26、You may have heard of the word “pub” . It is short for public house. There are around 60,000 pubs in the U.K. One of the oldest pubs，Ye Olde Fighting Cocks in St. Albans，Hertfordshire，is located in a building that dates back to the eleventh century.
【1】 People talk，eat，drink，meet their friends and relax there. Pubs often have two bars，one usually quieter than the other，and many have a garden where people can sit in summer. Children can go into pub gardens with their parents.
Groups of friends normally buy “rounds” of drinks.【2】 It is sometimes difficult to get served when pubs are busy：The bar staff will usually serve those who have been waiting the longest at the bar first.
Most pubs offer a complete range of beers，local and imported，with German，Belgian and French beers being in demand.【3】 As a matter of fact，pubs sell soft drinks，too.
The legal age to purchase alcohol is 18 in the UK. People aged 16 and 17，with the license's permission，may have only one glass of wine during a meal.【4】 It is illegal to sell alcohol to someone who already appears drunk. A fourteen-year-old may enter a pub unaccompanied by an adult if he orders a meal. Children may enter a pub with their parents until 9 p．m.，which lets families enjoy reasonably priced pub meals together. 【5】Customs in British pubs differ from those in American bars. In most pubs in the U.K.，you must go to the bar to order drinks and food and pay for your purchases immediately.
A．British people like drinking beers in pubs.
B．Pubs are an important part of British life.
C．But they must be with an adult and the adult orders it.
D．In the salon bar the atmosphere is quieter and there are fewer people.
E．And it also allows pubs to play their traditional roles as community centers.
F．The person whose turn it is will buy drinks for all the members of the group.
G．Most people might think pubs are places where people simply drink alcohol.
27、 In 1977, a University of Oxford statistician named Richard Peto pointed out a simple yet puzzling biological fact: we humans should have a lot more cancer than mice, but we don’t.
Dr. Peto’s argument was simple. Every time a cell divides, there’s a small chance it will gain a mutation(突变) that speeds up its growth. Cells that accumulate (聚集) several of these mutations may become cancerous. The bigger an animal is, the more cells it has, and the longer an animal lives, the more times its cells divide. We humans undergo (经历) about 10,000 times as many cell divisions as mice—and thus should be far more likely to get cancer.
A number of scientists have assumed that large, long-lived animals must have evolved extra cancer-fighting weapons. Otherwise, these species would die out.
Dr. Joshua D. Schiffman, an oncologist (肿瘤学家）at the Huntsman Cancer Institute, reviewed zoo records on the deaths of 644 elephants and found that less than 5 percent died of cancer. By contrast, 11 percent to 25 percent of humans die of cancer.
To understand the elephants’ defenses, the scientists investigated a gene that is vital to preventing cancer called p53. The protein encoded by the gene monitors cells for damage to the DNA they contain. Dr. Schiffman and his colleagues found that elephants have evolved new copies of the p53 gene. While humans have only one pair of p53 genes, the scientists identified 20 pairs in elephants.
To see whether these extra copies of p53 made a difference in fighting cancer, they ran experiments on elephant cells. They treated elephant cells with damaging radiation, chemicals and UV light.
“In all cases, instead of trying to repair the damage, the elephant cells simply committed suicide” said Dr. Schiffman. He said he thought the way the elephant cells responded was a very effective way to block cancer.
Patricia Muller, an oncologist at the MRC Toxicology Unit at the University of Leicester, who was not involved in the studies, said the results, though convincing, didn’t firmly establish exactly how elephants use p53 to fight cancer. One possibility is that the extra copies don’t actually cause cells to commit suicide. Instead, they may act as decoys (诱饵) for enzymes (酶) that destroy p53 proteins.
Dr. Muller said it was especially important to understand precisely how elephants fight cancer before trying to copy their strategies with drugs for humans.
【1】What does the 2nd paragraph want to tell us?
A.Human should be more likely to develop cancer than mice.
B.Cell division can increase the speed of growth of mutations.
C.The bigger an animal is, the smaller chance of getting cancer it has.
D.Dr. Peto’s argument was not simple.
【2】According to the passage, p53 is ______.
A.a protein to prevent cancer B.a gene to defend against cancer
C.a protein to destroy damaged cells D.a gene to change cells
【3】What does Dr. Schiffman say about the extra copies of p53 fighting cancer?
A.They cause the cells to repair the genes.
B.They stop cells from dividing further.
C.They act as decoys for enzymes that destroy p53 proteins.
D.They cause the cells to commit suicide.
【4】Which of the following is TRUE?
A.Dr. Schiffman pointed out that we humans don’t have more cancer than mice.
B.The cancer death rate of humans is five percent higher than that of elephants.
C.The scientists found there are 20 pairs of p53 genes in elephants.
D.Dr. Muller also took part in the studies.
28、 Kendrick Lamar hasn't had much luck when it comes to winning a Grammy (格莱美奖). But that's OK. The US rapper (说唱歌手) has just won a Pulitzer Prize for his music.
In 2017, in 2019, and again this year. Lamar was nominated (提名) for an album of the year Grammy. Each time, he was beaten out, first by Taylor Swift, next by Daft Punk, and most recently by Bruno Mars.
But the Pulitzer Prize committee was inspired enough by Lamar's 2020 album, Damn，to award the 30-year-old its Pulitzer Prize in music on April 16. It's an amazing album that documents the real life of modern African-Americans in South Los Angeles with wildly accomplished beats and rhythms.
