White­collar workers increasingly unhealthy

An increasing number of white­collar workers in Shanghai are getting failing grades on their physical examinations, according to a white paper on the health of white­collar workers in Shanghai.

Carried out by Shanghai Foreign Service Group, a human resources company, the report indicated that more than 53 percent of males are overweight, 46 percent suffer from a fatty liver and about 26 percent have elevated blood lipids (血脂). However，females are more often diagnosed as having breast lesions (乳房病变) that could lead to cancer (85 percent), thyroid (甲状腺) disorder (34 percent) and hemorrhoids (痔疮) (23 percent)．

Though the report also found that white­collar workers were paying increasing attention to their health — with about 84 percent saying they followed their condition closely or very closely — those with healthy lifestyles dropped to 64 percent last year from 77 percent in 2015.

The report came from about 500,000 physical exams taken by white­collar workers in Shanghai over the past five years. “I always eat and drink too much and never exercise，” said Wei Ruoxi, a 26­year­old working in finance who is struggling with being overweight. “I know what a healthy lifestyle looks like, but the job just brings too much pressure and squeezes out exercise time，” she added. Hu Xiaolong, 30, an accountant in Shanghai, said he was determined to live healthily from now on. “My recent physical examination shows a little shadow in the lung, which startled me when I heard it. I really need to quit bad habits like smoking and staying up late.”

The white paper also showed that more people are turning to commercial health insurance to cope with financial risks caused by health problems. The popularity of insurance purchases among the participants reached 15.3 percent last year, a rise of 4 percentage points  in just one year. Most participants also expected their companies to help them with effective health management, such as offering membership cards for gyms, flexible working schedules and regular physical examinations.

If you have always wanted to grow plants but don't have a_green_thumb,_the Parrot Pot is just the right thing for you. It's a smart pot that grows plants itself, keeping them alive no matter how badly you mess up.

Priced at $99, the Parrot Pot has several kinds of sensors (感应器) that measure light, temperature and the level of fertilizer, making sure that the plant always gets what it needs. If it finds that more light, water or fertilizer is  required, it will send the user a warning message through a smartphone app (应用程序) called Flower Power. What's more, it can actually water your plants using a tank filled with water.

The battery­powered pot is equipped to handle extreme water shortages. Whether you are travelling or you forget to water your plants, they'll still survive. It can hold over two liters of water, enough for most plants to survive a week. It can also switch to water­saving mode (模式), in which the plants are kept alive for three to four weeks without being watered.

“Equipped with various kinds of sensors, the pot knows

 exactly how to attend the plant. If it needs water, the pot will water the plant by itself. It runs on four AA batteries and it runs for almost a year，” said Parrot Pot designer Vincent Bihler. The pot is an improvement over Flower Power, a device that can be connected to any pot to get similar updates.

Parrot, a Paris­based company, will release (发行) the Parrot Pot globally in December, along with the Flower Power app. It will come loaded with a variety of 7,000 supported plants to choose from. Interested?

本文是一篇说明文。文章主要介绍一款名为Parrot Pot的智能花盆，该花盆可以帮助你很好地照顾你的植物。

答案：C
