1 . It’s easy to assume that a vacation to Bali will cost a small fortune. There are plenty of accommodations, food and local transportation, and even the spas offer massages and treatments at value prices. However, you can easily spend a week or two in Bali for under $2,000, without having to sleep on the beach. Here are a few things to consider when planning Bali on a budget.
What is the best time to visit Bali on a budget?
If you’re on a budget, consider visiting Bali during the lower, wetter season, which runs from October through March. The crowds will be fewer, and both hotel rates and flights from abroad are often cheaper, except during the holiday period between mid-December and early January, when crowds swell. The only trade-off for the lower prices is the wet season. This time of year isn’t always ideal for sunbathing, and serious rainfall can make outdoor activities, such as whitewater rafting and visiting waterfalls and rice terraces, less than appealing. That said, even during rainy season, it doesn’t usually rain all day long. Expect bursts of sunshine between the storms.
What is the cheapest way to get around Bali?
The absolute cheapest way to get around Bali is by local bus, but it can take a long time. There are also tourist buses, including hop-on, hop-off options, that travel between different hubs across the island. Bali is well-served by taxis, both of the car and motorbike variety, and the prices tend to be affordable by international standards. Most drivers will offer you a fixed rate for full-day hires or to get from point A to point B, rather than using a meter.
Remember to bargain; doing so is particularly easy when a driver is on his own rather than at a taxi stand.
How much does food cost in Bali?
If you’re into fine dining, you can end up spending a large chunk of your budget on food. Eating at the average restaurant geared towards tourists is the best way to have a meal in Bali on a budget. A good meal should cost you around 100,000 rupiah (around $7), but if you’re willing to subsist mostly off of local specialties such as nasi goreng (fried rice) and eat at local restaurants, you can expect to pay around 30,000 rupiah ($2) to get fed. Best of all, most hotels and guesthouses in Bali come with free breakfast, and many offer heavier options of noodles and meat that may keep you full until lunch.
1. Which of the following situation can be best described by the underlined word trade-off in paragraph 2?| A．Jack got a reward after he returned the lost bag to its owner. |
| B．Lily spent much money buying some handicrafts at the local fair. |
| C．Wendy cancelled her trip in order to prevent the spread of the virus. |
| D．Sam was scolded by his parents for what he did in school last night. |
| A．It’s better for outdoor enthusiasts to visit Bali during the off season. |
| B．Passengers had better fix the price with drivers before the taxi pulls out from the station. |
| C．If on a tight budget, one is advised to visit Bali at the end of December every year. |
| D．It’s relatively economical to eat merely at average restaurants tailored to visitors. |
| A．City and Transport. | B．Travel and Recreation. |

2 . Those days of sucking (吮吸) up the sides of your rapidly melting (融化) ice cream may soon be over. Researchers have discovered a natural protein that could be added to everyone’s favorite summertime snack to keep it solid for longer, according to a press release from the University of Edinburg in Scotland.
Most people know that, at its most basic, ice cream is made of milk and sugar. But it has other ingredients that give it a solid consistency (黏稠度) — a fat (often oil), air bubbles, and ice crystals. The protein that the researchers discovered, called BsIA, coats all three of them to slow down the rate at which the ice melts and the air escapes. In one study of the protein, published earlier this year, the researchers call BsIA a “raincoat” that can act as a film to keep everything inside it for just a little longer. That same quality prevents big pieces of ice crystals from forming, which can happen if you leave ice cream in the fridge for too long.
BsIA is found in bacteria called Bacillus subtilis that is common in soil, and is already present in some foods. So adding the protein to ice cream wouldn’t bring the same sorts of long-term health concerns as would artificial ingredients (人造添加剂). The researchers note that producers could also add BsIA to ice cream to reduce their fat and sugar content.
Though the researchers have published two papers about BsIA and have tested it in the lab, they are staying quiet on the most recent data they collected, as the Washington Post notes. Importantly, the researchers make no mention about how the new ingredient might affect ice cream’s taste or how much we might enjoy eating it. What’s the good of long-lasting ice cream if you don’t even like it? But it might not be too long before you can try it out for yourself; ice cream with BsIA might be available within three to five years.

