Gong Linna, renowned Chinese musician and founder of Chinese New Art Music, put her music teaching methods to practice for the first time at the Tracing Roots practice concert and music festival of the Affiliated High School of Peking University on May 23.
The first song of the concert, Search High and Low, is an allusion (暗指）to the classical poem Li Sao, "The road ahead will be long. I shall search high and low."" It's arranged to be sung by all performers, indicating that we should all search high and low for our roots," Gong says.
To explore the education and the popularization of Chinese music, in 2017, Gong established a research and development team, which includes ethnomusicologist, Du Yaxiong , and music historian, Zhao Zhongming, to deliberate her music teaching methods and summarize the vocal skills of Chinese music.
Gong believed that the popularization of Chinese music should rely on primary and secondary schools rather than music academies . The children's passion for music and their outstanding performance amazed Gong , " When singing, they are completely immersed in the music. Music brings light and richness to one's spiritual world . So, learning to sing is never about passing examinations, but about enjoying the music."
Lu Yueming , instructor of the school's art center, said, "The children worked really hard and kept in mind Gong's instructions. Seeing their performance , I know that they truly fell in love with traditional Chinese music."
"Seeing the children perform my pieces, I realized I should write more songs for
them," Lao Luo, Gong's husband said proudly. " It's a great encouragement for me to see how much they like the songs, and they really need content related to Chinese culture." With an international vision, Gong will continue to write songs based on Chinese folk music or ancient poems.
Gong said children should learn about the beauty of Chinese music. Only when you know about your own sounds, can you have cultural confidence.
24.Why is the song Search High and Low arranged at the concert?
A.Because Gong is a renowned Chinese musician.
B.Because people are expected to search their roots.
C.Because Gong's music teaching method is practical.
D.Because Gong wants to deliberate her music teaching method.
25.What should the popularization of Chinese music depend on according to Gong?
A.Music academies.
B.The support of the government.
C. Primary and secondary schools.
D.Famous musicians across the country.
26.What is Gong's future plan in music?
A.She will train more children to study abroad.
B.She will perform more concerts to promote Chinese music.
C.She will help children learn about the beauty of various types of music.
D.She will write more songs based on Chinese folk music or ancient poems.
27.What's the best title of the passage?

Space Hotel Promises Guests A Truly Out-Of-This-World Vacation
Looking for a true out-of-this-world vacation? Then you are in luck! On Thursday, April5, Texas-based start-up Orion Span announced they were taking reservations for Aurora（极光）Station, the world's first luxury hotel in space, which is expected to launch in 2021and begin welcoming visitors by 2022.
The pill-shaped space station, which begins construction in 2019, will measure 43.5 feet long and 14.l feet wide-about the size of a large private jet's cabin-when completed. It will accommodate four guests in two private suites and two crew members, most likely former astronauts . Hovering about 200 miles above Earth, Aurora Station will circle the planet once every 90 minutes, enabling guests to enjoy 16 spectacular sunrises and sunsets daily, as well as scores of the breathtaking northern and southern auroras that the hotel is named after.
While admiring the beauty of our planet, tourists can eat non-astronaut food
and drinks or entertain themselves with playing cards. Those hoping to do something more worthwhile will be able to engage in astronaut-like experiments such as growing food in a special environment. The Wi-Fi enabled spacecraft will make it easy for guests to share their experiences with friends and family members on Earth. At the end of the week and half-long vacation, returning guests will be treated to a special " hero's welcome", similar to the one experienced by astronauts returning from a real mission.
Before the once-in-a-lifetime trip, guests will have to undergo the three-month-long special training learning how to move in a weightless environment, along with the basics of spaceflight and orbital mechanics. Also, before you start packing your bags, you will have to pay $9.5 million for the 12-day round-trip vacation.
While several companies are planning to build hotels in space, Orion Span hopes to transform sections of used rockets floating in space into hotel rooms, instead of crowding the already messy skies with additional man-made objects.
28.What can be learnt about Aurora Station?
A.People can visit it now.
B.It's construction will last for about 5 years.
C.It can only hold four people in this station.
D.It looks like a pill with the size of a small plane.
29.Why is the station named Aurora Station?
A.Because guests can enjoy spectacular auroras of the Earth.
B.Because the station will give off auroras while travelling .
C.Because the station will run around the auroras of the Earth.
D.Because the hotel is lit up by the auroras of the Earth.
30.What can guests do in a space hotel?
A.Stay there as long as they like.
B. Cook meals like they are at home.
C .Communicate with their family. D. Receive welcome as a real hero.
31.What can be inferred from the last paragraph?
A.There is little room for people to live on the earth.
B.Too many space crafts have aroused people's concern.
C.Space hotels will be necessary in the near future.

