2 . In early July, FDA granted traditional full approval of Leqembi for the treatment of Alzheimer’s disease (AD). This is the first approved medication proven to slow the progression of AD’s clinical symptoms. A phase three trial among 50- to 90-year-old patients with early AD showed that it can do so by about 27% over an 18-month period. While we cannot extrapolate (推断) beyond 18 months, this represents about a six-month delay in progression of AD symptoms.

A second disease-slowing drug, donanemab, has recently shown similar effects and may get FDA approval by the end of the year.The development of Leqembi is a notable success for medical science in that a disease previously impervious to any disease-modifying medical intervention now has an available, effective treatment. However, paraphrasing Winston Churchill, this is not the beginning of the end but the end of the beginning. The drug does not reverse disease symptoms or prevent progression, it slows progression. And there are considerations that make it inappropriate for many patients with AD. It does, however, lay the groundwork for future AD medications that could alleviate (减轻) suffering from this devastating disease for generations to come.

An important factor for new drugs is their cost. Leqembi’s price tag is $26,500 per year—much more than the current symptomatic medications for AD but comparable or less expensive than new medications for other conditions, for example multiple sclerosis or ALS.

Medicare has announced that it will provide coverage for this medication, although it is requiring that physicians perform certain clinical measures and enter the patient’s data in a registry in order for the drug to be covered, which will increase physician and patient burdens. What’s more, traditional Medicare only covers 80% of outpatient costs, so for those patients without supplemental insurance, a 20% copay for the drug and required MRI scans (核磁共振扫描) might amount to up to $10,000 or more per year out of pocket, but still only a fraction of the cost of a year of in a nursing home.

1. What can we learn from the first two paragraph?

A．Leqembi can make a six-month delay of AD’s symptoms over a two-year period.

B．To some degree, Leqembi is effective to slow the progression of AD symptoms.

C．Both donanemab and Leqembi have got FDA approval.

D．The drug is appropriate for any patient with AD.

2. The underlined sentence in Paragraph 2 means _____ in the passage.

A．although the new drug has undergone trials, it is still not effective enough

B．though Leqembi can slow the progression of AD’s symptoms, we still have a long way to go

C．the research of the Leqembi will come to an end

D．some others problems related to the the medicine have been caused

3. Leqembi’s price is _____ according to the passage.

A．much cheaper than other medications for AD

B．much more than current medications for other conditions

C．affordable to almost every patient

D．cheaper than new medications for ALS

4. Medicare will provide coverage for this medication on condition that _____.

A．physician and patient burdens are increased

B．patients do not have supplemental insurance

C．patient’s data is registered and clinical measures are carried out by doctors

D．patients pay the cost of a year of in a nursing home

3 . While it is known that parents control the dietary choices of their children during early childhood, the increasing independence experienced during adolescence brings with it more freedom when it comes to food choices. This time of life also brings enormous physical and emotional changes in a young person, which is often associated with an increase in comfort eating, or eating as a means to relieve stress. A recent study investigates how various feeding practices used by parents impact the emotional eating behavior of adolescents.

The initial study was conducted in 2017 with 218 families. Additionally, data collected in 2013 were also available. One parent from each family completed the Child Feeding Questionnaire, as well as the Child Feeding Practices Questionnaire, and both adolescent and parent completed the Dutch Eating Behavior Questionnaire. The adolescent’s body weight and height were measured by researchers. The four years between 2013 — 2017 covered the years from late childhood to mid-teens.

The study found that when parents used food as a reward, or restricted and monitored an adolescent’s access to food, this was associated with an increased tendency by the adolescent to use emotional eating as a strategy to deal with their emotions. On the other hand, involving a child in meal preparations had the opposite effect — it was associated with higher levels of emotional regulation and lower levels of emotional eating in the adolescent participants.

Additionally, the researchers found a negative link between the extent to which parents restrained (克制) their own eating behavior and the use of emotional eating by their adolescent children. This means that the more a parent limited his or her own consumption of food for the purpose of health or dietary goals, the less the adolescent child used emotional eating as a means of regulating his or her own emotions.

