Muscle tissue also tends to keep vaccine reactions localized at the injection site. If certain vaccines are injected into fat tissue, the chance of irritation and side effect increases because fat tissue has poor blood supply, leading to poor absorption of some vaccine components. Vaccines must be given in a muscle to avoid widespread side effect.
Yet another deciding factor in vaccine administration location is the size of the muscle as well as convenience.
What may the underlined word in the sixth paragraph mean?
A.Common feeling of sorrow. | B.Abnormal sensitivity to stimulation. |
C.Terrible wound in the muscle. | D.Absorption of vaccine components. |

【推荐2】A trial project by the Montreal Children’s Hospital suggested that the use of medical hypnosis (催眠) can reduce pain and anxiety in patients. The project also resulted in a reduction in the amount of medicines used to perform medical-imaging imaging (医学影像) procedures.
“During the examination children don’t move. It works perfectly. It’s amazing,” said Johanne L’Ecuyer, a medical-imaging technologist at the hospital.
The project was inspired by a French team from Rouen University Hospital Centre where examinations are done under hypnosis instead of general anesthesia (麻醉).
A French medical-imaging technologist-also a hypnotist-was invited to train a few members in the medical-imaging department of the children’s hospital. In all, 80 examinations were conducted for the project between January and September, 2019, focusing on the imaging procedures that would cause anxiety.
Hypnosis is not a state of sleep: It is rather a modified (改变) state of consciousness. The technologist will guide the patient to this modified state-an imaginary world that will disassociate itself more and more from the procedure that follows.
“The technologist must build up a story with the patient,” Ms. L’Ecuyer said. “The patient is left with the power to choose what he wants to talk about. Do you play sports? Do you like going to the beach? We establish a subject that we will discuss throughout the procedure”.
Everything that happens next during the procedure must be related to this story-an injection (注射) becomes the bite of an insect: the heat on the skin becomes the sensation of the sun and a machine that rings becomes a police car passing nearby.
“The important thing is that the technologist associates what is happening outside the patient’s body with what the patient sees in his head.” Ms. L’Ecuyer said. “It requires creativity on the part of the technologist, imagination, a lot of patience and kindness.”
“The procedure appealed to the staff a lot when it was introduced in January. It spread like wildfire that someone from France was here to train the technologists,” Ms. L’Ecuyer said. She added that she had a line of staff at her door wanting to take the training.
1. One of the results produced by the trail project is ______.A.less use of certain medicines | B.a better understanding of children |
C.new medical-imaging technology | D.an improved reputation of the hospital |
A.creating a perfect world for patients | B.forcing patients into a state of deep sleep |
C.putting patients into an unconscious state | D.leading patients’ consciousness away from reality |
【推荐3】More than 60 years and almost 1,200 donations later, Harrison, whose blood contains an antibody (抗体) that has saved the lives of 2.4 million babies from miscarriages (流产), retired as a blood donor on May 11. Harrison’s blood is valuable because he naturally produces Rh-negative blood, which contains Rh-positive antibodies. His blood has been used to create anti-D in Australia since 1967.
“Every bottle of anti-D ever made in Australia has James in it,” Robyn Barlow, the Rh program director told the Sydney Morning Herald. “It’s an amazing thing. He has saved millions of babies. I cry just thinking about it.” Since then, Harrison has donated between 500 and 800 milliliters of blood almost every week. “I’d keep going if they let me,” Harrison told the Herald. His doctors said it was time to stop the donations. They had already extended the age limit for blood donations for him, and they’re cutting him off now to protect his health.
What can we learn from the underlined sentence in paragraph 3?A.Robyn Barlow was sad because millions of babies suffer from blood disease. |
B.Robyn Barlow was worried because Harrison may die of losing too much blood. |
C.Robyn Barlow was moved by Harrison’s donations. |
D.Robyn Barlow was frightened by Harrison’s crazy behavior. |
【推荐1】Teens and younger children are reading a lot less for fun, according to a Common Sense Media report published Monday.
While the decline over the past decade is steep for teen readers, some data in the report shows that reading remains a big part of many children’s lives, and indicates how parents might help encourage more reading.
According to the report’s key findings, “the proportion (比例) who say they ‘hardly ever’ read for fun has gone from 8 percent of 13-year-olds and 9 percent of 17-year-olds in 1984 to 22 percent and 27 percent respectively today.”
The report data shows that pleasure reading levels for younger children, ages 2—8, remain largely the same. But the amount of time spent in reading each session has declined, from closer to an hour or more to closer to a half hour per session.
When it comes to technology and reading, the report does little to counsel (建议) parents looking for data about the effect of e-readers and tablets on reading. It does point out that many parents still limit electronic reading, mainly due to concerns about increased screen time.
The most hopeful data shared in the report shows clear evidence of parents serving as examples and important guides for their kids when it comes to reading. Data shows that kids and teens who do read frequently, compared to infrequent readers, have more books in the home, more books purchased for them, parents who read more often, and parents who set aside time for them to read.
As the end of school approaches, and school vacation reading lists loom (逼近) ahead, parents might take this chance to step in and make their own summer reading list and plan a family trip to the library or bookstore.
How should parents encourage their children to read more?A.Act as role models for them. | B.Ask them to write book reports. |
C.Set up reading groups for them. | D.Talk with their reading class teachers. |
【推荐2】George Prochnik would like the world to put a sock in it. He makes his case in a new book, listenning for Meaning in a World of Noise, here he explains himself (using his indoor voice):
“We’ve become so accustomed to noise, there’s about almost a deep prejudice against the idea that silence might be beneficial. If you tell someone to be quiet, you sound like an old man. But it’s never been more important to find continuing quiet. Silence focuses us, improves our health, and is a key to lasting peace and satisfaction.”
“We need to excite people about the sounds you start to hear if you merely quiet things down a little. During a Japanese tea ceremony, the smallest sounds becomes a kind of art—the spoons making a light ringing sound on a bowl, the edges of a kimono(和服)brushing against the floor.”
“Dear people are very attentive(专注的)in almost every aspect of life. If two deaf people are walking together, using sign language, they constantly watch out for each other and protect each other by paying steady attention to the other. They are connected yet also fully aware of their surroundings. Even deaf teenagers! We in the hearing world can learn from them. If we remove the powerful blasts(一阵阵)of noise, we become aware of an extraordinarily rich world around us—of little soft sounds and the sound of footsteps, of bird songs and ice cracking(开裂声). It’s astonishing how beautiful things sound when you can really listen. ”
What does the phrase “to put a sock in it” in Paragraph 1 probably mean?
A.to be quiet | B.to be colorful |
C.to be full of love | D.to be attentive to someone |

