Answer

All eleven words come from this chapter. Five can be counted and six cannot.

Countable NounsUncountable nouns
HelmetTraffic
BusesPollution
CarsSpeed
PedestrianSafety
BicycleTransportation
Fuel

Why each one goes where it goes:

WordC or UWhy
TrafficUWe say a lot of traffic, never three traffics.
PollutionUIt is dirt in the air and water. We cannot count it.
HelmetCOne helmet, two helmets.
BusesCThree buses came to the stop.
CarsCFive cars were waiting at the light.
SpeedUWe say at great speed. It is how fast something moves, not a thing we can count.
PedestrianCOne pedestrian, many pedestrians.
BicycleCTwo bicycles are kept in the shed.
SafetyUSafety is an idea, not a thing. We cannot say two safeties.
TransportationUIt means the carrying of people and goods. We cannot count it.
FuelUPetrol and diesel are liquids. We say a litre of fuel.
The pattern to remember: Things we can hold and count one by one — helmet, bus, car, pedestrian, bicycle — are countable. Ideas and things that come in an amount — traffic, pollution, speed, safety, transportation, fuel — are uncountable. The book’s own rule says a noun names a person, place, thing or an idea, and it is the idea words that are usually uncountable.
Note about the book: The table printed on page 33 has seven blank rows in each column, but there are only eleven words in all. So some rows will be left empty — five in the first column and six in the second.
