AIn the movie Jurassic Park, scientists clone dinosaurs by using the DNA that was preserved for millions of years. However, there is trouble when the cloned dinosaurs turn out fiercer and smarter than expected. Can dinosaurs really be cloned? Theoretically, they can; all that would be required is DNA from an extinct dinosaur and a currently living closely related species which would act as a surrogate mother (代孕母亲). In fact, there is continuing research to clone the Woolly Mannoth by extracting (提取) the DNA from frozen animals.Actually, cloning is a phenomenon that occurs naturally in a wide variety of species. Whenever you see a pair of identical twins, they are examples of nature’s clones. Although scientists have been cloning certain plants like the carrot quite successfully for decades, attempts at cloning animals have not been as successful. However, they began long before the birth of Dolly, the sheep—the first mammal to be successfully cloned.Cloning humans does give rise to some misgivings, raising a number of moral problems involved. In fact, the social influences of producing humans artificially were brilliantly explored in the famous novel Brave New World by Aldous Huxley, and also in the movie The Island.Human cloning is basically about creating a genetically (基因地)identical copy of a previously existing person. Why would some people choose to clone human beings? Well, generally, it could make couples unable to have babies have their own children. Replacing a dead child is also another reason why some people have expressed interest in the technology.1.We can infer from the second paragraph that ________.A.

Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to withdraw from college to care for her. It meant that school and my personal dream would have to wait.Then I got married with another dream: building my family with a combination of adopted and biological children. In 1999, we adopted our first son. To lay eyes on him was fantastic — and very emotional. A year later came our second adopted boy. Then followed son No. 3. In 2003, I gave birth to another boy.You can imagine how fully occupied I became, raising four boys under the age of 8! Our home was a complete zoo—a joyous zoo. Not surprising, I never did make it back to college full-time. But I never gave up on the dream either. I had only one choice: to find a way. That meant taking as few as one class each semester.The hardest part was feeling guilty about the time I spent away from the boys. They often wanted me to stay home with them. There certainly were times I wanted to quit, but I knew I should set an example for them to follow through the rest of their lives.In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree!I am not special, just single-minded. It always struck me that when you’re looking at a big challenge from the outside it looks huge, but when you’re in the midst of it, it just seems normal. Everything you want won’t arrive in your life on one day. It’s a process. Remember: little steps add up to big dreams.5.Why did the author quit school in her second year of college?A.

Jason Morris, executive vice president of NatureBridge says when they are not sleeping, eating or in a laboratory, the students spend their time outdoors.Julia Washburn is associate director of education and interpretation for the National Park Service.
