What is the main tpic abut their interview?
While-listening
Read the statements belw and decide which statement is crrect. Listen t the tape again and try t figure ut Prfessr Keeling’s attitude. 1. We shuld stp depending n fssil fuels fr ur energy.2. 90% f ur energy cmes frm fssil fuels. 3. We can replace fssil fuels with cleaner surces f energy.4. Nuclear pwer is a gd surce f energy.
L: Prfessr Keeling, I’ve read that we must stp using fssil fuels if we want t reduce the amunt f carbn dixide in the air. K: Yes, that’s right, Li Bin. Hwever, it’s difficult. Our mdern industrial scieties depend n the energy we get frm fssil fuels. It’s a very cheap and cncentrated frm f energy. L: Is it true that 90% f the wrld’s energy cmes frm fssil fuels?
K: Yes, that’s crrect. And there’s enugh t last fr centuries. L: Culd we replace fssil fuels with cleaner surces f energy like sun r wind pwer?K: I’m afraid nt. We just can’t prduce enugh. Yu need huge areas f land t prduce enugh wind energy. The technlgy we have at present cannt prvide enugh sun energy.
L: S what abut nuclear pwer? That desn't prduce carbn dixide. K: True, but it’s very dangerus. Remember the accident at Chernbyl. Peple are still dying f the radiatin that was prduced by that disaster!
1. We shuld stp depending n fssil fuels fr ur energy.2. 90% f ur energy cmes frm fssil fuels. 3. We can replace fssil fuels with cleaner surces f energy. 4. Nuclear pwer is a gd surce f energy.
Let's Put it Tgether
Prfessr Keeling thught we shuld abandn the usage f fssil fuels, but it was difficult because the industrial scieties depended s much n it. 90% f ur energy cmes frm fssil fuels. S human beings at present can nt replace it with anther surce f energy, like nuclear pwer which is very dangerus nw.
Can yu think abut sme ways t save energy at present?
1. Use fewer mtr vehicles2. Try t accept electric cars3. Use renewable energy
L: S what can we d?K: Well, there are _____ things. First, we must find ways f using fssil that wn’t put ___________ int the air. Secnd, we must prduce _______ that are ecnmical with energy. Third, we must ask peple t ________ n the energy they use.
Listen t Part 2 and fill in the Blanks.
L: But that’s n a _______ level. What abut _______ ? They dn't cut dwn n their use f ______.K: N, they dn’t. Hwever, that is a ______ we must wrk n as a ____ cmmunity. That means ______ and develping cuntries will have t wrk tgether. L: But it’s nt the develping cuntries that put mst f the carbn dixide int the air. The develped cuntries are really the nes t ____ .
K: That's true. S we must wrk tgether because glbal warming will _______ everyne. If we want the future ____________ t have a gd life, we must all the planet.
Hw many parts did Prfessr mentin? What are they?
Tw parts1. persnal level2. cuntry level
Listen again and try yur best t write dwn the detailed suggestins
Persnal level
1. Use fssil fuels withut CO22. Prduce prducts that are ecnmical with energy3. Cut dwn n the energy we use
Cuntry level
Develping and develped cuntry wrk tgether.Cut dwn the emissin CO2
Cnclude Prfessr Keeling's Suggestins n Saving Energy
Prfessr Keeling put frward that, frm the individual level, we can d three things t save energy. Finding ways t use fssil fuels that d nt put carbn dixide int the air, prducing prducts that are ecnmical with energy and cutting dwn n the energy we use everyday are three main methds fr each persn t d.
On the wrld's level, Prfessr Keeling strngly suggested that all the wrld shuld wrk tgether including develping and develped cuntries and try t cut dwn the use f energy. Althugh develping cuntries dn't put mst carbn dixide int the air, the glbal warming will affect everyne n earth.
Expressins f Agreement and Disagreement
Exactly.That's true.Yu're right.That's right.That's crrect.I agree.
I'm afraid I disagree with yu.I'm afraid nt.N, I dn't agree.I dn't think s.N way.I dubt...
Listen t the Tape Again
Try t appreciate the agreement and disagreement between Prfessr Keeling and Li Bin.
Pst-listening
Try t make up an interview abut Hw t save energy with the mayr f yur city.Yu shuld use at least tw expressins f agreement and disagreement.
S: Dear Mr. Chen, I've heard that ur city is putting great effrt in saving energy.M: That's crrect. T reduce the release f carbn dixide, we have put frward a lt f ways. Fr example, all the buses in Beijing have been replaced by cars pwered by electricity instead f fssil fuels. S: Is it true that we are ging t abandn the cars pwered by fssil fuels?
M: I'm afraid nt. Gasline vehicles are mre cnvenient and efficient fr citizens in Beijing. S: As an internatinal city, d we need t clse all the factries in Beijing?M: I am afraid I disagree with yu. Clsing all the factries means many citizens in Beijing will lse their jbs. what's mre, Beijing will nt be able t develp better withut the ecnmical back up.
Oral Exercise
Suppsing yu are the expert f saving energy, nw yu are preparing a speech abut hw t save the wrld by urselves. Please prepare a ne-minute speech.
Teacher's Example
Gd afternn, bys and girls. I am ging t talk abut hw t save energy in ur daily life. First, we shuld reduce the release f carbn dixide like cutting ff the electricity when we may nt use them. secndly, the mst carbn dixide cmes frm the gasline vehicles. It is better t walk r bike as much as pssible.
What's mre, as a student, we can put mre effrt in develping mre cleaner energy withut releasing greenhuse gases! Every step cunts! let's wrk tgether!
1. Review the six suggestins 2. Review the useful expressins3. Listen t an interview4. Summarize useful expressins fr Agreement and Disagreement 5. Express the agreement and disagreement in an interview6. Present a speech f hw t save energy t thers
