    T:Different peple have different ideas. Maybe in yur daily life, yu haven’t taken the things seriusly. Are yur ideas really green? Nw let’s read a passage related t the tpic t check the answers.
    Step 2:Read fr main infrmatin
    Read the fur subheadings in the passage and decide if they are true r false.
    Subheading 1:Paper shpping bags are better than plastic nes.( )

    Suggestin:The key is t keep yur shwer time as shrt as pssible.
    Task 2:Summarize the passage and pay attentin t the sentences f “really green living”
    Mst f us are 1 (awareness) that we must take care f the envirnment,and the majrity f us take steps 2 (save) energy and reduce waste and pllutin.But in fact,sme lng-held cmmn sense turns ut nly half true,r even 3 (cmplete) false.Fr example,peple think paper bags are 4 (gd) than plastic bags as they are easier t break dwn than the plastic 5 (ne).The prcess f making paper bags, 6 ,is mre energy cnsuming and water wasting.S,take a reusable bag with yu when shpping.Besides,remve the plug frm its pwer supply, 7 the stand-by mde still use pwer.Eating lcal fd isn’t necessarily gd fr the envirnment,even taking transprtatin 8 accunt.Sme take it fr granted 9 a shwer cnsumes less water than a bath.But that depends 10 hw lng yu spend in a shwer.The best plicy is t keep yur shwer as shrt as pssible.
