The airplane     2     (invent) by Orville and Wilbur Wright in 1903.     3     first airplane, Wright Flyer I, flew 36.5 meters in 12 seconds. After that, the two brothers kept     4     (improve) their airplanes. They     5     (fly) in public in France in 1908, and started taking passengers with them. From then on, many other people made great efforts to improve and develop airplanes. Thanks to their efforts, airplane technology developed     6     (extreme) fast.

Today, airplanes have many different     7     (apply). People can use airplanes to travel to other countries, send urgent mails and help people in danger. They use airplanes to send water, food, medicine, etc. to cities     8     urgent (紧急的）help is needed. However, airplanes are not only used in positive ways,     9     they are also used to fight wars.

Many things     10     (change) since the invention of the airplane. Airplanes have made travel or transport faster. Airplanes have really changed our lives.

AirCar is the latest generation flying car     1    transforms from road vehicle into air vehicle in less than 3 minutes. Useful for leisure and self-driving     2    (journey), the vehicle can go from driving to flying mode with the click of a button. The fifth generation flying car designed by Professor Stefan Klein     3    (complete) two flight tests at Piestany airport in Slovakia so far.

The two-seat AirCar     4    (weigh) 1,100 kg and can carry an additional load of 200 kg per flight.     5    (power) by a BMW 1.6 L engine, the car-plane has an effective power output of 140 HP. The estimated travel range of the vehicle is 1,000 km       6     the flight consumption is 18 liters per hour. AirCar can transform from a ground-based vehicle to aircraft with its speed     7    (reach) up to 200 km/h. But most importantly, the stability and controllability of the AirCar is     8    (access) to any pilot.

“With AirCar you will arrive at your destination     9     the trouble of getting a ride to airport and passing through commercial security. You can drive your AirCar to the golf course, the office, the shopping centre or your hotel and park     10     in a normal parking space,” said Anton Zajac, Klein Vision’s co-founder, investor and pilot.

Half a million Londoners travel to and from work by bike every day. Since the introduction of the Congestion Charge in 2003, the capital city     1    (see) an almost 50 per cent increase in the number of people commuting by bike.

The growth in cycling can partly be attributed to the launch in 2010 by Transport for London of the Barclays Cycle Hire System throughout the city's center.     2    (station) around the city, bikes can be registered     3     the TfL website, and regular users can buy access for 24 hours, 7 days, or one year. Users are then posted     4     key to release the locking system on the bikes.

Of course, London isn't the only place     5     cycling has taken off: people cycle to work on towns   and cities across the UK. In 2008,     6    (promote) the benefits of cycling more     7    (wide), the UK government     8    (organize) a competition to select the country's first cycling town. The city of Bristol won and received money to improve     9    (it) cycling infrastructure — more cycle lanes and increased parking     10    (spot) for bikes, etc.— and make cycling on roads generally safer.

While     1    (visit) Hangzhou's West Lake and its surroundings beautiful hills, you'll understand     2     it's been a great source of inspiration for artists, poets and philosophers throughout Chinese history.

Though     3     rest of the country is moving from two wheels to four, cycling culture is prosperous in Hangzhou. The city     4     (develop) China's first bike-sharing system in 2008. It’s since grown into the world’s     5    (big) and one of the world’s best public bike systems.

Hangzhou grows some of China's finest green tea—Longjing. Every spring, before the traditional Qingming Festival, tea     6    (love) from all over the country come to Longjing, a village     7       lies just south of West Lake, for the first cut of top-quality tea. During tea season—     8    (usual)late March and April—the air is fragrant with smell from the tea, when leaves     9    (pick) and roasted in the village.

What annoys you most in life? A new survey on annoying things has some interesting findings. The report     1     (divide) into a number of categories. Transport comes fairly high up in the list, with buses, planes and trains all capable     2     driving us mad. Some of the things we find most irritating (令人恼火的) about buses include missing a bus,     3    (particular) after running to the bus stop, and people in buses who crowd near the entrance     4    (refuse) to move down to the end of the bus. 

The airport is also a place that can really wind us up. Being hit by out-of-control luggage carts, or being caught on the ankles by someone who can’t control them properly is enough to make us see red. Getting in     5     slow-moving queue to check in our baggage when our flight is about to leave     6     (be) also enough to make our blood pressure soar.     7     (delay) flights are obviously annoying, but airlines that refuse to keep us up to date with the latest travel information make us even     8     (angry). 

The train     9     (cause) bother as well. Blocked toilets, buffet cars with no sandwiches and passengers     10     make loud mobile phone calls all appear on the list.

You may ride on your bicycle in a rush to get to school every morning. You may fight to get a bit of space on a bus or on the subway. You may also watch taxis move their way     1     (slow)through traffic jams. No matter where you are, all big     2     (city) around the world have traffic jams these days.

Although they all have their problems, many cities also have a type of transportation that has become a cultural icon.

In London, to avoid the traffic above ground, people use the “underground”. The city has     3     oldest and most complicated underground railway system in the world and it is the pride of many Londoners.

New York is famous for     4     (it) yellow cabs (出租车). They serve as a quick and easy way of     5     (get) across Manhattan, where the subway doesn’t take you everywhere. Stopping a cab is easy: just stick out your arm like you do in any city.     6    , with over 12,000 yellow cabs in the Big Apple (纽约别称), there     7     (be) also a lot of traffic jams.

Since 1873 when the first cable car     8     (start) public service, the slow and noisy vehicle has been a symbol of San Francisco.     9     once damaged by a serious earthquake and challenged by cars, it is never caught in traffic jams and provides     10     (good) views than the subway.

Europe offers amazing scenery, and much of it     1    (connect) by rail. For that reason, many travelers insist that a Eurail Pass is the best way     2    (go). Eurail is the brand name of a train pass that can be purchased and used only     3     non-European residents. My parents experienced the     4    (convenient) of a Eurail Pass as they traveled through eight countries in three weeks. They loved the ease of simply getting on the train and     5    (show) their passes.

How can you get a Eurail Pass? You can buy it in Europe, but it’s more expensive. It’s     6    (good) if you order it before you arrive and have it     7    (mail) to your home, office or hotel. You can choose the length of time that you want the pass to be valid. It’s not necessary, though, to state     8    (exact) when your travel will begin. You take care of that at the train station before you embark on(开始) your first train trip. After that, just sit back and enjoy beautiful landscapes from the comfort of your seat.

According to     9     passenger, “A Eurail trip is the perfect way to explore Europe and its wonderful cities,     10     is a journey full of breathtaking adventures.” Are you ready to begin your adventure?

Even pancake sellers are found     3    (use) Alipay. The bikes themselves are not new,     4    the operating model of bike-sharing is innovative. Chinese companies have surprised the world with the business model of bike-sharing which     5     (include) high technologies, and are entering overseas markets such as Singapore and Britain. The launch of high-speed trains has a       6    (big) influence on people’s choice of traveling than expected.
