1 . If you had boarded a passenger plane in 1950, you would have seen five people in the cockpit (驾驶舱): two pilots, a radio operator, a navigator and a flight engineer. Over the years, technical advances have gradually removed the need for the last three, leaving just two pilots. That has been the norm (标准) in commercial aviation for decades.

However, things could be simplified further — one of the two remaining pilots could soon go. Many military aircraft are already manned by a single pilot, and for commercial aviation this would mean stepping into a brave new world.

But how will airlines make this brave innovation come true? One way is to greatly increase automation in the cockpit, devoting more tasks to computers. Another is to shift the same tasks from the cockpit to the ground. “The latter approach seems to be more workable, at least in the short term, because much of what is required already exists,” says Patrick Smith, an airline pilot flying Boeing 767 aircraft. “A trained ground operator could observe a number of flights at once and even fully control the plane remotely if needed.”

It’s true that single-pilot operations could help airlines save money, but there is another reason which makes them quicken their pace for this crucial breakthrough. Boeing predicts a need for 600,000 new pilots in the next two decades, but by some estimates, there will be a deficit (赤字) of at least 34,000 pilots globally by 2025. Reducing the number of pilots on some crews or aircraft could lessen the impact of this.

Perhaps the biggest barrier to a single pilot will be selling the idea to passengers. In 2019, Don Hairis, a professor at Coventry University, conducted a survey on the prospect of flying on an airliner with just one pilot. Just a minority of participants said they’d be willing to take that flight, and the general idea was that removing a pilot increased the possibility of accidents. In the study, Harris concluded that the single-crew airliner would be still probably 20 years away.

When Zhi Yueying, then 19, went to the remote Niyang village in Fengxin County, Jiangxi Province,     1     (work) as a village teacher in 1980, villagers didn’t believe she would stay long because a number of voluntary teachers had left soon after their     2     (arrive) . However, it was not until three decades later     3     Zhi left the village and went to an even more remote village school in the mountains.

    4     (bear) in Nanchang city in 1961, Zhi applied to work as a teacher at the primary school in Niyang village after graduation, though her mother strongly disagree     5     her.

Over the past four decades, Zhi     6     (devote) herself to rural education. She won China Central Television’s Touching China awards that recognize the most     7     (inspire) role models in 2016. Besides, she     8     (award) as a model poverty fighter by the Central Committee of the Communist Party of China and the State Council, China’s Cabinet, earlier this year.

Zhi has a profound understanding of     9     importance of education in the mountains. “Education is a    10     (vital) important part of our efforts to help people escape poverty sand children who live in the mountains can only change their lives through schooling,” says Zhi.

In Xixian county, located in Linfen, Shanxi province, a smart pear orchard (果园)     1     (stretch) 33.3 hectares (公顷) has been developed with the     2     (assist) of the Shanxi Academy of Agricultural Sciences.

In this orchard, every pear is given     3     unique QR code that enables monitoring of the entire growth process. “The QR code serves     4     an ID card, recording the life of a pear,” said Wang Yibo, an agriculture official from the county.

    5     (establish) in 2020, the smart orchard is operated with the help of cutting-edge technologies such as the internet, big data, cloud computing and the internet of things. There are 64 villages in the county     6     rely on pears as their primary industry,     7     (account) for 80 percent of the farmers’ income.

So far, Xixian     8     (build) a smart agriculture integration platform made up of 12 systems, including water-fertilizer     9     (integrate) management, disease and insect monitoring, and the monitoring and evaluation of the quality of the land.

According to Wang, the platform not only helps with production but also promotes sales, as its tracking system can collect first-hand marketing feedback data. Pear farmers can learn about the market demand through the system to     10     (accurate) identify their customers and carry out targeted promotions.

6 . People will tell you the only way to really learn a language is to completely immerse(浸入)yourself in a country where that language is spoken. Not all language learners, of course, will have the opportunity to spend some time in an immersion environment.

That's where Babbel comes in. Babbel is one of the most popular language learning apps on the market for studying new languages at your own pace. The app emphasises real-life conversational skills, so you won't be stopped by grammatical structures and verb patterns.

Lifestyles differ from person to person. Some people, known as     1     natives, do a wide     2     of things online, such as     3     with friends, watching misreading updated news and interesting articles and so on. Take shopping as an example--it’s so     4     to compare quality and prices before buying. Some other people live their lives as go-getters. They tend to     5     goals when setting out to do something. Then they make a schedule and try hard to achieve it. As for life choices, in the case of Zhang Tian, he chose to be a     6     teacher in Guizhou province instead of going to big cities. Despite the poor facilities and unstable supplies of power and water, he has improved the learning lives for the students by introducing more attractive subjects like music, art and PE to the school.

    7     made him feel satisfied was that his students were able to read, speak and write in English and became more     8     in learning. Besides all these, he contacted charity organizations to set up a library and help sell local products online. As a result of the     9     he made, he became very popular among the villagers and was treated as one of them. Zhang Tian intended to stay for another year. He feels so happy that he     10     his heart, even though it may not be what others expected of him.
