Nne f them is wrng. China is impressing the wrld peple with its advanced technlgy.
3.Presentatin
Sme students are vicing their pinins abut the nging Wrld Cup. Pay attentin t the bld wrds.
He culd be ill because he turned pale(Bb).
Five-time winners Brazil must be favrites t lift the Wrld Cup trphy in Qatar. (Lucy).
This team might nt win in the grup stage if they dn’t change their strategy. (Mark)
Nw, answer these questins.
What d the wrds in bld indicate: an rder, a request, ability, r a pssibility?
Will the meaning f sentence (a) change if we replace “culd” with “must” r “might?”
Bld wrds indicates a pssibility. Must dn’t state the fact. Lucy is predicting wh the winner is. Bb and Mark are bth stating the pssibility f an event.
Which mdal verb describes the largest pssibility and the smallest pssibility? “Must” shws that yu think smething is quite true. Use “might” r “culd” t shw that smething is pssibly true. We can replace “culd” with “might” instead f “must”.
D yu remember the relatin between “may” and “might”, “Might” is mre tactful in tne and has the smaller pssibility than “may”.
4.Practice
练习1：Nw rewrite the underlined sentences in the cnversatin using must/may/might/culd. (书上)
“I expect yu are feeling tired nw.” We can rewrite “Yu must be feeling tired nw”. Because Chris stayed up late t make preparatins fr this party.
Jean said. “It’s pssibly him.” Therefre, we can rewrite “It may/might/culd be him.” “I’m sure that’s Lucy”. She is very sure and cnfident. It can turn int “That must be Lucy”. The last ne, “Oh, they’re waving at us! Maybe they’re frm ur schl.” We can say “They may/ might/culd be frm ur schl.”
练习2：Fill in the blanks with “must” “culd” “might”
It must be raining, fr all walkers are carrying umbrellas.
Wearing a N95 mask culd/might reduce the risk f infecting nvel crnavirus.
He is away frm the schl. He culd/might be sick.
Jhn, yu must nt play with the knife, yu culd hurt yurself.
These are answers. It’s very easy, right? We need t fcus n whether smene is sure abut this thing. And hw much he is sure.
5.Prductin
Nw, let’s play a game. I will give yu sme clues abut a figure. And yu must answer with a cmplete sentence. “It must/culd/might/can’t be… because he…” Nw yu are divided int fur grups. The grup guessing the mst figures is the winner. Here we g.
The first persn—Zhng Nanshan
T: This persn can sing, dance, and play basketball. (He culd be an actr called Bai Jingting because he masters all these skills.)
T: This persn is 84 and still des high-strength physical exercise every week. (He might be an ld actr called Chen Daming.) (Yu must be wrng because Chen Daming is 65.)
