Iodine (碘）– rich salt was the hottest item on Chinese shelves Thursday, being snapped up (抢购) by shoppers after rumors spread that iodine intake could help protect one’s body from radiation damage, although the authorities have confirmed that the nuclear crisis in Japan had not affected China.
Rumors also spread about radioactive substances being leaked into ocean water that could pollute Chinese coasts.
The crazy buying has occurred nationwide, from the supposedly easily – harmed eastern coastal provinces to regions far – inland such as Xinjiang.
Supermarkets and convenience stores began reporting the lack of salt stocks from early Wednesday, with all salt sold out at many Carrefour and Wal – Mart stores. Some online clothes stores have begun offering salt as a bonus to customers.
Relevant government departments were trying hard to stop this round of panic – buying.
The Ministry of Health deniedthe rumor that eating more iodine – rich salt could repair damage from radiation, saying that it is technically impossible to absorb enough iodine for radiation prevention from eating salt.
The government urges the local market authorities to keep all salt sellers in check and to prevent storing and overpricing.
Also the spokesman of the government said that China’s seawater, as a source of salt, would not be affected by the nuclear crisis, as it would be impossible for radioactive substances to reach Chinese waters via the eastward ocean current.
“Reasons behind the salt rush include unclear information on the development of the nuclear crisis and terrifying media reports of the severity of a possible complete meltdown. If the fear of a Chernobyl – like catastrophe cannot be ended, the crazy buying will likely continue,” said a professor from Beijing University.
Beijing urged Tokyo Thursday to better release information at the Fukushima plant.

A．The rumor caused by the unclear information.

【小题2】Some online clothes stores began offering salt as a bonus to customers because _______.
A．they can increase their sales by doing so B．the salt from them is more effective
C．the customers prefer to buy salt on line D

h salt is to _______.

A．increase the sales of related products	B．raise the price of products online

【小题4】Why is it impossible for radi

oactive substances to reach Chinese waters?

Algae(水藻) are very simple plants. They grow in fresh water or salty water. Seaweed is algae that grow in salty water. Seaweed is red or brown in color. The Japanese people use these plants from the sea in many ways. From it, they make a food called Kombu. Kombu is seaweed that has been dried, cooked and pressed together. Then it is dried again and cut into long pieces. The Japanese eat a lot of Kombu and like it very much.

Japanese farmers often use seaweed as fertilizer. It makes their plants grow better. Many farmers also find seaweed makes a fine food for their animals.

From seaweed the Japanese also get iodine(碘), which they sell to other countries. Iodine is used in many ways all over the world. It is used in making medicine. It is added to the salt we use at the table. Scientists even use one form of iodine to “ seed clouds” when they want rain to fall.

Kombu is a kind of ____ according to the text.

A. plant B. medicine C. food D. fertilizer

In the last sentence of the text, “seed clouds” means ____.

clouds spreading like seeds

the seeds like clouds

to make rain fall with human power

dropping seeds by clouds

The main idea of the story is that ____.

The Japanese eat seaweed when they want rain to fall.

Kombu is made into medicine for farmers.

The Japanese use seaweed in many ways.

The Japanese eat a lot of Kombu.

Sample inspections conducted on Tuesday found low levels of radioactive iodine in spinach( a kind of green vegetables) planted in Beijing, Tianjin and Henan province --- about 1-3 becquerels per kilogram (Bq/kg), the statement said.

"The contamination level detected is too low to be harmful to public health," it said.

According to health experts, radioactive iodine can accumulate in humans once ingested in high concentrations and increases the risk of thyroid cancer. But it decays naturally within weeks.

Leafy vegetables grown in the open like spinach, lettuce and leek are among the first foods to be tainted by radioactive deposits.

Raw milk is also susceptible to radioactive contamination as livestock feed on grass.

Tests carried out in March showed spinach and milk taken from farms near Japan's nuclear-stricken area had exceeded(go beyond) government-set safety limits for radiation.

No cases of tainted water or milk have been reported in China but the ministry vowed to further strengthen monitoring.

Wang Zhongwen, a researcher at the China Institute of Atomic Energy's radiation safety department, told China Daily on Wednesday that currently China only had the means to conduct food radiation tests in a few regions.

The statement also said that recent rain in Beijing and Tianjin meant radioactive substances could have fallen on vegetables.

Chen Jicang, a vegetable dealer in Beijing, said on Wednesday that concerns are growing among consumers, businesses and governments across the world.

"We have yet to see any impact on our business from the radiation, but we will keep a close eye on how the issue develops," he said.

He added that most vegetables consumed in Beijing are produced locally, and he might switch to other varieties if spinach sales suffer.

Yang Guoshan, a researcher of radiation medical science at the Academy of Military Medical Sciences, said people could safely eat products that contain low levels of Iodine-131.

"The radiation level is so low that residents don't need to spend any extra effort on cleaning them," he said.

Gao Jie, a 52-year-old resident in Tianjin said she is deeply worried because spinach is a staple part of her family's diet.

"If spinach is radioactive, is there any possibility that other types of vegetables are safe?"

Trace levels of radioactive isotope cesium-137 and -134 were detected in the air in 21 provinces and regions on Wednesday, up from 17 on Tuesday, according to China's National Nuclear Emergency Coordination Committee.

What does the underlined word mean in para 1?

A. protected B. contained C. polluted by dangerous substances D. tested

Why are the spinach and milk taken from nuclear-stricken area not safe?

A. Because tests have been carried out there.

B. Raw milk is sensitive to radioactive contamination as livestock（家畜）feed on grass.

C. The amount of radioactive substances goes beyond the safe limits for radiation.

D. Japan is a nuclear-stricken area.

Where do you think this passage comes from?

A. a magazine B. CCTV news C. a journal D. a novel

What is not mentioned in the passage?

A. Consumers became concerned about the safety of vegetables.

What do you think is mainly talked about in the passage?

A. How the radioactivity came into being

B. What we should do in face of radioactivity.

C. Radioactivity has no side effect on human being.

D. Home-grown food has been affected by radioactivity.

It is the first report that home-grown food has been contaminated by radioactivity, largely Iodine(碘)-131, since the ministry ordered radiation( powerful and harmful rays that are sent out from radioactive substances) tests on food and water at the end of March in 14 mainland regions including Beijing, Tianjin, and some coastal provinces.
