1．It's important to learn about protecting our environment.Here is a 5 R rule for us：
   Reduce
   If you want to reduce waste，you should use things wisely.A larger number of trees are cut down to make paper.If everyone uses paper carelessly，soon we will not have any trees left .Other things are also being wasted，and people don't know what to do with the waste in big cities.So it is necessary to use things wisely.
   Reuse
   You should always think of reusing the usable things before throwing them away.For example，you can give your clothes you do not wear any more to the poor.In a family，you may pass on such clothes to younger brothers or sisters.
   Recycle
   Bottles，cans and paper can easily be recycled.By recycling them we save lots of time and money.For example，Coke cans are sent to a factory，where they are smashed flat（壓平） and melted （融化） and the metal things are made for new Coke cans.
   Recover（恢復(fù)）
   When you buy a box of apples，there may be a few rotten（腐爛的） apples，you have two choices：One is to throw the whole apples away，or you can cut off the rotten parts and keep the good parts.In the way，you are recovering the eatable（能吃的） parts of food.

2．閱讀下列短文，從每題所給的A、B、C、D四個(gè)選項(xiàng)中選出最佳選項(xiàng)。
   AI，5 G，cloud computing and other digital technologies are not only changing our lives but shaping the economy as well.
   China's six major commercial banks are stepping up digital wallet efforts to provide new drive for the e-CNY （數(shù)字人民幣） trials in the country，as reported by Shanghai Securities News on March 23.
   "The functions and properties of the-CNY are exactly the same as those of the paper currency，except that the form is digital，" said Mu Changchun，head of the People's Bank of China's Digital Currency Research Institute.
   Many people are puzzled by e-CNY and electronic payments. "Digital currency has the characteristics of both paper money and electronic payment，" said Wu Qianhong，a professor at the School Electronic and Information Engineering，Beihang University."In theory，digital currency can replace paper money，Alipay and WeChat payments."
   Compared with Alipay and WeChat payments，e-CNY features anonymity （匿名性） and security.E-commerce platforms that accept payments via e-CNY will not have access to user's personal information.E-CNY users can open an anonymous digital wallet by registering a mobile phone number，and telecom operators cannot disclose （泄露） customer information to the central bank or any third-party institutions.Mu noted that e-CNY user s privacy protection is at the highest level among all the existing payment tools.
   Similar to Alipay and WeChat payments，using e-CNY requires an account.After obtaining the other party's account number，users can enter the amount of digital money to transfer （轉(zhuǎn)錢） and then enter the payment password to complete the transaction （交易）.However，the process behind these transfers are different.For electronic payments，the transfer has to go through a third party，and the receivers will get the transferred money only when they withdraw money from banks.But e-CNY transfers only need a payer and a receiver to complete a transaction.Therefore，it guarantees risk-free payments，according to Wu.
   In simple terms，e-CNY can be considered "money"，while electronic payments are like"wallets".

（1）What can we know about e-CNY？

A．It is issued by six major commercial banks.
B．It combines paper money and electronic payment.
C．It is designed to replace Alipay and WeChat payments.
D．It has exactly the same function as other payment tools.
（2）How does e-CNY protect user's privacy？

A．By limiting access to personal information.
B．By storing personal data in the central bank.
C．By opening a unique digital wallet for each user.
D．By linking telecom operators to a mobile phone number.
（3）What can be concluded from Paragraph 6？

A．E-NCY transfers require to go through a third party.
B．E-NCY and electronic payments ensure security in the same way：
C．E-NCY can be transferred without the receiver 's information.
D．E-NCY is more convenient than other electronic payments.
（4）What's the main purpose of the text？

A．To promote the use of e-NCY：
B．To inform readers of digital RMB.
C．To compare different types of payments.
D．To describe the impact of digital technologies.
