A.the sense of flying heightC.the distance to the netsB.Differences in the eating habits of bats and birds.D. Another interesting characteristic of bat flight is the way in which bats landupside down! Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force。 （4）考查主旨大意，根據(jù)文章內(nèi)容可知，科學(xué)家改變植物的基因，加快光合作用的速度，使植物葉子生長(zhǎng)迅速，從而提高植物產(chǎn)量。故選B。故選B。Photosynthesis and production【答案】 （1）B（2）B（3）D（4）A 【解析】【分析】本文是一篇說(shuō)明文，科學(xué)家通過(guò)改變植物的基因，加快光合作用的速度，使植物葉子生長(zhǎng)迅速，從而提高植物產(chǎn)量。 living timeB.To help leaves of the plants absorb sunlight.D.They will depend less on sunlight.（2）Why does the author mention lightadjusting glasses？ A.They will have more beautiful flowers.
