请认真阅读下面短文,并根据短文内容回答问题。
   We parents like to make sure that our children are eating well and getting all the nutrients(营养)they need. Children need two or three kinds of vegetables every day.
   A simple way to get children to eat vegetables is eating them ourselves. Following our habit, they may start eating vegetables. Don’t say things like, “If you eat your vegetables, you can have desserts(餐后甜食).” These methods work for a while but can possibly lead them to disliking vegetables more. Giving your children new varieties(多样性) which will help her or him develop a taste for trying new things.
Sometimes the simple things just don’t work. We have to start becoming a little creative when it comes to make our children eat these vegetables. By doing this in the beginning when they are small, it will hopefully help them learn to love vegetables.
   Think of creative ways to make children eat vegetables. For example, cut up vegetables like carrots, tomatoes, and assemble (集合) a creative way on a plate for an afternoon snack. Or try using cheese sauce either by dipping(浸)vegetables or by putting the cheese right on top of the uncooked vegetables.
   If you prefer, you can also add a teaspoon of sugar on top of cooked green beans and peas to give them a little sweeter taste. Doing this shouldn’t lead to a sweet tooth as long as you only give them a small amount.
   If you have a child that refuses to eat vegetables, some of these suggestions I’ve listed will help to turn that around. In the end, you’re not just getting them to eat vegetables, you are helping them to live a healthier lifestyle.
