第一节 阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

Ever since she was a baby, Heather, aged 5, has watched her parents regularly turn off lights

that aren’t needed and put the day’s newspapers cans, bottles, jars, and other recyclables into a big, yellow bin — that is, if they can't find a second life for the discarded items in their own home first. Plastic packaging, pieces of cardboard, scraps of colored paper, bits of yarn, and small pieces of broken toys are typically dropped into a basket that the whole family rummages through whenever they need supplies for an art project. Recently, after spying a bit of shiny paper on the floor, Heather picked it up and said, "This is pretty. I'll put it in the art basket." Already, like parents, like daughter.

Heather's effort to recycle a scrap of paper rather than throw it away is a tiny gesture with a big message. It shows that even young children can learn about conserving materials and resources, and by extension, protecting the planet, in age-appropriate ways. It also shows that your child is so tuned in to your ways that it is easy to become an environmental role model. But because children are more apt to want to care for something they have a personal stake in, it's as important to expose your child to the natural world as it is to teach her ways to protect it.

This doesn't require week-long camping trips into the wilderness — although those can be fun, enlightening experiences for the whole family. Children can explore, appreciate, and learn about nature literally in their own backyard, in a park, in a community garden, and on trips to the beach or mountains. There's more good news: Giving your child opportunities to connect with nature can also help her develop crucial literacy, language, math, science, social studies, art, problem-solving, and research skills.