The royal family is filled with rules, and one in particular might explain why Princess Charlotte is a princess, but her kids likely won't be.
When it comes to the British royal family, one thing is almost always true: they have a pretty confusing set of official rules and protocols. For instance, the royal family doesn't have a last name. And don't forget the fact that Queen Elizabeth celebrates two birthdays every year.
If your head isn't swimming yet, consider the tradition of royal titles. As a British custom, only the daughter of a prince or a prince's wife may be considered a formal " princess". The latter applies to Kate, who is both a princess and the Duchess of Cambridge thanks to her marriage to Prince William, the Duke of Cambridge . And their children, Prince George and Princess Charlotte, also bear official royal titles because their father is Prince William.
However, while Prince George' s future children will also carry their father's royal status, any children that Princess Charlotte has will not automatically be considered princes or princesses. Why? Royal custom dictates that royal titles are passed down via sons, but not daughters.
"Royal titles are inherited through sons, so if Princess Charlotte has children they would not automatically inherit the titles (his or her royal highness) HRH, Prince, or Princess," Lucy Hume, associate director of etiquette experts Debrett's, told Town& Country.
Of course, exceptions can (and will!) be made. (Learn about every time the British royal family broke their own protocol.) The Queen has offered HRH status to other royal offspring in the past, including the children of Queen Elizabeth's daughter, Anne. Although Princess Anne and her husband , Captain Phillips, declined, perhaps Princess Charlotte will be extended the same offer when her own children are born.
32.What 's the meaning of the underlined word " protocol" in the first paragraph?
A.Promise.
B. Behavior.
C. Manners.
D. Connection .
33.What kind of child is regarded as "princess"?
A.The son of a princess.
B. The daughter of a prince.
C. The daughter of a princess
D. The wife of a king.
34.Who is Charlotte's father?
A.Prince George. B . Elizabeth.
C. Prince William.
D.Captain Philips.
35.What does the last paragraph mainly tell us?
A.Any person can break traditional rules.
B.Not every person must obey traditional rules.
C.Any British royal family member has their own title.
D.Maybe the British royal family will break their own rules.

If you've been feeling a lot sleepy in your daily life, here are some tips to picking up your energy levels. But first, you should make sure if you're experiencing some serious illnesses. 36 , keep these tips in mind.
The first recommendation is to exercise. Although it may seem difficult to
work out when you're tired, it turns out that physical activity can actually give you more energy. The second thing to work on is to go to sleep early enough to get a full night's sleep, preferably so that you wake up naturally without the need for your alarm.
37 . Thus, another useful tip is to take a nap during the afternoon. Naps can restore your mind and body without taking up too much time, regaining your energy and raising working efficiency. The best length of time for a nap is about 20 minutes. Shorter, and you won't get much out of it. 38 .
39 . Drinking plenty of water and fluids throughout the day is one important way to stay energized, since dehydration (脱水）leaves us in low spirits. Some experts say that eating smaller meals more often throughout the day can help maintain energy and balance blood sugar levels. Be aware also that people who are overweight are more likely to experience tiredness easily. 40 , reducing extra weight could help you gain more energy.
A.If you're overweight
B.If you feel uncomfortable
C.As you know, it is quite a good habit
D.However, this goal is hard to achieve in practice
E.longer, and you may find it harder to sleep at night

高三英语周练（1）试题 命题人：考试时间：50分钟总分：89分 Ⅰ. 阅读理解(满分39分) A Food festivals around the world Stilton Cheese Rolling May Day is a traditional day for celebrations, but the 2,000 English villagers of Stilton must be the only people in the world who include cheese rolling in their annual plans. Teams of four, dressed in a variety of strange and funny clothes, roll a complete cheese along a 50-metre course. On the way, they must not kick or throw their cheese, or go into their competitors' lane(赛道). Competition is fierce and the chief prize is a complete Stilton cheese weighing about four kilos (disappointingly, but understandably the cheeses used in the race are wooden ones). All the competitors are served with beer or port wine, the traditional accompaniment for Stilton cheese. Fiery Foods Festival—The Hottest Festival on Earth Every year more than 10,000 people head for the city of Albuquerque, New Mexico. They come from as far away as Australia, the Caribbean and China, but they all share a common addiction—food that is not just spicy(辛辣),but hot enough to make your mouth burn, your head spin and your eyes water. Their destination is the Fiery Food and BBQ Festival which is held over a period of three days every March. You might like to try a chocolate-covered habanero pepper—officially the hottest pepper in the world—or any one of the thousands of products that are on show. But one thing's for sure—if you don't like the feeling of a burning tongue, this festival isn't for you! La Tomatina—The World's Biggest Food Fight On the last Wednesday of every August, the Spanish town of Bunol hosts La Tomatina—the world's largest food fight. A week-long celebration leads up to an exciting tomato battle as the highlight of the week's events. The early morning sees the arrival of large trucks with tomatoes—official fight-starters get things going by casting tomatoes at the crowd. The battle lasts little more than half an hour, in which time around 50,000 kilograms of tomatoes have been thrown at anyone or anything that moves, runs, or fights back. Then everyone heads down to the river to make friends again—and for a much-needed wash! 1. In the Stilton cheese rolling competition, competitors on each team must________. A. wear various formal clothes B. roll a wooden cheese in their own lane C. kick or throw their cheese D. use a real cheese weighing about four kilos 2. Where is the Fiery Food and BBQ Festival held? A. In New Mexico. B. In the Caribbean. C. In Australia. D. In China.
