But sometimes, our way of thinking can become an obstacle (障碍).Julia Watzek, a graduate student in psychology at Georgia State University, US, recently did some research on the problem-solvingabilities of both monkeys and humans. She and her team tested their ability tochange their strategies (策略) by having them play a simple game.In this game, each player was shown four squares on a computer screen: onestriped square (有条纹的正方形), one spotted (有斑点的) square and two blanksquares. While being trained to play the game, they learned that clicking (点击) thestriped square and then the spotted square would cause a blue triangle (三角形) topop up in one of the blank squares. Clicking on the blue triangle would give them areward –human players would hear a “woop!” sound and monkey players wouldreceive a snack.But partway through the game, the researchers introduced a shortcut (捷径). Suddenly, the blue trianglestarted appearing at the start of gameplay, alongside the striped and spotted squares. If a player c licked on theblue triangle, they’d receive their reward right away.Remarkably, about 70 percent of the monkeys figured out this shortcut immediately. Humans, on the othe r hand, were slow to figure it out. Only 1 out of 56 human players figured out the shortcut right away.Watzek’s conclusion was that humans tend to (倾向于) get “stuck in their ways” when it comes to strategi c thinking. Things such as standardized testing and formal schooling might cause humans to use the same strateg yover and over, even when it doesn’t work very well.1.

According to Watzek, the research shows us that _____.A. monkeys’ way of thinking works best for playing gamesB. humans tend to use the same strategy repeatedlyC. 70 percent of the monkeys are smarter than humansD. humans are not good at solving simple problems时事热点（二）Students learn how to do CPR. 中国公众的急救意识有待提高。

On Nov 27, some sad news shocked many people in China. Godfrey Gao (高以翔), a Chinese-Canadian actor, died from cardiac arrest (心脏骤停) while shooting a sports reality show at 1:30 am in Ningbo. He was only 35.The show’s producer, Zhejiang Satellite TV, said medical staff began performing firstaid (急救) right away before he was taken to the hospital. But netizens doubt whether firstaid could’ve helped to save Gao’s life.In fact, 550,000 people in China suffer from sudden cardiac arrest every year,according to the National Center for Cardiovascular Diseases. Only about 1 percent aresaved.If people nearby can perform CPR (心肺复苏) and use AEDs (自动体外除颤器) within four minutes of a heart attack, the patient’s (患者的) chances of surviving (挺过) sudden cardiac arrest can be greatly improved, Chen Zhi, director of the Beijing Emergency Medical Center’s training center, said to China Daily.However, many people in China do not know how to perform CPR and there are not enough AEDs in public places, he said.According to the National Health Commission, less than 1 percent of Chinese adults know how to perform CPR. And the country only had about 15,000 AEDs installed (安装) in medical institutions and public places such as airports and subways as of last year.For every 100,000 people, Japan has 394 AEDs and the United States has 317. In China, the figure is only 0.2, according to a report from CCTV.Apart from installing more AEDs, there is still more that can be done to improve people’s first aid awareness (意识), according to Lin Jian from Peking University People’s Hospital. Schools should give students first aid classes. Companies should also offer regular training. People should avoid working for long time and make sure to warm up before doing intense (剧烈的) exercise.1.

How many people are saved from sudden cardiac arrest in China every year?A. 550,000B. 55,000C. 5,500D. 5503. According to Chen Zhi, what can be done to improve this situation?a.
