IELTS Reading: Task 10, Matching Sentence Endings
Matching Sentence Endings:
This is not a common question on IELTS reading exams as sentence completion is more customary. Match sentence endings have two types of listings that you have to bring together: 1. There is a list of incomplete sentences and 2. A list of potential sentence endings. The test taker has essentially to use the correct sentence ending to complete each incomplete sentence. However, there is some difficulty as there will be more sentence endings than sentences. So, eliminating the obvious ‘wrong’ sentence endings is useful, too. Therefore, the emphasis is more on grammar than paraphrasing and synonyms. Hence, parts of speech or what type of word (noun, verb, adjective, adverb, preposition, conjunction, or pronoun) will logically follow to complete the blank is important. Only one of the ‘endings’ will fully match or complete the sentence.
This is a good task to eliminate possible answers because the awkward connection between the two parts of sentences can be quite noticeable – it is obvious they do not fit -, and the answers appear in the same order as the list of incomplete sentences.
There will be two lists of sentences: 1. A list of incomplete sentences 2. A list of sentence endings.
Procedure
-
- Try to understand the meaning of the incomplete sentences and highlight keywords and phrases.
- Read the endings of the sentence (or answer statements) and try to understand what they mean.
- Try to match the first sentence ending with its correct sentence – note that many possible sentence endings can be eliminated because they are either not grammatically correct or the meaning does not correlate to the front part of the sentence.
- Read the first incomplete part of the sentence and try to understand its meaning. Then read through the sentence endings – though synonyms and paraphrases will be used, you should find one or two answers – eliminate the others.
- In the text, look for your keywords to locate the correct area of the text that contains the same meaning as the sentence and sentence-ending you are looking for – the text will not be very long; the correct answers should come quickly.
- Make sure that once you have matched the sentence parts together, that they are grammatically correct.
- Enter your answer on the answer sheet (A, B, C, etc.)
Note: Answers follow in the same order of the text

| How do Carburetors workCarburetors vary quite a bit in design and complexity. The simplest possible one is essentially a large vertical air pipe above the engine cylinders with a horizontal fuel pipe joined onto one side. As the air flows down the pipe, it has to pass through a narrow kink in the middle, which makes it speed up and causes its pressure to fall. This kinked section is called a venturi. The falling pressure of the air creates a sucking effect that draws air in through the fuel pipe at the side.
The airflow pulls in fuel to join it, which is just what we need, but how can we adjust the air-fuel mixture? The carburetor has two swiveling valves above and below the venturi. At the top, there’s a valve called the choke that regulates how much air can flow in. If the choke is closed, less air flows down through the pipe and the venturi sucks in more fuel, so the engine gets a fuel-rich mixture. That’s handy when the engine is cold, first starting up, and running quite slowly. Beneath the venturi, there’s a second valve called the throttle. The more the throttle is open, the more air flows through the carburetor, and the more fuel it drags in from the pipe to the side. With more fuel and air flowing in, the engine releases more energy and makes more power and the car goes faster. That’s why opening the throttle makes a car accelerate: it’s the equivalent of blowing on a campfire to supply more oxygen and make it burn more quickly. The throttle is connected to the accelerator pedal in a car or the throttle on the handlebar of a motorcycle. The fuel inlet to a carburetor is slightly more complex than we’ve described it so far. Attached to the fuel pipe there’s a kind of mini fuel tank called a float-feed chamber (a little tank with a float and valve inside it). As the chamber feeds fuel to the carburetor, the fuel level sinks and the float falls with it. When the float drops below a certain level, it opens a valve allowing fuel into the chamber to refill it from the main gas tank. Once the chamber is full, the float rises and closes the valve, and the fuel feed switches off again. (The float-feed chamber works a bit like a toilet, with the float effectively doing the same job as the ballcock—the valve that helps a toilet refill with just the right amount of water after you flush. |
