高二英语单项填空简单题查看答案及解析

The Internet is a growing new world that has been developing ever since it was created many years ago. The only reason Internet sales are not taxed (征税) is because we did not know the Internet would be used to sell products when it was created. Internet sales are no different than going into the store to buy the exact same product except for the fact that Internet sales are not taxed.

When buying online, people cannot see and touch the product the same way they could in a store. To fix this, customers are going into the store to see the product. Then if they like the product, they buy it online to save money on the sales tax. This is a form of tax evasion (逃税) if you ask me!

Everyone has to pay the tax in the store so they should have to pay taxes online as well. Also, the added money brought in through Internet taxing could help the government to fund (为……拨款) certain policies and other things that they could not do without the added funds. This could go toward the country’s schools or other things necessary for society to function well. These funds could be extremely beneficial because of the recession (经济衰退) that the country is in at this point. Internet taxing is a way to increase those funds and in turn improve the quality of life for all who live in that country.

In conclusion, there are many more positives than negatives in the argument over taxing Internet sales. I do understand that I may have to pay more if I want to buy something online, but the funds stay within my society and help my country. The added cost may hurt me at first but in the end, the funds will help me and others in our country.

1.The text mainly discusses _____.

A.whether it is a good way to buy things online.

B.whether Internet sales should be taxed.

C.why people love to buy things online.

D.why Internet sales are not taxed.

2.Internet sales are not taxed because _____.

A.selling online was unexpected. B.they are different from store sales.

C.people don’t know how to tax them. D.many people are against taxing them.

3.What can we learn from Paragraph 2?

A.Online shoppers find it difficult to buy satisfactory goods.

B.Customers get better products at a lower price online.

C.Problems related to online shopping are hard to fix.

D.Online shoppers probably try to avoid paying tax.

4.According to the author, taxing Internet sales _____.

A.is good for all people. B.can help the country out of the recession.

C.can help improve the quality of products. D.is beneficial to the development of Internet.
