Today I would like to test your listening skills with an interesting video from TED. I picked this one because it is actually pretty similar to some of the content in the IELTS listening test. I have written some questions to go along with it. These will help you deal with some of the important skills necessary for IELTS listening success.
First, though, we will learn some vocabulary.

Table Completion
Listen again and complete the gaps in this table. Use ONE WORD OR NUMBER from the recording.
Temperature | Result |
92 degrees Fahrenheit | Butter ___7____, making the dough spread. Trapped ____8____ is released. |
__9__ degrees Fahrenheit | Salmonella die off. |
144 degrees Fahrenheit | Changes start to happen with the ____10____, which most comes from eggs. |
212 degrees Fahrenheit | ___11___ boils, causing cracks in the cookie’s surface. Steam makes air pockets that make the cookie ___12___ and flaky. |

Fill in the Blanks
Start listening from 02:50 and fill in the blanks for this section. Use NO MORE THAN THREE WORDS OR A NUMBER from the recording.

When your ____18____ reaches that temperature, they die off. You’ll live to test your fate with a bite of raw dough you sneak from your ____19____. At 144 degrees, changes begin in the proteins, which come mostly from the eggs in your dough. Eggs are ____20____ dozens of different kinds of proteins, each sensitive to a different temperature. In an egg fresh from the hen, these proteins look like coiled up ____21____. When they’re exposed to heat energy, the protein strings unfold and get tangled up with their ____22___. This linked structure makes the runny egg nearly solid, giving substance to squishy dough.