According to study lead author Joanna Klosowska, restrictive parenting was most damaging, whereas restrained eating by the parent seemed to be the most beneficial. “Additional research is required to understand the way in which restrained eating demonstrated by a parent impacts the emotional eating of a child,” said Klosowska.

1. What does the underlined word “it” in paragraph 1 refer to?

A．Parents’ dietary choice.	B．Parents’ eating behavior.
C．Children’s way of relieving stress.	D．Children’s increasing independence.

2. What did the researchers do in the study?

A．They studied parents’ body weight and height.

B．They investigated children’s eating behaviors.

C．They interviewed parents about their emotional health.

D．They assessed parents’ understanding of children’s care needs.

3. What did the study find?

A．Restrained eating by parents is bad for their children.

B．Emotional eating by teens is influenced by their parents.

C．Parents seldom engage their children in family meal preparations.

D．Using food as a reward can help children form good eating habits.

4. What will future research focus on according to Klosowska?

A．Factors resulting in parents’ and adolescents’ food choices.

B．The underlying logic behind parents’ restrictive parenting.

C．What effect emotional eating can generate on children’s health.

D．How parents’ restrained eating influences children’s emotional eating.

4 . It is challenging to teach children about seasonal foods in a modern-day grocery store (杂货店). Having lots of choices of fresh produce from all around the world means that a sense of the seasons is lost. That’s why I like being part of a Community Supported Agriculture (CSA) program. Every week I receive a share of vegetables that comes from a nearby farm. I do not know ahead of time what I’m getting, nor do I have any say on what comes home; I take whatever was harvested earlier that same day, based on the week’s weather conditions, and use them to the best of my ability.

My kids have had a good knowledge of the supply of certain vegetables throughout the harvesting season. They know what it’s like to eat a lot of asparagus (芦笋) until they’re sick of it, only to move on to dark greens and leafy salads, then eggplants, and tomatoes, and finally the root vegetables that mark the arrival of cold weather.

The funny thing is, when you’ve eaten a ton of something for a few weeks, you’re ready to move on to the next crop (作物) and leave the other behind, but when its time comes the following year, the expectation will return. In this way, a CSA share creates excitement at vegetables that can’t be felt when everything can be bought all the time, as it is in a grocery store.

A farmers’ market can offer similar lessons in seasonality to a CSA, but it differs in that you have more choices about what you buy. A CSA share, however, only offers few kinds of vegetables and sometimes fruits, forcing you to work out ways of using them up. I enjoy this challenge because it tests my cooking skills and introduces my family to new and unusual vegetables. What’s more, it is glad to know I’m supporting local farmers by eating what they want to grow, not just what I’m used to eating.

1. What is special about the vegetables offered by the CSA program?

A．They are free.

B．They are cheap.

C．They can’t be found in local grocery stores.

D．They make the author full of expectations.

2. What does the author think of the CSA share?

A．It provides enough supply of vegetables.

B．It makes people choose vegetables freely.

C．It keeps people’s excitement for vegetables.

D．It makes people become sick of eating vegetables.

3. What does the author say about the program in the last paragraph?

A．It encourages him to support local farmers.

B．It helps him learn about the community.

C．It gives people more choices of foods.

D．It causes local farmers a lot of stress.

4. What is the best title for the text?

A．Local food is becoming more popular

B．The CSA program is making a difference

C．People are encouraged to experience farm life

D．Naturally grown food improves people’s health

Does music have the power to help us sleep better? According to a recent research, it does. Using an experiment in     1     62 young adults listened to five nights of happy music, five nights of sad music, and five nights of pink noise, researchers found that people reported sleeping better and feeling more positive    2     (little) negative, and more satisfied with life on mornings after listening to music while falling asleep.

These benefits    3     (find) when comparing listening to music with listening to pink noise. Given that pink noise is thought    4     (help) deepen sleep, the additional beneficial effects of music beyond pink noise are    5     (impress).

Does the type of music matter? There were no    6     (difference) in sleep quality and well-being when comparing happy and sad music.     7     (important), all of the music was selected with the goal of being calm and relaxing. And although this study focused    8     young adults, other research has found effects on older adults, suggesting music might be helpful across the lifespan.

