Practice these TOEFL iBT listening tests to help you score high in the TOEFL Listening Section. Check the correct answers and audio transcripts below. This video is in the series of NEW TOEFL iBT Preparation: https://www.youtube.com/playlist?list=PL2jvSGmpWX1UMjbc8Onae7i-R6Z8VcPbU. Questions 1 through 2. Listen to part of a talk in an art class. If you are unsure of drawing directly in pen and ink, start off with a light pencil sketch. This will allow you to make sure that your proportions are correct and that you are happy with the composition. Take a few minutes to study your subject—this chair and violin. Notice how the straight lines of the chair differ from the curves of the violin. Once you are ready to begin drawing, define the shape of the chair with clean straight lines. Then add contrast by drawing the outline of the violin with gently curved lines. You may have to apply more pressure to the nib when drawing curved lines to allow the ink to flow easily. When you have drawn the outlines of both objects, add in the finer details, such as the seat of the chair and the violin strings. Suggest the texture of the woven seat by using light and dark strokes of the pen. Correct Answers: 1. C 2. Draw the outline of the violin. - YES Take a photograph of the subject. - NO Study the subject for a few minutes. - YES Rub the violin strings with a bow. - NO ---------------------- Questions 3 through 5. Listen to a geography professor talk about avalanche control. Avalanches are a constant threat on mountain highways. The Rogers Pass stretch of the Trans-Canada is at risk of being buried in snow from November to April every year. This is why the highway now has a sophisticated defense system. The best way ... it’s important to control an avalanche when it’s small ... so a slide is set off while it’s still small, before it builds up into a serious danger. A team of snow technicians monitors the snowpack. They sort of “read" the snow and try to predict when it's likely to slide. They study data from the weather stations in the mountains. As the danger increases, they drop explosives onto test slopes to see if the snow can be made to slide. It's kind of tricky trying to decide just when the snow will slide. The weight of the snow, together with the force of gravity, is what starts an avalanche. The technicians don’t want to wait till it's too late, but if they're too early, before conditions are just right, the snow won’t release. When the time is right, they close the road and remove all traffic from the pass. Most closures last two to four hours. Then the army comes in. A ten-man artillery crew operates a mobile 105 mm howitzer, firing shells into the slopes. This sends out shock waves that trigger the avalanches. Slides are set off, one by one. The technicians direct the action, telling the troops where to aim the gun. Visibility can be awful. Then they have to check and see if the avalanche has released well enough. Sometimes they drive their trucks below the slide path kind of dangerous work- and they listen to the snow come down. Sometimes, if the slide is bigger than they expected, they might have to make a speedy getaway. Correct Answers: 3. D 4. A & C 5. C-A-B-D