3 . As a boy, I wanted to go to the South Pole. As a teenager, I decided I'd like to go to the North Pole too. And yet, I haven't done either. It had taken me 31 years to just make it to the Arctic.
I was traveling with a film crew from Northern Ireland, following the footsteps of Lord Dufferin who, in the 1850s, sailed from Scotland to the Arctic. As an early adventure tourist, he was driven by the desire to see what lay at the ends of the world.
As we sailed north, icebergs of the size of buses floated past our small boat. Finally, we reached our destination—English Bay, where Dufferin landed- and stepped off onto the horseshoe-shaped beach.
This was what I'd dreamt of: standing somewhere so pure and primitive. However, for many early polar explorers, the results were far less pleasant. The south, in particular, was source of extreme danger.
My childhood interest in the South Pole was fueled by the unsuccessful yet heroic adventures of Emest Shackleton. He died in 1922 while preparing for his fourth adventure. The stories of Robert Falcon Scott are also well-known: he and four companions died on their way back from the South Pole.
So why do explorers put themselves at such risk?
Much of it seems to lie in the purity of the challenge. Scott talked of the appeal of a place that had been “unreached and unseen by humans.” “With a view over shining lands covered by ice-sheets of inconceivable extent, you have the feeling of living over the control of death,” said Fridtjof Nansen, a Norwegian explorer.
On the homeward journey the weather turned and we were left for a few days at the mercy of a storm. We experienced a small taste of helplessness when faced with the raw power of nature. We should be grateful for the great explorers’ spirit and stories. I know I am.

| C．Hard to imagine | D．Too bright to view |
| A．They were trapped in icebergs | B．They were kept off the destination |
| C．They were attacked by a storm | D．They were rescued by explorers |

4 . Improve Cloud Security
Sensitive customer data has constantly been found exposed on cloud servers without password protection. To ease the problem, database software makers have been trying to make security easier for cloud database managers. At the Enigma Conference in San Francisco, Kenn White, a security manager at database software maker MongoDB, will describe a new technique, called field level encryption, to make data safer on the cloud.
Field level encryption works by scrambling data before it’s sent to a cloud database and rearranging it in order when the data is needed for use. The promise of the product is to protect the contents of a cloud database, even if bad guys access it.
MongoDB’s new feature comes as more and more companies move user data to cloud servers, rather than run their own costly data centers. It was predicted that cloud computing would be a $214 billion industry by the end of 2019. That would be up more than 17% from 2018, when it was $182 billion.
Companies have rushed to the cloud without understanding all of the possible security consequences. Many companies have left countless databases exposed, revealing personal data. A database containing details about who lives in 80 million US households was left unprotected in 2019, just like the data on Facebook users.
Database managers want to store their data in an unreadable form, but they also want to be able to find specific pieces of information in the database with a simple search term. For example, someone might want to look up health care patients by their Social Security numbers, even if those numbers are stored as random characters. To make this possible, field level encryption lets database managers encrypt a search term on their machine and send it to the database as a query. The database matches the encrypted version of the search term with the record it’s storing and then sends it back to you.
This approach only works with specific kinds of data. For example, field level encryption isn’t useful for long text entries, like notes in a patient’s medical chart, because you can’t search for individual words.
Still, for data like account numbers, passwords and government ID numbers, field level encryption protects data and maintains a usable database.
Most importantly, White said, it’s simple to set up. Database managers turn it on with a one-time configuration change when they set up the database. “That’s really powerful,” he said in an interview.

