计算题：新华有限责任公司（以下简称新华公司），以人民币作为记账本位币，外币业务采用业务发生时的即期汇率折算，按季度计算汇兑损益并提供季度财务报表。新华公司2012年第一季度发生的相关外币业务如下：

（1）1月1日与外商签订投资合同，外商分两次投入外币资本，投资合同约定的汇率为1欧元=9.2元人民币。1月10日，新华公司收到外商的第一次投资，投资金额为300万欧元，当日的即期汇率为1欧元=9.3元人民币；2月1日，收到外商的第二次投资，投资金额为200万欧元，当日即期汇率为1欧元=9.35元人民币。

（2）1月15日以每股5欧元的价格购入A公司500万股普通股，当日即期汇率为1欧元=9.3元人民币，新华公司将该资产划分为可供出售金融资产，款项已经支付。2012年3月31日该可供出售金融资产的市价变为每股6.5欧元。

（3）2月1日以每股2欧元的价格购入B公司10万股普通股作为交易性金融资产，当日即期汇率为1欧元=9.35元人民币，款项已经支付。由于市场价格变动，3月31日该股票的市价变为每股1.5欧元。

（4）新华公司2月5日从C公司购入国内市场上尚无的M产品1000件，每件价格为0.5万欧元，当日即期汇率为1欧元=9.4元人民币。3月31日，尚有100件M产品未销售出去，国内市场仍无M产品供应。M产品的市场价格降至0.35万欧元。

（5）假设新华公司2011年12月31日银行存款欧元户的账面余额为5000万欧元，当日的即期汇率为1欧元=9.2元人民币，不存在其他外币账户余额。2012年3月31日的即期汇率为1欧元=9.45元人民币。

要求：

（1）根据上述资料，不考虑其他因素的影响，对上述事项（1）至事项（4）做出相应的会计处理，编制会计分录（不要求做外币银行存款汇兑差额的处理）。

（2）综合计算外币银行存款季度末产生的汇兑差额，并编制会计分录。

     Growing up in Philadelphia, Lieberman started cooking with his stay-at-home dad when he was

seven. His food-loving family had two kitchens, and he quickly learned what was the best way to bake

his cakes. Lieberman improved his kitchen skills greatly during a year abroad before college, learning

from a cook in Italy and studying local specialties(地方特色菜)in Germany, Spain and France. At Yale,

he was known for throwing dinner parties, single-handedly frying and baking while mixing drinks for

dozens of friends. Just for fun, he and some friends decided to tape a show named Campus Cuisine

about his cooking. Lieberman was a real college student showing his classmates how to do things like

making drinks out of dining-hall fruit. That helped the show become very popular among the students.

They would stop Lieberman after classes to ask for his advice on cooking. Tapes of the show were

passed around, with which his name went beyond the school and finally to the Food Network.

     Food Network producer Flay hopes the young cook will find a place on the network television. He

says Lieberman's charisma is key. "Food TV isn't about food anymore," says Flay. "It's about your

personality and finding a way to keep people's eyeballs on your show."

     But Lieberman isn't putting all his eggs in one basket. After taping the first season of the new show,

Lieberman was back in his own small kitchen preparing sandwiches. An airline company was looking

for some one to come up with a tasteful, inexpensive and easy-to-make menu to serve on its flights,

Lieberman got the job.
