2018年高考英語(yǔ)重難點(diǎn)總結(jié)
現(xiàn)代農(nóng)業(yè)的核心是科學(xué)化,特征是商品化,方向是集約化,目標(biāo)是產(chǎn)業(yè)化。
現(xiàn)代農(nóng)業(yè)是與生態(tài)農(nóng)業(yè)( eco-agriculture ),旅游觀光農(nóng)業(yè)( sight-seeing agriculture ),綠色食品(green food ),無(wú)公害蔬菜( healthy vegetables ),以及可持續(xù)發(fā)展( sustainable development )息息相關(guān)的。
二、疑難詳解。
1. it is on this arable land that the famers produce food for the whole population of china.
農(nóng)民們正是在這些可耕地上為全國(guó)人民生產(chǎn)各種糧食。
[問(wèn)]如何理解這個(gè)句子結(jié)構(gòu)?
[答]這是個(gè)強(qiáng)調(diào)句,,其結(jié)構(gòu)為:it is (was)+被強(qiáng)調(diào)部分+that/who-從句,被強(qiáng)調(diào)部分可以是句子的主語(yǔ)、賓語(yǔ)、狀語(yǔ)等,如果被強(qiáng)調(diào)部分是物,從句用that引導(dǎo),如果指人,則可用that或who來(lái)引導(dǎo)從句。課文第三段還有一個(gè)強(qiáng)調(diào)句。又如:
it was they who (that)helped me in the street this morning. 今天上午就是他們?cè)诮稚蠋土宋摇?br>it was this morning that they helped me in the street. 他們是今天上午在街上幫我的。
who was it that taught them french yesterday? 昨天教他們法語(yǔ)的是誰(shuí)?
what was it that the new teacher taught them yesterday? 昨天新老師教他們的是 什么?
2. to make as much use of the land as possible. two or more crops are planted each year where possible. 為了更充分地利用土地資源,在可能種植兩種或兩種以上作物的地方種植不同的作物。
[問(wèn)]不定式短語(yǔ)為什么放在句首?怎樣理解as possible 和where possible?
[答]不定式作目的狀語(yǔ)可位于句首,起強(qiáng)調(diào)作用,此外i norder to 和so as to 都可引導(dǎo)目的狀語(yǔ),但so as to 不能位于句首。如:
(in order )to pass the exams, he did his lessons till late at night.
為了通過(guò)考試,他復(fù)習(xí)功課直到深夜。
此句可改為:he did his lessons till late at night so as to pass the exam. 句中的make use of 是一個(gè)短語(yǔ),意為:“利用、使用”,如:
we should make full use of time in our study. 我們?cè)趯W(xué)習(xí)中應(yīng)充分利用時(shí)間。
it is very important for us to make good use of water. 好好利用水資源是很重要的。
句中的as much ... as possible 意為:“盡可能多地……”, much 后接不可數(shù)名詞,若為可數(shù)名詞,則用many來(lái)修飾。又如:
please give him as muvh help as possible. 請(qǐng)盡可能多地買(mǎi)了書(shū)。
句中的where possible 是一種省略形式,在句中作地點(diǎn)狀語(yǔ),相當(dāng)于where it is possible ,連詞if,when, while, until等都可用于這種省略句。例如:
i will pay you a visit when (i am)free. 我有空時(shí)會(huì)來(lái)看你的。
tell the manager immediately about it if (it is )necessary. 如有必要,迅速把這事兒告訴經(jīng)理。
3. this saves time and allows famers to grow an extra crop in each season. 這就節(jié)約了時(shí)間允許農(nóng)民可以在每個(gè)季節(jié)里種植一種額外的作物。
[問(wèn)]allow 和let的含義和用法有什么不同?
[答]二者均可作“允許”解,但各有側(cè)重;allow重在“允許”或“容許”,也可表示客氣的請(qǐng)求,常用于allow sb. to do sth. 或allow doing sth. 結(jié)構(gòu)中。例如:
