6. Read the paragraphs (A-G), find the key words that can help you make a choice and match the paragraphs to the pictures of Ex. 1 on p. 93. Add the information you know.

A. This is an instrument that converts voice and sound signals into electrical impulses for transmission by wire to a different location, where another object receives the electrical impulses and turns them back into sounds. Alexander Graham Bell invented it in 1875.

B. There are many major milestones in its history, starting in 1936, when Konrad Zuse built the first freely programmable machine.

C. In 1884, Paul Nipkow sent images over wires using a rotating metal disk technology with 18 lines of resolution. This invention then evolved along two paths, mechanical and electronic. American Charles Jenkins and Scotsman John Baird followed the mechanical model while Philo Farnsworth, working independently in San Francisco, and the Russian emigrant Vladimir Zworykin, working for Westing- house and later RCA, advanced the electronic model.

D. In 1769, the very first road vehicle was invented by the French mechanic, Nicolas Joseph Cugnot. However, it was a steam-powered model. In 1885, Karl Benz designed and built the world’s first practical model to be powered by an internal- combustion engine.

E. In 1814, Joseph Nicephore Niepce created the first photographic image with a camera obscura, however, the image required eight hours of light exposure and later faded. Louis-Jacques-Mand Daguerre is considered the inventor of the first practical process of photography in 1837.

F. The first functional machine of this kind was invented by the French tailor, Barthelemy Thimonnier, in 1830. In 1834, Walter Hunt built America’s first successful machine of this kind. A little later Isaac Singer invented the up-and-down motion mechanism.

G. This medicine was discovered by Alexander Fleming in 1928. Andrew Moyer patented the first method of industrial production of it in 1948.

8. Work in two teams. One team says a word related to science or technology. The other team makes up a sentence using the word. Each correct sentence gets a point. The team with the most points is the winner.

Example

Team A S1: A vacuum cleaner

Team B S1: A vacuum cleaner is used to clean the carpets.
