この例文ですが、なぜ主節の時制は現在完了でなく、過去形なのでしょうか？

主節の動詞:過去形 (returned) 副詞節の動詞:過去完了形 ( had read) As she had read the book, she returned it to the library. ↓動詞が「過去完了形」 なので...... As she Having read the book, she returned it to the library. (彼女はその本を読み終えたので、図書館へ 返した。)

(A) Electron overflow model (considered out-of-date) Alt UQ pool Alternative oxidase inactive. Alt No alternative pathway activity Cytochrome pathway unsaturated Cyt (B) Electron distribution model (reflects current thinking) UQ pool Cyt Alternative pathway active Cytochrome pathway saturated Alt Alternative oxidase active Alt UQ pool Cyt Cyt Figure 14.33 Two models for regulation of electron flow through the alternative oxidase. (A) In the electron overflow model, no appreciable electron transfer through the alternative pathway takes place until electron flow through the cytochrome pathway is at or near satu- ration. This could result from the effects of respirato- ry control, if the rate of mitochondrial ATP produc- tion exceeds its rate of utilization in the cytosol, or from some externally imposed stress, such as low temperature. Under such circumstances, the UQ pool becomes sufficiently reduced to allow electrons to flow through the alternative oxidase, the latter re- quiring that the UQ pool be 40% to 60% reduced to attain significant activity. (B) In the electron distribu- tion model, the alternative and cytochrome path- ways both show significant activity at low levels of UQ pool reduction, and electrons are distributed be- tween the two pathways on the basis of the relative activities of each pathway. The activity of the alter- native oxidase under these circumstances is thought to be regulated by the action of a-keto acids and by reduction/oxidation of the intermolecular disulfide bond, as well as by additional regulatory mecha- nisms not yet characterized.

e 10 Even in tropical regions, the climate and vegetation of mountains differ considerably from what would be considered normal for the area. Kenya's Mount Kenya, only about ten miles from the Equator, has fifteen glaciers. The windward side of a mountain usually has a much lower temperature and a much heavier rainfall than the leeward side. The leeward side is often known as a "rain way the shadow," and is a desert. Most mountains have what is called a timber line, a line above which no trees grow. Immediately below that line, even in the Torrid Zone where one would expect palm trees and tropical vegetation, the vegetation and trees are more the deciduous types of the Temperate. stupa
