1 . Climate change is a global issue that affects nearly every aspect of life on Earth. The warming of the planet due to increased greenhouse gas emissions is leading to a range of impacts, from rising sea levels to more frequent extreme weather events. These impacts are not equal across the world, however, and some countries and communities are more vulnerable than others.

One of the most immediate impacts of climate change is food insecurity. Changes in temperature and precipitation (降水) patterns can affect crop yields (产量), leading to food shortages and price increases. Climate change can also affect fishing communities, as ocean temperatures and acidification (酸化) can harm marine (海洋的) life.

Climate change can also have broader impacts on human health, particularly if it leads to the spread of disease. For example, warmer temperatures can create conditions that are more conducive (有助于) to the spread of mosquito-borne (蚊子传播的) illnesses like dengue fever (登革热)and malaria (疟疾). Additionally, extreme weather events can cause injuries and illnesses, as well as disrupt healthcare services.

Finally, climate change can have significant economic impacts, particularly in sectors such as agriculture, forestry, and insurance. These impacts can have ripple effects (涟漪效应) throughout the economy, affecting businesses and individuals alike.

2 . The sharing economy is a trend that has been growing in recent years. This economy is based on sharing resources, such as cars, homes, and even clothing, rather than owning them outright. Some popular examples of the sharing economy include Uber, Airbnb, and Lyft.

The sharing economy has several potential benefits. For one, it can help reduce waste and increase sustainability(可持续性), as resources are being used more efficiently. Additionally, it can help provide more affordable options for consumers, as well as create new sources of income for people who may not have had access to traditional job opportunities.

However, there are also potential drawbacks to the sharing economy. Many of the workers in the sharing economy are considered independent contractors, which means they are not entitled to the same benefits and protections as traditional employees. Additionally, there have been concerns about safety and insurance coverage for both the workers and consumers using these services.

7 . The city of Pompeii is a partially buried Roman town­city near modern Naples in the Italian region of Campania. Along with Herculaneum, Pompeii was partially destroyed and buried under 4 m to 6 m of ash in the eruption of Mount Vesuvius in 79 AD.

By the 1st century AD, Pompeii was one of a number of towns located near the base of the volcano, Mount Vesuvius. The area had a large population which grew prosperous(繁荣的) from the region’s agricultural fertility(丰产). Many of Pompeii’s neighboring communities also suffered damage or destruction during the 79 AD eruption. The eruption occurred on August 24.

A study of the eruption products and victims indicated that at Vesuvius and surrounding towns heat was the main cause of death of people, previously believed to have died by ash suffocation(窒息). The results of the study, published in 2010, show that exposure to at least 250 ℃ hot surges at a distance of 10 kilometres from the vent(出口) was sufficient to cause instant death, even if people were sheltered within buildings.

In 1748, a farmer called Andre and his brother dug a cupboard made of metal. To their surprise, there are a lot of dissolved jewelry and ancient money in it.

This news took air. The farmers were thinking of the legend of disappeared Pompeii that ancestors told them. So, many archaeologists, historians, and even treasure hunters swarmed(蜂拥) there. In 1876, Italy government agreed with experts to dig the Pompeii out. Through a hundred years’ working, they dug the Pompeii out completely.

The historian Vanya said, “What a horrifying scene! Many people died when they are dormant(休眠的), and some people died behind the door of home. They were raising their hands and breathing ...”

Compared with nature, human seems small and weak. We don’t have enough power to compete with nature, so we should respect nature and protect the environment to lessen disasters.
