Albert Einstein, the genius behind the theory of relativity, has recently been making headlines again. However, this time it is not for a new scientific breakthrough,1. for a handwritten note he gave a bellboy 95 years ago.
In October 1922, Einstein was delivering a series of lectures in Japan 2. he received a telegram informing him that he 3. (award) the Nobel Prize for Physics. Though 4. (please) at the news, the Nobel winner decided to continue with his Japanese trip instead of 5. (head) to Stockholm to accept the honor.
While in Tokyo, he penned 6. note in German,saying “A quiet and humble life will bring more 7. (happy) than the pursuit of success...” Perhaps he had no loose change to tip a bellboy coming to deliver the message, he gave him the note, and told him,“Maybe if you are lucky, the note 8. (become) more valuable than just a regular tip. ”
Earlier this year, the bellboy’s nephew decided to hand it to Jerusalem-based Winner’s Auctions (拍卖) and Exhibitions. The note was then put up for auction,9. might bring the owner a surprising $1.56 million 10. a European buyer. It was a record for an auction of a document in Israel and the wild-haired scientist deserved it.

Nowadays people tend to digitalise everything from watches to fridges. It seems you can choose any item labeled as “smart”. 1. However, there are plenty that can be used to reduce emissions and save money.
If you’re a part of the digitalisation movement，you might be interested in the concept of smart homes. It means that every element of your house can be controlled from a panel on the wall or your phone.2. Use your mobile to power them on or off，and you may feel truly modern or truly lazy. Asides from the benefits of living a more comfortable life, this presents an opportunity to cut down on your electrical bills.
Electricity generation today represents 31% of total global fossil fuel use and around 40% of all energy-related CO2 emissions.3. It is considered as the first step to prevent global climate change. Connect a smart thermometer to the heating and cooling system and set a specific temperature at which the heating begins to work. Doing so, the room will be at a desired temperature when necessary and switches on a power-saving mode when not occupied. Similarly, by installing a CO2 sensor, you can have an automated ventilation (通风) system.4..
In a 150,000m2 office complex near Munich， called Campeon, energy costs of up to 117,067 Euro were saved after the use of environmental control devices this year. In this way, they are contributing to a large decrease in CO2 emissions. Clearly, smart homes are about much more than just living a comfortable life.5..
A. It is actually about living a green life.
B. Smart devices have been installed worldwide nowadays.
C. It starts working only when CO2 concentrations reach a certain limit.
D. There seem to be an ocean of such so-called “smart” inventions.
E. Bearing this in mind, measures should be taken to make buildings more energy-efficient.
F. Alternative energy must be discovered before the fossil fuel runs out in the future.
G. This includes basics such as heating and lighting and many other appliances.
More than 40 percent of the species that help with pollination (植物传粉) are under threat due to the polluted environment. So some researchers have been searching for ways to protect the bees and other crucial pollinators while some engineers have thought perhaps an army of robotic pollinators could keep humans well-supplied in these foods. A team of researchers has recently designed a small drone capable of pollinating flowers. They tested their device on the large, pink flowers of lilies. And it worked.
Exciting as this success was, it is only the first step. The team has yet to figure out how to apply the concept on the massive scale. Could a fleet of robo-pollinators replace the bees?
“Although the answer isn’t a straightforward no, it would be a challenging leap to go from this one little drone pollinating one large flower to an army of drones spreading across fields of crops,” says Scott Swinton, an agricultural economist at Michigan State University.
“The successful pollination was fascinating,” Scott Swinton says, “but the device itself might damage the flowers. I wonder how you make sure you’re not doing more harm than good to flowers when you have a drone.”
“Furthermore,” he points out, “a lily is a particularly easy flower for a drone to pollinate. To make this more broadly applicable for smaller and more complex flower structures, the drones would need to be particularly agile.”
Still, Joshua Campbell, an expert at the University of Florida, says “Pollination systems are extremely complex and will always require insects. There is no substitute for bees.”
“As for the technology itself, it is a promising new development in existing drone technology,” he added. Yet he still sees some hurdles ahead before drones can be applied on a large scale.
1.What makes those scientists invent pollinating drones?
A. There are no satisfying pollinators.
B. Humans need more food supplies.
C. Pollinating species are being endangered.
D. Drone technology is well-developed now.
2.What problem does Scott think scientists have to solve for the robo-pollinators?
A. Making them look like bees. B. Using them in quantity.
C. Keeping them flying non-stop. D. Instructing them to tell plants.
3.The underlined word “agile” in Para 6 can be replaced by “________”.
A. cheap B. catchy
C. lovely D. smart
4.What’s the best title for the passage?
