It was a cold January in 1925 in Nome, Alaska. The town was cut off from the rest of the world due to heavy snow.

On the 20^th of that month, Dr. Welch ________ a sick boy, Billy, and knew he had diphtheria, a deadly infectious (传染的) disease mainly affecting children. The children of Nome would be ________ if it struck the town. Dr. Welch needed medicine as soon as possible to stop other kids from getting sick. ________, the closet supply was over 1,000 miles away, in Anchorage.

How could the medicine get to Nome? The town’s ________ was already full of ice, so it couldn’t come by ship. Cars and horses couldn’t travel on the ________ roads. Jet airplanes and big trucks didn’t exist yet.

________ January 26, Billy and three other children had died. Twenty more were sick. Nome’s town officials came up with a plan. They would have the medicine sent by ________ from Anchorage to Nenana. From there, dogsled (狗拉雪橇) drivers—known as “mushers”—would ________ it to Nome in a relay (接力).

The race began on January 27. The first musher, Shannon, picked up the medicine from the train at Nenana and rode all night. ________ he handed the medicine to the next musher, Shannon’s face was black from the extreme cold.

On January 31, a musher named Seppala had to ________ a frozen body of water called Norton Sound. It was the most dangerous part of the journey. Norton Sound was covered with ice, which could sometimes break up without warning. If that happened, Seppala might fall into the icy water below. He would ________, and so would the sick children of Nome. But Seppala made it across.

A huge snowstorm hit on February 1. A musher named Kaasen had to brave this storm. At one point, huge piles of snow blocked his ________. He had to leave the trail (痕迹) to get around them. Conditions were so bad that it was impossible for him to ________ the trail again. The only hope was Balto, Kaasen’s lead dog. Balto put his nose to the ground, ________ to find the smell of other dogs that had travelled on the trail. If Balto failed, it would mean disaster for Nome. The minutes passed by. Suddenly, Balto began to run. He had found the trail.

At 5:30 a.m. on February 2, Kaasen and his dog arrived in Nome. Within minutes, Dr. Welch had the medicine. He quickly gave it to the sick children. All of them recovered.

The First Tourist at Disneyland

Dave MacPherson may have been the first paying guest at Disneyland when the theme park opened its gates 50 years ago, but he didn’t even have time for one ride. In a hurry to get back to campus for a college class, he instead visited a restroom after spending hours in line and left without as much as a souvenir.

Still, the honor of being the first paid admission came with a special perk: a lifetime pass for four to Disneyland and other Disney parks as they opened.

“I was the most popular guy at the college,” said MacPherson, a retired journalist living in Monticello, Utah, about 240 miles southeast of Salt Lake City.

He’s taken full advantage of it scores of times, especially when he lived in California. Usage dwindled after he moved to Kansas City, Mo., to work for newspapers and radio. But being closer to California has made it more useful, and he last made the trip a year ago with his wife, Wanda. He receives a VIP renewal every January.

In 1955, MacPherson was watching televised coverage of the opening of Disneyland for the media and invited guests on July 17, 1955, a day before the park opened to the public. “I said, ‘Boy, I would like to go out there’,” said MacPherson, who figured he might draw a prize for standing first in line.

He drove his Simplex motorbike to Anaheim, arriving shortly before 1 a. m. to take his place in line an hour before anyone else showed up.

The crowd steadily grew overnight to about 6,000 people, and MacPherson made sure no one got in front of him. When the admission booth opened, a photographer for the Long Beach Press-Telegram captured him buying the first ticket.

Looking at the photo years later, he realized he had his own camera but didn’t use it. “Why didn’t I shoot some pictures?” he wonders. “I even forgot to ask Walt(Disney)for his autograph. I must have been balmy or something after staying up all night.”

The Internet has led to a huge increase in credit card fraud. Your card information could even be for sale on an illegal website. Websites offering cheap goods and services should be regarded with care. Online shoppers who enter their credit card information may never receive the goods they bought. The thieves then go shopping with your card number or sell the information over the Internet.

Computer hackers(黑客) have broken down security systems, raising Questions about the safety of cardholder information. 25, 000 customers of CD Universe, an online music retailer(批发商), were not lucky. Their names, addresses and credit card numbers were posted on a website after the retailer refused to pay the ransom(赎金) to get back the information.

