10．Admitting he is naturally clever，we do not think he will make much improvement， he pays no attention to his lessons．（　　）

A．

so that

B．

as

C．

even if

D．

unless

分析他的确天资聪明，但我们认为他不会有多大进步，因为他不用心学习．

解答答案：B
句意表达的是原因；so that为了，as因为，even if即使，unless除非．根据句意，用as引导原因状语从句．故选B．

点评从属连词是连词的一种，用来引导名词性从句和状语从句．大致可分为三大类：that（无词义，不做成分）if，whether （表达是否的意义，但不做句子成分）；连接代词：who，whom，whose，what，which，whatever，whoever，whichever（有词义，在句子中可作主语、表语、宾语）；连接副词：when，where，why，how，how many，how long，how far，however，whenever，wherever （有词义，作从句的状语）．学习时，要注意区分和掌握．

5．People believe that climbing can do good to health．Where can you learn the skills of climbing then？If you think that you have to go to the mountains to learn how to climb，you're wrong．Many Americans are learning to climb in city gyms （体育馆）．Here，people are learning on special climbing walls．The climbing wall goes straight up and has small holding places for hands and feet．
   How do people climb the wall？To climb，you need special shoes and a harness （保护带） around your chest to hold you．There are ropes （绳索） tied to your harness．The ropes hold you in place so that you don't fall．A beginner's wall is usually about 15 feet high，and you climb straight up．There are small pieces of metal that stick out for you to stand on and hold on to．Sometimes it's easy to see the next piece of metal．Sometimes，it's not．The most difficult part is to control your fear．It's normal for humans to be afraid of falling，so it's difficult not to feel fear．But when you move away from the wall，the harness and the ropes hold you，and you begin to feel safe．You move slowly until you reach the top．
    Climbing attracts people because it's good exercise for almost everyone．You use your whole body，especially your arms and legs．This sport gives your body a complete workout．When you climb，both your mind and your body can become stronger．

15．Lindsay Renwick，the mayor of Deniliquin，a country town in New South Wales，misses the constant whir （嗡嗡声） of the rice mill whose giant fans dried the rice．The Deniliquin mill，the largest rice mill in the Southern Hemisphere （南半球），once processed enough grain to meet the needs of 20million people globally．But six years of drought have had a destructive effect，reducing Australia's rice crop by 98percent and leading to the mothballing of the mill last December．
Drought affects every agriculture industry based in Australia，not just rice-from sheep farming，the country's other backbone，to the cultivation of grapes for wine，the fastest-growing crop there，with that expansion often coming at the expense of rice．The drought's effect on rice has produced the greatest impact on the rest of the world，so far．It is one factor contributing to skyrocketing prices，and many scientists believe it is among the earliest signs that a warming planet is starting to affect food production．
Researchers are looking for solutions to global rice shortages-for example，rice that blooms earlier in the day，when it is cooler，to fight against global warming．Rice plants that happen to bloom on hot days are less likely to produce grains of rice，a difficulty that is already starting to emerge in inland areas of China and other Asian countries as temperatures begin to climb．"There will be problems very soon unless we have new varieties of rice in place，"said Reiner Wassmann，climate change director at the International Rice Research Institute （IRRI）．The recent reports on climate change carried a warning that could make the news even worse：that existing models for the effects of climate change on agriculture did not yet include newer findings that global warming could reduce rainfall and make it more variable．
Yet the effects of climate change are not uniformly bad for rice．Rising concentrations （浓度） of carbon dioxide，the main greenhouse gas，can actually help rice-although the effect reduces or disappears if the plants face unnecessary heat，inadequate water，severe pollution or other stresses．Still，the flexibility of farmers here has persuaded some climate experts that，particularly in developed countries，the effects of climate change may be relieved，if not completely avoided．"I'm not as negative as most people，"said Will Steffen，director of the Fenner School of Environment and Society at Australian National University．"Farmers are learning how to do things differently．"
Meanwhile，changes like the use of water to grow wine grapes instead of rice carry their own costs，as the developing world is discovering．"Rice is an essential food，"said Graeme Haley，the general manager of the town of Deniliquin．"Wine is not．"