5 . An international group of electronic music composers is taking beats from the dance club to jungles and forests and back, all to help save nature's greatest singers. A Guide to the Birdsong of Mexico, Central America and the Caribbean is a new album that includes the sounds of endangered birds. The album will come out next month, whose proceeds will go directly towards efforts to save birds.
The whole project was born out of this idea of trying to combine birdsong, electronic music and conservation. A Guide to the Birdsong of Mexico, Central America and the Caribbean was organized by activist, music producer, Robin Perkins. He invited artists from each of the endangered birds 'homelands to build their own songs around the birds’ songs. There are contributions from ten artists in eight different countries.
First single Black Catbird was created by The Garifuna Collective, from Belize. Al Obando, guitarist and producer of the group, always took in national parks and viewed birds when on the road with the band. “There are no trails, and there are no signs there to tell you about what you reseeing,” Obando says. “So we're trying to do something for the birds and nature tourism.”
Another musician who responded to Robin's call is Tamara Montenegro, an artist from Nicaragua. She was shocked to hear of the serious situation of the Guardabarranco after being approached: “This beautiful creature I grew up adoring also faced the influence of the systematic human activities”. In response, she created a song inspired by this bird and the challenges it faces to live naturally.
The new album is the second edition, following on from A Guide to the Birdsong of South America, produced by Robin in 2015. That first album has raised, to date, over $15,000 benefitting conservation projects in South America. As with the first album, all of the money from the sales of the new album will support specific organizations, including Birds Caribbean.

6 . It's a typical morning: you wake up, take a shower, brush your teeth, and then prick(刺)your arm with a tiny needle. Wait, what? Unless you have a serious disease such as diabetes,you probably haven't ever tested your own blood. But in the future, that might change.
The company Cor already sells a system for home blood testing. You stick your arm using a supposedly painless cartridge. Then you stick the cartridge into a device that looks like the base for an electric toothbrush. A few minutes later, an app on your phone offers you updated information, including your current health status and tips on what to eat and how to exercise.It's true that blood provides abundant information about a person's health. Specific tests can reveal if a person is infected with a disease or at risk for a variety of problems. But most people don't test their own blood often. Healthy young adults get blood tests approximately every five years. Cor and similar companies are trying to change the situation. They think people deserve access to more information about their health.
But not everyone is convinced."The best-case scenario(情景)here is that you lose much money and then you're reminded to get more sleep and to eat more fruits, vegetables and fish,"Pieter Cohen of Harvard Medical School told The New York Times. Plus, the results of a home blood test might be wrong. It's hard to get accurate results from a tiny amount of blood. One company, Theranos, said it could perform medical blood tests on a fingerprick's worth of blood.But the company was soon stuck in a controversy((争议)and accused of cheating because its technology didn't work as promised. Thus, there's still a long way to go before the technology becomes advanced.

7 . The joy of giving is real, according to a study. Research presented in the Journal of the Association for Psychological Science shows that those who give gifts are happier — and happier for longer — than those who receive gifts.
Researchers conducted two studies last year. In one，participants were given $5 every day for five days and were required to spend the money on the same thing each day. Some participants were required to spend the money on themselves, while others were required to give to make a donation to charity. In a second experiment that was done online, participants played 10 rounds of a word puzzle game and each won 5 cents per round, which they could keep or donate.
In both experiments, participants reported their overall happiness. Those who donated their money showed that their happiness declined at a much slower rate than those who kept the money or spent it on themselves.
The researchers note that when people focus on an outcome, they can easily compare outcomes, which may diminish their sensitivity to each experience. When people focus on an action, they may focus less on comparison and instead experience each act of giving as a unique happiness-inducing event. Further analyses ruled out some potential alternative explanations, such as the possibility that participants who gave to others had to think longer and harder about what to give, which could promote higher happiness.
The results are especially interesting because according to one of the researchers, Ed O’Brien of the University of Chicago Booth School of Business, they conflict with past research. “If you want to sustain happiness over time, past research tells us that we need to take a break from what were currently consuming and experience something new. Our research reveals that the kind of thing may matter more than assumed: Repeated giving, even in identical ways to identical other，may continue to feel relatively fresh and relatively pleasurable the more we do it,” O’Brien said.
So for all the holiday gifts you give this season, expect to feel happy and know that feeling is going to stick around for a while.

