And the more you read aloud, the more you know; and the more you know, the smarter you grow.So listen and read
14、 to the recording of the text. Pay attention to the pronunciation, stress and intonation. 3. Discovering useful words and expressionsTurn to page 40 and fill in the blank to complete the two exercises.4. Reading more about Davidson BlackDavidson Black (1884-1934)Davidson Black was born in Toronto, C
15、anada in 1884. He learned early on that good communication skills with other cultures would aide him in learning about them. Black not only befriended the Indians and learned their languages in his early days; he also got along extremely well with his Chinese colleagues. He was always eager to know
16、more and this progressed throughout his life. He earned a degree in Medical Science in 1906 from the University of Toronto, then went back to study comparative anatomy. By 1909, Black was an Anatomy Instructor. After realizing his passion for human evolution, he gained his big break. In 1919 he was
17、offered a position at Peking Union Medical College in China. In 1927, Black began an enormous excavation at Zhoukoudian, which is near Peking. It was there that a hominid lower molar of unusual distinction was discovered. After studying this tooth with intense focus, Black recognized the existence o
18、f a previously unknown hominid genus and species. He also pointed out the close relationships among Peking man and Pithecanthropus Erectus. Davidson Black inferred that the Peking man was a thinking being, standing erect, dating to the beginning of the Ice Age. Some scientists were skeptical of Blac
19、ks findings, and in 1928, while Black was traveling to validate his beliefs to other scientists, half of a lower jaw was found with three teeth still intact. But the evidence he was really looking for was in the discovery of skull of the first Peking man.In 1932, Black was elected a Fellow of the Ro
20、yal Society. His hard work and dedication carried him far in his experiments and discoveries, but the stress eventually got to him. He struggled with a congenital heart defect, which when he overworked would act up. He worked long days at his office, often returning again to work during the night, w
21、ith very minimal sleep. This obsession eventually lead to his death at age 49, in March of 1934, while working alone in his office at night.5. Revising the present perfect continuous tensePresent Perfect ContinuousFORM Present Perfect ContinuousHAS / HAVE + BEEN + VERB+ingEXAMPLES:I have been sittin
22、g here for two hours.She has only been studying Japanese for two years.NOTE: When you are using a verb tense with more than one part such as Present Perfect Continuous (has been studying), adverbs often come between the first part and the second part (has only been studying).USE 1 Duration from the
23、Past Until Now We use the Present Perfect Continuous to show that something started in the past and has continued up until now. “For five minutes“, “for two weeks“, and “since Tuesday“ are all durations which can be used with the Present Perfect Continuous. EXAMPLES:They have been talking for the la
24、st hour.She has been working at that company for three years.James has been teaching at the University since June.USE 2 Recently, Lately You can use the Present Perfect Continuous WITHOUT a duration such as “for five minutes“, “for two weeks“, and “since Tuesday“. Without the durations, the this ten
25、se gives a more general meaning of “lately“. We often use the words “lately“ or “recently“ in the sentence to strengthen this meaning.EXAMPLES:Recently, I have been feeling really tired.She has been watching too much television lately.Mary has been feeling a little depressed.IMPORTANTRemember that t
26、he Present Perfect Continuous has the meaning of “lately“ or “recently.“ If you use the Present Perfect Continuous in a question such as “Have you been feeling alright?“, it suggests that the person looks sick or unhealthy. A question such as “Have you been smoking?“ suggests that you can smell the
27、smoke on the person. Using this tense in a question suggests you can see, smell, hear, or feel the results of the action. It is possible to insult someone by using this tense incorrectly.IMPORTANT Non-Continuous Verbs/ Mixed VerbsIt is important to remember that Non-Continuous Verbs cannot be used i
28、n any continuous tenses. Also, certain non-continuous meanings for Mixed Verbs cannot be used in continuous tenses. To express the idea of Present Perfect Continuous with these exception verbs, you must use Present Perfect.EXAMPLES:Sam has been having his car for two years. Not CorrectSam has had hi
29、s car for two years. CorrectACTIVE / PASSIVE Present Perfect ContinuousEXAMPLES:Recently, John has been doing the work. ACTIVERecently, the work has been being done by John. PASSIVENOTE: Present Perfect Continuous is rarely used in its passive form.6. Discovering useful structuresNow turn to page 40 and do exercises 1, 2 and 3. 7.
