“My wife's locked in,” explained Wilson calmly, “she's going to stay there till we move away.”

Michaelis was surprised to hear words like those from his neighbor. He tried to find out what had happened, but Wilson didn't want to explain. After seven he heard Mrs. Wilson's voice, loud and angry, downstairs in the garage. She was shouting at her husband.

A moment later she ran out into the dark night. Before Michaelis could do anything, it was over.

The car, as reported, didn't stop. Michaelis wasn't even sure of its color. He told the policeman later that it was light green. Another car heading for New York stopped and its driver hurried back to where Mrs. Wilson lay dead in the road.

“Crash！” said Tom “Good. Wilson'll have some business.”

He stopped at the garage.

“We'll take a look,” he said.

A wailing (恸哭) sound was coming from the garage — it was Wilson. “Oh, my god!” he cried over and over again.

“There's some bad trouble here,”said Tom, trying to look over the heads of the crowd.

Suddenly he made a strange sound and started pushing through the people. Jordan and I followed. Mrs. Wilson's body lay in a blanket on a table by the wall. Tom was bending over her. Tom turned to the policeman, “What happened？”

“A car hit her. She was killed instantly.”

“Killed instantly,” repeated Tom.

“She ran into the road,” said Michaelis. “There were two cars. The one coming from New York hit her.”

Another man said, “It was a big, new, yellow car.”

“Did you see the accident?”

“No, but the car passed me down the road. It was going very fast.”

Some of this conversation reached Wilson.

“You don't have to tell me！I know what kind of car it was!” he shouted.

The muscles in Tom's shoulders tensed. He walked over to Wilson and took hold of him.

“Pull yourself together,” he said quietly. “I got here a minute ago, from New York. I was bringing you that coupe (敞篷车). That yellow car I was driving this afternoon wasn't mine.”

1 A few cookies in the afternoon might seem like a harmless pleasure, but they could have lasting influence on global biodiversity (生物多样性). Cookies often contain palm oil, the production of which is one of the fastest growing causes of deforestation. That in turn leads to reduced biodiversity according to a recently published study in Nature Ecology & Evolution.

2 Looking at data from 2000 to 2011, we found the number of bird species that became endangered due to land use activities increased by seven percent. We also studied the degree to which agriculture and forestry prevented carbon sequestration (封存) over the same period. We estimated (估计) that the opportunity costs, in terms of prevented carbon dioxide absorption on used lands, increased by six percent.

3 For both biodiversity influences and lost carbon sequestration, growth in international trade between world regions was a major driver, contributing 82% and 53% to the overall increases.

4 We found that global consumption (消费) trends are shifting from North America and Western Europe to Asia, the Middle East and Eastern Europe.

5 Another factor at play was that developed nations often effectively reduced the environmental damage caused by land-use activities through the purchase of raw materials from abroad.

6 Just as certain choices carry negative consequences, unintended though they may be, other choices carry positive ones. The public can make a difference — they can change the world with their choices. For example, we know that cattle farming is one of the largest drivers of biodiversity loss, and so reducing meat consumption will have a positive effect. Similarly, reducing the use of short-lived forestry products can reduce the growth of industrial wood farms, which often replace diverse forests with more homogeneous (同类的) plantations.

7 The findings will also help inform policy makers, particularly those involved in international environmental talks. Our paper shows clearly that this is a global phenomenon, and we need to treat it as such.

A remake episode（剧集）of All in the Family, set in 1976, recreated the Bunker family home in New York. Archie the conservative（保守的）loading-dock worker and his kindly wife Edith have an unexpected visitor David Brewster, who is the school friend of their son-in-law Mike. David is a Vietnam War draft dodger（逃避兵役者）who fled back home for Christmas. When Edith invites David to join them for the holiday dinner, Mike warns his friend not to tell Archie what he'd done - and to avoid such topics as politics, religion and war.

Archie, meanwhile, has invited his friend Pinky Peterson, who lost his son Steve in the war. Mike's worst fears are realized - David's secret is let out and the happy gathering quickly turns into a bitter argument over the war, with Archie yelling, “What he did was wrong！” Finally Pinky stands up. “My kid hated the war too,” he says. “But he did what he thought he had to do. So did David... if Steve was here, he would want to sit down with him. And that is what I want to do.”

All in the Family was first broadcast in 1971, two years before the United States withdrew from Vietnam. The very day ABC restaged the show in 2019, Congress had started impeachment（弹劾）against President Donald Trump, and the country found itself as polarized（分化）as ever. So much had changed in four-plus decades - and yet so little.

Back in the 1970s, of course, it was brave for a sitcom（情景喜剧）to take on such a sensitive topic as the war. There was no political content on TV, until the full-throated “angry white man” Archie Bunker broke into America's living rooms, proudly claiming, “I hate change.” He represented the conservatives who felt overlooked by the general public and Washington officials - and he broadcast his prejudices every week.

As a result, All in the Family quickly did more than become a top-rated Emmy Award-winning series. This show transformed the very nature of what could be broadcast into our homes, and paved the way for other shows with working-class as well as racially diverse characters. It touches problems that still confused our families and society, and seeks to understand and explain the very soul of America.

When it comes to road accidents, both drivers and non-drivers     36    （blame） for it. For one thing, it is not     37    （common） to find drivers paying little attention to the surroundings, thus inviting accidents. When     38     （face） with traffic jam, many drivers tend to aggressively push into other lanes or speed to pass cars. Or, some drivers speak on the phone,    39     results in divided attention. For another, some cyclists make the     40    （assume） that traffic laws do not apply to them and get their way. For instance, they never signal at turnings even     41     the pavement, ignore the condition of bicycles     42     carry an adult passenger. Actually, it is necessary to check the bicycles regularly to make sure it does work. And carrying a light load on bicycles makes it difficult     43    （control）. Pedestrians, on the other hand, fail to look both ways before     44    （step） into the road. In     45     word, we must all be aware of potential causes and act to prevent them. This is true of everyone. After all, all of us road users are to see to road safety.
