Global financial big dogs are no match for China's "Da Ma", or housewives, who have crowded into gold stores across China, buying up 300 tons of gold over the past two weeks. No wonder gold prices have steadied after taking a dive.

During the May Day holiday, gold stores were crowded with mostly female customers. Most of them are middle-aged "Chinese housewives". This group of buyers has risen to fame recently. They are big spenders and are desperate to get their hands on a bargain. "I bought some gold jewellery and kept them as a gift for my son when he gets married," said a buyer from Shanghai.

The gold business is skyrocketing. "Our sales are growing by the day. Yesterday we sold more than ten million yuan of gold products," a gold store salesperson said. The gold rush in China started about two weeks ago thanks to a decline in global gold prices. Media reports suggest that Chinese housewives have spent about 100 billion yuan, or about 16 billion US dollars, purchasing 300 tons of gold since mid-April. That has helped support gold prices.

"Gold prices depressed since the middle of last month but have risen gradually. That is mainly due to the strong demand from Asian markets," said foreign trader Zhang Chen from Industrial & Commercial Bank of China. "Some people even joked that Chinese housewives have beaten Wall Street analysts." For Chinese people, with limited investment options, the only thing better than buying gold is buying gold at discount prices.

Scientists in Colombia have trained a team of rats to help remove land mines from the countryside. Land mines are small bombs hidden in the ground and designed to explode(爆炸) when someone steps on them.
When trained, the rats can smell special metals in the mines and then signal(发信号) to their human team. Then why use rats for such an important job?
In the past, dogs have been used to find bombs. Rats have a good sense of smell and can respond to orders, just like dogs do. But rats are much lighter than dogs. They stand less of a chance of setting off the mines, which explode under a certain amount of weight. What’s more, the best rats are cheaper to keep than dogs. It costs about the same amount of money to take care of one dog as it does 70 rats.
The rats have already been used in Tanzania, an African country with many land mines. Luisa Fernanda Méndez and her team in Colombia are training the even lighter Wistar rats. These are the white rats with red eyes that scientists often use in laboratory experiments. “They even train their babies to perform their jobs, which saves us a lot of time, ” Méndez said.
Colombia has the second-highest rate(比率) of deaths from land mine accidents in the world. Last year, land mines killed 695 people — 56 of whom were children. A criminal group called the Revolutionary Armed Forces of Colombia, or FARC, as well as other organizations, have placed the mines. FARC are strongly against Colombia’s government. The group has placed mines all around its own bases and in many places in the countryside.
In the past, the Colombian government hired peasants and poor farmers to find mines. Many of them died trying to find the well-hidden bombs.
Colombian police official Erick Guzmán hopes the team of rats can come to the rescue(援救). “These rats will be a great help,” he said.
【小题1】How do rats help to find land mines?
