Q: WASHINGTON, March 14 (Xinhua) --U.S. President Barack Obama confirmed on Saturday at the White House that China can have confidence in the American economy.

"Not just the Chinese government, but every investor can have absolute confidence in the _ of investments in the United States," Obama said.

"There is a reason why even in the midst of this economic downfall you have seen actual increases in investment flows here in the U. S.,"he said.

Obama also noted the U. S. will push for stricter regulation of the financial industry "front and center" at the upcoming Group of 20Summit in London ,ending an argument between the Europe and the United States over whether more focus should be placed on financial regulatory reform.

Chinese Premier Wen Jiabao said earlier Friady he is "a little bit worried "about the safety of Chineseassets in the United States ,urging the U. S. government to ensure the security of those assets.

China has invested its hugeforeign exchangereserves in low-risk but low-yield assets ,such as U. S.government bonds ,to play it safe . According to the U.S. Treasury, China held 681.9 billion U.S. dollars worth of U.S. government bonds as of November.

"China is indeed the largest creditor of the United States, which is the world' s biggest economy .We are extremely interested in developments in the U. S. economy."said Wen, adding that he is expecting the effect of the measures taken by the U.S.government to counter the global financial crisis.

Asked to react to Wen' s concern, Lawrence Summers, director of the U.S. National Economic Council, noted on Friday that the U.S. will be soundsteward of the money it invests.

Q: Although there is some evidence of earlier inhabitation in the region of Utrecht, dating back to the Stone Age (app. 2200 BCE) and settling in the Bronze Age (app. 1800800 BCE), the founding date of the city is usually related to the construction of a Roman fortification (castellum), probably built in around 50 CE. A series of such fortresses was built after the Roman emperor Claudius decided the empire should not expand north. To consolidate the border the limes Germanicus defense line was constructed along the main branch of the river Rhine, which at that time flowed through a more northern bed compared to today (what is now the Kromme Rijn). These fortresses were designed to house a cohort of about 500 Roman soldiers. Near the fort settlements would grow housing artisans, traders and soldiers' wives and children.

From the middle of the 3rd century Germanic tribes regularly invaded the Roman territories. Around 275 the Romans could no longer maintain the northern border and Utrecht was abandoned. Little is known about the next period 270650. Utrecht is first spoken of again several centuries after the Romans left. Under the influence of the growing realms of the Franks, during Dagobert I's reign in the 7th century, a church was built within the walls of the Roman fortress. In ongoing border conflicts with the Frisians this first church was destroyed.

Q: Did you sleep the day away on March 21? Well, you should have done that because it was World Sleeping Day. This is the one day of the year when people around the world care about their sleep and ask themselves a lot of questions about sleep. Why do we need sleep? Nobody as yet can give a correct answer to this question. However, tests have shown that lack of sleep over about four weeks leads to a strong drop in body temperature, great weight loss and finally sickness. Different people need different amounts of sleep. Eight hours a night is considered the average amount of sleep. For teenagers the least number of sleeping hours advised by doctors are ten hours for primary school students, nine for junior highs and eight for senior highs. Some people seem to get along just fine with very little sleep at night. Leading American scientist Thomas Edison said that sleep was a waste of time. He did, however, take naps during the day. On the other hand, Albert Einstein, another great scientist, said he needed at least ten hours' sleep a night. Here are some of the most useful suggestions, for a good night's sleep. Go to bed regularly. Use your bed only to sleep. Don't exercise in the evening. Keep the bedroom dark and quiet. Drink a glass of milk before sleep.
