短文填空
阅读短文，在空格处填入一个适当的单词或括号中单词的正确形式。
We spend a lot of time caring for the people we love. We pack lunchboxes, plan meals, and worry about $^{(1)}$ everyone is happy or not. Too often, we forget $^{(2)}$ (care) for ourselves.
This often begins with small daily things. A parent misses breakfast, drinks coffee until noon, and calls it “lunch”. At first, it seems $^{(3)}$ ______ (harm). But by mid-afternoon, tiredness hits. Patience disappears. The rest of the day feels $^{(4)}$ ______ a struggle.
However, these small habits can be changed. In fact, even small changes can make a big $^{(5)}$ (different). You don’t need to spend hours preparing healthy food. A simple morning smoothie (奶昔)—just frozen fruit, yogurt, and a little protein powder (蛋白粉)—takes only two minutes. If you want to make things even $^{(6)}$ (easy), try preparing food ahead of time. Just fifteen minutes on Sunday night can make the whole week $^{(7)}$ (feel) better. So why don’t we do it? The truth is, we often spend half an hour preparing food for our children but refuse to spend five minutes $^{(8)}$ ourselves. We forget that our own health $^{(9)}$ (matter) too.
Caring for yourself is not a sign of weakness. It is part of living a good life. When you are healthy and strong, you can give more love to the people around you. And that is $^{(10)}$ (true) beautiful.
