题目内容
【题目】 It was a Saturday evening in March,just before sundown,when we heard the screaming. I was out walking with my wife,Melissa,and our golden retriever(猎犬),Kira,beside a lake when the peace was broken by a woman’s voice,calling out two names over and over.
We spotted her,almost immediately,three or four hundred feet away across the lake. Spring had come but there was still snow on the ground,the water covered by a layer of ice that had just started to thaw. Two big dogs were walking across it. They appeared to be quite old and were moving slowly. As we watched,the ice gave way beneath one dog and then the other,plunging them into the water.
We arrived at the scene a few minutes later,but the dogs already seemed to be showing the effects of the cold as they struggled weakly to escape. We realized that calling 911 would be useless—the dog farther out was in water about 20 feet deep and I feared neither of them would stay afloat long enough for the emergency services to arrive. Besides,I was probably qualified to carry out the rescue myself. I was practicing the kind of deep breathing my grandfather had taught me as I walked in. I wasn’t alone—Kira swam alongside me. Having Kira there was a huge support. We were able to go back to shore quickly.
The second dog was further out and I had to pause before I went back in. That’s when another technique I’d learned from my grandfather came into play. He’d taught me about a pressure point on the wrist that when pressed in the right way sends out an electrical signal,like a jolt of energy. That kept me warm as I set out again with,Kira. I maintained eye contact with the dog as we approached. With Kira’s encouragement,it followed us back. The owner was emotional—“I’m the luckiest woman alive!”she said.

【4】Who accompanied and helped the writer while saving the dogs in the water?
A.His wife.B.The dogs’owner.
C.His grandfather.D.His dog.
【答案】
【1】A
【2】C
【3】B
【4】D
【解析】
这是一篇记叙文。文章讲述了作者和妻子带着他们的金毛犬基拉在湖边散步时,营救一个女子的两只落水的狗的故事。
【1】
词义猜测题。根据上文Spring had come but there was still snow on the ground春天来了,但是地上还有雪,并结合常识可知,春天来了,冰雪应该开始融化。因此,thaw是指“融化”的意思。故选A。
【2】
细节理解题。根据第三段的We realized that calling 911 would be useless—the dog farther out was in water about 20 feet deep and I feared neither of them would stay afloat long enough for the emergency services to arrive. 我们意识到拨打911是没有用的——远处的狗在20英尺深的水里,我担心它们俩都不能在水面上待太久,等紧急救援人员赶到。可知,不拨打911是因为狗狗等不及紧急救援。故选C。
【3】
细节理解题。根据最后一段的He’d taught me about a pressure point on the wrist that when pressed in the right way sends out an electrical signal,like a jolt of energy. That kept me warm as I set out again with,Kira. 他教过我手腕上的一个按压点,当按压正确时,它会发出电信号,就像一股能量。这让我在和基拉再次出发时感到温暖。可知,作者从爷爷那学到的第二个技能是使作者暖和。故选B。
【4】
细节理解题。根据第三段的I wasn’t alone—Kira swam alongside me. Having Kira there was a huge support. 我不是一个人——基拉游在我旁边。有了基拉,就有了巨大的支持。和最后一段的That kept me warm as I set out again with,Kira. I maintained eye contact with the dog as we approached. With Kira’s encouragement,it followed us back. 这让我在和基拉再次出发时感到温暖。当我们走近时,我和狗保持着眼神交流。在基拉的鼓励下,它跟着我们回来了。 可知,是作者的狗“基拉”在水里帮助作者救援狗狗。故选D。

Driverless cars used to be the sort of thing you’d see in sci-fi films, but in 2020 they’re becoming a reality. Autonomous car technology is already being developed by the likes of Lexus, BMW and Mercedes, and we’ve even tested Tesla’s driverless Autopilot system on UK roads. Across the Atlantic, Google is developing its automated technology in the wild, and Apple is rumoured to be working with BMW on its own-probably automated-car.
Fully-driverless tech is still at an advanced testing stage, but partially automated technology has been around for the last few years. Executive saloons like the BMW 7 Series feature automated parking, and can even be controlled remotely.
With so much investment and interest in driverless technology, it’s easy to assume that self-operating cars are likely to happen soon, but they’re much further away than we might think. Before driverless vehicles go to market widely, manufacturers must deal with a range of technical and ethical challenges, and prevent the biggest threat to autonomous technology: humans.
The human problem
Humans present problems for autonomous cars as both drivers and pedestrians, and dealing with our unpredictable behaviour represents a significant challenge for the technology.
The Google Car is one of the most experienced autonomous vehicles. Even so, its interaction with human drivers has given rise to the exposure of one of driverless cars’ main weaknesses. The first injury involving the Google Car wasn’t due to a fault in its system, but human-error. While correctly waiting at traffic lights, Google’s self-driving car was hit by an inattentive driver and, in spite of its sophisticated array (复杂精密的数组) of sensors, there was little it could do to avoid the incident. Luckily, the accident only resulted in minor injury for a few of the passengers, but it’s a reminder that autonomous cars are at risk when surrounded by human road users.
Despite their sophisticated systems, self-driving cars currently have no plan B for human road users. Human drivers are able to interact with each other and make allowances, but also make countless, small mistakes when driving-mistakes to which current self-driving cars simply can’t adapt.
Dealing with pedestrians
The way human drivers interact with pedestrians raises difficult moral and ethical questions for car manufacturers-with implications.
Autonomous cars need to understand the way pedestrians behave, while also imitating the behaviour they’d expect from a human driver. “Everyone has a knowledge of how a human being is going to react, because we are all human beings,” says computer ethics commentator Ben Byford. “So if you walk out in front of a car, and presumably the car driver knows you’re there, they’re going to react in a certain way.”
“ If I walked out in front of a Google car travelling at 60mph, I have no real knowledge of how the vehicle will behave, so I’m effectively putting myself in danger.”
