6 . The Silk Road is arguably the most famous long-distance trade route of the ancient world. This passage connected Europe in the West with China in the East, and allowed the exchange of goods, technology, and ideas between the two civilizations. Although merchants could make huge profits travelling the road, it was not without risk.
The main Silk Road started in Chang’an (known today as Xi’an), the early Han capital. Travelers commencing their journey from this city could take a northern route that would take them across China’s northwestern provinces. After this, they would face the Gobi Desert, arguably the greatest danger of the Silk Road.
The Gobi Desert, the largest desert in Asia, consists mainly of rocky, hard earth. This feature made it easier for traders to travel across, compared to sandy deserts like the neighboring Taklamakan Desert. Like other deserts, the Gobi Desert is dry and hot, and therefore the biggest challenge travelers faced was obtaining enough water for themselves as well as for their camels.
So, rest stops were created along the route, allowing travelers to rest, eat and drink. These places also promoted the exchange of goods, and even ideas, amongst the travelers who stopped there. Usually, the rest stops were placed within a day’s journey of each other. In this way, travelers could avoid spending too much time in the desert, which would make them targets for robbers, another danger of the Silk Road.
Once through the Gobi Desert, travelers would continue their journey into Iran, Turkey, and finally Europe. While this part of the journey may have been less dangerous, it is not entirely without its perils (风险).

9 . Most of Florida is a flat peninsula (半岛) with water on three sides and houses built as close to the shoreline as possible. For one thing we are more frequently the target of hurricanes than any other state; for another, our geography makes us more easily to be hurt by rising seas.
A news story about climate change in Florida popped up. Historically, scientists believed mangroves (红树林) didn’t live farther north than Cedar Key, in the middle of Florida’s Big Bend. But that’s not the case anymore. Samantha Chapman, a biology professor who’s been studying how Florida’s mangroves have been migrating (迁移), found them up near the St Mary’s River, which forms the border between Florida and Georgia. It seems that they soon be marching through Georgia and becoming a thriving new component of coastal habitats.
But a coastal biologist named Blair Witherington took issue on the matter. The mangroves weren’t spreading into a new territory, he pointed out. They were entering areas that had been classified as saltmarsh (盐沼), where the landscape was dominated by cordgrass. Saltmarsh and mangrove create very different habitats that attract a very different set of animals. “When one community replaces the other, this diversity is lost,” Witherington remarked. Changing the animals’ habitat has the potential to influence the whole food chain, making a widespread difference.
What was driving this? “Mangroves can survive a short freeze, but not a prolonged, hard freeze. By combing through the weather records kept by the state’s orange juice industry, biologists have been able to document that Florida is having fewer prolonged hard freezes than it used to. Then the mangroves have adapted by expanding their range.” Samantha explained.
“They’ve adapted in another way, too. Not only are the mangroves spreading into areas that once were unfriendly to them, but they have also changed their life cycle to speed things up. Normally it takes them about 15 years of growth before they start making seeds. Now, as they get into these marshes, they’re producing seeds when they’ re only a couple of years old,” Samantha said.
The problem with having too many mangroves by the sea is that climate change may overwhelm them. A study by the US Geological Survey said sea level rise could wipe out mangroves all along the Florida coast. So, here’s the question we humans have to consider: Nature is finding ways to adapt to how we’ve changed the climate. What are we doing to adapt to it? Or at least slow it down?
