Unit 17 · Global Warming and Climate Change
Getting started
Global warming and climate change
Look at the pictures and discuss the causes and consequences of global warming and climate change.
A model discussion
Kopila:In the first picture, a polar bear is standing on a tiny piece of ice. The sea ice is melting because the Arctic is warming.
Nabin:Yes, and the bear hunts seals from the ice. If the ice disappears, it can’t find food.
Kopila:The second picture shows a mountain with very little snow. That is happening in our Himalaya too: the glaciers are shrinking and the snow line is moving higher.
Nabin:And the third one shows a town destroyed by a storm. Warmer seas make storms stronger.
Kopila:The main cause is the greenhouse gases we add to the air, mostly by burning coal, petrol and diesel and by cutting down forests.
Nabin:So the consequences are melting ice, rising seas, stronger storms, floods and droughts. In Nepal it means glacial lake floods, landslides after heavy rain, and less water in the dry season.

Model answers
- a.My favorite movie is WALL-E, an animated film by Pixar.
- b.It is an animated science fiction film: a cartoon story set in the future.
- c.I like the little robot WALL-E, who goes on cleaning up an Earth covered in rubbish long after people have left it, and the way the film makes you laugh and think at the same time. Its weakness is that the second half, on a spaceship, moves too fast and is less moving than the quiet first half.

Some answer keys give Los Angeles for b, reading “opens in Los Angeles on Nov. 23” as the place where the film is set. But a film that opens somewhere is first shown in cinemas there; it says nothing about where its story begins.
D. Answer the questions
What kind of film is Chasing Ice?
Answer
It is a documentary (and a biography): a film of real events, following the real work of the photographer James Balog.
What is the main objective of the film?
Answer
To show, with real pictures, how fast glaciers are melting because of climate change, so that viewers, even skeptics, see the evidence for themselves and think seriously about the future.
Why did Balog and his team set up cameras in different places?
Answer
To record the same glaciers over a long time: the cameras took pictures again and again for years in Greenland, Iceland, Alaska and Montana, so the footage would show how much each glacier changed.
What helps the audience experience what is happening in the Arctic zones?
Answer
Balog’s photographs and time-lapse footage of glaciers calving, breaking apart into icebergs. They let viewers see places most people will never visit.
How did Balog try to make the film interesting?
Answer
He combined data and scientific facts with beautiful pictures, and he did not overwhelm viewers with too many scientific details: he explained his methods and results simply, without being boring. Dramatic scenes (disasters, avalanches, calving glaciers, his own risks) keep it exciting too.
Why is Chasing Ice a worthwhile film?
Answer
Because it combines intriguing theories and exquisite images, it shows real evidence of melting glaciers, and it makes viewers, even skeptics, think critically about climate change and what it means for our future.
E. Slowing climate change
Work in a group of four or five. Suggest five practical ways to slow down the adverse effects of climate change.
A model answer
- Use less fossil fuel. Walk or cycle for short trips, share rides, and use public buses and electric vehicles. Almost all the electricity Nepal makes comes from its rivers, so an electric bus or cooker in Nepal adds very little carbon dioxide.
- Save energy. Switch off lights and fans we are not using, and use LED bulbs and pressure cookers.
- Plant and protect trees. Community forests have made Nepal’s hills greener since the 1980s; trees take carbon dioxide out of the air and hold the soil on slopes.
- Waste less. Reduce, reuse and recycle; compost kitchen waste instead of letting it rot in a landfill, where it gives off methane; never burn plastic.
- Prepare for the changes already coming. Build away from river banks, keep early-warning systems for glacial lakes and floods, collect rainwater, and grow crops that survive drought.
Pronunciation: /ʊ/ and /uː/
Read the words in the box below with the correct pronunciation. Put them in the correct groups.
food book cook foot moon noon roof room good school look hook stood took soon wood too zoo zoom wool
Answer
| /ʊ/ (short, as in book) | /uː/ (long, as in food) |
|---|---|
| book, cook, foot, good, look, hook, stood, took, wood, wool | food, moon, noon, roof, room, school, soon, too, zoo, zoom |
Some answer keys put zoo and zoom in the short column and wool in the long one: it is the other way round. A rule of thumb: -ook words are short (book, cook, look, hook, took), and so are good, stood, wood, foot, wool. An oo at the end of a word is always long (too, zoo). Roof and room are said long in most English; you may hear them short too.
Speaking: how sure are you?
B. Situations
Work in pairs. Have similar conversations in the following situations using must, can’t, may or might.
Example: Suman is not at home. These are office hours. A: Where is Suman? B: He must be in his office.
- a.They are coming this week, but I am not sure. They will probably come tomorrow.
- b.Dolma is not sure that she will pass the exam.
- c.Shishir has bought a lottery ticket. He could become a millionaire.
- d.Rajesh looks like a foreigner. He speaks excellent French.
- e.Sambriddhi has got a job. I’m sure she is very happy.
