In Sweden, McDonald's is building "bee hotels" on the back of its roadside billboards（广告牌） to help save the country's declining bee population. It launched the campaign together with outdoor advertising agency JCDecaux. Six large permanent wooden bee hotels first appeared on the back of a north-facing billboard in Jarfalla in September.
"Without pollination（授粉）from bees, a third of the food we eat would be threatened." McDonald's said. But it turns out that at least 30 percent of the country's wild bee population is endangered. A big problem is that they lack places to live in. Based on data released by Chalmers University of Technology, we know Sweden owns 274 species of bees, of which 37 species are bumblebees, and more than a third are in decline or face the risk of declining unless intervention would be made. Their natural habitats have been damaged by factors including the changes of agricultural activities and increased urbanization. Fortunately, most bees are able to survive in urban habitats, like the bee hotels.
Great efforts have been made by the company. On World Bee Day, May 20， it introduced "the world's smallest McDonald's"， Mc Hive, which could function as an actual beehive.
Designed by set designer Nicklas Nilsson himself, the creation was sold at auction（拍卖）for ＄10，000 at a charity fundraiser held for Ronald McDonald House Charities.
Beehives can be found on the rooftops of some McDonald's restaurants in Sweden, too. This took place in certain areas but is now followed by an increasing number of participants. More McDonald's restaurants are making an effort to improve the living conditions of wild bees by removing the grass around their restaurants to grow flowers and plants instead.
4. What does McDonald's do to help wild bees in Sweden？
A. Plant more trees.
B. Put up more billboards.
C. Provide shelters for bees.
D. Cooperate with other restaurants.
5. What do we know from the text？
A. Mc Hive was made on World Bee Day.
B. 30% of the bees in Sweden will go extinct.
C. Most McDonald's restaurants set beehives on their rooftops.
D. Human activities contribute to the decreasing of bee's population.
6. How does the author explain the importance of protecting bees？
A. By providing details. B. By giving examples.
C. By presenting results. D. By making comparison.
7. What can be the best title for the text？
A. Wild Bees in Danger B. McDonald's Bee Hotels
C. The Loss of Bee's Habitats D. The Conservation of Wild Bees

The cancer death rate in the U.S. fell by the most on record as advances in treatments for lung tumors（肿瘤）like video-assisted surgery helped prolong the lives of patients.
The death rate from cancer has been gradually declining for 26 years, thanks in large part to fewer people smoking cigarettes. But from 2019 to 2020， the most recent period available, it dropped by 2.2%，the most ever in a single year, according to a report released Wednesday by the American Cancer Society. That compares with an average 1.5% yearly decline over the decade. The drop translates to roughly 2.9 million fewer cancer deaths than what would have occurred had death rates remained at their peak. For lung cancer specifically, the death rate declined 4.3% annually from 2013 to 2017.
"It is really lung cancer that is driving this," said Rebecca Siegel, scientific director of surveillance research at the American Cancer Society, and lead author on the new study. "We found increases in survival for lung cancer at every stage in diagnosis." She attributed the lower deaths to improvements in treatments, including video-assisted surgery that enables more patients with early lung tumors to become eligible for operations； more precise radiation treatment； and better scanning technology that allows doctors to better assess the stage of tumor, so the patient gets the best treatment right away. At later stages of illness, new, targeted drugs that aim at specific disease-causing genes are helping patients whose tumors have those genetic flaws （缺陷）. Overall, lung cancer death rates have dropped by 51% for men since their peak in 1990， and by 26% for women since their peak in 2002.
There's the potential for more progress in future reports. That's because the latest death-rate statistics go only through 2020， and likely don't include the potential impact in lung cancer death from immune-therapy drugs. They became widely used in lung cancer only in the past few years.
The report, based on U.S. government data, isn't all good news. Prostate（前列腺）cancer death rates have leveled off recently after a period of decline. That may be because many doctors pulled back on using the controversial prostate-specific antigen test, or PSA， which can spot the disease but can lead to over-treatment of men who may never have died from their tumors.
