“There's no place like home.” This English saying has much truth in it: the best place to be is surrounded by our treasured possessions and our loved ones and with a roof over our head. And for many young adults, it's the only affordable place to stay; somewhere where they can receive first-class service from mum and dad. But this comes at a price!

In some countries, it's quite traditional for people in their late teens and early 20s to live at home with their parents, but in other places, flying the nest to start their own independent life is very desirable. But there's been a growing trend, in the UK at least, for young people to return home to live—or not to leave home at all.

A survey by a price comparison website found that 18% of adult children in the UK said they were moving back home because of debt, compared with 8% last year. More young people had lost their jobs, and others couldn't afford their rent compared with the previous year. So, it's easy to see why they're increasingly becoming home birds.

Emma Craig from Money supermarket says “parents are trying to look after their children more. If your child comes home and you see them struggling to pay their bills, you feel more awkward asking them for rent or to contribute. It tugs (猛拉) on your heartstrings more.”

With parents buying new furniture and upgrading their Wi-Fi for the benefit of their children, it's easy for the returning children to put their feet up and make themselves at home. That's before they learn a home truth—that one day it might be their own kids who'll be checking into the hotel of mum and dad!

Food labels seem to provide all the information a thoughtful consumer needs, so counting calories should be simple. 【小题1】 They say how many calories a food contains, and yet what they don’t say is that how many calories you actually get out of your food depends on how highly processed it is.

Food-processing includes cooking, mixing and mashing (捣烂). 【小题2】 It can also be completed in your home when you prepare a meal. Highly processed foods are more digestible, whose effects can be big. If you eat the food raw you will tend to lose weight. If you eat the same food cooked, you will tend to gain weight. 【小题3】

As a result, when we are losing weight, we should reject processed food. And to do so would be much easier if our food labels gave us some advice about how many calories we would save by eating less-processed food. 【小题4】 The problem lies in a shortage of information. They find it hard to predict precisely how many extra calories will be gained when our food is more highly processed.

【小题5】 The first gives a precise number of calories but takes no account of the known effects of food-processing, and therefore mismeasures what our bodies are actually harvesting from the food. The second would take account of food-processing, but without any precise numbers. Faced by this difficult choice, every country has opted to ignore the effect of processing and the result is that consumers are confused.

Many youngsters in China enjoy gathering a couple of good friends and taking a relaxing walk through the streets, which is a popular form of visiting a new city, that is, Citywalk. They can follow a special urban route (路线), exploring old building, drinking a cup of coffee, or eating local snacks. It can be a special guided trip for a small group of people, or simply a relaxing walk for one or two to explore new areas, sticking to the key point: avoiding famous tourist attractions and big crowds to get a more interesting experience of the places you visit.

In China, the Citywalk trend (趋势) is spreading from big cities like Beijing and Shanghai to other cities, encouraging more people to take part. Xiao Yiyi is a young visitor from Changsha exploring new possibilities while traveling. Recently she tried six Citywalk routes to walk in different cities and posted them on her social media account, with the aim of sharing experiences to “walk in open-air museums”.

Citywalk not only offers a way for young people to interact with a city but also provides an opportunity for people who share the same interests and ideas to easily make friends. Xiao Yiyi said her group usually includes a few or so people and her trips last around half a day.

Even though Citywalk is a new trend, industry insiders say that its future possibility is huge. It is offering a beneficial change to travelers as they can better choose the experiences that suit their interests and needs. At the same time, Citywalk gives an opportunity for tour guides and travel service providers to offer a more professional service to meet ever-changing market needs.
