Ⅳ.语法填空

To a large degree, the measure of our peace of mind is __1__ (determine) by how much we are able to live on the present moment. Regardless of what happened yesterday___2__ last year, and what may happen tomorrow, the present moment is where you are — always!

Without question, many of us spend too much of our lives __3__ (worry) about variety of things around us. We allow past problems and future concerns to dominate (支配) our present moments, so much so that we end __4__ anxious, frustrated, depressed, and hopeless. On the other hand, we also postpone our sense of satisfaction, our stated priorities (优先处理的事), and our __5__ ( happy ), often

convincing ourselves that “someday” will be much better __6__ today. Unfortunately, the same brain __7__ tells us to look toward the future will only repeat itself so that “someday” never __8__ (actual) arrives. John Lennone once said, “Life is what is happening while we are busy making other plans.” When we are busy making “other plans”， our children are busy growing up, __9__ people we love are moving away and dying, our bodies are getting out of shape, and our dreams __10__ (slip) away. In short, we miss out on life.
