English was first spoken by the AngloSaxons who invaded England in the fifth century. They passed onto us the basic vocabulary of English. In over 15 centuries of its development, English has enriched itself by massive borrowing. As British immigrants landed in America and established the United States as an independent nation, a new variety was added to the English language: American English. Though some people worry that the language is running out of control, many native speakers of English take pride in the tolerance of their language.Unit 7 Text BComprehension Check:16: c c c d b dTranslation:1. 這一過程在幾個(gè)方面都是前所未有的：英語(yǔ)使用人數(shù)的增加，英語(yǔ)在不同社會(huì)滲透的深度，以及英語(yǔ)功用的廣度。 c – 6)。 e – 4)。 d – 2)。4. 此外，給我?guī)硇律畹?，與其說是自己努力取得的結(jié)果（雖然這也很重要），不如說是由于意識(shí)到自己具有潛在的能力可以做自己想做的事。3. 我下定決心往前走。 g – 8)2. 1) aid 2) inclined 3) in good health 4) shortings 5) penetrated 6) dismiss 7) has suffered from 8) progressive 9) optimistic 10) to a degree 11) hold on to 12) installUnit 6 Text ALanguage Sense Enhancement:1) limit 2) denying 3) favor 4) others 5) relevant 6) translating 7) hard and fast conclusions 8) focus 9) incredibly flexible 10) consider the possibility Vocabulary:I. 1. 1) cultural/ culture 2) indication 3) miniature 4) ironic 5) stumbled into 6) decent 7) buzzing 8) abnormal 9) mechanical 10) Shuddering 11) implied 12) leap2. 1) … convert RMB into US dollars in the foreign exchange office at the airport2) … didn’t know the first thing about cooking as she looked puzzled as to how to cook rice with the rice cooker3) … their faulty equipment the team had acplished some very useful work4) … allowing me to work flexible hours as long as I work eight hours a day5) …couldn’t help thinking the book must be quite fascinating3. 1) will not panic/ feel panic, will be at a disadvantage2) hybrid, transmissions3) crave, One indication, to distinguishII.
