Background Information ( 5 minutes)1)Liberal artsThe term liberal in liberal arts originally meant “appropriate for free men,” i.e., among the Romans, only freemen were permitted to pursue them. In modern times the liberal arts refer to college or university subjects such as literature, history, and political science.2)Some successful women in scienceAlthough science and mathematics are usually regarded as “masculine”subjects, many successful women in these fields proved that those subjects do not belong to men alone. For example, Marie Curie (1867-1934), a French physicist and Nobel Prize winner, working together with her husband, performed ground-breaking studies of radioactive elements, including the discovery of two such elements, radium and polonium. Their work contributed greatly to the understanding of atoms on which modern nuclear physics is based.One of the Curie’s daughter, Joliot Curie (1897-1956) shared the 1935 Nobel Prize for chemistry with her husband for their work in the synthesis if radioactive substances.Emmy Noether (1882-1935), a German mathematician, was noted for her work in abstract algebra.Her work on the theory of invariants was used by Albert Einstein in formulating some of his relativistic concepts.Marie Goeppert Mayer (1906-1972), a German-American physicist, was best known for her study of nuclear structure. She shared the 1963 Nobel Prize in physics.Dorothy Crowfoot Hodgkin (1910-1994), a British chemist and Nobel laureate, was well-known for her use of X-ray diffraction to study the structure of macromolecules. She was awarded the 1964 Nobel Prize.2.

Paragraph Five1) Comprehension QuestionsQ:Why do girls avoid mathematics courses?A: Girls avoid mathematics courses mainly for social reasons rather than being afraid of the difficulty.2)Main ideaBoth boys and girls tend to regard subjects like mathematics and science as difficult.3) Difficult sentences“Interestingly, both boys and girls tend to regard such “masculine” subjects like mathematics and science as difficult”It is interesting that both boys and girls often look upon these boys’ subjects like mathematics and science as difficult.Paragraph Six1)Comprehension QuestionsQ: Why don’t the teenage girls like to take mathematics and science up?A:Because girls regard mathematics and science as “masculine” subjects, they are less likely to take them up.2) Main ideaMathematics and science are mainly masculine subjects, so the teenage girls are less likely to take them up.3) Sentence structurethey are less likely to take them upbe likely to do: tend to do sth.e.g.Are you likely to be in London this year?III.

Nevertheless, recent reports have suggested that even from their early nursery school days, girls are not encouraged to work independently, while boys are encouraged in schools by their teachers’ expectation that they can do better than girl students. Another possible reason is that girls regard mathematics and science as difficult “masculine” subjects and avoid them, although both boys and girls think these subjects are difficult.II.
