26、Who are these people rushing by you in the street? More than 215 million people now call America “home”, but most of them can trace their families back to other parts of the world. If you look at the names on shop windows, you will see that Americans come from many different lands. The idea that these people, who once were strangers to the United States, have lost the customs and cultures of their original countries and have become “American” is really not true. In fact, what exists in America is more often a kind of “side-by-side” living in which groups of people from other countries often have kept many of their customs and habits. They join the general American society only in certain areas of their lives—such as in schools, business, and sports—but they keep many of their own native customs and manners socially and at home. This living “side-by-side” has both advantages and disadvantages. Sometimes it may cause disagreements to develop between groups whose ways of life are very different from one another. However, there are also great advantages that come from the variety of cultures brought by settlers from other lands. There is great freedom of choice among ideas and dress, food, and social customs in America. Everyone can find some part of his or her familiar world in the United States, in churches, music, food, national groups, or newspapers.

27、 Many of us know about Russia's Lake Baikal from our textbooks,or by listening to Chinese singer Li Jian's hit song,Lake Baikal.But over the past decade,the world's deepest freshwater lake has been in the spotlight for an extreme sport.
Each March since 2005,about 150 people from around the world sign up for the Baikal Ice Marathon.They come to explore the lake's breathtaking beauty and challenge themselves in unpredictable conditions.The 26-mile journey starts on the lake's eastern shore.In March,the ice is a meter thick and iron-hard.Runners cross this frozen surface,finishing on the western side of the lake.
Known as the"blue eye of Siberia",Lake Baikal has exceptionally clear waters.This means its ice is almost perfectly transparent（透明的）."Seen from above,a runner on the ice looks as if he or she is jogging through space,"The New York Times noted.
The landscape might be beautiful,but the weather is harsh.Strong winds blow across the lake and frostbite（冻伤）can occur within half an hour.Runners say the cold climate is what draws them.They want to test their limits."When you are in such an environment,you don't have cars around you,you don't have the noise around.I think these extreme races allow you to be alone with nature,"Alicja Barahona,a 64-year-old runner from the US,told ABC News.
The location offers some strange and unique characteristics for this marathon.The finish line is visible from the start,but the endless white offers no progress markers.The race also ends with little fanfare（喧闹）.Tourists crowding the ice are mostly addicted to taking photos and just ignore the runners.
For some runners,the absence of audience makes the race more challenging,because it's lonely.They must fight with themselves."You are alone on Baikal.It is your race.You are alone with yourself All you need to do is to defeat yourself,"Veronique Messina,a French runner,told the Telegraph.
【1】What do we know about the Baikal Ice Marathon?

B.There are many progress markers on the ice.
C.The runners are often disturbed by tourists.
D.The runners can see the finish line from the start.
【4】What is the most challenging in the race for Messina?

28、Scott and Daniel Harry are enjoying everyday tasks like shopping and washing for the first time following their move to an accommodation (住宿) support house in Kurwongbah, north of Brisbane last year.
Disability Services Queensland’s Strengthening Non-Government Organisations project provided an accommodation support model that would enable residents (居住者) like Daniel and Scott to live more independently.
The house is just one of many accommodation support services funded (资助) through the project. The five-bedroom house provides 24-hour care for up to four individuals with complex needs, including medical support. Care and staffing levels are varied and flexible, depending on each resident’s requirements.
Scott and Daniel, who have a severe form of Duchenne Muscular Dystrophy, require 24-hour support in all activities of daily living. Before they moved to the house, they lived with their family. Scott says living at home was difficult as it placed a physical and emotional strain (负担) on their parents who had to wake them several times each night to reposition them or place them on breathing machines.
“We were heavyhearted,” says Scott, who is planning to write a book about his life experiences. “But our parents now have a lot more time for themselves. We now manage ourselves on a day-to-day basis.”
Daniel is an enthusiastic gardener, taking care of his own vegetable garden. The men share the house with one other young man, and they go to rugby league games, meeting up with friends.
Leeding Care Australia provides the care service at Kurwongbah. Manager Lee Garniss says setting up the facilities (设施) has not been without its challenges.
“It is an unconventional model of care,” Lee says. “The home is Scott and Daniel’s home, however it is also a workplace for their support staff. Balancing these two requirements has been a challenge for all.”
“We have experienced a bit of a learning phase over the last twelve months. However, by working as a team we try our best to meet the needs of both residents and staff and I think we have achieved the right balance.”
【1】What do we know about the house Scott and Daniel live in now?
A．It was built by their parents.
B．It can accommodate four residents.
C．It belongs to a governmental project.
D．It’s located in the center of Brisbane.
【2】Why did Scott and Daniel’s parents wake up frequently at night?
A．To help them do exercise.
B．They were making a lot of noise.
C．To check on their breathing.
D．They were under emotional pressure.
【3】How did Scott feel while living with his parents?
A．A bit guilty.
B．Quite happy.
C．Very proud.
D．Slightly angry.
【4】What was a challenge while setting up the facilities?
A．Lack of fund.
B．No workplace.
C．Inexperienced staff members.
D．Satisfying both staff and residents’ needs.