Why would music have these beneficial effects? So far, little research     9     (test) the reasons why music improves sleep quality but suggested reasons include relaxation, a distraction from unwanted thoughts,     10     masking of unpleasant background noise.

6 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Every student can learn rope jumping. You can jump alone or    1     your classmates. You can also help turn a long rope for many others     2     (jump) over one at a time. If you jump alone, you will need a short rope and it will be just enough for your     3     (high). Try ropes of different lengths until you find a right one for your size.

A rope should be turned     4     (slow). It must also be turned high enough to let you jump freely and safely,     5     needs careful timing. In rope jumping, timing means    6     (turn) the rope slowly enough for you to jump over at the right time without its striking     7     (you) feet.

When you jump rope, your heart beats     8     (fast) and your face has a healthy color. But if you jump too many times at first, you will get     9     (tire). You must learn when to stop for a rest before you jump again. If you practice and practice, you can increase     10     number of times you jump without resting. Jumping rope strengthens the upper and lower body and burns a lot of calories in a short time.

7 . In the Chinese reality series “Forget Me Not Café,” five seniors with Alzheimer’s disease(阿尔茨海默症) work as restaurant servers and are enthusiastic about socializing and living a fulfilling life despite their condition. After watching the show, three Singapore Institute of Technology students, Nashita Fatima, Chen Zihan and Fang Qian, were deeply inspired by their efforts to raise awareness of the condition.

The three have decided to play their part in helping people with Alzheimer’s disease. They signed up as participants in the global Huawei ICT(Information and Communication Technology) competition to create smart glasses called Forever-Smart Glasses.

This eyewear is designed to help people with Alzheimer’s disease recognize their loved ones. Powered by Huawei Cloud, the glasses are complemented(补充) by an app called YourHelper. It has a built-in GPS positioning system to track the whereabouts of the elderly. Family warnings are automatically sent when the wearer gets lost or is far away from home.

For their project, this all-female group won the grand prize and the TECH4ALL Social Contribution Award in the Global Final of the Huawei ICT Competition 2019-2020. The Huawei ICT Competition is an annual international competition aimed at stimulating innovation for students in higher education institutions by challenging their knowledge of ICT.

Team leader Fang Qian, 20, said: “During our research, we found that there are many great AIoT products that improve people’s quality of life, but they are not focused on the elderly.

“We were motivated by the show and smart glasses technology to create a wearable AIoT device so that Alzheimer’s patients won’t forget their loved ones easily.”

Nicholas Ma, CEO of Huawei International, said of the winning team from Singapore: “It is important to train young talent to develop a sustainable and comprehensive mindset. We will continue working with local partners and institutions of higher education to build talent alliances(联盟), spread the value of talent and work towards becoming a smart nation, creating a healthy ICT talent ecosystem.”

1. Why is “Forget Me Not Cafe” mentioned in paragraph 1?

A．To praise the innovation(创新) of the reality series.

B．To introduce the active life of Alzheimer’s patients.

C．To stress the popularity of the reality series with the audience.

8 . My friend James did some first-aid training last week to learn the fundamentals of the CPR. And he asked if I’d ever done the same.

“Yes,” I said, “…and no.”

Because, yes, I’ve attended several resuscitation (复苏) sessions over the years.     1     In fact, despite being shown all the key information at various points in my career, I don’t think I can remember any of it now.

What’s the problem? Every time I’ve had this type of training, it’s been a perfectly good opportunity to learn: an important topic, taught well, in a focused environment, with plenty to see, hear and do. I’ve always taken it seriously, too, and been focused. And I’ve always come away with a wealth of information.     2    

Here’s what I should have done — and what you can do now — to make sure any training doesn’t go to waste.

•     3     You might be surprised to find that you’ve got some foundations of knowledge to build on. Pre-testing sparks your curiosity and puts you in a frame of mind to remember.

• Challenge your recall later.     4     If it’s hard to remember, but just about possible with effort, then that’s perfect. You need that little bit of struggle to start embedding (把……嵌入) information in your brain.

• Keep coming back. Put a note in your diary to test yourself again in a week, then ten days after that, then a month on…leaving longer gaps between checks.     5    

Talking to James has inspired me to book myself onto yet another CPR course. But this time I’m determined to do it right. Remember that it’s the next day when the real training begins.

