liveinthecountryratherthaninthecity.Suggestedanswers:1.D這些小麥農(nóng)戶什么時候會加入預(yù)試驗仍然不得而知。解析:當(dāng)主語從句中句子成分完整，詢問“時間”時，主語從白用when引導(dǎo)。2.C如何能夠找到一個合適的解決辦法，在保證環(huán)境安全的同時，生產(chǎn)足夠的糧食，是一個需要我們研究的重要課題。解析：主語從句中句子成分完整，詢問“方式”時,主語從句用how引導(dǎo)。3.A令很多人擔(dān)心的是，這些化學(xué)制品甚至可能導(dǎo)致癌癥。解析：主語從句中缺少主語，表示“什么”用what引。4.E令我們所有人驚訝的是，通過這種新技術(shù)，可以無土栽培這些蔬菜。解析：it為形式主語,that引導(dǎo)的從句是句子真正的5.B主語有些人更喜歡住在鄉(xiāng)下而非城市的原因是前者生活節(jié)奏更慢、生活方式更健康。解析：主語從句結(jié)構(gòu)完整且描述的是事實，所以用that引導(dǎo)?；顒尤?，強化訓(xùn)練Readthepassageandunderlineallthesubjectclauses.
