I. Read the text. Choose the most suitable heading from the list (a-g) for each part (1-5) of the text. There are two extra headings which you do not need to use.

A. Thompson’s Main Scientific Interest.

B. Scientific Reasoning of That Time.

  1. Work and Reward.

  2. The Result of Thompson’s reasoning.

E. Excellent Teacher.

F. Thompson and His Collegues.

G. The Nature of Rays and Particles.

II. Read the text. For statements (6-15) choose “True” if the statement is true according to the text, “False” if the statement is false:

  1. The atom is a part of particles.

  2. Thomson called particles electrons.

  3. German physicists thought that visible rays were created in the ether.

  4. British and French physicists considered visible rays to be electrically neutral particles.

  5. X-rays were made up of the same particles.

  6. Types of conductors didn’t influence the composition of the particles.

  7. Corpuscles could be also produced from hot metals.

  8. When an atom contains many electrons their mass can be equal to the mass of the atom.

  9. Einstein’s theory of photons heralded Thompson’s hypothesis.

  10. Thompson became the winner of the most significant prize in science for the discovery of the electron.

III. Read the text. For questions (16-20) choose the correct answer (a, b, c or d).

16) Thompson’s conclusion was that all matter …

a) had to be considered.

b) is necessary for lectures.

c) consists of tiny particles.

d) has the same properties.

17) His discovery was …

a) the consequence of his work.

b) a bad shot to solve the controversy.

c) false.

d) held with the help of his collegues.

18) Nearly all scientists of that time …

a) thought that rays were produced in the either.

b) agreed with Thompson.

c) helped Thompson in his work.

d) could produce rays in the either.

19) Thomson managed to …

a) give lectures and work simultaneously.

b) write some scientific books

c) prove that rays were made of particles.

d) give the explanation of an improved vacuum technique.

20) By the turn of the century most of the scientific world …

a) approved Thomson’s discovery.

b) ignored Thomson’s discovery.

c) rejected Thomson’s discovery.

d) laughed at Thomson’s discovery.