A．Test yourself before you start.

B．Wait a day, then see how much you still know.

C．Stay curious about what you are eager to know.

D．All the basic information has stuck in your mind.

E．But no, I don’t exactly feel “trained” to save lives.

F．Yet virtually nothing has ever made it to my longterm memory.

G．Use the questions you wrote on the day to keep challenging yourself.

9 . Many of us are familiar with the anxiety that can consume us ahead of speaking or performing in public. Throats run dry, sweat drops, and it can feel like everyone hears your quickly beating heart. But scientists wondered: Is the anxiety driving the heart to beat faster or could an increased heart rate cause anxiety?

A new study published today explores this link in mice, showing that speeding up a mouse’s heart rate made otherwise calm animals act more anxious. The finding indicates heart activity can influence mental state — and finding ways to lower heart rate may be a way to treat mood disorders such as anxiety and depression.

The research team introduced ChRmine (泵状光敏感通道蛋白) into heart muscle cells of live mice whose torsos (躯干) were fitted with a vest equipped with a micro light-emitting bulb (电灯泡). Light from the bulb then shined the skin of the mice to stimulate ChRmine within the cells. The result: a small pacemaker made the animals’ hearts beat faster.

Because the team could just turn the light on and off, “we were now able to control heart rates using this wearable,” said Ritchie Chen, a bioengineer at Stanford and an author of the study.

In the future, Deisseroth and his team want to make periods longer than used in the current experiment to see whether increased heart rate over weeks or months can lead to an increase or worsening of anxiety or depression like behaviors.

If the findings can be copied in other settings, particularly with people, they could have potentials for treating mental health conditions. Current medicines are not foolproof and often take months to work. Going through the heart may be a quicker, more effective alternative. “Operating the heart is much easier than operating the brain,” Gogolla says. “We may actually unlock new treatment strategies for patients with anxiety or depressive disorder.”

1. What’s the purpose of the first paragraph?

A．To prove previous theories.	B．To show the puzzle of the scientists.
C．To highlight the importance of the findings.	D．To explain the background knowledge of the study.

2. Why is the bulb used in the experiment?

A．To see more clearly.	B．To relieve anxiety.
C．To stimulate ChRmine in the cells.	D．To rid the fear of mice.

3. What does Gogolla suggest?

A．Clarifying the purpose of the study.	B．Realizing the potential of the findings.
C．Conducting research on human beings only.	D．Carrying out new strategies in the experiment.

4. What is the best title for the text?

A．New Dawn on Mood Disorders	B．Links between the Heart and the Brain
C．Mice Are More Sensitive than Human	D．A Newly-designed Vest Is on Sale

10 . Your immune system is the body’s personal army.     1     A healthy immune system can defeat invading disease-causing germs(病菌), such as bacteria, viruses, parasites-as well as cancer cells-while protecting healthy tissue.

    2     The body’s natural barriers against disease-causing germs-for example, our skin, the hairs in our nose, and the acid in our stomachs-are part of our innate immune systems. Innate immunity is the immune system that you inherit and it’s active as soon as you’re born.     3     Instead, it attacks broadly, which is why it is unable to get rid of all germs.

The immune system also learns things-this is called adaptive immunity. When your immune system is exposed to a new germ for the first time, it responds by trying to fight it off-which means you may become sick.     4    

Experience makes your immune system stronger. The first time your body comes into contact with a certain type of germ, your immune system response may take a while. You might need several days to make and use all the germ-fighting parts you need to get rid of your infection. It takes time to hack the germ’s code and destroy it.     5     Mission accomplished!

A．It does not recognize specific bacteria or viruses.

B．It releases white blood cells and other chemicals that destroy these threats.

C．It is a vast and complex interconnected network of many different organs, cells and proteins that work together to protect the body from illness.

D．The main feature of the innate immune system is to respond quickly, which can lead to fever.

E．But afterward, the immune cells will remember the invader and be better equipped to fight it, should it return.

F．The system has two types of response: innate(先天性反应) and adaptive.

G．If you come across that same germ later on, your body will remember and fight it off faster, so you can get over the infection and feel better.