Credit card firms are now fighting against online fraud. However, there are a few simple steps you can take to keep from being cheated.

Shop only on secure sites: send your credit card information only if the website offers advanced secure system.

If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The website address may also start with “https: / / ”-the extra “s” stands for secure. If in doubt, give your credit card information over the telephone.

Keep your passwords safe: most online sites require a user name and password before placing an order. Treat your passwords with care.

The first truly autonomous cars — vehicles that drive down the streets with no one behind the wheel — have finally arrived.

Waymo, which began life as Google’s self-driving car project, announced that it had let its driverless cars loose in parts of Phoenix, Arizona, with nobody in the front seats to take over in case of emergency. Members of the public taking part in a Waymo trial in the desert city in the south-west US will be able to order the vehicles to come through an app “in the next few months”, the group said.

Potentially one of the most revolutionary (革命性的) new technologies, as well as one of the most advertised, driverless cars have been at the centre of a race between big automakers and technology companies. But while a number of groups are testing the technology on the streets with back-up drivers behind the wheel, most believe the approach of full autonomy is at least two years away.

Google shocked the auto industry when it first showed a basic version of its driverless technology seven years ago, and it then invested more than $ l bn in autonomous vehicle research.

Rivals (竞争对手) admit it still has a technology lead, though skeptics question whether the artificial intelligence is good enough to respond to the many unforeseen events that could occur on the road.

Waymo believes it is the first company to reach a standard known in the driverless car world as level 4, meaning its cars can drive under full autonomy in preset areas that have been carefully mapped out and tested. Uber, General Motors, Aptiv PLC, BMW and others have been conducting testing to reach level 4, but all of them still keep a human in the driver’s seat.

Some people describe American society as a salad bowl while others see it as a melting pot. In a bowl of freshly tossed salad, all the ingredients are mixed together.    35    All the ingredients of a salad contribute to the finished product. They may be covered with the same dressing, but the green vegetables, tomatoes, lettuce and eggs can all be seen for what they are.

    36    Individual ethnic groups blend together, yet keep their cultural uniqueness. People may work together during the day at similar jobs and in the same companies, but at night they may return to their ethnic communities where their own individual culture directs their way of life.

The other concept, which is also used to describe American society, is the melting pot.    37    and yield a bit of what they were to become a new reality. The longer the soup is cooked, the better the taste and the more likely it will be for the mixture to dissolve. In this sense, America can surely be seen as a melting pot where people from all over the world come to live and work together forming one nation.

There are dozens of shared symbols.    38    In such a culture, symbols like the flag and the nation’s official song serve to break down the walls which separate ethnic groups.

Whether a salad bowl or a melting pot, America can best be described as a mixture of both.    39    

Recently, I flew to Las Vegas to attend a meeting. As we were about to arrive, the pilot announced with apology that there would be a slight delay before setting down. High desert winds had forced the airport to close all but one runway. He said that we would be circling the city for a few minutes waiting to land. We were also told to remain in our seats meanwhile with our seat belts     40    (fasten) because there might be a few bumps. Well, that few minutes turned into about forty-five minutes, including a ride that would make a roller coaster     41    (pale) by comparison.

The movement was so sudden     42    several passengers felt sick and had to use airsickness bags.     43    you might guess, that’s not a good thing to happen in a narrow space because it only serves to increase the discomfort of the situation.

About twenty minutes into the adventure, the entire airplane became very quiet. There was now a sense of anxiety and fear that could be distinctly noticed. Every passenger simply held on for dear life     44    one. A baby was having a good time! With each bump of the aircraft, he     45    let out giggle of happiness. As I observed this, I realized that he didn’t know he was supposed to be afraid and worried about his safety. He     46    thought about the past nor about the future. Those are     47    we grown-ups have learned from experience. He was enjoying the ride because he     48    (not teach)to fear it.     49    (understand)this, I took deep breath and sat back into my seat, pretending I was really on a roller coaster. I smiled for the rest of the flight. I even managed to giggle once or twice, which is much to the chagrin(恼怒)of the man sitting next to me holding the airsickness bag.