- f.I hope to finish the project tonight. However, I am not sure.
- g.There is somebody at the gate. They always come at eight. I am sure they are road cleaners.
Model conversations
- a.A: When are they coming? B: I’m not sure. They may come tomorrow.
- b.A: Will Dolma pass the exam? B: She might not pass: she isn’t sure herself. (Or: She may pass, but she isn’t sure.)
- c.A: Why is Shishir so excited? B: He has bought a lottery ticket. He might become a millionaire! (A small chance: might, or could.)
- d.A: Where is Rajesh from? B: He might be from France: he looks like a foreigner and speaks excellent French. (Not must: many people learn French without being French.)
- e.A: How is Sambriddhi? B: She has got a job. She must be very happy.
- f.A: Will you finish the project tonight? B: I may finish it tonight, but I’m not sure.
- g.A: Who is at the gate? B: It’s eight o’clock. They must be the road cleaners.
C. At a party
You met a friend at a party and started talking about your day. Ask his/her opinions about the things below. Your friend will answer you using “must”, “can’t”, “may” or “might”.
- a.My father wasn’t in a very good mood today when I reached home from school.
- b.My English teacher got a phone call during the class and left the room immediately. He looked very worried at that time.
- c.My friend Pratima looked very pleased today when she returned back to the class from the principal’s office.
- d.Someone’s stomach in the class made a growling sound. I do not know why she/he had that problem.
- e.A friend of mine was terribly worried after the English test.
Model conversations
- a.A: My father wasn’t in a good mood when I got home. Why do you think? B: He must have had a hard day at work. Or he might have heard some bad news.
- b.A: My English teacher got a call and rushed out, looking worried. B: Something serious must have happened at home. Someone in his family might have fallen ill.
- c.A: Pratima came back from the principal’s office looking very pleased. B: She must have got good news. She may have won the essay competition!
- d.A: Someone’s stomach growled in class. Why? B: She or he must have missed breakfast. They can’t have eaten anything since morning.
- e.A: My friend was terribly worried after the English test. B: She might have made some mistakes. Or she can’t have finished all the questions in time.
Grammar I: talking about the future
A. Fill in the gaps
Fill in the gaps with the correct forms of the verbs in the brackets.
- a.I ……… (have) no time to do any additional projects next year.
- b.Sambriddhi ……… (finish) her homework before her parents returned home.
- c.My uncle ……… (learn) to talk in English by the time he finishes this course.
- d.Sandeep ……… (stay) at ours till Monday.
- e.The workers ……… (build) the building for the next two months.
- f.You ……… (find) the meaning of the unfamiliar words in an hour.
- g.We ……… (stay) in Damauli until next Saturday.
- h.I think our team ……… (win) the match.
- i.By 11 p.m. tonight, she ……… (prepare) the report.
- j.After I finish my work tonight, I ……… (watch) TV for some time.
- k.The weather forecast says that it ……… (rain) heavily today.
Hint
Look for the time words: next year, by, for the next, until, tonight, I think. One of the sentences is about the past: which?
Answer
- a.will have (a future fact: next year)
- b.had finished: returned is in the past, so this sentence is about the past, and the homework was done before her parents came: the past perfect. (About the future, it would be Sambriddhi will have finished her homework before her parents return home.)
- c.will have learned (by the time he finishes: finished before then)
- d.will stay or will be staying (until Monday)
- e.will be building (for the next two months: going on over that time)
- f.will find (in an hour from now; or will have found, done within the hour)
- g.will stay or will be staying
- h.will win (a prediction: I think)
- i.will have prepared (by 11 p.m.: finished before then)
- j.will watch (a single future action after another)
- k.will rain (or is going to rain: a forecast)
Some answer keys give will have been building for e. That form needs a point in the future to measure up to (By June, they will have been building it for two months); with for the next two months, the action is simply going on, so will be building. And some give will have finished for b, which doesn’t fit a sentence that ends in the past, returned.
B. Visiting Her Majesty
Rewrite the paragraph “Visiting Her Majesty” using the verbs in the future tense.
Hint
There are fourteen past verbs: travelled, disguised, walked, stepped, surprised, tipped, bowed, delivered, exchanged, talked, showed (twice), traded, kissed. Change each one, and leave everything else as it is.
Answer
It begins: I will travel to London to visit the Queen of England. I will disguise myself as a prince and walk into Buckingham Palace. After receiving directions from a chambermaid, I will step into the Queen’s bedroom and surprise Her Royal Highness with a hearty slap on the back.
The rest of the verbs:
| Past | Future |
|---|---|
| I tipped my hat, bowed, and delivered | I will tip my hat, bow, and deliver |
| we exchanged pleasantries and talked | we will exchange pleasantries and talk |
| I showed her my photograph album | I will show her my photograph album |
| She showed me her jewels | She will show me her jewels |
| I traded email addresses … and then kissed her goodbye | I will trade email addresses … and then kiss her goodbye |
Of course and After uncorking a bottle of champagne stay as they are. The British spelling travelled becomes travel in any case.
