The best of Bali in 48 hours
Bali(巴厘岛) is home to most of Indonesia's Hindu minority. Here's how to get the most out of a 48hour visit：
FRIDAY
3pm—There's nothing like a good meal. La Lucciola is the place to go, with its good food, great service and a beautiful view of the sea.
You can hire a car for some 450,000 rupiah per day. This will help you have more to spare during your trip there.
5pm—About an hour away from La Lucciola is Uluwatu. This southern tip of the island is famous for its temple that lies on the edge, high above the sea. Fire dance is performed here daily at sunset.
8pm—To finish off the evening, head to Jimbaran Bay where restaurants offer candles, dances, boys singing songs. Kick off your shoes, feel the sand, and enjoy the night.
SATURDAY
9：30am—Start the day with another taste of culture by heading for a “barong and keris” dance performance. It's held in many places. One is the Catur Eka Budi in Denpasar, capital of Bali.
12pm—About 50km from Denpasar is Kintamani, a favorite with tourists for the view of active volcano Mt. Batur. It's a good idea to reach Kintamani early as it gets cloudy after 3pm. Have lunch at a local restaurant with a view of Mt. Batur. Tourists can climb to Mt. Batur to catch the sunrise.

We chat with our colleagues all the time when we have lunch, gossip in the tearoom, or leave work together. Sharing your personal life brings you closer to your coworkers and builds trust within your team. But revealing too much about yourself to colleagues, managers or human resources staff can cause difficulties and even endanger your work.
It's important to keep the right balance between getting along with colleagues and maintaining your privacy. “Communication in the office is tricky and complicated. You can neither spread chatter, nor be too silent and shut yourself off from others，” said Yang Yudan, deputy HR director at P&G.
According to her, there are several safe topics to talk about with colleagues during the break, such as the weather or movies. Women like to talk about makeup and clothing, while men are fond of sports and online games. But discussing your private life, such as relationship, habits or health conditions, is a potential minefield.
Liang Kun, 26, had to resign from his job at a trading company in Guangzhou last week after discussing his income with colleagues during a lunch break. “I didn't realize it was such a serious issue until a senior member of staff went to find the boss, asking why I got a higher salary than her，” said Liang. “Then our HR told me that according to the employee handbook it is forbidden to talk about salary in the office.” HR expert Yang also reminds us that paychecks are your own business. It is unwise to share this information with others, no matter how close you are.
To summarize, Yang advises office workers to be more aware of the image they project when talking to colleagues, “When you share your personal life, it will be recorded on your invisible resume and may slow down your career progressing.”The author quoted Yang Yudan in the text to ________.
| A．show his admiration for her |
| B．make an argument with her |
| C．support his own viewpoint |
| D．build up his fame |

| B．He broke the rules made by the company. |
| C．He was such an honest person that he told the truth. |
| D．He treated his colleagues as family members. |
What is the author's purpose in writing the text?
| A．To draw people's attention to their behaviors in public. |
| B．To advise office workers to be aware of the image they project. |

