I wrote down all the numbers carefully and found some interesting things.​ For homework: 60% of my classmates spent 2 to 3 hours on it each weekend. 25% only took 1 hour, and just 15% spent over 3 hours. It seems most of us have a proper amount of homework.​ When it comes to sports: 40% exercised for just 30 minutes, 35% played sports for 1 hour, and 25% didn’t do any sports at all. I think we need more sports because they keep us healthy.​ For screen time (like watching videos or playing games): 70% used screens for 2 hours or more! Only 20% spent 1 hour, and 10% less than 1 hour. This time is a bit too long, I think.​ We should balance our weekend time—do more sports and cut down screen time. 1 / 13 学科网（北京）股份有限公司 $沪教牛津英语 2024新版8年级上册 8上U2 Amazing numbers 综合练习 一.单词基础巩固练习, 注意适当形式 1.We looked __________ (到处) for the lost cat in the neighborhood, but it was nowhere to be found. 2.The temperature in this city dropped __________ (急剧地) after the heavy rain last night. 3.You should keep your __________ (承诺) to help your friend with his math homework. 4.Can you tell me the __________ (确切的) time when the train will arrive at the station? 5.The winner of the painting competition received a valuable __________ (奖品) from the mayor. 6.Our __________ (航班) to Shanghai was delayed for two hours because of bad weather. 7.Please put the chess pieces back on the __________ (棋盘) after we finish the game. 8.She wears a beautiful __________ (银) bracelet that her mother gave her on her birthday. 9.I sent a message to my pen pal last week, but I still haven’t got her __________ (回复). 10.Climbing the Great Wall in winter is a big __________ (挑战) because it’s very cold. 11.The little boy can __________ (数数) from 1 to 50 in both Chinese and English. 12.My parents finally __________ (同意) to let me go to the summer camp with my classmates. 13.We need to make a __________ (预算) for our trip to Guilin to avoid overspending. 14.He is __________ (目前) studying at a university in Beijing, majoring in computer science. 15.The teacher asked us to __________ (检查) our test papers again before handing them in. 16.About 70 __________ (百分比) of the students in our class like playing basketball after school. 17.Yunnan is a __________ (省) in the south of China, famous for its beautiful scenery. 18.She spoke without __________ (犹豫) when the teacher asked her to share her ideas. 19.This new phone __________ (系统) is easier to use than the old version. 20.I __________ (想知道) if we can visit the science museum this weekend. 21.She will __________ (代表) our school in the national English speech competition next month. 22.I write all my important events in a __________ (日程表) to make sure I don’t forget them. 23.The red flag is a __________ (象征) of courage and loyalty in many countries. 二.在空白处填入所给单词的适当形式。 1.The ___________ (fly) to Tokyo was canceled because of the heavy snow. 2.The ___________ (schedule) training course for new employees will start next Monday. 3.This math competition is much more _________________ (challenge) than the one we took last year. 4.My father has a ____________ (prize) collection of old coins that he’s kept for 20 years. 5.Tom is a ____________ (promise) young athlete who has won many regional competitions. 6.After playing chess, we should put all the pieces back on the ____________ (chess). 7.The lake shone with a soft, ___________ (silver) light under the moonlight. 8.She ___________ (reply) to my WeChat message as soon as she finished her homework last night. 9.He was ____________ (hesitation) to ask the teacher for help because he was shy. 10.What a _____________ (wonder) performance the students gave at the school concert! 11.After hours of discussion, the two teams finally reached an ____________ (agree) on the cooperation plan. 12.You can check the _____________ (currently) news on this app to know what’s happening around the world. 13.My aunt bought a stylish ________ (check) shirt when she went shopping last weekend. 14.They have ___________ (budget) for their summer vacation carefully to avoid overspending. 15.This hospital is one of the most famous _____________ (province) medical centers in Guangdong. 16.There’s a ___________ (sharply) turn ahead, so please slow down your car. 17.These nouns are _____________ (count) nouns, so we can use “a/an” before them. 18.We need to develop a more ____________ (system) way to manage our daily tasks. 19.The dove ________ (symbol) peace and friendship in most cultures around the world. 20.She was elected as the _______________ (represent) of our class to attend the school meeting. 21.Can you tell me the ___________ (exactly) time when the movie will start? 三.课文语法填空 The old man and the king A long time ago, there was a king ______ India.
