we can reuse or more 4 (easy) recycle them. We can also look for less packaging or even choose unbagged products whenever possible. The location (地点) is also important. Try to choose local products. When it comes to food, it is 5 good idea to order directly from local farmers, shop at markets and buy fruits in season. Buying from stores near our houses is also a good choice, 6 we can go there without driving a car. Look into what the companies (公司) tell us about 7 (they) products. It’s easy to say that a product is “green” or “all natural”, but the 8 (word) may be too good to be true. After all, companies try to make us believe that their products are environmentally friendly. The greenest thing is certainly the one we don’t buy. Things like food and clothing are necessary for life, but many others are not. 9 (good) than buying is choosing to leave an unnecessary product in the store. It sends a message to the producer, keeps money in our pockets, 10 (reduce) waste and keeps the planet healthy. $$
