She appeared on British television station ITV to further explain her decision, saying she had started noticing the pajama trend had been picked up by “30 or 40” parents at school.Despite her determination to make school a nicer place to be, Chisholm admits that she can't demand that parents dress up-such as Karen Routh, 49, who wore pajamas to drop off her 8-ycar-old daughter Holly, because she was running late and didn't feel well.“I imagine there might be some people who keep up wearing pajamas for the next six months to prove a point,” Chisholm said. “I can't force people to get dressed but I will keep sending letters home in the hope thatthey decide to put on a pair of jeans.”Wearing pajamas in public has also become a hot issue for some schools and States in theU.S.In 2015, aFloridaschool board member insisted on a dress rule for parents who showed up in the school in sleepwear.4. The headmaster asks parents to pay attention to ______.A. the way they dressB. the relations with teachersC. the way they treat their kidsD. the clothes they buy for their kids5. How does Chisholm try to change this situation?A. Asking kids to set examples.B. Keeping them out of school.C. Sending letters to persuade them.D. Forcing them to change by laws.6. Why did Kate Chisholm appear on ITV?A. She wanted to force Karen to dress properly.B. Parents spent less time on their clothes.C. She wanted to explain her decision about the parents' dress.D. She wanted to tell us more and more parents wear pajamas to school.7. It can be inferred from the last paragraph that ______.A. strict laws should be passed to stop pajamasB. aFloridaschool will force parents to wear jeansC. people wearing pajamas in public will be punishedD. more and more people are concerned about dressing properly in publicCThey are smart. They know how to steal. They know how to find food. They know how to intimidate(恐吓) . Who are they? They are macaque monkeys. They have taken over the old city ofLopburiinThailand. About 8,400 of them are in the center of the city. They roam(漫游) neighborhoods in groups. Dozens of businesses in Lopburi are closing. They include a music school, a gold shop, a barber, a cellphone store and a movie theatre. The Buddhist culture believes reducing the number of monkeys would disturb spiritual well-being.The monkeys were not always such a hazard. They attracted tourists. Buddhists thought feeding them was agood deed. Now times have changed. Recently, the coronavirus made things worse. There are fewer tourists, which means that travelers give less food to the monkeys. Over the years, the monkeys moved into empty buildings. They trashed whatever they came across. They ripped(扯掉) antennas and windshield wipers off parked cars. What happens when monkeys come into contact with humans? An observer said that years ago the monkeys were fewer, biggerand healthier. Their fur was shiny and thick. They kept to the temples，as well as the ruins of the ancient Khmer civilization.Then tourists came with easy and unhealthy food. Along with bananas and citrus(柑橘), the macaques feasted on junk food. An observer said, “The monkeys are never hungry. They are just like children who eat too much KFC. ” Compared with the monkeys of the forest, their urban counterparts have less muscle. They have more hypertension and blood disease. Their fur has thinned. Some have gone bald. With so much food available，they have more time to breed and to give birth. Their population has exploded. “These monkeys were here before us,” a man said. A juvenile macaque tugged(拽) his trousers demanding a treat. “We have to adapt to them，not the other way around. ”8. Why are macaque monkeys so popular in Lopburi inThailand?A. Because they are smart and know how to steal.B. Because they have taken over the old city ofLopburiinThailand.C. Because they are symbols of spiritual well-being in the Buddhist culture.D. Because 8,400 of them are in the centre of the city and roam everywhere.9. In what way has tourism influenced the macaque monkeys?A. The monkeys are bigger and healthier.B. The monkeys like eating KFC food.C. The monkeys have suffered from more diseases.D. The monkeys are subject to birth control.10. What does the underlined word “counterparts” in the last paragraph refer to?A. Monkeys.B. Tourists.C. Buddhists.D. Children.11. It can be inferred from what the man said that ________.A. monkeys are ancestors, so humans should adapt to monkeysB. humans should regard monkeys with awe and respectC. monkeys should be forced to follow rulesD. humans should give monkeys whatever they wantDShe is one of mankind’s oldest ancestors and is more than three million years old. New analysis of the arm bones of Lucy, an early hominid, suggests she was a tree climber. Lucy’s remains were uncovered in Ethiopia in the 1970s, with the 3.18 million-year-old skeleton(骨骼)being the most complete of any upright, walking human ancestor. Since she was discovered, researchers have debated whether she spent her life in the trees or spent time walking on the plains as well.The new evidence from scans of her arm bones proves she spent time climbing and used her arms to pull herself up. The scans were compared with cross sections of humans and chimpanzees, which spend a mixture of time in trees and walking on all fours on the ground. They found that the arm bones were more heavily built, similar to those of chimps, while her lower limbs(下肢)would have meant she walked less efficiently than modern humans. Professor John Kappelman, atUniversityofTexas, believes the advantage of his study was that it focused on characteristics that reflect actual behavior during life, suggesting that evenwhen Lucy walked upright, she may have done so less efficiently than modern humans, limiting her ability to walk long distances on the ground.Previous studies suggested that Lucy was just 4 feet tall and weighed just 65 pounds. Combining the new data paints a picture of an ancestor who may have spent a great amount of her time in trees. It also expands on evidence from earlier this year which claimed that Lucy may have died from a fall, most likely from a tree. The evidence suggests Lucy may have spent time on the ground, returning to the safety of the trees for food and to sleep, to avoid her enemies.12. What did the researchers argue about after Lucy was discovered?A. Where she lived.B. How long she lived.C. What she ate.D. How she worked.13. How could people tell Lucy spent time climbing?A. By her walking style.B. By her heavily built arm bones.C. By her strong lower limbs.D. By her large cross sections.14. When Lucy walked, she may________.A. have walked with bigger stepsB. have walked at a faster speedC. have walked more efficiently than usD. have walked a shorter distance than us15. What is the main idea of the last paragraph?A. Guesses about Lucy’s characteristics.B. Some evidence of Lucy’s health.C. The safety of Lucy.D. The ancestor of Lucy.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