8 . While it's not impossible for birds to fly in the rain, they usually choose not to. You may see birds fly for a few seconds in poor weather, but most of them prefer to stay put on rainy days.
Why does rain make it harder for birds to fly? You might imagine that moving through the air while being pelted by raindrops would be pretty unpleasant. However, it's not the rain itself that makes flying difficult. Instead, birds are influenced by the drop in the air pressure that comes with most rainstorms. When pressure drops, the air is less thick, which makes it harder for birds to fly. Moving through the sky in areas of low air pressure takes a lot of energy.
Most birds need to eat several times a day—rain or no rain. Luckily, most birds' feathers（羽毛）are highly waterproof（防水的）, protecting the skin beneath. Many birds can also make oil that they can spread over their feathers to further protect themselves from the rain. Most birds don't like rain. In fact, in a 2010 study, a team of researchers studied birds living in a Costa Rican rainforest. They found that the birds had higher levels of stress hormone（应激激素）on rainy days. That may not surprise you. After all, many animals feel stressed out during storms. Pet owners often find that rain and thunder make their animals nervous. Some animals are so strongly influenced by nature that they almost seem to forecast the future.
No one really knows how many birds die during a storm or series of storms. But the number is certainly higher than usual. They fly into trees or windows; they get lost over the ocean or a large lake; their food sources are made more difficult to get but, at the same time, they need more food to get warm. However, if rain continues for some time, birds will have to challenge the storm.

9 . Facebook is a habit forming activity， but users who spend a lot of time on the site say they feel less happy with their lives.
Researchers from University of Gothenburg say that many users log in as soon as they turn their PCs on and that the behavior can develop into an“addiction”. People in low income groups and the poorly educated are particularly at risk. Up to 85% of users say that they use Facebook daily and half say they start up Facebook as soon as they open their web users. Half fear that they are not“on top of things”if they are not logged into the site, and 25% say they feel”ill at ease”if they can't log in regularly.
The Swedish survey showed the network had its dark side.“Face-booking may become an unconscious habit. A majority of the respondents(受访者) log in every time they start their web browser(浏览器). This may even develop into an addiction,” says Leif Denti, doctoral student of Psychology at the University of Gothenburg.
People with low income and low-educated individuals spend more time on Facebook. Women are generally more active than men on Facebook. Users with low income and low education use Facebook more than other groups. Within these groups，users who spend more time on Facebook also report feeling less happy and less content with their lives.
The other surprise about the network is that although a huge amount of personal “ news”is traded through the site,it tends to focus on the positive.“ Most of the content they share has something to do with major events, positive events and when feeling good,”says Leif Denti.

10 . There you are, looking through your WeChat moments or your Weibo feed, and you come across a post saying something like this: “I just got accepted to Harvard and 0xford! Are they sure they didn’t mix my applications up with somebody else’s?”
This person is clearly humblebragging. The term “humblebrag” was first coined back in 2010 by the late US comedian Harris Wittels, and it describes when someone makes a seemingly modest statement, but the actual purpose is to bring attention to something they are proud of.
The example above is a modesty-based humblebrag. The person wants to tell others: “I got accepted to Harvard and Oxford!” However, they don't want to seem too proud of their accomplishments. So, instead, they word it in a way to be more modest and bring down the importance of their achievements.
Although people who humblebrag think it will make them more likeable because they aren’t talking proudly about their victories, a study published in the Journal of Personality and Social Psychology showed that humblebragging actually has the opposite effect.
“Humblebragging doesn’t have the intended result because it seems insincere. That ‘poor me’ attitude combined with self-promotion does not lead to a favorable impression,” said Ovul Sezer, the lead author of the study and an assistant professor of organizational behavior at the University of North Carolina, US. “ Even simply bragging or complaining (抱怨) is better, because at least those messages are seen as more sincere.”
Sezer’s study also found that nearly 60% of humblebrags were complaint-based humblebragging, with most people humblebragging about their looks, followed by their money or wealth, and finally about their performance at work. “It’s such a common phenomenon. All of us know some people in our lives, whether in the social media or in the workplace, who do this annoying thing,” commented Sezer, adding that we all do it to some extent.
So, if you want to share your achievements with others, what’s the best way to do it then? Sezer suggests that people admit their self-promotion and harvest the rewards of being sincere. She also suggests finding a go-between, adding, “If someone brags for you, that’s the best thing that can happen to you, because then you don’t seem like you’re bragging.”
