I’m walking on a path in the forest in the Central African Republic. Unexpectedly, I’m face-to-face with the gorilla, who begins screaming at 2 top of her lungs. That makes her baby scream, and then a 400-pound male appears. He screams the 3 (loud) of all. The noise shakes the trees as the male beats his chest and charges toward me. I quickly lower myself, ducking my head to avoid 4 (look) directly into his eyes so he doesn’t feel 5 (challenge). My name is Mireya Mayor. I’m a 6 (science) who studies animals such as apes and monkeys. I was searching 7 these three western lowland gorillas I’d been observing. No one had seen them for hours, and my colleagues and I were worried. When the gorillas and I frightened each other, I was just glad to find 8 (they) alive. True to a gorilla’s unaggressive nature, the huge animal 9 (mean) me no real harm. He was just saying: “I’m king of this forest, and here is your reminder!” Once his message was delivered, he allowed me 10 (stay) and watch. 1.____________ 2.____________ 3.____________ 4.____________ 5.____________ 6.____________ 7.____________ 8.____________ 9.____________ 10.____________ 二．（共10小题；每小题1.5分，满分15分）(2018年6月浙江卷) Few people I know seem to have much desire or time to cook. Making Chinese 1 (dish) is seen as especially troublesome. Many westerners 2 come to China cook much less than in their own countries once they realize how cheap 3 can be to eat out. I still remember 4 (visit) a friend who’d lived here for five years and I 5 (shock) when I learnt she hadn’t cooked once in all that time. While regularly eating out seems to 6 (become) common for many young people in recent years, it’s not without a cost. The obvious one is money; eating out once or twice a week may be 7 (afford) but doing this most days adds up. There could be an even 8 (high) cost on your health. Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in 9 (weigh) problems. If you are not going to suffer this problem, then I suggest that the next time you go to your mum’s home 10 dinner, get a few cooking tips from her. Cooking food can be fun. You might also begin to notice the effects not only on your health but in your pocket. 1.____________ 2.____________ 3.____________ 4.____________ 5.____________ 6.____________ 7.____________ 8.____________ 9.____________ 10.____________
强化技能限时训练(十四) 阅读理解(主旨大意类)+阅读填句 (限时35分钟) Ⅰ.阅读理解 ( A ) 【社会文化类】 I am a strong believer that if a child is raised with approval,he learns to love himself and will be successful in his own way. Several weeks ago,I was doing homework with my son in the third grade and he kept standing up from his chair to go over the math lines. I kept asking him to sit down,telling him that he would concentrate better.He sat but seconds later,as if he didn’t even notice he was doing it,he got up again. I was getting frustrated,but then it hit me. I started noticing his answers were much quicker and accurate when he stood up. Could he be more absorbed while standing up? This made me start questioning myself and what I had been raised to believe. I was raised to believe that a quiet,calm child was a sure way to success. This child would have the will power to study hard,get good grades and become someone important in life. Now those same people perhaps come to realize that their kids are born with their own sets of DNA and personality qualities,and all you can do is loving and accepting them. As parents,throughout their growing years and beyond that,we need to be our kids’ best cheerleaders,guiding them and helping them find their way. I have stopped asking my son to sit down and concentrate. Obviously,he is concentrating just in his own way and not mine. We need to learn to accept our kids’ ways of doing things. Some way may have worked for me but doesn’t mean we need to carry it through generations. There is nothing sweeter than being personal and unique.It makes us free and happy and that’s just the way I want my kids to live their own lives. 1.Time and again the author got his son seated in order to make him . A. work fast B. go polite C. stay relaxed D. keep attentive 2.The underlined “it” (in the first paragraph) probably refers to . A. his son’s doing better while standing up B. his failure in keeping his son under control C. his own experience as a school boy D. his disappointment with his active child 3.By this passage,the author attempts to tell other parents to . A. correct their kids’ manners from the early ages B. respect and trust their kids’ ways of behaviors C. develop a good relationship with their children D. guarantee their children’s freedom at home 4.Which of the following would be the best title of the passage?( ) A. Parental help with teens’ study B. Adult influence on teen growth C. Kids’ success in their own styles D. Friendship between generations
高二英语限时训练十一 一、完形填空 The True Story of Treasure Island It was always thought that Treasure Island was the product of Robert Louis Stevenson's imagination. 36 , recent research has found the true story of this exciting work.

Robert suddenly 47 something of an adventure story in the boy's 48 . While the rain was pouring, Robert sat down by the fire to write a story.

Robert had always wanted to 51 such a man in a story. 52 Long John Silver, the pirate with a wooden leg, was 53 . So, thanks to a 54 September in Scotland, a friend with a wooden leg, and the imagination of a twelve-year-old boy, we have one of the greatest 55 stories in the English language. 36. A. However B.

A Famous centenarians (百岁老人) still active in arts, science are in no mood to retire. "Those who stand still, die," is one of Oliveira's favorite phrases. He knows from experience what it means, as the Portuguese film director has reached the age of 102 and is still active in his profession. Every year, Oliveira shoots a film and is currently working on his next project. "You have to work, work, work in order to forget that death is not far away," he said. When asked about his age, Oliveira said with some humility: "It's down to mother nature. It gave to me what it took from others." Being both mentally and physically fit in old age is partly a matter of luck, but it also has something to do with character. Not every white-haired person is wise and social skills, openness and the ability to train the brain are essential for senior citizens. Along with the architect Oscar Niemeyer (103), Nobel laureate Montalcini (101) and director Kurt Maetzig (100), Oliveira is one of those people of whom it would be very wrong to think as members of a listless elderly generation. Another master in his profession is the architect Oscar Niemeyer. The 103-year-old Brazilian is best known for his futuristic-looking（未来派的）buildings in Brasilia, but he also speaks out on behalf of the poor. "The role of the architect is to struggle for a better world where we can develop a form of architecture that serves everyone and not just a privileged few," said Niemeyer recently. He spends almost every day working in his office in Copacabana, and even when he falls ill he keeps working on ideas: After a gallbladder (胆囊) operation he composed a samba tune (桑巴舞曲) in the clinic. Another man who could sing a song about age is 107-year-old Heesters. The Dutch-born opera singer spent most of his life performing in Germany, where he still works. Recently Heesters said: "I want to be at least 108-years-old." He also plans to keep performing. "Should I just sit at home and wait until they come and pick me up?" Heesters has not given up trying to add to his tally of awards and is looking for a "good stage role". Italian scientist Rita Levi-Montalcini, who is 101-year-old and is still active in medical science, has described the force that keeps driving her on: "Progress is created through imperfection." In 1986 she and her lab colleague were awarded the Nobel Prize for Medicine for their work on nerve growth factor. She's convinced that humans grow on challenges.

I was nine years old when she entered our home in rural Virginia. My father 1 me to her with these words: “I would like you to meet the fellow who is 2 for being the worst boy in this area and will probably start throwing stones at you no 3 than tomorrow morning.” My stepmother walked over to me, 4 my head slightly upward, and looked me right in the eye. Then she looked at my father and replied, “You are 5 . This is not the worst boy at all, 6 the smartest one who hasn’t yet found an outlet（释放的途径）for his enthusiasm.” Her words began a(n) 7 between us. No one had ever called me smart. My family and neighbors had built me up in my 8 as a bad boy. My stepmother changed all that. She changed many things. She 9 my father to go to a dental school, from which he graduated with honors. She moved our family into a town, where my father’s career could be more 10 and my brother and I could be better 11 . When I turned fourteen, she bought me a secondhand 12 and told me that she believed that I could become a writer. I knew her enthusiasm, I 13 it, and I saw how it had already improved our lives.
