体裁 话题 麻疹在历史上带来的危害及麻疹患者数说明文 量增多的原因 362 ★★★★☆ 6分钟 词数 难度 建议时间 （2017·北京卷阅读理解)Measles(麻疹), which once killed 450 children each year and disabled even more,
was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine(疫苗). But the disease is making a comeback, caused by a growing anti-vaccine movement and misinformation that is spreading quickly. Already this year, 115 measles cases have been reported in the USA, compared with 189 for all of last year.
The numbers might sound small, but they are the leading edge of a dangerous trend. When vaccination rates
are very high, as they still are in the nation as a whole, everyone is protected. This is called “herd immunity”, which protects the people who get hurt easily, including those who can’t be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn’t work.
But herd immunity works only when nearly the whole herd joins in. When some refuse vaccination and seek a
free ride, immunity breaks down and everyone is in even bigger danger.
That’s exactly what is happening in small neighborhoods around the country from Orange County, California,
where 22 measles cases were reported this month, to Brooklyn, N.Y., where a 17-year-old caused an outbreak last year.
The resistance to vaccine has continued for decades, and it is driven by a real but very small risk. Those who
refuse to take that risk selfishly make others suffer.
Making things worse are state laws that make it too easy to opt out(决定不参加) of what are supposed to be
required vaccines for all children entering kindergarten. Seventeen states allow parents to get an exemption（豁免), sometimes just by signing a paper saying they personally object to a vaccine.
Now, several states are moving to tighten laws by adding new regulations for opting out. But no one does
enough to limit exemptions.
Parents ought to be able to opt out only for limited medical or religious reasons. But personal opinions? Not
good enough. Everyone enjoys the life-saving benefits vaccines provide, but they’ll exist only as long as everyone
shares in the risks.

A．a small number of measles cases can start a dangerous trend B．the outbreak of measles attracts the public attention C．anti-vaccine movement has its medical reasons D．information about measles spreads quickly

高考试题二
体裁 说明文 话题 参加群体锻炼对健康的好处 词数 386 难度 ★★★★☆ 建议时间 7分钟 （2015·福建卷)Group exercise is one of the most effective ways to improve physical fitness and sustain(保持) a healthy lifestyle. Group exercise is challenging，yet fun and empowering！Of course everyone knows that exercise is good for the body. However，studies have shown that when exercise is performed in groups，it’s not only great for improving physical health but for psychological health. It’s an opportunity to be social，release endorphins(内啡肽)，and improve your strength. Additionally，group exercise creates a community feel and the shared common goal motivates participants to work hard. The instrumental support of taking on a fitness journey with others proves more effective than going to the gym alone.zx%xk
Another beneficial aspect of group exercise is the informational support participants receive from the instructor. Many people fear the gym because they feel lost and don’t want to embarrass themselves. If you feel you can relate，then group training is an even better option for you. It’s a great opportunity to learn more about fitness through the clear instruction and supervision(监管) of a fitness instructor. If you’re tired of wandering around the gym wasting time and becoming bored，you can attend an upbeat group fitness class that’ll keep your workout on track. Don’t let fitness frighten you!
If you’re serious about wanting to live a healthy lifestyle，it’s extremely important to surround yourself with people who’ll provide you with the proper emotional support. I wouldn’t scold anyone for deciding to party on weekends and in turn I wouldn’t expect anyone to give offence to me for focusing on my health. Surround yourself with people who uplift，encourage and understand you！Make fitness even more fun by trying something new or any group fitness class，with a friend. Plan to go for a jog together. Then try a fun healthy restaurant or fresh juice bar！Fitness can be both fun and social!
Surrounding yourself with people who’ll provide you with respect support can be very beneficial while working towards reaching health and fitness goals. First，decide to do it for yourself and work towards staying positive. Then make sure the people you surround yourself with are supportive. Don’t let negativity ruin your motivation.
