Vocabulary
1 Fill in: melt, greenhouse, footprint, dissolve, patterns, threat, exhausts, extinct.
1 There arentaskt any wild wolves in Britain anymore. They became extinct 250 years ago.
2 When the polar ice caps melt, the sea level rises.
3 Carbon dioxide is a greenhouse gas.
4 A lot of animals are losing their habitats and dying; the number of animals under threat is increasing all the time.
5 We should all try to reduce our carbon footprint.
6 Car exhausts produce gases that surround the earth.
7 Changing weather patterns threaten a lot of animals with extinction.
8 Acid rain can even dissolve the stone we use for buildings.
2 Choose the correct word.
1 Carbon dioxide is dangerous because it traps heat in the Earth’s atmosphere.
2 Arctic polar bears are in danger of losing their natural habitat.
3 Global warming is causing the Earth to heat up.
4 Power plants burn fossil fuels like coal to create energy.
5 Dangerous gases like carbon dioxide surround the Planet.
6 The ice sheets that cover Greenland and Antarctica are melting rapidly.
7 Scientists believe that global warming may be the cause of extreme weather such as floods.
Reading
3 Read the text. Five sentences are missing. Match each sentence (A-F) to a gap (1-5). There is one extra sentence.
If you’re having an outdoor party or a picnic, you don’t want a storm to ruin it for you. In the same way, if you’re a farmer, you need the sun to shine and the rain to pour at the right time for the best crops. 1) So imagine a world in which we could control the weather! Well, some scientists believe that they can do just that!
One way to control the weather that scientists have already used is ‘cloud seeding’. 2) This involves firing a rocket containing silver iodide into a cloud. When you do this, drops of water in the clouds attach to the particles to make raindrops. Believe it or not, in China there is a “Weather Modification Office” that often uses cloud seeding! 3) It claims that it has stopped hailstorms, ended droughts and even put out fires.
In 2008, it used 1,104 cloud-seeding rockets to keep the opening ceremony of the Olympic Games dry. It ‘seeded’ the clouds before they got to Beijing, so it didn’t rain on the athletes. In other places, scientists have also ‘seeded’ clouds with dry ice to get rid of fog at airports. 4) Cloud-seeding can go wrong, though! In 2009, Chinese meteorologists were trying to create rain during a drought when a cold front arrived and turned the rain into a heavy snowstorm. Beijing froze and there was chaos on the roads!
Some scientists don’t believe that we can really control the weather, but others think that in the future, we will be able to control it with ‘nanobots’ or microscopic robots.
These nanobots could make changes in the atmosphere and stop storms before they form. 5) If this works, it will reduce the number of natural disasters like hurricanes and floods. Until then, though, we’ll have to keep an eye on the weather report and take an umbrella to our picnics, just in case!
A This involves firing a rocket containing silver iodide into a cloud.
В If this works, it will reduce the number of natural disasters like hurricanes and floods.
C So imagine a world in which we could control the weather!
D Cloud-seeding can go wrong, though!
E It claims that it has stopped hailstorms, ended droughts and even put out fires.
F If theretasks a clear blue sky, cloud-seeding wontaskt work.
