三、课文
Neither Pine nor Apple in Pineapple
Have you ever asked yourself (1) why people often have trouble
learning English? I hadn' t, until one day my five-year-old son asked me
(2) whether there was ham in a hamburger. There isn' t. This made me
realize (3) that there' s no egg in eggplant either. (4) Neither is there pine
nor apple in pineapple. This got me thinking (5) how English can be a
crazy language to learn. 第 4 页 共 9 页 For example, in our free time we can sculpt a sculpture and paint a
painting, but we take a photo. And (6) when we are traveling we say that
we are in the car or the taxi, but on the train or bus! (7) While we' re
doing all this traveling, we can get seasick at sea, airsick in the air and
carsick in a car, but we don' t get homesick (8) when we get back home.
And speaking of home, why aren' t homework and housework the same
thing?
(9) If "hard" is the opposite of "soft" ， why are "hardly" and softly
not an opposing pair? (10) If harmless actions are the opposite of
harmful actions, why are shameless and shameful behaviors the same?
(11) When we look out of the window and see rain or snow, we can
say "it' s raining" or "it' s snowing" . But (12) when we see sunshine, we
can' t say "it' s sunshining" .
Even the smallest words can be confusing. (13) When you see the
capitalized "WHO" in a medical report, do you read it as the "who" in
"Who' s that? " What about "IT" and "US" ?
You also have to wonder at the unique madness of a language (14) in
which a house can burn up as it burns down, (15) in which you fill in a
form by filling it out, and (16) in which an alarm is only heard once it
goes off!