A tiger at the Bronx Zoo in New York City has tested positive for the respiratory disease caused by the novel coronavirus, becoming the first known case of human-animal 【1】, the zoo's chief veterinarian said on Sunday.
Nadia, the 4-year-old Malayan tiger that tested positive, was 【2】 for the COVID-19 disease after 【3】 a dry cough along with three other tigers and three lions, the Wildlife Conservation Society, which manages the zoo, said in a statement.
All of the cats are expected to recover, it said. But officials believe this is a unique case because Nadia became sick after 【4】 to an asymptomatic zoo employee, Paul Calle, chief veterinarian at the Bronx Zoo, told Reuters.
Calle said they did not know which employee infected the tiger. "This is the first time that we have discovered that a person infects the animal and the animal gets sick," Calle said, adding that they planned to share the findings with other zoos and institutions. " I guess 【5】 we will all have a better understanding as a result.
While the other tigers and lions were also 【6】 symptoms, the zoo decided to test only Nadia because she was the sickest and had started to lose her appetite already, and they did not want to 【7】 all the cats to anesthesia(麻醉), Calle said.
Nadia 【8】 X-rays, an ultrasound(超声波) and blood tests to try to figure out what was making her sick . They decided to test for COVID-19 【9】 the surge in cases in New York City, the epicenter of the outbreak in the United States.The first tiger at the zoo, which has been shut since mid-March, began showing 【10】 of illness on March 27, according to the US Department of Agriculture National Veterinary Services Laboratories.

THE DECLARATION OF INDEPENDENCE
In Congress, July 4, 1776
When in the Course of human events, it becomes necessary for one people to dissolve the political bonds which have connected them with another, and to assume among the Powers of the earth, the separate and equal station to which the Laws of Nature and of Nature’s god entitle them, a decent respect to the opinions of mankind requires that they should d【1】 the causes which impel them to the separation.
We h【2】 these truths to be self-evident, that all men are created e【3】, that they are endowed by their Creator with certain unalienable R【4】, that among these are life, L【5】, and the pursuit of Happiness.
That to secure these rights, g 【6】 are instituted among Men, deriving their just powers from the consent of the governed.
That whenever any form of Government becomes destructive of these ends, it is the Right of the P 【7】 to alter or to abolish it, and to institute new government, l【8】 its foundation on such principles and organizing its powers in such f【9】, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience has shown, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariable the same Object, evinces a design to reduce them under absolute Despotism, it is their right, it is their d 【10】, to throw off such Government, and to provide new Guards for their future security.
36、Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.
Driving an electric car 【1】 to the protection of environment, or so the marketing departments of their makers would have you believe. Yet a report which analyzes car emissions presents a rather different picture. A battery-powered car recharged with 【2】 generated by coal-fired power stations, it found, is likely to be more harmful. It could cause more than three times as many deaths from pollution as a 【3】 petrol-driven vehicle.
The study was carried out by the University of Minnesota. The researchers estimated how levels of fine particulate matter (细颗粒物) and ground-level ozone — two important 【4】 of air pollution — would change when a car is powered by different ways.
It was no surprise that electric cars whose batteries were recharged with power from wind, solar or hydro-electric sources came out to be virtually free from harmful 【5】. They were estimated to cause 231 deaths over the course of a year, compared with 878 for petrol cars. Electric cars recharged with power from natural gas-fired stations were also a lot less harmful than petrol-driven ones, with 439 deaths. But if those same electric cars were recharged 【6】 by coal, they would be responsible for over 3,000 deaths.
Biofuels also caused more health problems than petrol. But diesel, which often 【7】 concern about pollution, is slightly cleaner than petrol. This is because the study assumes for all cars that emission-control technologies will be more widely used, especially particulate filters which have a remarkable effect on cleaning diesel 【8】. Diesel cars are also more 【9】 of fuel than petrol-driven ones.
Overall, the study shows that electric cars are cleaner than those traditional vehicles only if the power used to charge then is also clean. That is hardly a surprise, but the 【10】 of the difference is. How green electric cars really are, then, will depend mainly on where they are driven.

41、阅读下面短文，根据其内容写一篇60词左右的内容概要。
You may know that vitamin C is important to your body，but do you know that vitamin D is important to your body as well? Vitamin D has a significant role in calcium homeostasis(钙稳态) and metabolism(新陈代谢). It is sometimes called the “sunshine vitamin” because it’s produced in your skin in response to sunlight.
Vitamin D can help bones and muscles grow strong and healthy. If a person is short of vitamin D，he or she may have problems like rickets(佝偻病) and osteoporosis．Rickets is mainly found in children. Osteoporosis，the thinning of bone，is a common problem as people get older. Studies in these years have found that vitamin D may also have other uses. If someone is short of vitamin D, he may have heart problems or die from some cancers.
The easiest way to get vitamin D is from sunlight. But many people worry about getting skin cancer and skin damage from the sun. Also, even skin color has an influence. Darker skinned people get less vitamin D than lighter skinned people. Older people get less vitamin D than younger people. You can also get it from foods. Some food such as cheese and egg yolks (蛋黄) have some vitamin D．But most of vitamin D in the American diet comes from food like milk with the vitamin added.
Now more doctors are testing for vitamin D in their patients. However, some doctors worry that if people take too much vitamin D, it might be bad for their body. At the same time, skin doctors tell people to be careful with strong sunlight.
