英语自学网

China's Ministry of Finance (MOF，中国财务部，这个英语翻译要注意下，根据我国政务体系习惯称为财务部，但同一英文表达，对于日本应译为“财务省”) said Wednesday that it will float（发放，一般用于债券、股票等，还有一替换词为issue，也指“发行，发放”） 30 billion yuan (4.61 billion U.S. dollars) worth of book-entry treasury bonds（记账式国债，BEC同学可以直接背这个词） starting Thursday.
The bonds（通指债券） will carry a mature term （国债的期限）of 20 years with a fixed annual interest rate（固定年利率） of 4.15 percent, according to a statement posted on the MOF's website.
The bonds will be sold to the public from April 28 to May 3 and become tradable（可交易的，可买卖的） on securities markets （证券市场，注意securities，必须用复数才是“证券”的意思）on May 5, said the statement.
The interest of the bonds will be paid on a half-year basis（利息按半年支付）, the statement said.
The issuance marks the ministry's tenth batch（一批） of book-entry treasury bonds （国债）this year.