Writing I: a movie review
Write a short review of your favorite movie. You may use the movie review in Reading I as a model.
Hint
Use the five parts. Keep the story to one paragraph and give at least as much space to your opinion, with reasons. Remember: present tense for the story, and no spoilers.
A model review
Movie Review: WALL-E
Title: WALL-E · Genre: animation, science fiction · Director: Andrew Stanton · Studio: Pixar · Language: English · Released: 2008 · Runtime: 1 hour 38 minutes
Seven hundred years from now, the Earth is buried under mountains of rubbish, and the humans have left it to live on a giant spaceship. Only one small robot, WALL-E, is still working, squeezing the garbage into cubes, day after day, with a cockroach as his only friend. Then a sleek white robot called EVE arrives from space to look for signs of life, and WALL-E follows her across the galaxy.
The first half of the film is a small miracle: there is almost no talking, yet you understand every feeling of the lonely robot, through his eyes, his little sounds and the way he collects treasures from the junk. The pictures of the empty, dusty Earth are beautiful and sad at the same time. The film also has a serious message about waste and about people who let machines do everything for them.
Its weakness is the second half: the scenes on the spaceship are busy and noisy, and the humans are drawn as cartoons, so the film loses some of its quiet magic.
Still, WALL-E is funny, moving and clever, and it won the Oscar for the best animated film. I recommend it to everyone from eight to eighty, especially to anyone who has ever thrown a plastic bag on the ground.
Reading II: A Noisy Party
Before you read
- a.Where do you think the man is?
- b.How old do you think he is?
- c.What might he be doing?
Model answers
- a.He might be in his garden, or in a field near his house.
- b.He must be about forty or fifty years old: he isn’t young, but he is strong enough to dig.
- c.He might be digging a hole to plant a tree or vegetables, or to bury some rubbish. (Read the play to find out what he is really doing!)
A. Find the words
Find the words from the text above that match with the given meanings.
- a.a situation that you must deal with
- b.unpleasant, horrible
- c.noisy quarrel
- d.expression of surprise
- e.a small orange or red fish
- f.to put something under the ground
Answer
a. matter b. disgusting c. row d. gosh e. goldfish f. bury (burying in the text)
C. True, false or not given
Write T for true statements, F for false ones and NG if the information is not given in the text.
- a.Silu is the daughter of Ramesh and Ramila.
- b.Ramesh and Ramila are disturbed by the first noise at midnight.
- c.The Dahals have a good relationship with their neighbors.
- d.The Dahals always quarrel after parties.
- e.Ramesh and Ramila called the police to arrest Mr. Dahal.
- f.Mr. Dahal wants his children to know about the death of the fish.
Hint
NG means the text doesn’t tell you either way. F means the text shows it is wrong.
Answer
- a.T. Ramila calls Ramesh Silu’s Papa, so Silu is their child, and Silu is a common Nepali girl’s name, so she is their daughter.
- b.F. The first noise wakes them at half past one, not midnight.
- c.NG. The text doesn’t say how the families get on. (Ramesh’s They never invite us is a hint, but no more.)
- d.F. Ramila says they always have rows after parties, but that is only her guess, and this night shows it wrong: the crash they took for a row was the goldfish tank, knocked over while the Dahals were clearing up together.
- e.F. Ramesh wanted to, but Ramila told him to ask Mr. Dahal first, and they never called.
- f.F. He is burying the fish before the children wake up, so that they won’t see the dead fish: he does not want them to know.
Some answer keys give T for f. But burying the fish before the children wake shows the opposite: he wants to spare them.
D. Disturbed at night
Have you ever been disturbed in the middle of the night? What happened? Share your experiences with your friends.
A model answer
Last Tihar, I was woken at about two in the morning by loud bangs and shouting outside. My heart was racing: I was sure someone was breaking into our neighbor’s shop. My brother and I crept to the window. It turned out to be a group of young men from our tole, still playing Deusi and setting off the last of their firecrackers on the way home. The next morning, my mother laughed at us for being so frightened. Like Ramila and Ramesh, we had jumped to conclusions from the sounds alone.

Enquire is the British spelling; American English writes inquire. In e, who is the subject, so the order stays. In j, could doesn’t change: it is already a past form.
C. Your own questions
Collect at least ten statements and change them into wh-questions. Swap with a partner and check each other’s answers.
Ten model pairs
- Bina reads the news every morning. → When does Bina read the news?

Exercise
Read the text and answer the questions.
In the 1950s, there was no lake below Island Peak in Khumbu, only the long tongue of Imja Glacier covered in rocks. In the 1960s, small ponds appeared on the glacier’s surface. As the ice melted, they joined into one lake, Imja Tsho, which kept on growing. By 2010 it was about two kilometers long, held back only by a wall of loose rock and ice. Scientists worried that the wall might burst and send a flood down to the villages of the Imja and Dudh Koshi valleys.
