A 【文章大意】 本文是一篇說明文,主要介紹了藥用植物供應(yīng)短缺現(xiàn)象和其形成的原因以及如何保護等。 1.D　細節(jié)理解題。根據(jù)第一段最后一句和第二段第二句可知,許多種藥用植物瀕臨滅絕,故選D。 2.A　細節(jié)理解題。根據(jù)第三段第一句“Over-harvesting does the most harm, though pollution and competition from invasive species (入侵物種) and habitat destruction all contribute.”可知,藥用植物供應(yīng)量下降的主要原因是過度采摘,故選A。 3.C　代詞指代題。根據(jù)第三段第二句可知,此處畫線的it指代的是藥用植物的可持續(xù)性,故選C。 4.A　推理判斷題。根據(jù)最后一段最后一句“‘Not nearly enough is being done,’ he told New Scientist. ‘We are destroying the very plants that are of most use to us.’”可推知,保護藥用植物任重而道遠,故選A。 B 【文章大意】 本文是一篇說明文,主要介紹了可以促進環(huán)保的園藝興趣培養(yǎng)。 5.B　詞義猜測題。根據(jù)語境“towards a more meaningful motivation”可推知,此處的channelize意為“轉(zhuǎn)移或開發(fā)新的興趣渠道”,故選B。 6.C　細節(jié)理解題。根據(jù)第三段第四句“…try to store rainwater so that you can use them for gardening…”可知,利用收集的雨水來進行園藝是一種可持續(xù)的環(huán)保方式,故選C。 7.D　推理判斷題。根據(jù)第三段第三句和最后一句可推知,可持續(xù)園藝的好處在于環(huán)保,減少資源的利用或者浪費,故選D。 8.B　推理判斷題。根據(jù)最后一段最后一句“Click here: http:// www. gardenhowto.com.”可推知,本文選材于網(wǎng)絡(luò)內(nèi)容,故選B。 Ⅱ.【文章大意】 本文是一篇記敘文,主要講述了在父親的指導(dǎo)下,作者侍弄園子,并享受勞動成果的故事。 1.was seated　考查動詞的時態(tài)和語態(tài)。固定詞組搭配:be seated意為“落座”,符合語境,且與上文planted呼應(yīng),故用一般過去時的被動語態(tài)。 2.lately　考查詞性轉(zhuǎn)換。lately意為“近來”,與句子的過去完成時呼應(yīng)。 3.better　考查形容詞比較級。與句子中的比較級符號than呼應(yīng)可知,此處用形容詞比較級的形式,作定語。 4.in　考查介詞。in a chocked voice意為“用哽咽的聲音說”,結(jié)合語境可知,此處用介詞in。 5.you　考查代詞。與上文“‘You can give me some tips,’ I replied.”呼應(yīng)可知,此處父親給作者提出了一些建議,故用代詞you。 6.and　考查連詞。根據(jù)語境可知,此處表示幾個動作的連續(xù)進行,故用連詞and,表示并列和順接關(guān)系。 7.the　考查冠詞。air是獨一無二的事物,故用定冠詞修飾。 8.peaches　考查名詞復(fù)數(shù)。peach是可數(shù)名詞,且沒有被冠詞修飾,故用復(fù)數(shù)形式。 9.staring　考查非謂語動詞。stare和句子謂語ate之間沒有連詞,故用非謂語,且和句子主語we構(gòu)成邏輯上的主動關(guān)系,故用現(xiàn)在分詞作伴隨狀語。 10.silent　考查詞性轉(zhuǎn)換。與語境content呼應(yīng)可知,此處用形容詞形式,在句子中作表語。 Ⅲ.In the past two years, our school had organized many activities. What impressed me most was an activity ┬has calling “Learning to Farm”. In an autumn afternoon, we went to the farm, where we learned to plant potatoes. ┬called ┬On ┬a Having been in the city for such a long time, we are so happy to go to the countryside. After we got there, we were ┬were divided into three groups, ∧┬and we started to work. Some students cut potatoes into pieces, some dug hole, and the ┬holes others put the pieces of potatoes into the holes, put the earth back and pushed them down hard. We were all busy ┬it working as all the work was done. Though we were tired out, we felt pleased on our way back to home. ┬(until"/" till)
