1、高中英语阅读理解汇编之说明文阅读理解专练说明文8篇Passage 1(2017北京,C)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 movemen

2、t 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

3、 nation as a whole, everyone is protected. This is called“herd immunity”, which protects the people who get hurt easily, including those who cant be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesnt work.But herd immunity works only when nearly

4、the whole herd joins in. When some refuse vaccination and seek a free ride, immunity breaks down and everyone is in even bigger danger.Thats exactly what is happening in small neighborhoods around the country from Orange County, California, where 22 measles cases were reported this month, to Brookly

5、n, 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

6、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 o

But w

20、here are we doing all of this waiting, and what does it mean to an impatient society like ours?To understand the issue, lets take a look at three types of “waits”.The very purest form of waiting is the Watched-Pot Wait. It is without doubt the most annoying of all. Take filling up the kitchen sink(洗

21、碗池)as an example. There is absolutely nothing you can do while this is going on but keep both eyes fixed on the sink until its full. During these waits, the brain slips away from the body and wanders about until the water runs over the edge of the counter and onto your socks. This kind of wait makes

22、 the waiter helpless and mindless.A cousin to the Watched-Pot Wait is the Forced Wait. This one requires a bit of discipline. Properly preparing packaged noodle soup requires a Forced Wait. Directions are very specific.“Bring three cups of water to boil, add mix, simmer three minutes, remove from he

23、at, let stand five minutes.”I have my doubts that anyone has actually followed the procedures strictly. After all, Forced Waiting requires patience.Perhaps the most powerful type of waiting is the Lucky-Break Wait. This type of wait is unusual in that it is for the most part voluntary. Unlike the Fo

24、rced Wait, which is also voluntary, waiting for your lucky break does not necessarily mean that it will happen.Turning ones life into a waiting game requires faith and hope, and is strictly for the optimists among us. On the surface it seems as ridiculous as following the directions on soup mixes, b

25、ut the Lucky-Break Wait well serves those who are willing to do it. As long as one doesnt come to rely on it, wishing for a few good things to happen never hurts anybody.We certainly do spend a good deal of our time waiting. The next time youre standing at the sink waiting for it to fill while cooki

26、ng noodle soup that youll have to eat until a large bag of cash falls out of the sky, dont be desperate. Youre probably just as busy as the next guy.1.While doing a Watched-Pot Wait, we tend to.A.keep ourselves busyB.get absent-mindedC.grow anxiousD.stay focused2.What is the difference between the F

27、orced Wait and the Watched-Pot Wait?A.The Forced Wait requires some self-control.B.The Forced Wait makes people passive.C.The Watched-Pot Wait needs directions.D.The Watched-Pot Wait engages body and brain.3.What can we learn about the Lucky-Break Wait?A.It is less voluntary than the Forced Wait.B.I

28、t doesnt always bring the desired result.C.It is more fruitful than the Forced Wait.D.It doesnt give people faith and hope.4.What does the author advise us to do the next time we are waiting?A.Take it seriously.B.Dont rely on others.C.Do something else.D.Dont lose heart.5.The author supports his vie

29、w by.A.exploring various causes of “waits”B.describing detailed processes of “waits”C.analyzing different categories of “waits”D.revealing frustrating consequences of “waits”Passage 4(2017浙江,B)Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the Nati

30、onal Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school. How much s

31、leep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day!Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight

32、 hours. And guess what almost half of the surveyed kids said they do before bedtime?Watch TV.“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm dow
