Watching a 3D movie can more than double the concentration powers and cognitive(认知) processing of children, a new research claims.
A study made by visual technology firm RealD and led by child psychologist Dr Richard Woolfson suggests that children aged between 7 and 14 experienced twice the cognitive processing speed and performed better in testing after watching 20 minutes of a 3D film. This is despite suggestions that attention spans(时期) in children have shortened in the last decade due to unlimited to access to entertainment, including on-demand TV, gaming and social media. A 2015 study claimed that watching 3D content had a similar effect to brain-training exercises.
Consumer psychologist Mr Fagan said that the increased stimulation(刺激) found in watching something in 3D "exercised" the brain and improved performance in the short term. "3D films can play the role of ‘brain-training’ games and help to make children ‘smarter’ in the short term," he said. "The shortening of response times after watching 3D was almost three times as big as that gained from watching 2D; in other words, 3D helps children process aspects of their environment more quickly. This is likely to be because 3D is a mentally stimulating experience which ‘gets the brain's juices flowing’."
The experiment saw children given a range of cognitive tests before watching 20 minutes of a movie in either 2D or 3D and being tested again. The results showed those who saw the 3D content reacted faster and performed bettering the second round of testing. Mental engagement also rose by 13% among 3D watchers. Child psychologist Dr Woolfson added that “supportive parenting” and regularly listening to classical music can also aid a child’s memory.

How did the ancient Chinese keep food warm in winter?
Facilities like electric rice cookers, microwaves, and electric kettles, make it easy for people to keep food warm and enjoy a comfortable winter. So how did Chinese people in ancient times keep food warm in winter without these? In fact, ancient Chinese people used their own methods of heat preservation as early as the Shang and Zhou dynasties.
● “Wen Ding”, ancient rice cooker
One of the major functions of an electric rice cooker is to keep food warm. The “Wen Ding”, an ancient cooking container, served the same purpose, but instead of using electric energy, the ancient cooking container, served the same purpose, but instead of using electric energy, the ancient cooking container preserved heart by burning fuels like charcoal.
The “Wen Ding” unearthed in Nanjing in 1989 is thought to be the oldest of its kind discovered in China, dating back to the Stone Age, The craftsmanship of making the “Wen Ding” was developed in the Bronze Age. The bronze Ding from Shang and Zhou dynasties took on different shapes and structures.
● “Ran LU”, ancient small hot pot
The “Ran LU” is a small size cooking vessel(器皿) made of bronze, which can be divided into three parts. A charcoal stove forms the main structure, with a bottom tray to hold charcoal ashes, and a movable cup at the top. Some experts have concluded that the vessel’s structure suggests it may have been used as a small hot pot and that these vessels became popular in the Warring States Period(475—221 BC)
●Bronze You, ancient kettle
The Bronze You was one of the most common wine containers during the Shang and Zhou dynasties. The Bronze You can also be used to warm wine. For example, the Bronze You with beast mask design, unearthed in Jiangxi province, has an opening where charcoals could be placed. Just as people today can’t do without an electric kettle, the Bronze You allowed people to enjoy a hot drink.
●Bronze Yan, ancient steamer
Although the “Wen Ding” was effective at keeping food warm, the ancient Chinese people later found that its burning produced pollution. As a result, the Bronze Yan was made with a two-tier structure and used to steam rice and other grains. After the Eastern Han Dynasty (AD 25-AD 220), further improvements to the Bronze Yan led to the modern-day steamer.
1.When did the “Ran LU” become popular?
A. In the Zhou Dynasty.
B. In the Warring States Period.
C. In the Eastern Han dynasty.
D. In the Stone Age.
2.The Bronze You, unearthed in Jiangxi province, has an opening to ________.

C. place charcoalsD. hold charcoal ashes
3.What is the unique advantage of the Bronze Yan?
A. It is warm.
B. It is convenient.
C. It is environment-friendly.
D. It is useful.
4.Among the following products, which one may have the longest history?
A. The “Wen Ding”.B. The “Ren LU”.
C. The Bronze You.D. The Bronze Yan.

I can’t swim so I have a strong fear of water. Look back at my childhood, I think that three reasons might explain fear. Firstly, I am not allowed to go near the water when I was a child, as my mother had an unreasonable fear of it. Therefore, I was taught to see to the water as something danger. Secondly, my eyes became bad when I was five. If I took off my glass in the water, I couldn’t see something, and this increased my fear. What’s worse, for a child I once saw a neighbor drowned. Since then I have been more frightening.
