As populations increased in large cities in     1     nineteenth century, building subway lines was a way     2    (move) people from one area of a city to another quickly and efficiently. The first major subway system, the London Underground,     3    (start) in 1873 using steam trains. Subways caught on quickly in London. From 1896, it was changed in favor of an electrical system. Today’s subways around the world now work on     4    (electrical). Passengers can rely on the regular schedule of subway trains while     5    (avoid) traffic on busy city streets.

Two of the world’s earliest subways were built in Paris and New York. When the Paris Metro opened on July 19, 1900, citizens were proud of the     6    (impress) and beautifully decorated station entrances.    7     the first New York subway consisted     8     only 14.5 kilometers of track in 1904, today, it is the world’s largest subway system.

Today, subways are still popular with passengers. The Tokyo subway is the     9    (busy) in the world, with 3.2 billion riders a year. Close behind     10    (be) subways in Moscow(2.4 billion), Seoul (2.1 billion), and New York City (1.6 billion).

Janet went down the long set of     1     (stair), surrounded by people. She held onto the rail, anxiety growing gradually for this was her first time taking the subway.     2     everyone seemed to think it was normal. Soon she reached the platform     3     other passengers stood and waited. A bell     4     (ring) a couple minutes later, and a voice came over the loudspeaker, saying that they should step back and wait. The lights of the approaching train rapidly grew     5     (close). Things were getting interesting.

The train whistled past the passengers, slowing to a stop     6     the end of the platform. The doors slid open, and a crowd of people exited. With those people     7     (rush) out, the new passengers hurried onto the train. Janet went with them. The doors shut moments later, and the     8     (friend) voice came over the loudspeaker inside the train, warning them     9     (stand) back from doors. Janet grabbed onto the nearest pole, since there were no seats for her.

She looked around the crowded train and supported     10     (she) as the train began to move along. After a few minutes, she smiled, enjoying the ride. It was actually pretty fun after all!

Beijing, together with Zhangjiakou, succeeded in getting the chance to host the 2022 Winter Olympic Games,   which   speeds   up   the   development   of   Zhangjiakou   City.   Word   came         1       the   Beijing- Zhangjiakou high-speed railway, located in North China, is now       2     construction, and is expected to be completed by 2020 in       3       (prepare) for the cities to host the 2022 Winter Olympics.

Starting from Beijing North Railway Station and heading west through the Great Wall, the project is     4     (probable) the biggest challenge ever. Its designers say that the explosions needed       5    (dig) the tunnels will not have a negative effect on the structure.

The railway line has a   length of 174 km as a double-track passenger line, with ten stations along its route. Enjoying       6       total investment of 31.17 billion yuan ($5 billion), the trip between the two cities will only take 40 minutes       7       the train will travel at an average of 250 km/h.

According to the plan, the high-speed railway will have two branch       8    line) — one is to Yanqing Station and the other to Taizicheng of Chongli, where the Olympic Village lies. The full railway,    9     (include) a 70-kilometer section through Beijing,       10     (complete) in four and a half years.

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.

Traffic can be dangerous for all of us.There's nothing     1    will ruin your day faster than a traffic jam,and it's even.    2    (bad)when there's seemingly no reason for it. However,there's a lot of science behind traffic.Although understanding it might not make sitting    3    the car any better,it can teach you how    4     (avoid)some of the mistakes we make while driving.

The way we drive into a line of traffic causes    5    (problem).Whether you're driving from the left or the right,chances are good that you're causing all sorts of problems.When most people see that they need to drive into a lane,    6    (they)natural   reaction is to do it right away.They brake,slow down,speed up,and change lanes in   between oncoming traffic.According to the Department of Transportation,that's     7    （complete)wrong.Sudden slowing    8    （cause)traffic to slow down.Other cars have to   brake.So what should you do?Wait until the last minute.If you do that, traffic will fall into    9    more natural pattern called a“zipper merge",    10    (mean)there are no surprises,no sudden braking,and a smoother transition from one lane to another.

China is a land of bicycles. People use their bicycles to get around. For many, it is the     1    (easy) way to travel around. Bicycles also come in different colors—silver, green, red, blue, yellow     2     you want. It’s fun watching people biking. They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks. And bicycles allow people the     3    (free) move about that other vehicles can’t provide.

Last Saturday, I jumped up on my newly-bought bicycle seat and started home. It was the first time that I     4    (ride) a bike here. My first ride home was orderly. To be safe, I stayed with a “pack” of bikers while cars on the streets came     5    (run) swiftly out of nowhere. I didn’t want to get hit. So I took the ride     6    (careful). Crossing the streets was challenging. As you know, the streets were wide. So crossing took time, skill and     7     little bit of luck.

I finally made it home. The feeling     8     the bicycle was excellent     9     felt the air hitting my face and going through my hair, it seemed as if I were on top of the world as I passed by     10    (place) and people. Biking made me feel alive.

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?
