Mixing concrete
Concrete mixers mix and pour concrete. For small quantities of concrete, hand mixers are
ideal. The portable mixer has wheels and uses electricity. It has a small drum which rotates.
Concrete transport trucks - or in-transit mixers - transport large quantities of concrete to the site.
The drum rotates during transport. The chute man pours the concrete down the chute, or uses a
pump to get the concrete to difficult locations. Sometimes a crane lifts a hopper full of concrete
to the job site.

People read in many different places, for example in a park, on a bus, or in a car. This is because
books, newspapers, magazines, and so on, are easy to carry. We also read in many different
ways, and at different speeds.
Sometimes we read quickly. We just want to get the general idea from a newspaper article, a
report, or a book in a bookshop. Perhaps we want to know what it is about, or if it is interesting
or important. We call this type of reading ‘skimming’. We also read quickly to get a particular
piece of information, such as a date, a telephone number, or the name of a restaurant. This is
called ‘scanning’. We scan timetables, telephone directories, dictionaries, and web pages.