“It is one of the few bright spots in the Chinese economy，” says Zeng Ming. He is talking about ecommerce. Mr. Zeng, the chief strategy officer for Alibaba, a giant Chinese Internet firm, predicts that digital transactions on his firm's platforms will top 1 trillion yuan($159 billion) this year—more than Amazon's and eBay's combined. That is a bold claim, but consider what happened on Singles Day.
Invented a few years ago by students and seized upon by digital marketers, this festival for lonely hearts falls annually on the 11th day of the 11th month(since 1 is the loneliest number). It is like St Valentine's Day, only worse. Singletons show each other with tender gifts: a barrage of pearls; a storm of sweets.
This November 11th they spent a surprising 19 billion yuan on Alibaba's online platforms—a fourfold increase on a year ago, and more than double what Americans spent online last Cyber Monday(the Monday after Thanksgiving, when retailers urge Americans to shop online). About 100 million purchases were logged, accounting for 80% of the packages shipped that day. Couriers(快递员) were buried in parcels.
So life is good for China's etailers. Then? Not exactly. The number of digital marketers is increasing and online sales are booming. Consumers are enjoying lower prices, better service and more variety. The problem? The pressure on profits in Chinese ecommerce is worse than in America, reckons Elinor Leung of CLSA, a broker. “Almost no one makes money，” she says.
The fiercest battles are being fought between online retailers and their bricksandmortar(实体的) rivals. Dangdang, a firm that resembles Amazon, and 360buy, another online retailer, have cut prices fiercely. Tencent, a cashrich online giant known for its instantmessaging software, is splashing out to win market share. 360buy has also just raised $400 millon from investors to do the same. But it is unclear how much longer such firms can burn through capital. What's the best title of this passage?
| A．The Ambition of Alibaba |
| B．Fierce Competition between Retailers |
| C．A New Festival for the Singles |
| D．Chinese Booming Ecommerce |
According to Zeng Ming, this year Alibaba will ________.
| A．outweigh Amazon and eBay in worldwide influence |
| B．rank top among all the Internet firms |
| C．have more than 159 billion dollars' sale |
| D．create another sales miracle just like the one on Singles Day |
How many packages were shipped on November 11th from Alibaba's online platforms?
| A．About 80 million. | B．About 100 million. |
| C．About 125 million. | D．About 180 million. |
What's the author's attitude towards online retailers in China?
| A．Optimistic. | B．Concerned. |
| C．Sympathetic. | D．Indifferent. |
On a sunny day last August, Tim heard some shouting. Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea.
Two 12yearold boys, Christian and Jack, rowed out a boat to search for a football.Once they'd rowed beyond the calm waters, a beach umbrella tied to the boat caught the wind and pulled the boat into open water.The pair panicked and tried to row back to shore.But they were no match for it and the boat was out of control.
Tim knew it would soon be swallowed by the waves.
“Everything went quiet in my head，” Tim recalls(回忆)．“I was trying to figure out how to swim to the boys in a straight line.”
Tim took off his clothes and jumped into the water.Every 500 yards or so, he raised his head to judge his progress.“At one point, I considered turning back，” he says.“I wondered if I was putting my life at risk.” After 30 minutes of struggling, he was close enough to yell to the boys, “Take down the umbrella！”
Christian made much effort to take down the umbrella.Then Tim was able to catch up and climb aboard the boat.He took over rowing, but the waves were almost too strong for him.
“Let's aim for the pier(码头)，” Jack said.Tim turned the boat toward it.Soon afterward, waves crashed over the boat, and it began to sink.“Can you guys swim？” he cried.“A little bit，” the boys said.
Once they were in the water, Tim decided it would be safer and faster for him to pull the boys toward the pier.Christian and Jack were wearing life jackets and floated on their backs.Tim swam toward land as water washed over the boys' faces.
“Are we almost there？” they asked again and again.“Yes，” Tim told them each time.

For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does.
In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin(褪黑素), a chemical that helps us sleep.
However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom—even the one on the alarm clock or the charging indicator on your cellphone—could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes.
“This is particularly worrisome in populations such as young adults and adolescents, who already tend to be night_owls，” said researcher Brittany Wood at Rensselaer Polytechnic Institute.“Lack of sleep among teens is leading to depression, selfharm, low concentration and poor performance at school，” she added.
While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph.
Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light.According to the passage, we can know ________.
| A．it's a good habit to play with smartphones or iPads late into night |
| B．scientists suggest we should avoid using smartphones or iPads |
| C．darkness makes a great impact on the amount of melatonin |
| D．the sun was the only source of light in ancient times |
the sun was the main source of light.”可知D项为错误结论。Which of the following is TRUE according to the passage?
| A．The darker it is, the more melatonin will be produced. |
| B．The lighter it is, the more melatonin will be produced. |
| C．The more melatonin you have, the worse you'll sleep. |
| D．The more electrical equipment you have, the more melatonin will be produced. |
The underlined part in Paragraph 4 refers to those ________.
| A．who are young adults or adolescents |
| B．who don't perform well in school |
| C．who are addicted to a television or laptop |
| D．who are short of sleep at night and perform poorly in daily life |
In the writer's opinion, which is a correct suggestion?
| A．You should go to bed when the sun goes down. |
| B．You should use an orange or red light electronic screen. |
| C．You should wear a pair of blue sunglasses when sleeping. |
| D．You should avoid blue light as possible as you can before bedtime. |
