Sir John a British scientist who won last year's Nobel prize for medicine, said he had predicted at the time of his frog experiments that the successful cloning of a mammal would happen within 50 years.and that "maybe the same answer is appropriate" far the step to human cloning. Parents who lose children in accidents may be able to clone "copies" to replace them then. Although any attempt to clone an entire human would raise complex moral issues, the biologist claimed people would soon overcome their concerns if the technique became medically useful.Cloning was regarded with extreme doubts when it was first developed but became widely accepted after the birth of Louise Brown, the first "test tube baby" He said, "When my first frog experiment.s were done, an American reporter asked how long it will be before these things can he done in mammals or humans I said, 'Well, it could be anywhere between 10 years and 100 years-how about 50 year ?' It turned out that it wasn't far off the mark as far as Dolly was concerned.Maybe the same answer is appropriate." Sir John added that cloning a human being effectively means making an identical twin, and doctors would therefore simply be "copying what nature has already produced" The average vote on allowing parents of deceased children, who are no longer fertile , to create another using the mother's eggs and skin cells from the first child, thinking the technique was safe and effective, is 60 per cent in favor.The reasons for "no" are usually that the new child would feel they were some sort of a replacement for something. . According to the text, which statement is NOT true? A) Louise Brown is the first "test tube baby". B) Human cloning is still a controversial topic. C) Sir John is positive about the future of human cloning. D) Human cloning is creating something that didn't exist before.

It had been a difficult move. I'd left my family and friends in Indiana, the beloved state where I'd lived most of my life. My new home in Florida was thousands of miles away from anything I knew. It was hot--all the time. Jobs were hard to come by, but I was up for almost any challenge. At last, I taught in a special school where students have severe learning and behavioral difficulties. Another teacher and I had spent weeks teaching the children appropriate behavior for public outings. Unexpectedly, only a few students, including Kyle, had not earned the privilege of going. He was determined to make his disappointment known. In the corridor between classrooms, he began screaming, cursing, spitting, and swinging at anything within striking distance. Once his outburst died down, he did what he'd done when he was angry at all his other schools, at home, even once at a juvenile detention center. He ran. People watched in disbelief as Kyle dashed straight into the heavy morning traffic in front of the school. I heard someone shout, "Call the police!" But I ran after him. Kyle was at least a foot taller than me. And he was fast. His older brothers were track stars at the nearby high school. But I could run long distances without tiring. I would at least be able to keep him in my sight and know he was alive. After several blocks of running directly into oncoming traffic, Kyle slowed his pace. He took a sharp left. Standing next to a trash bin, Kyle bent over with his hands on his knees. I must have looked ridiculous. But his was not a look of fear. I saw his body relax. He did not attempt to run again. Kyle stood still and watched me approach. I had no idea what I was going to say or do, but I kept walking closer. He opened his mouth to speak when a police car pulled up, abruptly filling the space between Kyle and me. The school principal and an officer got out. They spoke calmly to Kyle, who willingly climbed into the back of the vehicle. I couldn't hear what was said, but I didn't take my eyes off Kyle's face,... What is the best title of the passage? A) Kyle, a Boy with Learning and Behavior Difficulties. B) The Teacher Who Ran. C) A School with Special Students. D) A Terrible Conflict.

Q: There is one type of illness in the world that affects more people than anything else and is very deadly. If untreated this illness could affect everything you do. What is this illness? Depression. Serious depression requires professional treatment. Self-induced depression is something each of us can change. Everyone's circumstances are different, but the causes of self-induced depression are common: low self-esteem, hurtful thinking and a bad attitude. So how can we change the way we think, feel, and cultivate a cheerful attitude? First we must look at ourselves, truly and honestly examining our motives for what we wish to achieve. If you are dissatisfied because you feel you haven't or can't do anything, then one step is needed - to set goals. Always start your goals relatively small and easy to attain. Think of them as sand; one grain may be insignificant but as a group they form the beach. Once you have set and attained small goals for yourself, move on to slightly larger, more challenging goals. It takes more than just setting goals to be happy. It takes positive thinking. How can we attain this? There are a number of factors that can make us think negatively and one of those is diet. In my opinion, a person who eats a lot of take out and fast food is feeding their body junk. Start by eating better foods which give the body much NEEDED minerals. If your physical body is happy, it's much easier for your mental body or "thinking ability" to be happy. Next, exercise. A half-hour a day is recommended for positive well being. Then think about good memories you had, or generally think of things that make you smile. Remember, everything you wear costs money but to wear a smile is free. A smile can be the difference between an average day and a great day. If you follow these steps, positive change is inevitable. What's the passage mainly about? A) To prove the argument that depression can be changed. B) To analyze the danger depression can bring to people. C) To introduce to readers how to keep positive thinking. D) To recommend some ways to deal with depression.
A: D
(Q).
A proverb says "Time is money." But in my opinion , time is even more precious than money. Why? Because when money is spent, we can earn it back. However, when time is gone, it will never return. This is the reason why we must value time. The time we can use is limited . Therefore, even an hour is extremely precious. We should _ our time to do useful things. As students we must put more efforts into our lessons so as to serve society and our nation in the future. But it is a pity that there are a lot of people who do not know the importance of time. They spend their precious time smoking, drinking and chatting. They do not realize that wasting time is equal , we should form the good habit of saving time. Do not put off what can be done today until tomorrow. Which of the following is a good habit of saving time? A) Spending time chatting and playing cards. B) Often asking some friends to drink together. C) Playing computer games all day. D) Never leaving today's work for tomorrow.
