6 . One weekend, a woman headed for her hotel room carrying a bucketful of coins she won at a slot machine. As she was about to walk into the _________ she noticed two men already aboard.

Both were _________ and one of them was a very, very big figure. She first thought: "They are going to _________ me." Then she comforted herself: "They looked nice."

But fear seized her. She stood and stared at the two, anxious and ashamed. She hoped they didn't _________ her mind. Surely they realized her hesitation about _________ them. With an effort of will she picked up one foot and _________ the elevator, turning her back to them.

Seconds passed. The elevator didn't move. Panic _________ her.

"I'm about to be robbed!", her heart _________ .

"Hit the floor", one of them said. Her sweats poured... Without delay, she threw out her arms and _________ on the carpet, the bucket of coins flying upwards. A __________ of coins rained down on her.

"Take my money and __________ me," she prayed. One of them said __________ : "Ma' am, if you'll just tell us what floor you're going to, we'll __________ the button." He couldn't help laughing.

__________ , she struggled to her feet. "I asked my man to hit the button for our floor. I didn't mean for you to hit the floor." He bit his __________ , having a hard time not laughing.

She was too __________ to speak. She wanted to make an apology, but words __________ her.

They helped gather up the coins and refill her __________ . When the elevator arrived at her floor, she slid to the room, hearing them laughing.

The next morning a bunch of roses were delivered to her room. Attached to the roses was a card __________ :"Thanks for the best __________ we've had in years." It was signed, Eddie Murphy& Michael Jordan.

Xiazhuang,     1     (surround) by steep cliffs about 1,000 meters high, is a remote village in Chongqing. There used to be only one pathway out of the village and villagers risked their lives     2     they walked to the main town.

In 1997, Mao Xianglin made a decision to help villagers out of     3     (poor) by building a road. The construction work was more difficult than they imagined. Without any professional equipment, Mao led the villagers to build this road     4     their bare hands and six lives were lost during the process. In 2004, after seven years of hard efforts, the 8-kiloneter-long road linked the village, located at the bottom of a valley, to the outside world. The dream of     5     (generation) was fulfilled. But for Mao, building a road     6     (be) the first step towards prosperity. In 2014, after consulting experts, he decided to develop orange planting in the village. About 100 migrant villagers came back to plant fruit. The orchard now covers     7     area of around 43.3 hectares.

Mao has a     8     (big) dream not only let villagers go out,     9     bring tourists in. Nineteen rural houses in the village     10     (transform) into homestay for tourists up to now.

With the joint efforts of Mao and his fellows, the villagers in Xiazhuang have become better off than before.

8 . There is one question that most parents seem to fear more than any other when it comes to talking to their kids about money.     1     If you said "How much money do you make?", you are exactly right, according to Jayne Pearl, author of several books about what she calls financial parenting.

There are two main reasons why most parents don't talk to their kids about money and help them develop critical financial skills, said Pearl.     2     Second, many parents feel like they don't know a lot about money and then don't have the confidence that they can teach their kids about it.

    3     For some answers, we asked some kids how they would handle things if they were in charge. Grace Szostak, who just started middle school this year, said she would get one of those toy cash registers and have her kids do a little role play with it, selling stuff to each other to understand the concept of money and learn how to count it.

Pearl said parents shouldn't hesitate to talk to their kids about the mistakes they've made, including the risks of credit card debt.     4     . Its goal, she believes, is to start teaching kids about financial responsibility, but it's better not to connect the weekly money to grades and behavior.

If you get past your insecurities about money and eventually talk to your kids, they'll definitely benefit. Kids are ultimately going to need to know how to handle their own money.     5    

9 . Boston wants to be smarter. The city has taken advantage of tiny sensors, big data and other technologies to become more responsive to its residents' needs. But technology alone is not sufficient to make today's cities livable. Boston has discovered that it also needs to reach the old-fashioned low-tech community and integrate that technology with city life.

Kris Carter, co-chair of the Mayor's Office of New Urban Mechanics, rolled out Boston's smart city program in 2014.It started with an app that residents could download to report locations where sidewalks needed repair. The city checked those reports and ranked them in a database, which repair workers used to prioritize (确定优先顺序) their work.

The system worked beautifully，except for one problem: most of the alerts came from wealthier neighborhoods, where the concentration of smartphone-equipped residents was highest. "The complaints that had been coming in from the app didn't always reveal the greatest community need for repairs," explains Carter.

Boston's high-tech initiatives shouldn't disproportionately (不成比例地) benefit the already well-resourced. Under Carter, technology is getting into the city's functioning and daily life, but with a special eye to serving those populations and neighborhoods that need the most support. "What we want to know is how to target problems in a smart way that addresses both needs and equity (公正) goals," he says.

Carter's group has moved away from the model common to many smart city initiatives of letting tech-savvy (精通科技产品的) residents and high-tech companies drive the process. Instead，they run meetings in local libraries and other public spaces to find out what problems people in different neighborhoods care about solving. When it came to sidewalks, Boston introduced a second method of collecting repair tips. In addition to its smartphone app, it hired people to get out and walk the city's 1,700 miles of sidewalks to take notes on their condition.

Whether using low-tech or high-tech approaches, says Carter, to stay smart, a city needs to continually reassess its options to spot opportunities to improve residents' lives.

10 . Stingrays are an instantly recognizable fish, with their pancake-like bodies that swim gracefully through the water. Their flat bodies allow them to sit on the bottom of the ocean, river or lake, disguising themselves to predators (食肉动物) swimming above as they hunt their prey (猎物) on the floor. Their eyes sit on the top of their body, while their mouths are on the bottom. They each have a long tail with a toxin-filled barb (充满毒素的倒钩). When they feel threatened, they can lift their barbed tails upward and injure potential predators. Most species of stingrays sport dull colors that help with disguise, though some do have more lively colors. Stingrays eat prey like worms while freshwater stingrays eat insects as well.

As those creatures move through the water, they generate bioelectric fields. Stingrays are able to detect these bioelectric fields of the animals around them using a network of special sensory organs called ampullae of Lorenzini. These organs are small, fluid-filled electrical receptors that are located near the stingray's mouth and look like tiny black holes in the animal's skin. Once they've located and captured their prey with the help of these sensory organs, stingrays use their hard teeth to break the shells of their victims, and can even chew their meal.

In 2006, Australian television personality Steve Irwin died when a stingray's barbed tail pierced his heart. Irwin was being filmed for a show called "Ocean's Deadliest" when he swam too close to a stingray. However, death from stingrays is rare. A stingray's poison is generally only deadly when its barb pierces people's neck or chest. Otherwise, contact with a stingray's. barb anywhere else on the body causes pain similar to a jellyfish (水母) sting.

Scientists also believe that stingrays have the ability to detect the Earth's magnetic fields and the orientation of electric currents generated by objects in the water. They could then use that information to navigate in the open ocean. However, this ability could potentially cause problems for the animals as offshore energy technologies like wind and wave energy become more popular, thus disturbing stingrays' ability to accurately detect their surroundings. This could influence stingrays' feeding and migration patterns.
