第1题：
The above chart shows individual income tax in China. The tax free threshold is 3,500 RMB per month. The tax rates are divided into 7 brackets. The lowest rate is 3% for income between 3,501 and 5,000, while the highest rate is 45% for income over 80,000. Therefore, the higher our income is, the more tax we should pay. Tax, which can be used in public services such as education, road construction, public health and so on, is very important to our country. As we all know, tax makes up a great part of our country’s revenue, and the development of our country depends on it. From what has been discussed above, we can see that it is everyone’s legal duty to pay tax because taxes contribute to the country and create benefits for everyone. Those who try to evade taxation are sure to be punished. In short, paying tax is our responsibility to society.Decide if each of the following statements is TRUE (T) or FALSE (F).
1. The purpose of the passage is to help people know the tips how to pay less tax.()

第14题：
听力原文： If you want to invest money at short term, you've got several possibilities: first, a current account. This gives you the possibility of having all your money at your immediate disposal. It also entitles you to a cheque-book. Second, you've got a deposit account, which usually pays about 3. 5% interest, less tax. In that respect, a deposit account's a better investment than a current account. However, though you are entitled to a cheque-book, you can only withdraw up to a certain sum each month. For large amounts, you must give the bank a few months' notice. Finally, you have certificates of deposit. These pay in the order of 6.5% interest.
28. How many possibilities are there for a customer to invest money at short term?
