In 1858, two men wanted to be elected United States Senator from Illinois. One was Stephen Douglas. The other was Abraham Lincoln. Douglas was already the Senator, but his term in office was up. Lincoln had once been a U.S. Representative but was then a lawyer in Illinois.

    The men agreed to have seven public meetings, or debates, in seven different cities in Illinois. That way, voters all over the state would have a chance to hear what each man stood for.

    The first debate was in Ottawa on August 21, 1858. The main thing the men disagreed on was slavery. Douglas believed that as new states joined the union, they should decide for themselves whether or not they wanted to be a slave state or a free state. Lincoln believed that slavery should not spread beyond the states that already had slaves. He said the United States could not survive as half-slave and half-free states.

    The debates drew large crowds in all seven cities. People in the entire country were paying attention. Lincoln lost the Senate race. The debates did, however, make him well known everywhere.

    In 1860, it was time to elect a new President. Lincoln won the Republican party's nomination(提名). Douglas won the Democratic party's nomination. The two men again faced each other to get the people's votes. This time Lincoln won. He became the nation's 16th President.

    The slavery issue was still causing bad feelings between slave and non-slave states. By the time Lincoln took over as President on March 4, 1861, seven states had left the union. A month later, the Civil War began.

    An autonomous vehicle designed for making local commerce deliveries was uncovered by Nuro. The vehicle is about the height of an SW but far narrower than a typical car. The electric car features four outside compartments（暗格）—two on each side -to hold separate deliveries. Each compartment can be tailored to a specific use, such as cooking a pizza or refrigerating a package.

    “We can use self-driving technology to deliver anything, anytime, anywhere for basically all local goods and services,” Nuro co-founder Dave Ferguson said. “Consumers used to be okay with two-week paid shipping. It became two-week free delivery, followed by one week, two days, and the same day. Now same-day delivery isn't fast enough for some customers.”

    Nuro isn't alone in building robots for local commerce deliveries. Earlier this month, Toyota, a Japanese car company, uncovered a concept vehicle that could be used for package delivery. A handful of startups—including Starship Technologies, Marble and Dispatch—are testing small robots for deliveries on sidewalks.

    Nuro's vehicle will likely face legal hurdles. Fully autonomous vehicles without a test diver aren't legal in California today, and many companies have shifted testing o states where regulators are more welcoming of autonomous vehicles, such as Arizona.

    Nuro expects to face fewer challenges because it doesn't carry passengers. Nuro's narrow size may also be helpful when navigating streets and avoiding pedestrians. The vehicle isn't equipped with any special features to communicate with pedestrians or other road users. Some companies have tested and patented solutions such as digital screens that signal the car's next move. Ferguson said his team conducted studies and found that such techniques could confuse people. Nuro believes it's better to make sure the car performs predictably, so that human drivers know what to expect from it.

    “We feel by creating this new technology that's going to enable this last mile delivery, we're going to be creating new markets and doing things that previously weren't possible,” Ferguson said. “This is not swapping out jobs with robots. It's creating new markets. There will definitely be new employment opportunities.”

    All over the world people enjoy sports. Sports help to keep people healthy, happy and help them to live longer.

    Sports change with the season. People play different games in winter and summer.

    Games and sports often grow out of people's work and everyday activities. The Arabs use horses or camels in much of their everyday life; they use them in their sports, too.

    Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers.

    Some sports or games go back to thousands of years, like running or jumping. Chinese boxing, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time.

    People from different countries may not be able to understand each other, but after a game they often become good friends. Sports help to train a person's character(性格). One learns to fight hard but fight fair, to win without pride and to lose with grace(体面).

    A ten-year-old boy from Howell, Michigan is being praised as a hero thanks to his persistence (坚持) that led to saving the life of an elderly neighbor. The event happened late in an evening when Danny DiPietro was being driven home from hockey practice by his mom.

    That's when the young boy noticed an open garage (车库) and a figure that he believed was a dog outside an apartment building near his house. Given the freezing weather, the young boy got a feeling that something was not right. But instead of dismissing it like most kids at his age, he insisted that his mother, Dawn, find out what was going on. Dawn tried to make Danny believe that no one would leave a dog out in such cold weather, but he refused to take no for an answer.

    Dawn finally gave in and decided to drive to the area with the family dog and see if there was any truth in Danny' s hunch (直觉). Sure enough, as she got closer to the apartment building she noticed a garage that was wide open and someone waving madly for help. Upon getting there, she realized that it was not a dog the young boy had seen, but Kathleen St. Onge. The 80-year-old woman had fallen down on some ice in front of her garage and had been lying there for two hours, unable to get up.

    Dawn rushed home to get her husband to help and called 911. The two then returned with some blankets to cover Ms. St. Onge, while they were waiting for the ambulance to arrive. Though still in hospital, the elderly woman is recovering well and forever grateful to Danny for following his hunch!

Sonya took Rupert, a rescue dog, back home three years ago, and soon found it liked attacking strangers and other animals, which she believed was caused by pain.

It took Sonya a year to develop a normal relationship with Rupert, during which she learned it was afraid of being left alone and also couldn't walk properly. Finally, she decided to take it to see a vet (兽医). After examining Rupert, the vet said its leg was broken, and it needed an immediate operation.

But when it had to go in for an operation on its leg, there was a problem—the vet Mike couldn't get near the dog. Mike and Sonya were left scratching their heads until one of them came up with an idea. Sonya said Rupert slept on a mouse suit so she suggested that Mike put it on.

At first, the dog barked wildly when Mike tried to operate on it in usual clothes. To make his patient feel at ease, Mike decided to dress up in the mouse clothes to see if it would be less worried. Amazingly, it worked. It stopped barking and immediately became good friends with Mike when he put on the suit. As a result, he was able to perform an operation on the leg safely and the result was quite satisfying.

After the successful operation, Mike hugged the dog around the neck, which isn't usually well-received by pets. Mike tried to be as respectful of its needs as possible and made time to give some attention. What Mike had done created a special experience or event in the dog's life.