"Though it was definitely causing harm, it was also contributing to declines in death," Siegel said. What's needed now is better screening tests to detect only the prostate cancers that will go on to cause harm.
Population death rates are considered one of the most reliable ways of measuring progress in cancer treatment and prevention. By contrast, cancer survival rates can sometimes be influenced by improvements in diagnosing tiny, early stage tumors that wouldn't necessarily be deadly.
8. According to paragraph 2,
A. cancer death rate reached its peak in 2017
B. death rate decreases over the past 2 decades
C. 2.9 million people die of cancer in America every year
D. most of the cancer patients in America suffer from lung cancer
9. We can learn from the passage that
A. female death rate of lung cancer drops more than that of male
B. targeted drugs have led to rapid increase in cancer death rates
C. better scanning technology will lead to improvement in treating genetic flaws
D. improper use of prostate-specific antigen test can lead to over-treatment of men
10. The underlined expression "level off" in paragraph 5 means
A. remain unchanged B. show up
C. take off D. become sharp
11. What might be the best title of the passage？
A. Medical Progress Prolonging Patients' Lives.
B. Cancer Death Rates Dropping at the Fastest Pace.
C. Significant Improvement in Treating Lung Cancer.
D. Advanced Technologies Applied in Cancer Treatment.

2. C. 推理判断题。根据上句"Don't be blinded by looks, nor sex. Some people who have the gift of looks, or sex appeal, use it to unfair advantage."（有些人拥有长相或性感的天赋，他们利用这天赋获得了不公平的优势。）和后句"To take an extreme example, spies have gotten people to sacrifice a nation's security merely by "bestowing" sex on someone."（ 举个极端的例子，间谍让人们仅仅通过与某人"进行性交易"就可以牺牲国家安全。）可知，C项"事实上，这样的人带来的麻烦可能远远超过他们的价值。"切题，在此起承上启下的作用。C项中的"such people"指的就是上文提及的"那些拥有长相或性感的天赋的人"，同时划线后的例子是对前句进行举例说明。故选C项。
3. A. 段落大意题。分析段落结构可知，此处为本段中心距。根据后文内容"Yes, some people enjoy being nice for its 0wn sake. But other people use kindness as a weapon： to disarm and/or create obligation. So whensomeone" caringly" asks how you are or gives you a ltte gift or two, don't jump to that being aploy, but keep your eyes open."（是的， 有些人喜欢为自己好。但另- -些人把善良当作武器：解除武装和/或创造义务。所以，当有人"殷勤"地问你怎么样，或者给你一两件小礼物时，不要认为这是一种策略，而是要睁大眼睛。）可知，本段主要讲述一些人之所以表现出善良，是因为他们有不可告人的目的。A项"有些人之所以善良，主要是因为他.
4. F. 细节理解题。根据后一句"But other times,your admission will be used against you."（但其他时候， 你承认弱点和过失会对你不利。）可推知，设空处可能陈述有时人们暴露自己的一些缺点会对自己有利。F项"有时候，暴露一个缺点可以打开一段更深层次关系的大门。"切题，与下文构成明显的转折关系。故选F项。
5. E. 推理判断题。根据前句"For example,let's say that you admit that you are insecure about your intelligence."（例如，假设你承认你不相信自己的智商。）和下文"Worse still, there are those who reveal a small weakness or past failing, not to deepen the relationship but to encourage you to admit a more serious failing."（更糟糕的是， 有一些人揭露一个小小的错误或者过去的失败并不是为了加深关系，而是诱使你承认一个更严重的失败）可推知，设空处可能会提到有人会利用你所揭露的自己的弱点或错误。E项"在随后的争吵中，对方可以利用这一点。"切题，和前句构成因果关系。E项中的that指代前句提的" 承认自己缺点"这件事。故选E项。
