题目内容

Dinosaurs ruled the planet for millions of years, and they are generally believed to have gone extinct.But the reality is that modern versions of dinosaurs are all around us. Scientists have been exploring similarities between birds and dinosaurs; and new research shows that these two types of animals are directly linked.

The connections between birds and dinosaurs are explored in a new museum exhibit called Dinosaurs Among Us at the American Museum of Natural History in New York City.

According to Mark Norell, the director of the exhibit and an expert at the museum, it is based on new scientific evidence collected over the last two decades. "I think this is really going to shake up the way people think of dinosaurs “ Norell told reporters.” One could argue that we still live in the age of dinosaurs."

The exhibit includes ancient fossils and lifelike models of dinosaurs of all sizes to show the evolution of dinosaurs into birds. It examines several properties that are shared between the two species, including feathers, complex brains, the shapes. And sizes of eggs, and the ability to fly. Birds today make nests, lay eggs and tend to babies. Fossil research shows that some dinosaurs also made nests and laid eggs. Also，birds have hollow（中空的）bones, which don’t weigh much and allow birds to take more air into their lungs. These adaptations help with flight. Some dinosaurs had these properties as well. In addition, the exhibit shows that there are many similarities between the legs, claws; and feet of dinosaurs and birds.

Norell noted that the research behind this exhibit is the result of advanced scientific, techniques; and new technologies. For example researchers used a scanning (扫描) process called computed tomography (CT) to look inside the brains of extinct dinosaurs. It combines with many X-rays to produce a 3D image. "Modern technology tells us more than we thought

we could ever know about the connections between dinosaurs and birds," Norell said.

The summer holiday is coming. My classmates and I are talking about how to do during the holiday. We can chose between staying at home and take a trip. If we stay at home, it is comfortable but there is no need to spend money. But in that case, we will learn little about world. If we go on a trip abroad, we can broaden your view and gain knowledges we cannot get from books. Some classmates suggest we can go to places of interest nearby. I thought that it is a good idea. It does not cost many, yet we can still learn a lot.

The easy way out isn’t always easiest. I learned that lesson when I decided to treat Doug, my husband of one month, to a special meal. I looked through my cookbook and chose a menu which included homemade bread. Knowing the bread would take time, I started on it as soon as Doug left for work. As I was not experienced in cooking, I thought if a dozen was good, two dozen would be better, so I doubled everything. As Dong loved oranges, I also opened a can of orange and poured it all into the bowl. Soon there was a sticky dough（面团）covered with ugly yellowish marks. Realizing I had failed, I put the dough in the rubbish bin outside so I wouldn't have to face Doug laughing at my work.

I went on preparing the rest of the meal, and, when Doug got home, we sat down to Cornish chicken with rice. He tried to enjoy the meal but seemed disturbed. Twice he got up and went outside, saying he thought he heard a noise. The third time he left, I went to the windows to see what he was doing. Looking out, I saw Doug standing about three feet from the rubbish bin, holding the lid up with a stick and looking into the container. When I came out of the house, he dropped the stick and explained that there was something alive in out rubbish bin. Picking up the stick again, he held the lid up enough for me to see. I felt cold. But I stepped closer and looked harder. Without doubt it was my work. The hot sun had caused the dough to double in size and the fermenting yeast （酵母）made the surface shake and sigh as though it were breathing. I had to admit what the 'living thing 'was and why it was there. I don't know who was more embarrassed by the whole thing--Doug or me?

I had started a small company several years ago. I worked hard to make it successful. It was a sign-making business. It was a small company, and it was private.

Still, I worked hard building up my business. I did not work only a few hours each day—no banker's hours for me. Instead I spent many hours each day, seven days a week, trying to grow the company. I never cut corners or tried to save on expenses. I made many cold calls. I called on possible buyers from a list of people I had never seen. Such calls were often hard sells.

Sometimes I sold my signs at a loss. I did not make money on my product. When this happened, there were cut backs. I had to use fewer supplies and reduce the number of workers. But after several years, the company broke even. Profits were equal to expenses. And soon after, I began to gain ground. My signs were selling very quickly. They were selling like hotcakes.

I was happy. The company was moving forward and making real progress. It was in the black, not in the red. The company was making money, not losing it.

My friend knew about my business. He is a leader in the sign-making industry—a real big gun, if you know what I mean. He offered to buy my company.

He offered me a ball park estimate of the amount he would pay to buy my company. But I knew his uneducated guess was low. My company was worth much more. That is, he asked his accountant to take a close look at the finances of my company and decide how much it was worth. Then my friend increased his offer.

My friend's official offer was finally given to me in black and white. It was written on paper and more than I ever dreamed. I was finally able to get a break. I made a huge profit on my company, and my friend also got a bang for the buck. He got a successful business for the money he spent.

A. A big gun. B. A proud fellow.
