Paris has long been at the heart of the history of flight. It is where the Montgolfier brothers went up in the first hot-air balloon in 1783, and where Charles Lindbergh completed the first one-person transatlantic areophane journey in 1927. Next year, if all goes to plan, Paris will witness the birth of another industry________, when Volocopter, a German maker of electric aircraft, launches a flying-taxi service during the Olympic Games. At the Paris Airshow in June, Volocopter and some of its competitors displayed a new generation of________flying machines designed for urban transport.

The electrification of aviation (航空) has often been dismissed as a pipe dream, with batteries assumed too heavy a______for traditional fuel in an airborne vehicle. For longer journeys, that may well be true. Yet upstarts like Volocopter are betting that electrification can________a boom in demand for clean and quick air journeys over shorter distances.

The main form of a flying taxi under________, called an electric vertical (垂直的) take-off and landing (eVTOL) aircraft, is expected to carry up to four passengers plus a pilot. Powered by batteries, it is predicted to be both quiet enough to reduce complaints in crowded cities, and fast: capable of up to 300kph, enough to comfortably________a car, especially the one stuck in traffic. And optimists believe the absence of traffic in the sky will also make eVTOLs well-suited to ________ operation. They could prove handy for transporting goods, too. That vision has inspired________predictions. For example, Morgan Stanley, an investment bank, estimates global spending on eVTOLs could hit $1,000 billion by 2040!

Regardless of the above________expectations, challenges remain. One problem is technical certification, which is turning out to be a(n)________process as aviation regulators work on an entirely new form of aircraft. Late last year, due to regulatory delays and some other factors, Joby, a Silicon Valley startup, was forced to________its launch by one more year until 2025. Many have even longer to go. The bigger question is — is the business of flying taxis_______practicable? EVTOLs currently range in price from $1 million to $ 4 million. Some believe that their cost may come down as the industry develops. Brian Yutko of Wisk, a maker backed by Boeing, says that flying-taxi rides will be accessible to________in the near future. And Joby promises that its fares will be comparable to catching a common taxi. ________, there is an opposite belief that eVTOLs are likely to remain expensive. Some studies suggest the cost could end up as high as $7 per kilometer, many times a regular taxi fare. That means, even without a pilot, flying taxis may remain a convenience________only to a lucky few.

Let’s expect plenty more experiments with electric aircraft in the years ahead.

文章大意：本文是一篇记叙文。文章讲述了17岁的青少年Anika Puri发明Elsa——一种低成本的可以实时发现大象偷猎者的工具。

【推荐3】A 17-year-old teenager, Anika Puri, has invented a low-cost tool to spot elephant poachers (偷猎者) in real time. She won the 2022 Peggy Scripps Award for Science Communication for her model of a machine-learning driven software that analyzes movement patterns in thermal videos of humans and elephants. “I’m________excited by the________focusing on endangered species and environmental science.” Puri said.

During a recent trip to India, Puri realized that elephants were still being________for their tusks (牙). “I was quite taken aback,” Puri said, “Because I always thought, ‘well, poaching is________; how come it really is still such a big________?”

Over the next two years, Puri________the software EISa (short for elephant savior). This wildlife poacher detection solution is based on a________process: an EISa camera________to a mobile phone flies over a park on a drone and________the movements of elephants or humans. The software is four times more________than existing state-of-the-art detection methods. It also decreases the________for expensive high-resolution thermal cameras.

The 17-year -old’s invention has earned________from notable scientists. “Puri’s software is quite admirable,” says Jasper Eikelboom, an ecologist, “it’s quite________ that a senior high school student has been able to________something like this. Not only the research and the analysis, but also... being able to________it in the models.”