Lamar's win is considered to be historical. The Pulitzers have long displayed their preference toward high art rather than the pop culture of the masses. So it's not just that no rapper has ever won a Pulitzer: no pop music maker has ever won one in the award's 75-year history.
But Lamar is not just a singer—he's clever at using language. Like the best writers, his music describes small moments that illustrate (阐明) larger points. His songs are about his experience as a black man who grew up in California, struggled, got into trouble, and found his way out by working hard and making sense of the history and reality of racial problems in the US.
"He's an artist who challenges idea," said Ryan Coogler, director of the blockbuster (大片) hit Black Panther, for which Lamar created music. "One big theme in our film is the idea of, 'What does it mean to be African?' Kendrick in his music is very exactly and directly challenging that question."
Good artists entertain us, great artists make us think, and exceptional artists help us empathize (感同身受).
There are a lot of good, great, even exceptional artists in rock, pop, country, and hip-hop. But only Lamar has a Pulitzer Prize.
【1】What is Lamar's album Damn about?
A．African-Americans，history and culture.
B．Hardships of the African-American artists.
C．The ways the US government deal with racial problems.
D．The lives of modem black people in South Los Angeles.
【2】How many times was Lamar nominated for an album of Grammy?
A．0ne.
B．Two.
C．Three.
D．Four.
【3】Why is Lamar's Pulitzer Prize win significant?
A．He is the first film-maker to win the prize.
B．It is considered a milestone for pop music.
C．He is the first black person to win the prize.
D．He has missed Grammy several times before.
【4】What can we learn from Ryan Coogler's words?
A．Lamar drew inspiration from his own experience.
B．Lamar has the courage to take on big challenges in life.
C．Black Panther is well known because of Lamar's music.
D．Lamar's music matches the theme of Black Panther well.
29、
Elephant Reserve Country: Thailand This is a working vacation at a wildlife centre. Anyone can become a volunteer if he/she agrees to help the elephant keepers with tasks. Daily tasks Gather the elephants at 6:30 am. Take them to look for food in the forest. Clean the enclosure(围场). Swim with the elephants in the lake in the afternoon. If volunteers want to relax after work, they can watch satellite television. How this vacation helps If these elephants hadn’t been rescued, they would still be living on the streets of Bangkok. The rural environment is much better for them than the urban environment where there is lots of pollution. Your Comment “I love working with these huge gentle animals.” |
Gorilla safari(观赏野兽的旅行) Countries: Kenya, Rwanda and Uganda Departures(出发): 2—3 departures per month from Aug. to Dec. Extras: permit ￡220 If you’re lucky, you’ll see lions, elephants and rhinos during this safari. The highlight(最好的部分) of the trip is the opportunity to see gorillas in the mountain forests. However, you must be in good health — if a gorilla caught a cold, it would be extremely harmful to its whole family. How this vacation helps There are only about 600 gorillas left in the world as human activity has reduced the area where they can live. When you buy a permit, this will pay for the protection of the national park. Your comment “I’ll surely go back as soon as I have enough money!” |
Polar bear watching Area & Country: Arctic, Canada Departures: sixty trips between Oct. 1—Nov.19. Every October and November groups of polar bears gather in Hudson Bay. As they are normally lonely creatures, this is unusual. The bears wait for the ocean to freeze so that they can hunt for seals, so this is the perfect opportunity to see them. Extra activities include dog sledding(狗拉雪橇) and a night trip to see the Northern Lights. How this vacation helps If the Arctic ice cap melts due to global warming, polar bears will be in danger. We give a share of our profits(利益) to the charity that protects polar bears. Your comment “These terrible bears get all the liquid they need from their food.” |

Cycling isn’t always easy. Busy streets, honking horns(喇叭), and not enough bike lanes can make it an uphill battle. But not even these difficulties can stopEuropeans’ love for cycling. According to BBC, bicycles outsold cars in 26 of the European Union's 28 states last year.
There are traditional "bicycle capitals", such as Amsterdam in the Netherlands and Copenhagen in Denmark. But in many other traditionally car-made countries,the shift( 转变)to bikes is amazing. Italians, for instance, bought
1.6 million bikes against 1.4 million cars in 2012.
So what has led to cycling,s growing popularity in Europe?
The economic crisis(危机) has played an important role in the issue.”The economic crisis has had an influence on all areas of people's lives, including on transport” Giulietta Pagliaccio, head of the Italian cycling federation Fiab, told the Australian Associated Press.
Since the European debt crisis broke out in 2009, more people lost their job while the cost of living, including fuel costs, continued to rise. It forced many people to give up driving to save money, the Guangzhou-based New Express(《新快报》commented. Take Greece, a country seriously hit by the crisis, for example. It sold320,000 bikes last year against 58,000 cars.
More importantly, people have changed their views toward cars and bikes. Cars are losing their attraction as status( 地 位 ) symbols. Yet, cycling is now seen as"a safe clean, healthy, inexpensive way to get around town, "the Daily Star concluded. "It not only reduces traffic jams and pollution, but also contributes to public health."
However, with more and more people tuning to cycling, questions come up about traffic and safety problems.
To ease people's worries, quite a few cities now offer well-marked bike lanes such as the cycling super-highway marked in blue in London. Copenhagen, for example, it has spent 22 million euros (183 million yuan)in cycling, widening roads and building more parking places.
