The Travels of Xu Xiake is a travel note     1     (create) by Xu Xiake,     2     geographer in the Ming Dynasty. After 34 years of travel, Xu Xiake left more than 600,000 Chinese words of travel notes. After his death, the materials were collected into Xu Xiake’s Travels by others.

This book is the first work to systematically investigate China’s geomorphology (水文地质学) and geology (地理学). In addition, the beautiful words also make it a masterpiece of literature,     3     is of great value in geography and literature.

The fresh and beautiful writing style used to describe things in The Travels of Xu Xiake     4     (make) readers love it.

Modern science and technology has also confirmed the accuracy of Xu Xiake’s records of geological landform and rock landscape.

The historical value of The Travels of Xu Xiake covers a wide range     6     levels. Apart from the observation of mountain landform, he also has     7     (detail) records on hydrological (水文学) distribution, river source exploration and the experience of the relationship between landscape and climate.

From these rich     8     (content), this travel note can leave a name in history. It is considered to be a work     9     (cover) literature and Science in the late Ming Dynasty.

The day of the first chapter of The Travels of Xu Xiake (May 19) is     10     (official) named as China’s Tourism Day.

6 . There are a lot of chemicals that can cause indoor air pollution. A recent project conducted has found over 900 different substances in our home are related to it. Many researchers have already examined the causes of indoor air pollution.     1    

It has been proved that different kinds of chemicals can be released by building materials and new furniture. Everything from painting and decorating products, bathroom cleaners and beauty products can contain these chemicals.     2     For instance, cooking generates a lot of harmful emissions, like frying meat in oil.

As a research from Denmark has highlighted, cooking, particularly roasting can damage our body. Roast dinners contain many potentially harmful pollutants.     3     When exposed to cooking emissions, people actually had DNA damage. It can be associated with cell repair processes that trigger cancer—causing genetic changes.     4     And what can we do with it?

As far as cooking emissions are concerned, no one is suggesting switching to takeaways.     5     For example, cooking meat at high temperatures with lots of fat produces more harmful emissions than boiling pasta. Besides, opening windows and using cooker hoods are preferable so that we can enjoy the roasted meat without those undesirable effects.

10 . Around 40 million tonnes of electronic waste, known as e-waste, is produced every year. This includes electrical or electronic equipment that has been discarded. But where does it all go? In the US alone, 100 million mobile phones, 41 million computers and over 20 million televisions are thrown into landfills in a year. Even for standard waste this is a big headache, because any materials that are buried in the ground can’t be easily recovered and recycled. Recycling electronics can save energy and means that less of Earth’s natural resources need to be mined.

Failing to recycle e-waste is extremely damaging the environment due to the nature of the materials used in modern devices. While heavy metals and chemicals improve a device’s safety and user experience, these components become poisonous if they’re not dealt with properly. Your old phones, Gameboys, kettles, microwaves and more can end up in landfills, leaking their harmful contents into the soil, water and air. Not only does this kill wildlife and destroy ecosystems, but the accumulation of poison can impact human health too. As heavy metals and chemicals flow into lakes and rivers, drinking water becomes polluted. These poisons spread through the soil, impacting the health of crops and animals that people also rely on.

In some western countries, e-waste isn’t hidden out of sight in landfills but is burnt in giant, open junkyards. They even ship waste electronics to other countries to deal with, and this often ends up in dumps across Africa and Asia. Workers in these places are exposed to polluted lands and chemical gas.

It is urgent that we should reduce the damaging and unsustainable side of e-waste production. Rare earth metals, some plastics and chemicals can be fed into the next generation of electronics. The steps to proper recycling of e-waste are extensive and need large investment, but more and more countries around the world are turning to e-waste recycling.
