2018年專八語言知識練習題二It is hardly necessary for me to cite all the evidences of the depressing ____(1)____state of literacy. These sums from the Department of Education are ____(2)____sufficient: 27 million Americans cannot read at all, a further 35 million read on a level that is less than sufficient to survive in our society. (3) But my own worry today is more that of the overwhelming problem of____ (4)____elemental literacy than it is of the slightly more luxurious problem of the decline in the skill even of the middle-class reader, of his unwillingness to afford those spaces of silence, those luxuries of domesticity and time and concentrating,____ (5)____that surrounds the image of the classic act of reading. It has been suggested____ (6)____that almost 80 percent of America's literate, educated teenagers can no longer read with accompanying noise (music) in the background or a television screen flickered at the corner of their field of perception. We know____ (7)____very little about the brain and how it dealt with simultaneous conflicting ____(8)____input, but every common-sense intuition suggests we should be profoundly alarmed. This violation of concentration, silence, solitude goes to the very heart of our notion of literacy; this new form of part— reading, of partperception against background distraction, enders impossibly certain____ (9)____essential acts of apprehension and concentration, leave alone that most important tribute any human being can pay on a poem or a piece of prose he or ____(10)____she really loves, which is to learn it by heart. Not by brain, by heart; the expression is vital.
答案和解析:
1. evidences—evidence. evidence 爲不可數名詞，不能使用復
數形式。
2. sums—改成figures。sums 表示“總和”，但後面列舉了一些具體數字，與總和並無多大關係。因此sums應改爲figures。figures意即“數字”。
3. on—at。表示“在„„水平上”時，level 前須用介詞at。
4. more—less。more A than B意即“與其說B，倒不如說A”而less A than B則表示與其說A，倒不如說B”。根據上下文，此處more應改爲less。
5. concentrating—concentration。 and前後成分應對等，由於and前面是名詞，其後面也應該用名詞。因此concentrating應改爲concentration。
6. that—which。這兒which用來指代前面的整個句子。
7. flickered—flickering，flicker爲不及物動詞，不宜使用過去分詞形式作定語，故用現在分詞形式作定語。
8. dealt—deals。該文章主要採用一般現在時，因此dealt應改爲得deals。
9. impossibly —impossible。render sth + adj爲一常用結構，表示“使„„如何”。如果其中賓語太長，可將其後置。顯然impossibly 應改爲impossible
—to。pay tribute to sb/sth，系常用短語，意即“稱讚某人⁄某物”。故on應改爲to。
