【正文】 spiration, leaving trees in danger of fatally overheating. Because it is difficult for scientists to control and vary trees39。 Ecologist John Drake of the . College of Environmental Science and Forestry and his colleagues grew a dozen Parramatta red gum (Eucalyptus parramattensis) trees in large, climatecontrolled plastic pods that separated the trees from the surrounding forest for a year in Richmond, Australia. Six of the trees were grown at surrounding air temperatures and six at temperatures three degrees Celsius higher. The researchers withheld (扣留) water from the surface soil of all 12 trees for a month to imitate a mild dry spell, then induced a fourday “extreme” heat wave: They raised the maximum temperatures in half of the pods（three with surrounding temperatures and three of the warmer ones）— to 44 degrees ℃. surprise, these trees continued to transpire at closetonormal levels, effectively cooling themselves and their surroundings. The trees grown in warmer conditions coped just as well as the others, and photosynthesis rates bounced back to normal after the heat wave passed, Drake and his colleagues reported online in Global Change Biology. Other scientists call the finding encouraging. “It39。By releasing water.By blocking sunlight.C.D.They grew all the trees in artificial temperatures.They induced a heat wave in a dozen pods of trees.C.D. conditions in their natural environment.（3）The underlined phrase “ground to a near halt” in Paragraph 4 means “________”.

But if a heat wave and a severe drought （干旱）were to hit at the same time and the groundwater was exhausted, the trees may not be so lucky, Drake says.”可知，這些樹(shù)擅長(zhǎng)吸取地下水，如果熱浪干旱同時(shí)發(fā)生，地下水枯竭的話，那么這些樹(shù)生存的可能性就比較小了。故選D。7．閱讀理解s class had studied bees for three days, so he was ready.

Many of them even want to bee president. As we all know, school work is important. But parents should realize that the social skills their children learn from natural conversations with each other are as important as schoolwork and the skills they will need in the future work.
