1 . Bicycles are very popular around the world nowadays. People ride their bicycles for exercise and enjoyment. In some places, people use bicycles to get to work. In other places, bicycle riding is a very popular exercise to people who live in cities. But who invented the first bicycle?

In 1791, a Frenchman named Comte de Sivrac invented and owned the first bicycle. Mrs. Sivrac rode the bicycle in Paris. The handles and the seat were wooden. This bicycle was very difficult to move. A rider even had to pick up the front wheel to change direction. What's worse, the bicycle had no brakes for stopping or pedals for the feet! Riding a bicycle took great risk.

In 1817, a German named Baron von Drais de Sauerbrun made the first bicycle better. The seat became more comfortable. The wheel could now change direction. His ride in the forest took only one hour instead of three hours on foot, which surprised people at that time.

Sauerbrun brought this kind of bicycle from Germany to France. Then Denis Johnson, an Englishman, made a bicycle for women. It had space for their dresses to hang down. But these bicycles still had no brakes or pedals, and riders often got hurt. These bicycles and the people who rode them were not very popular.

It took another forty-five years for the bicycle to become popular. More than 100 years later, bicycle riding is more popular than ever. In fact, in India and China, there are still many more bicycles than cars.

3 . You probably know about the Titanic, but it was actually just one of three state-of-the art (最先进的) ocean ships back in the day. The Olympic class ships were built by the Harland & Wolff ship makers in Northern Ireland for the White Star Line company. The Olympic class included the Olympic, the Britannic and the Titanic. What you may not know is that the Titanic wasn’t even the flagship of this class. All in all, the Olympic class ships were marvels of sea engineering, but they seemed cursed to suffer disastrous fates.

The Olympic launched first in 1910, followed by the Titanic in 1911, and lastly the Britannic in 1914. The ships had nine decks, and White Star Line decided to focus on marking them the most luxurious ships on the water.

Stretching 269.13 meters, the Olympic class ship were wonders of naval technology, and everyone thought that they would continue to be so for quite some time. However, all suffered terrible accidents on the open seas. The Olympic got wrecked before the Titanic did, but it was the only one survive and maintain a successful career of 24 years. The Titanic was the first to sink after famously hitting a huge iceberg in 1912. Following this disaster, the Britannic hit a naval mine in 1916 and subsequently sank as well.

Each ship was coal-powered by several boilers constantly kept running by exhausted crews below deck. Most recognizable of the ship designs are the ship’s smoke stacks, but the fourth stack was actually just artistic in nature and served no functional purpose. While two of these ships sank, they were all designed with double hulls (船体) believed to make them “unsinkable”, perhaps a mistaken idea that led to the Titanic’s and the Britannic’s tragic end.

The Olympic suffered two crashes with other ships and went on to serve as a hospital ship and troop transport in World War I. Eventually, she was taken out of service in 1935, ending the era of the luxurious Olympic class ocean liners.
