29、語從句。相當(dāng)于people say that...的意思。該結(jié)構(gòu)還能夠改變成sb. is said to do...結(jié)構(gòu)。 (2)注意根據(jù)動(dòng)詞不定式和is said動(dòng)作之間的時(shí)間關(guān)系，使用不定式的一般式、實(shí)行式或 完成式。 ①John is said to be one of the best teachers in the school. =It is said that John is one of the best teachers in the school. 據(jù)說約翰是這個(gè)學(xué)校最好的老師之一。 ②He is said to have written a new book a

(P34) 收集和評(píng)估了這些信息之后，我就協(xié)助其他科學(xué)家來預(yù)測(cè)熔巖接著將往何處流去，流速是多 少。 【句法分析】having collected and evaluated the information是現(xiàn)在分詞的完成式在 句中作狀語，表明從句動(dòng)作發(fā)生在主句動(dòng)作之前。 ①Having answered the teacher? s questions, she sa

33、t down and felt much more relaxed. 回答老師的問題后，她坐下來，感到輕松多了。 Having been separated from other continents for millions of years?

34、間存有被動(dòng)關(guān)系，但有時(shí)無被動(dòng)意味，僅僅表示一種狀態(tài) 或動(dòng)作的完成，而現(xiàn)在分詞與主語之間存有著主動(dòng)關(guān)系。 ③Given better attention, the flowers could have grown better. 要是照看得好一點(diǎn)，這些花會(huì)長(zhǎng)得更好。 ④Dressed in white, she looks really pretty. 穿著白衣服，她看起來真美。 ⑤Seeing the photo, he couldn* t help thinking of his good old days.看到那張照片, 他禁不住想起了美好的往昔。 ［即境活用］ 12. in

35、 the queue for half an hour, the old man suddenly realized he had left the cheque in the car. A. Waiting B. To wait C. Having waited D. To have waited 解析：選C。本題考查非謂語動(dòng)詞。根據(jù)the old man與wait之間的關(guān)系，應(yīng)該選擇v. ing形式，再根據(jù)句意得知他是先“wait”后才“realize”。所以先發(fā)生的動(dòng)作應(yīng)該用完成 式 Having waited。 13. there for some time, Mr. John

36、son knew the place quite well. A. Having lived B. Living C. To live D. Lived 解析：選A。考查非謂語動(dòng)詞。Mr. Johnson與live之間構(gòu)成邏輯上的主動(dòng)關(guān)系，“先在那兒 住一段時(shí)間”才能“很熟悉那個(gè)地方”，所以應(yīng)用V. ing形式的完成式作狀語。 3【教材原句】 The other two climbed down into the crater to collect some lava for later study, but this being my first experience, I stay

37、ed at the top and watched them. (P35) 另外兩人攀下火山口去收集供日后研究用的巖漿，我是第一次經(jīng)歷這樣的事，所以留在山頂 上觀察他們。 【句法分析】this being my first experience是獨(dú)立主格結(jié)構(gòu)。 獨(dú)立主格結(jié)構(gòu)的構(gòu)成方法： n. /pron. +v. - ing/- ed/to do/n. /adj. /adv. /prep, phrasea 其中名詞或代詞起著邏輯主語的作用；另一部分表示狀態(tài)、狀況或動(dòng)作。 獨(dú)立主格結(jié)構(gòu)本身不是句子，但在語義上相當(dāng)于一個(gè)句子。在句子中作狀語，表示時(shí)間、原 因、條件、伴隨等。獨(dú)立主格結(jié)構(gòu)

38、一般用逗號(hào)與主句分開。 ①The guide leading the way, we had no trouble getting out of the forest.向?qū)ьI(lǐng) 著路，我們亳不費(fèi)勁地走出了森林。 ②Weather permitting, we will go on an outing to the beach tomorrow.如果天氣允許 的話，我們將在明天組織一次海濱旅游。 ③He left the office, tears in eyes. 他眼里含著淚水離開了辦公室。 ④He walked into the classroom, his head lowere

A. finishing B. finished C. had finished D. were finished 解析：選B。本題考查名詞的獨(dú)立主格結(jié)構(gòu)。名詞短語their lessons和動(dòng)詞finish之間 是被動(dòng)完成關(guān)系，故用

40、過去分詞finished。 ［即境活用］ 15. The car burns more fuel, but all things into consideration^ it s still a good car. A. taken B. having taken C. taking D. to take 解析：選c。獨(dú)立成分作狀語。注意有些分詞短語的形式是固定的，不受上下文影響，所以 被稱為獨(dú)立成分。句意：這輛汽車耗油量較大，但是綜合整體情況來看，它仍不失為一部好 車。 作文指導(dǎo) 說明文 【體裁導(dǎo)航】 說明文，顧名思義，就是要說清、道明?？梢姡逦拿枋?、不紊的條理、分明

41、的層次和準(zhǔn) 確的用詞，都是說明文最明顯的特征。 無論是文字?jǐn)⑹鲞€是圖表標(biāo)識(shí)，只要無時(shí)間限制，說明文中一般都要用現(xiàn)在時(shí)態(tài)。 圖表說明文是近年來高考英語寫作的重點(diǎn)、熱點(diǎn)，也是國(guó)家英語課程標(biāo)準(zhǔn)所要求掌握的。做 這個(gè)寫作題型時(shí)，同學(xué)們最好能在分清圖與圖之間邏輯關(guān)系的基礎(chǔ)上，列出要點(diǎn)，逐條予以 說明。這樣，既能避免主次不分，又能有效防止要點(diǎn)的遺漏。 巧用過渡性詞語，能使文章結(jié)構(gòu)緊湊，條理清晰。 中學(xué)階段常用的過渡詞語主要有以下幾類： 1. 表示時(shí)間順序：first, then, afterwards, to begin with, meanwhile, later, soon, finally

42、 2. 表示空間順序:near, next to, far from, in front of, on the left, on one side 3. 表示并列關(guān)系:and, as well as, also, too … 4?表示因果關(guān)系:because, for, since, as a result (of), therefore, thus, thanks to ... 5 .表示遞進(jìn)關(guān)系：besides, what s more, moreover, furthermore, in addition, also, one more thing 6 . 表示比!奧關(guān)系：li