【推荐1】By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing. ” she said, “but the type of phytoplankton is changing.”
And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”
What does the underlined word “vulnerable” in Paragraph 3 probably mean?
A.Sensitive. |
B.Beneficial. |
C.Significant. |
D.Unnoticeable. |

【推荐3】Examining the classroom practices of National Teacher of the Year winners and finalists, the study, by Michigan State University scholars, suggests successful educators aren’t afraid to push the boundaries by adding real world, cross-disciplinary(跨学科的)themes into their lessons.
The study, published online in the journal Teachers College Record, is one of the first in depth investigations of how teachers use creativity in the classroom.
“The best teachers are taking their own creative interests – from rap music to cooking to kickboxing – and are finding ways to include these into the curriculum,” said Danah Henriksen, lead author of the study. “They’re bringing together different subject matters and finding areas of connections so students can learn both in interesting ways.”
America’s test-driven educational policy, Henriksen argues, has impeded creativity in teaching and learning. Many teachers today struggle to balance high-stakes(高风险)testing and responsibility to act flexibly and independently in their classrooms.
“I think that there’s a lot of fear.” one of the award-winning teachers says in the study, “And when teachers are teaching in fear, they take few risks, for they have to consider exams and academic performance.”
The findings have major implications(含意)for teaching and learning. Teachers’ unique creative interests should be brought into classroom lessons, along with arts and music across varied academic content. Teacher education programs and professiona1 development courses should include a focus on real world. Administrators and policymakers should support opportunities for teachers to take creative and intellectua1 risks in their work.
“If we want teachers to be creative, we need to provide them with opportunities to bring those outside interests into their professional life,” said Mishra, study co-author and MSU professor of educational psychology and educational technology. “The point is to find what works for you, what is your passion and interest and how can you put that into what your students are learning. Finally, we teach who we are. That’s the most powerful finding.”
What does the underlined word “impeded” in paragraph 4 mean?A.admitted. |
