In the southern part of France, away from the charm of Paris and the scenic Riviera, lies Toulouse, often referred to as “La Ville Rose” or “The Pink City.” Its nickname comes from the unique terra-cotta bricks used in many of its, buildings, giving the city a distinctive style.

Historically, Toulouse traces its roots back to the ancient times. It was originally established by the Celts in the 4th century BC and later became a significant Roman settlement. The city’s strategic position near the Germane River made it a well-known trading center in ancient Europe. By the Middle Ages, Toulouse had become a major center of trade due to its dye industry. This trade brought immense wealth to the region, and the city’s grand houses and public buildings from this era reflect is opulence (繁华).

However, Toulouse was not just a center for trade. Its history is marked with intellectual pursuits. By the 13th century, Université de Toulouse was established, making it one of the oldest universities in the world. The institution attracted scholars from various parts of Europe.

In modern times, Toulouse is famous for its aerospace industry. Home to Airbus, one of the world’s largest commercial aircraft manufacturers, the city is a center point in global aviation. This modern achievement connects with Toulouse’s rich history, showcasing a combination of the old and the new.

One of the most significant landmarks in Toulouse is the Basilica of Saint-Sernin, an architectural marvel from the Romanesque period. The church stands as a testament to the city’s religious significance during the medieval (中世纪的) times. Another notable part is the Capitole de Toulouse, which houses the city hall and a grand opera building. Its facade, made with the characteristic pink bricks, showcases the essence (本质) of Toulouse.

Despite its historical significance and achievements, Toulouse often remains overshadowed by other French cities. Yet, those who went to this southern gem find themselves fond of its rich history, vibrant culture, and the warmth of its inhabitants.

Visiting Toulouse offers an opportunity to step back in time while remaining firmly grounded in the present. It’s a city that embraces is past, cherishes its traditions, yet looks forward with optimism. In the European cities, Toulouse shines as a wonderful, yet irreplaceable one.

There is a place     1     (name) Dahailin (Huge Sea Forest) in northeastern China’s Heilongjiang Province. Deep in Dahailin is a magic al place,     2     it snows from October until March. There lies a small snowy village. In the snow, the old wooden     3     (house) look like white mushrooms (蘑菇). Bright red lanterns stand out upon the village’s white-washed background. The villagers there enjoy     4     (live) a free and pleasant life.

    1     (locate) in the northeast of the Tibetan Highland, Qinghai Lake is usually No. 1 on “Most Beautiful Lakes in China” list. It has very different scenery in different seasons. In spring, the surrounding mountains and wetlands take on a fresh green look with     2    (colour) flowers and white snow. In summer and autumn, the lake     3     (decorate) with golden clothing, as thousands of hectares (公顷) of rape flowers spread out from Qinghai Lake’s shores. In winter, snow and ice cover the surface of the lake, and the lake becomes quiet.

Construction of the Tower of Pisa began in 1173     1     Pisa was a center of power and wealth. But work was stopped several times because of wars. The eight-story tower was not completed until the late 1200s. The tower itself is made of marble (大理石) and     2     (weigh) 16,000 tons. However, the leaning of the tower was not for its weights     3     for the soil underneath. The ground is     4     (soft) on one side than on the other. The south side has sunk 6.1 feet below ground level in the past centuries. The north side has sunk 12.3 feet!

A new study reveals more answers about why Earth’s second largest ocean is expanding four centimetres.

That’s around the height of a golf tee. The width of a cracker. It’s also the amount that the Atlantic Ocean is expanding every year.

Now when you’re talking about an ocean that is 4,830 kilometres (3,000 miles) wide at its largest point, 4 centimetres (1.6 inches) is not much. But it is happening. So naturally, scientists want to know why.

Thanks to a new study, researchers think that they have the answer why. You could even call it a ‘hot take’. As in hot magma, or molten rock, deep under the ocean floor!

The study suggests that the expansion is being caused by magma(岩浆) bubbling up from under an underwater ‘mountain range’ called the Mid-Atlantic Ridge. Let’s start with what that ridge is.

Basically, the Mid-Atlantic Ridge is the seam between some very large tectonic plates. The ridge is also known as a plate boundary. As we’ve discussed before here, tectonic plates are essentially the platforms that our continents rest on. They are large pieces of the crust that are always moving in slow motion.

This movement is what causes earthquakes, for example. And the areas where the plates meet are where we tend to find things like mountains and volcanos, as well.

In this case, as the magma bubbles up from the mantle(地幔) below the crust, it is pushing the edges of both plates out of the way. As a result, the ocean is slowly getting wider.

This is a new finding. Before the study, scientists thought that the plates were being pulled apart—they were being dragged away from the ridge by forces occurring on either side of the ocean, not from in the middle.

Scientists still believe that this ‘pulling’ motion is happening. It is just that now, they feel that the bubbling magma is an important force as well. There is push and pull.

The scientists behind this study have been quick to point out that their research is only looking at a small cross-section of the ridge. It’s like a slice across it. What is happening right along this slice, may not be happening the same way up and down the entire ridge. But it is still really useful information—and how they got it is pretty cool.

Back in 2016, a research ship traveled to a very quiet spot directly over the ridge. Over five weeks, the crew dropped 39 seismometers on to the ocean floor. These devices allow them to ‘listen’ to the activity of the tectonic plates and what was beneath it. It’s like what a stethoscope does with your heartbeat, but for the planet. A year later, they retrieved the devices and looked at the data.

Then it was back to the lab to try and piece together what they learned. In the end, they have added to our understanding of how and why the Earth’s surface constantly moves. Even if it is only by about a little bit each year!
