2．We usually think that garbage （垃圾） is useless and dirty.However，an art exhibition in 2019 proves that "useless" things can actually be helpful.
   Dear Pretty Rubbish，an art event organized by the World Wide Fund for Nature （WWFN） and digital media art company Blackbow，was held in Beijing.It looked at wasteful consumption （消耗） and asked questions about the relationship between our lifestyles and our garbage.
   "We hope that everyone who visited the show can think about how 'useless things' are produced，why they are tossed out，and whether 'useless things' are really useless，" said Cao Yujia，the design director at Blackbow.
   The organizers said that all the raw materials for the exhibition were collected from community garbage cans （金屬罐）.
   Artists Zhou Yuxuan and Liu Yifan collected nylon cable ties （尼龍?jiān)鷰В?，LED lights and beverage bottles from designers' workshops to create a work where plastics，in the shape of cells，"grow"in a corner.There，the lights blink （閃爍） regularly to imitate （模仿） "breathing".When people walk near it，the work responds by forming light patterns，as if communicating with the visitors.
   Speaking about the work，Zhou said： "It's like some kind of communication between humans and plastics."
   Plastic has a life longer than almost any creature （生物），taking centuries to break down.Though people blame plastics for damage （破壞） to the environment，they are a big part of our daily lives.
   "So we want to ask the question：Although the damage continues，is there a way for humans to reconcile （和解） with plastics？" said Zhou.

（1）What is the purpose of "Dear Pretty Rubbish"？

A．To show how to break down plastic products effectively.
B．To show how to recycle different types of useless things around home.

C．Ways to turn useless things into different shapes.
D．Communication between artists and visitors at the exhibition.
（3）Which phrase can take the place of the underlined phrase "tossed out"？

.
A．Worked out
B．Used up
C．Thrown away
D．Put off
（4）Which of the following might Zhou agree with？

A．Useless things are really useless.
B．Artists should make works from garbage.
C．Plastics should be left to break down on their own.
D．Humans should find a better way to live with plastics.

3．Tabata training is a very popular way of exercising these days.It doesn't take much time or space，and it burns calories faster than other ways of exercising.The idea of Tabata training is simple：exercise for 20 seconds，rest for 10 seconds，and then repeat （at least eight times）.The moves for the 20-second exercise are not difficult to learn.Jumping jacks，high knees，squats，and planks are some of the most common moves.You can decide yourself what moves to do in your Tabata training.For example，you can do more leg exercises if you want strong legs.

One great thing about Tabata training is that your body will keep burning calories for at least an hour after 4 minutes of Tabata training.But to have this wonderful "afterburn"，you need to exercise really hard during each 20 seconds.If you seldom exercise or have heart problems，this exercise may not be good for you.But for people who enjoy exercising but are too busy to go to the gym，Tabata training might just be the answer.
