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.

1. The first two paragraphs suggest that ____________.
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
2. Herd immunity works well when ____________.
A.exemptions are allowed
B.several vaccines are used together
C.the whole neighborhood is involved in
D.new regulations are added to the state laws
3. What is the main reason for the comeback of measles?
A.The overuse of vaccine.
B.The lack of medical care.
C.The features of measles itself.
D.The vaccine opt-outs of some people.
4. What is the purpose of the passage?
A.To introduce the idea of exemption.
B.To discuss methods to cure measles.
C.To stress the importance of vaccination.
D.To appeal for equal rights in medical treatment.

文章大意:本文是一篇说明文。文章通过几项不同实验结果表明甜味剂增加癌症风险这是不确定的。

【推荐1】Sweeteners(甜味剂)are consumed by millions every day in products like diet soda, partly as a way to avoid weight gain from sugar-but how healthy these substitutes are has long been controversial.

To assess the cancer risk of sweeteners, researchers analysed the data of more than 100,000 people in France who self-reported their diet, lifestyle and medical history in intervals between 2009-2021.

“The participants who consumed the largest amount of sweeteners, beyond the middle amount, had an increased cancer risk of 13 percent compared to non-consumers,” said Mathilde Touvier, research director at France’s INSERM institute.

The study said that a higher cancer risk was particularly seen with sweeteners aspartame(阿巴斯甜)and acesulfame potassium(安赛蜜), used in many soft drinks including Coke Zero. Soft drinks accounted for more than half of the artificial sweeteners consumed, while table-top sweeteners represented 29 percent.

The study found that “higher risks were observed for breast cancer and obesity-related cancers”. Touvier said “we cannot totally exclude biases linked to the lifestyle of consumers”, calling for further research to confirm the study’s results.

The US National Cancer Institute and Cancer Research UK both say that sweeteners do not cause cancer, and they have been authorised for use by the European Food Safety Authority. Michael Jones of The Institute of Cancer Research, London said that the link reported in the study was “not proof that artificial sweeteners cause cancer”.

He said the findings could suggest that “cancer risk may be raised in the type of person who uses artificial sweetener rather than the sweetener itself.”

Thursday’s findings also do not mean consumers should rush back to sugary drinks-a former study found that they were also linked to a higher risk of several cancer types.

1. Why do people prefer to choose products with sweeteners?
A.These products are cheap in price.
B.Sweeteners used in them are totally safe.
C.Sweeteners in them help people not to put on weight.
D.These products have better taste than those with sugar.
2. What can we learn about the study?
A.Scientists mainly focus on sweeteners used in soft drinks.
B.The findings were not supported by all scientists and institutes.
C.The data was collected on a large scale for no more than ten years.
D.The intake of sweeteners can lead to 13%participants facing cancer risk.
3. Which of the following would Michael Jones agree with?
A.Artificial sweeteners shouldn’t be used cautiously.
B.Drinking much diet soda will bring in lower risk of cancer.
C.People should take in food with sugar instead of sweeteners.
D.Cancer risk may have much to do with the lifestyle of people.
4. What is the best title for the text?
A.Sweeteners increasing cancer risk: not for sureB.The future of employing artificial sweeteners
C.Time to rush back to sugary drinksD.A large-scale study on sweeteners

文章大意:本文是一篇记叙文。文章讲述了Mike Mushaw的骨髓与一位患有一种罕见免疫缺陷疾病且只有五个月大的小女孩配对成功。他不仅救了这个小女孩,并与小女孩的一家建立了深厚的友谊。

【推荐2】Mike Mushaw joined the national bone marrow registry (骨髓登记) three years ago by chance. Six months later, he got a call. The 21-year-old football player's bone marrow matched a patient in Virginia. Mushaw gave a second thought to the donation, because apart from some risks, he never knew whether his donation worked.

“Finally I said yes,” Mushaw told the journalist. “Once they took my blood, I thought, ‘All right, this is real. This is going to happen.’”

Mushaw didn't know it at the time, but his donation would go to a five-month-old girl named Eleanor who was sick with a rare disease diagnosed when she was only three months old. Days and weeks passing, her condition had become more dire.

“Eleanor was going to die without a bone marrow transplant,” her mother, Jessica, said. “The choices were to either get a transplant or die early. Luckily, Mushaw’s bone cured her.”

Mushaw didn't know any of this until months after his donation. About six months after the procedure, Eleanor's parents sent him an e-mail to thank him for his selfless love.

Their surprising connection was beginning. Mushaw kept checking on her progress. Eleanor focused her attention on him, too, by watching his football games on TV. In August, Mushaw invited her family to drive from Virginia to Connecticut to meet at one of his games. They had a good time together.

In January, Mushaw reunited with Eleanor, this time in Virginia, to celebrate her birthday. It will likely be first of many celebrations together. “As a parent, it feels really great to watch someone love your kid as much as you do,” Jessica says. “We were two complete strangers, and now we've become such a big part of each other's lives.”

1. Why did Mushaw hesitate at first?
A.He was a football player.B.He would face some danger.
C.He knew it wouldn't work at all.D.He didn't know whether his risks were worthy.
2. What does the underlined word “dire” in paragraph 3 mean?
A.Serious.B.Complicated.C.Relieved.D.Hopeful.
3. Which of the following best describes Mushaw?
A.Kind but hesitant.B.Active and confident.
C.Worried but energetic.D.Selfless and considerate.
4. What can we learn through Mushaw's story?
A.Why health matters.B.Never make excuses.
C.How to be a good person.D.Love brings people together.

【推荐3】Two 5-year-old girls, best friends, held hands in Tolson’s office at Van Ness Elementary School in Washington, D.C., one saying she didn’t feel well. Tolson, the school nurse, asked, “How long has your stomach been hurting?” “It just started,” she said.

The other one said her head hurt last night, too. Tolson knew she had a history of fevers, so she checked her temperature and asked her what she ate, whether she went to the bathroom, and whether her head still hurt. It could be that these two little girls that went to Tolson’s office were fine. Or maybe they had mental problems. And that is what school nurses have to judge every day.

School nurses generally get very little training when it comes to mental health. Mazyck said she herself was astounded when she was a school nurse. She saw upset, anxiety, sadness and students who didn’t even know what to do to calm themselves down. She never expected these. So Mazyck went back to school for a graduate degree in counseling (咨询) and now she focuses on getting nurses more training in mental health.

Sharon Stephan, who co-directs the National Center for School Mental Health at the University of Maryland, tells nurses there are two simple questions to ask themselves to see if a child needs help:

Is the student acting or behaving differently than he/she was before?

Is the student somehow far outside the norm (标准) of what you would expect?

The only time everyone pays attention is when there’s a tragedy(悲剧), like a school shooting. However, we actually can catch the students who might harm others and recognize the students who might want to kill themselves.

Mental health is ranked one of the top problems all school nurses deal with, and school nurses need to be better at it.

1. Why does the author mention the two little girls?
A.To show school nurses do a difficult job.
B.To show the importance of school nurses.
C.To show school nurses need much patience.
D.To show the importance of students’ health.
2. What does the underlined word “astounded” in the third paragraph mean?
A.Tired.B.Troubled.
C.Shocked.D.Embarrassed.
3. Why did Mazyck go back to school?
A.To give nurses more training in mental health.
B.To find school students with mental problems.
C.To learn what mental problems students may have.
D.To improve her skills of dealing with mental health.
4. What can we learn from the last but one paragraph?
A.There are too many kids in need of help.
B.Something tragic often happens at school.
C.Students’ mental health is always ignored.
D.It’s hard to find students with mental problems.