A. Will pollinating drones take over for honeybees?
B. What is leading pollinating honeybees to decline?
C. Why does pollinating need a money-saving option?

The world is a greener place than it was 20 years ago. A study published in the journal “Nature Sustainability” said that recent satellite data reveals a greening pattern that is strikingly prominent in China and India. The study shows that human activity in China and India dominates this greening of the planet, thanks to tree planting and agriculture. The effect comes mostly from ambitious tree-planting programs in China and intensive agriculture in both countries.
“China and India account for one-third of the greening, ” said lead author Chi Chen of Boston University. “ That is a surprising finding, considering the vague idea of land degradation (毁坏) in populous countries from overexploitation, ” added Chen.
China alone accounts for 25 percent of the global net increase in leaf area with only 6.6 percent of global vegetated area. The greening in China is from forests (42 percent) and croplands (32 percent), but in India, it is mostly from croplands (82 percent) with minor contribution from forests (4.4 percent).
China’s outsized contribution to the global greening trend comes in large part from its programs to conserve and expand forests with the goal of preventing land degradation, air pollution, and climate change.
“Once people realize there is a problem, they tend to fix it,” said Rama Nemani, research scientist and co-author of the study. “In the 1970s and 80s in India and China, the situation around vegetation loss was not good. In the 1990s, people realized it, and today things have improved. Now we see that humans are contributing.”
Land area used to grow crops is comparable in China and India—more than 770, 000 square miles—and has not changed much since the early 2000s. Yet these regions have greatly increased both their annual total green leaf area and their food production.
This was achieved through multiple cropping practices, where a field is replanted to produce another harvest several times a year. Production of grains, vegetables, fruits and more have increased by about 35%～40% since 2000 to feed their large populations.
1.What did the study mainly find?
A. India and China are leading the global greening effort.
B. Intensive agriculture is the cause of global land degradation.
C. China and India has got the largest forest coverage in the world.
D. Agriculture is more helpful in expanding green areas than tree-planting.
2.How is China different from India in contributing to the global greening?
A. India reduced cropland to prevent the overexploitation.
B. India increased forest by planting around croplands.
C. China changed more lands into forest by planting trees.
D. China controlled the increase of its population.
3.What does Nemani think about humans in China and India in protecting the Earth?
A. Ambitious. B. Responsible.
C. Passionate . D. Tolerant.
4.What does the passage finally suggest humans should make good use of?
A. Forest. B. Trees.
C. Cropland. D. Food
Across Europe, where visitors can outnumber residents in the summer months, the complaints have started. Last week, in Barcelona, an open-top bus was spray-painted across its windscreen with the words “Tourism Kills Neighbourhoods”. The message is clear: such cities are under pressure. In tourists and residents’ battle for shared spaces, local authorities are uncomfortably in the middle. The tourism is one of the largest employers in the world, with one new job created for every 30 new visitors to a destination—but at what cost to locals’ quality of life?
More people are travelling than ever before, and lower barriers to entry and falling costs mean they are doing so for shorter periods. The rise of “city breaks”—48-hour bursts of foreign cultures—has increased tourist numbers. “Too many people do the same thing at the exact same time,” says Xavier Font, a professor at the University of Surrey, “For locals, the city no longer belongs to them.”
Compounding the problem is Airbnb, which has made tourists more casual in their approach to international travel, but added to residents’ headaches. Those permanent citizens who share their apartment blocks with Airbnb hosts have lost their patience, “No longer do we have to share the streets with tourists, we have to share our own buildings!” To ease the congestion around the main attractions, many cities are taking immediate action. Venice is proposing a new concept of “ detourism”: sustainable travel tips and alternative routes for exploring a different Venice. A greater variety of guidance for future visitors—ideas for what to do in off-peak seasons, for example, —can guide them from overcrowded landmarks. Repeat visitors have a better sense of the culture and it is much easier to integrate their behaviour with residents of the cities.
“But the locals should learn to take tourists as a part of urban life. Tourists do not have to be considered passive players, but rather as visitors with rights and duties,” says Font, “Everyone has a part to play in promoting that change.”
1.What problem do the local authorities often have in a tourist city?
A. The challenge creating more business for local people.
B. The conflict taking place among tourists from different countries.
C. The dilemma between tourism and living quality of the locals.
D. The competitions among the most popular attractions.
2.Why do the local residents reject “city break” according to Paragraph Two?
A. Too many visitors have damaged the quality of life.
B. The locals fail to benefit from the city break economically.
C. The local authorities lack adequate operation guidance.
D. They are reluctant to share anything with coming tourists.
3.What is Airbnb most probably?
A. A new travelling map with more street information.
B. A solution by Font to improve the local living quality.
C. A small town having the same complaints about tourism.
D. A website to help travellers find a homestay.
4.Under the concept of Detourism, which of the following should be encouraged?
A. Developing a city break during on-seasons.
B. Shifting visitors from busy attractions.
C. Attracting more first-time visitors.
D. Taking tourism as a passive part of urban life.
