问题解析：

Every one of us is a mother, father, son or daughter - and we all have dreams - big and small. Unfortunately, too many of us keep these dreams to ourselves because we fear what others might say. My point in writing this is to say it's OK to dream and dream big and talk about your dreams so that others are inspired to dream big too. What a world we would have if everyone did this! My dad was a dreamer. He told me that one day he was going to have a sailboat. We would go to the boat shows whenever they came to town and climb into them. My father would talk to the sales people and I would be busy pretending to sail the boat. It was fun. Then one day we went to the boat place and took out a sailboat on the ocean, what a thrill! Soon afterwards he

bought his first boat and named it "LETSGO" and we sailed and sailed big bays and seas around New England. When I was older I got to be the skipper because he not only told me his dream he showed it to me and let me taste the idea on my own. Now I was inspired to dream big too. You see dreams can do wonders for you. When you believe in your dreams, they take on a life of their own. Now you start dreaming up things to do to make your inspiration a reality. More dreams, more inspiration, then more dreams and a few more. Then one morning you wake up and the dream has come true. My dreams have taken me to so many beautiful places; I've been below the surface of the ocean watching the beauty of coral and fish as I swim by. I've flown an airplane with pontoon floats from a lake in northern Maine and another different plane on a flight over the Grand Canyon. I've also ridden under my own wind blown sails. The pictures in my head are priceless and better than any I've taken. Some of the best times I've had were listening to older people talk about their dreams and what their dreams did for their lives. When I hear some of their dreams it inspires me to think and dream how I might do that too. I interviewed a man some years ago who was 80-something years young. He was a sturdy man with the hands to match the story he told me. Hands still strong enough to crack the shells of the walnuts he offered me and munched on. He had outlived his wife but still lived in their neat home with bookcases near the fireplace he no doubt built. I asked one question and I didn’t move for hours. His story of leaving home to explore the world and learn a new trade was fascinating to my young mind. But it was after hearing his tale that I realized what he was really saying to me - not as an aspiring journalist but as a person. He told me he dreamed that he would have a great life and he had one, so, I could dream about having a great life and get one too. Just as my father had said to me earlier, here was another confirmation. I did just what they said to do, because I could do anything I wanted. Therefore, I say dream... dream big dreams about your great life to come. I？heading out toward my next one, how about you?

问题解析：

We always believe that life will be better after we get married, have a baby, than another. Then we are frustrated that the kids aren't old enough and we'll be more content when they are. After that we're frustrated that we have teenagers to deal with. We always tell ourselves that our life will be complete when our spouse gets his or her act together. when we get a nice car, and are able to go on a nice vocation when we retire. The truth is, there's no better time than right now. If not now, when? Yur life will always be filled with challenges. It's best to admit this to ourselves and decide to be happy anyway. One of my favorite quotes comes from Alfred Souza. He said. "for a long time it had seemed to me that life was about to begin-real life. But there was always some obstacle in the way, something to be gotten through first, some unfinished business, time still to be served, a debt to be paid. Then life would begin. At last it dawned on me that these obstacles were my life." This perspective has helped me to see that there is no way to happiness. Happiness is the way. So treasure every moment that you have and treasure it more because you share it with someone special, special enough to spend your time with…ans remember that time waits for no man. So stop waiting until you finish school, until you go back to school; until you lose ten pounds ,until you have husband and kids; until your kids leave the house; until you get a new car, until you retire. Happiness is a journey, not a destination. So, work like you don't need money, love like you've never been hurt before; Dance like no one's watching.

问题解析：

Do other animals besides humans cry? The answer to the question is ‘Yes, and no’. All animals with mobile eyes have the ability to cry, just as we humans do. They have a tearing system that keeps their eyes wet so as to protect them from dry sand, dusts, and other elements. People often tell tales of animals such as elephants and dogs weeping when punished. However, even if such an animal does shed tears, there is no scientific evidence that the animal is expressing the tear-related emotions similar to those when humans cry. But what about when a baby chimp or ape whimpers and screams when it’s being separated from its mother, can we say with some

certainty that the animal is crying? Taking away the babies does encourage care-giving such as feeding and protecting from the mother apes, but it is uncertain whether the baby apes feel the same way as baby humans do when they cry. In fact, it’s not clear that crying and other emotional displays mean exactly the same thing to all humans. For instance, there is a wide range of emotions that prompt people to cry, and some kinds of weeping, such as crying at a stranger’s wedding, seem to be cultural responses. In addition, some people are autistic. That means they prefer being alone than being with other people, especially in large crowds. These people are said to have less ability in expressing their emotions, but research also has shown that it’s more that their expressions and their reactions to the emotional expressions of others are unusual. Different. But does that mean that their sadness is different somehow? So even if apes can be said with some certainty to be feeling emotions, then there is the problem of figuring out to what extent what they feel resembles what humans feel.

10.(单选题) What does the author mean by “Yes, and no”in line 1, paragraph 1?

A. Other animals besides humans cry

B. No other animals besides humans cry

C. Animals cry but do not cry like humans

Unlike many ants, trees grow slowly. Thirty to eighty years are necessary before a tree grows to the right size for harvesting as lumber or pulpwood. But a tree crop can be a good investment for a landowner or farmer, since trees will grow on the parts of his land where ordinary crops will not grow. Trees 1 much more than provide lumber for home building. They provide raw materials for making paper, plastics, synthetics, turpentine, and other products. Even more important, trees protect the nation?s water supply by holding 2 erosion and keeping water in the soil. America once had huge natural forests. To start their 3 , pioneers cleared many trees. Later, logging crews 4 by lumber companies moved into other forests. They cut all the valuable trees, and then moved on.. There were few 5 to protect our forests or to plant new ones until the beginning of the present century. Then, 6 with forest experts, government officials, and landowners, the lumber companies began planning to support the planting of new forests. The American Tree Far System, begun during World War II, is one of the plans that grew 7 this cooperation. Landowners who wish to establish tree farms can get help from a professional. state-employed forester, or from an association of lumber companies. They can get 8 on what kind of trees to plant and how to care for them. Landowners must protect their trees by keeping grazing animals 9 and by removing dead or diseased trees. They must keep replanting, so that young trees are growing at all times to replace those 10 for cutting. Some tree farms are small woodlots. Others cover thousands of acres. All together, they are of great value to the United States and its people. 1. A. create B. devote C. have D. do
