The Chinese government started the strictest rules of plastic products on January 1, 2021.If you're a drink lover, it means you'll have to say goodbye to plastic straws(吸管).
The following are the advantages and disadvantages of three environmentally friendly choices that can take the place of plastic straws.Can they be just as good？
Metal straw
Advantage: It can be reused.Once you finish your drink, you can clean it with a little brush.
Disadvantage: If you're drinking something very hot, it could burn your lips.
Glass straw
Advantages: It's also reusable, but unlike a metal straw, it doesn't heat up so easily.Plus, you get to see what you're drinking, which is a big part of the milk tea experience.①
Disadvantage: It can be easily broken.If you leave it in your bag and accidentally break it, it might be harmful to your valuables.
Paper straw
Advantage: It's not plastic.
Disadvantage: After 15 minutes in water, it becomes so soft that it's almost unusable anymore.Better finish up your milk tea fast！②
By 2025, the end of China's 14th Five Year Plan period, the country aims to control plastic pollution.These early inventions might look imperfect, but there must be better solutions in the future.In the latest five year plan, the Ministry of Ecology and Environment is expected to put all these green inventions to good use.
(　　)1.Nowadays, you can't use ________ to drink your milk tea.
A.plastic straws B.mental straws
C.glass straws D.paper straws
A
(　　)2.Glass straws have the following advantages EXCEPT ________.
A.they are reusable
B.they won't burn your lips
C.they enable you to see what you're drinking

D
(　　)3.Which is the disadvantage of paper straws
A.They are expensive.
B.They can pollute the environment.
C.They are unable to use after 15 minutes in water.
D.They can be eaten before you finish your drink.
C
(　　)4.We can learn from the last paragraph that ________.
A.2025 is the end of China's 15th Five Year Plan period
B.the plastic pollution has already been under control
C.the straws mentioned in the passage are perfect
D.all the green inventions will be used in five years

解题技巧点拨
1.应用文相对简单，先看问题，再有目的地读文章。
2.看问题时要找出问题的关键词。如第2题，题目关键词是glass straws和advantages except，也就是要找glass straws的不足，快速定位到文章Glass straw的Disadvantage部分：It can be easily broken，故选D。
3.对于we can learn from … 或是which of the following is true这类找正确选项的题目，有时可以使用排除法。如第4题，结合最后一段依次核对每个选项的正误。A项：2025 is the end of China's 15th Five Year Plan period与原文By 2025, the end of China's 14th不符，故A项错误。B项：the plastic pollution has already been under control与原文By 2025 … aims to … 意思有差别，一个是已经控制，一个是将要控制，故B项错误。
C项：the straws mentioned in the passage are perfect与原文These early inventions might look imperfect意思相反，故C项错误。故选D。
4.结合第4题可以发现，阅读理解的错误选项经常会把文中不同内容进行嫁接，或者篡改文中内容的一部分，放大或缩小文中提到的内容范围，断章取义。
重点词汇、短语积累
1.say goodbye to与……说再见　
2.valuable n.贵重物品　
3.aim to do sth.力争做某事
4.put sth.to good use有效利用
好句仿写
1.You get to see what you're drinking, which is a big part of the milk tea experience.
要点：which引导非限制性定语从句。定语从句分限制性定语从句和非限制性定语从句。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开。
仿写：莉莉获知她已经通过了数学考试，这使她终于放心了。
______________________________________________________________________________________________
Lily got to know that she passed the math test, which set her heart at rest at last.
2.Better finish up your milk tea fast!
要点：Better do…！祈使句前加better, 表示“最好做某事”。
仿写：最好每天都喝一杯牛奶。
______________________________________________
______________________________________________
Better drink a glass of milk every day!
