C A new report says there are now moreobesepeople in the world than there are underweight people. Researchers from Imperial College London wrote the report. The researchers examined health records from about 20 million people for what they called the “world’s biggest obesity study.” For the study, the researchers compared the body measurements of almost 20 million adults. They found that from 1975 to 2014, global obesity rates for men increased from 3.2 percent of the population to 10.8 percent. For women, it rose from 6.4 percent to 14.9 percent. The study found that more than 2.3 percent of men and 5 percent of women are considered severely obese. A severely obese individual has a body mass index (or BMI) of over 35 kilograms per square meter. BMI is a way to measure a person’s height compared to their weight. The study also found that about 1 percent of men and 2 percent of women are considered “morbidly (病态地)obese.” Such people have difficulty with simple activities because they are overweight. The researchers say there are now 55 million morbidly obese adults worldwide. Majid Ezzati is the chief writer of the report. He writes that “the number of people across the globe whose weightposesa serious threat to their health is greater than ever before. He adds that thisepidemic (流行病)of severe obesity is tooextensiveto bedealtwith just medications. He says coordinated global initiatives are needed to tackle this crisis. These initiatives include looking at the “price of healthy food compared to unhealthy food, or taxing high sugar and highly-processed foods (深加工食品).” The researchers warn if the problem of obesity worsens, 18 percent of men and 21 percent of women will be obese by 2025. （本文出处：VOA April 11, 2016）（略有改动） (1)Which kind of people are considered to suffer from morbidly obese?

School clubs are more than just after-school activities. They are a vital part of school life that can make learning more enjoyable and help students grow.Academic clubs encourage students to engage in learning beyond the classroom. For instance, a math club might hold contests and group talks that help students think in new ways and understand difficult ideas better. A science club could do fun experiments showing how school lessons work in real life. These activities make learning more interesting and help students remember what they study.Confidence plays an important role in both academic success and social interactions (互动). Clubs offer a supportive environment where students can discover new passions and get better at things they enjoy. Whether speaking in a debate club, acting in a drama club, or building robots in a tech club, students get praised for their work, which makes them feel good about themselves. Overcoming challenges in a club setting — such as presenting in front of an audience or leading a group project — helps them become stronger and more confident in all parts of life.Besides learning skills, clubs help students make friends. When students like the same things, they become friends who can share thoughts, get advice, and help each other. Liking the same things creates strong friendships that continue after school. Feeling part of a group is especially helpful during tough school times, giving students support and reasons to keep trying.Clubs naturally need teamwork, whether planning activities, sharing materials, or working toward group goals. Through these experiences, students learn to work well with others, divide up jobs, and solve problems together. Being a club leader, like president or project helper, teaches students to be reliable, make choices, and encourage their classmates. These lessons prepare students to work well with others and lead with confidence in the future.School clubs offer endless opportunities for personal development, fun, and friendship. Whether you are already a club member or are thinking about joining one, remember that every club experience is a step toward becoming the best version of yourself.Reading comprehension() 1.

Uncivilized behavior by passengers unacceptableFor the first time，airline passengers have been blacklisted for uncivilized behavior．Their names will remain on the blacklist for one or two years，according to an announcement by the China Air Transport Association on Saturday．The blacklisting means they will not be able to travel by air until their names are removed from the list．Blacklisting passengers who disobey the rules for travelling by air and so place their own interests before everything else，including safety，has long been overdue （迟到的，延迟的）．There have been frequent reports of passengers making a scene when their flight was delayed or when they believed that they were not treated as they should be on a flight．Yet it is natural for some flights to be delayed because of reasons such as bad weather or mechanical problems that need to be solved．However，some passengers seem to take it for granted that their flight must take off at the time stated on their ticket，and they even assume that the members of the cabin crew are simply there to do their bidding（吩咐）．They forget that they should behave themselves in the first place and that respect is reciprocal （互相给与的）．There is no reason for them to be respected when they do not show enough respect for others．Observing rules can never be over-emphasized when it comes to flight safety．No one has the right to disregard the rules for any reason．Of course，airlines should provide quality services to meet the needs of passengers．Yet，even if passengers are not satisfied with the service provided，there is still no reason for them to flout the rules that are designed for the safety of all．The blacklisting of these three passengers should serve for others to know they have to toe the line （顺从集体）．21．Which of the following statements is TRUE？ ____ A．Never before have airline passengers been blacklisted．B．At no time should flights be delayed，whatever the reasons．C．Members of the cabin crew should be at the passengers'service at any moment．D．If an airline passenger is blacklisted，he or she will never be allowed to travel by air．22．The underlined word"observing"in paragraph 6is closest in meaning to ____ ．A．abolishing B．violating C．setting D．obeying23．According Paragraph 4，the author's attitude towards some passengers is ____ ．A．Tolerate B．Curious C．Critical D．Neutral24．The text is most probably taken from ____ ．A．a research paper B．a newspaper report C．an advertisement D．a flight guide．
