a revolved light that is red then green. Or it may be 8.__________
only white. But however the signal, it is sent very 9.__________
regularly. A ship within its ranges is never at a loss to
know which lighthouse it is, and where it is being 10.__________
located
When some nineteenth century New Yorkers said "Harlem",
they meant almost all of Manhattan above Eighty-sixth Street.
Toward the end of the century, however, a group
of citizens in upper Manhattan-want perhaps, to shape a closer 1._________
and more precise sense of community—designated a section that
they wished to have known as Harlem. The chosen area was the
Harlem which Blacks were moving in the first decades of the 2.________
new century as they left their old settlements on the middle and
lower blocks of the West Side.
As the community became predominantly Black, the very
word "Harlem" seemed to lose its old meaning. At time it was 3.________
easy to forget that "Harlem" was originally the Dutch name
"Harlem"; the community it described had been founded by 4.________
people from Holland；and that for most of its three centuries—it
was first settled in the sixteen hundreds—it had been preoccupied 5.________
by White New Yorkers. "Harlem" became synonymous to 6.________
Black life and Black style in Manhattan. Blacks living there
used the word as though they had coined it on themselves—not 7.________
only to designate their area of residence but to express their
sense of the various qualities of its life and atmosphere. As the
years passed, "Harlem" asserted an even larger meaning. In 8.________
the words of Adam Clayton Powell, Sr., the pastor of the
Abyssinian Baptist Church, Harlem "became the symbol of liberty
and the Promised Land to Negroes everywhere".

majority part in designing it. 2.________

design for the president's house. The winner was a young man of 3.________

house of stone. And President Washington made some changes
in the winning design. He made the house long and wider, and 4.________
changed it into a two-storied house instead of three.
The second president, John Adams, was first to live in the 5.________
White House. When he and his wife moved onto the new house 6.________

live area was completed. The whole work did not finish until the 7.________
administration of the 3rd president, Thomas Jefferson.
There are great many reasons for studying what philosophers 1.________
have said in the past. One is that we cannot separate the
history of philosophy from which of science. Philosophy is 2.________
large discussion about matters on which few people are quite 3.________
certain, and those few hold opposite opinions. As knowledge
increases, philosophy buds off the sciences.
For an example, in the ancient world and the Middle Ages 4.________
philosophers discussed motion. Aristotle and St. Thomas
Aquinas taught that a moving body would slow down until a force 5.________
were constantly applied to it. They were wrong. It goes on moving
unless something slows it down. But they had good arguments on
their side, and if we study these, and the experiments
which proved them right this will help us to distinguish truth 6.________
from false in the scientific controversies of today. 7.________
Aphrodite loved Adonis more than she did to heaven, for 1.________
He was a brisk, lovely young hunter. She abandoned her residence
at Olympus and took to the woods, where she dressed
herself up like a huntress and kept the youth companion all day 2.________
long. With him she roved through bushy grounds and groves and
over hills and dales, cheering hounds and pursuing game of a
harmless sort. They had a great time together. However, she
warned him many times to chase wild beasts like lions and 3.________
wolves, but the young man just laughed at the idea.
One day, after warning him thus, she left to Olympus in 4.________
her chariot. Quite by chance Adonis' hounds found a boar, that 5.________
roused Adonis to enthusiasm. He hit the beast with a dart, and 6.________
the boar, turning on him ,buried its white tusk deep into his
tender side and trampled him to death.
When Aphrodite came back to find her lover cold in death,
she burst into a passion of tears. Unable to wrest him back from
the low world, she sprinkled nectar on Adonis' blood and 7.________
turned it into anemone, a delicate purple flower.
Expressing Yourself in English is an inter- esting new textbook with some variations from the traditional in its approach．They would 1．__________
seem appropriate for self-study，especially when used in conjunction with the cassette，but is primarily intended of classroom use．Indeed， 2．__________
the text itself contains notes to the teachers rather than that appearing in a separate teacher’s guide． 3．__________
Each unit contains three readings，all of which，except for those appearing in the ninth and the final unit，are illustrated．The teacher's notes indicate the teacher should refrain of 4．__________
answering students' questions about these readings until each student has worked through all the reading comprehension exercises without help． Among the book's distinctive features is the fact that contains a more extensive list of 5．__________
references than any other writing for this level， 6．__________
which exercises are provided and allow students to be creative with the English they learn． Again，like most comparable texts，Expressing 7．__________
Yourself in English does not formally introduce the verb until Unit 3．One hint for teachers and students likely is that students 8．__________
should not expect to be successful with the examinations offered in the body of the text if 9．__________
they study outside of class and memorize the dialogue that introduces each unit． In order to keep the price lowly，the book 10．__________
