14．Had he not come an hour earlier，he___the secret that his mother was always there．（　　）
A．must never findB．must never have found
C．would never findD．would never have found

分析 如果他不早來(lái)一個(gè)小時(shí)的話，他就永遠(yuǎn)不會(huì)發(fā)現(xiàn)他媽媽總是在那里的秘密了．

解答 答案：D
根據(jù)題干中Had置于句首可知，此句為省略if的虛擬條件從句．由從句中的謂語(yǔ)動(dòng)詞had come可知，是對(duì)過(guò)去時(shí)間的假設(shè)虛擬，所以主句的謂語(yǔ)動(dòng)詞形式應(yīng)為would/could/might/should have done．故選D．

點(diǎn)評(píng) 虛擬條件從句的謂語(yǔ)動(dòng)詞如果是had、should、were的話，可將連詞if省略，此時(shí)將had、should、were提前句子倒裝．解題時(shí)，先確定是否考查虛擬語(yǔ)氣，再根據(jù)主從句中謂語(yǔ)動(dòng)詞的形式判斷是對(duì)哪一個(gè)時(shí)間的假設(shè)，進(jìn)而做出正確的選擇．判斷標(biāo)準(zhǔn)如下：①對(duì)過(guò)去時(shí)間假設(shè)，if從句中謂語(yǔ)動(dòng)詞為had done，主句謂語(yǔ)動(dòng)詞為would/could/might/should have done②對(duì)現(xiàn)在時(shí)間假設(shè)，if從句中謂語(yǔ)動(dòng)詞為were/did，主句謂語(yǔ)動(dòng)詞為would/could/might/should do③對(duì)將來(lái)時(shí)間假設(shè)，if從句中的謂語(yǔ)動(dòng)詞為were/did；were to do或者should do，主句謂語(yǔ)動(dòng)詞為would/could/might/should do

2．Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger，but we also affect our water supply in less obvious ways．You may wonder how paving（鋪砌） a road can lead to less useable fresh water．A major part of the water we use every day is groundwater．Groundwater does not come from lakes or rivers．It come from underground．The more roads and parking lots we pave，the less water can flow into the ground to become groundwater．
Human activity is not responsible for all water shortages（短缺）．Driver climates are of course more likely to have droughts（干旱） than areas with more rainfall，but in any case，good management can help to make sure there is enough water to meet our basic needs．
Thinking about the way we use water every day can make a big difference，too．In the United States，a family of four can use 1.5tons of water a day!This shows how much we depend on water to live，but there's a lot we can do to lower the number．
You can take steps to save water in your home．To start with，use the same glass for your drinking water all day．Wash it only once a day．Run your dishwasher （洗碗機(jī)）only when it is full．Help your parents fix any leaks in your home．You can even help to keep our water supply clean by recycling batteries instead of throwing them away．

60．Which of the following is most likely to lead to less groundwater？C
A．Using river water．
B．Throwing batteries away．
C．paving parking lots．
D．Throwing rubbish into lakes．
61．What can be inferred from the text？B
A．All water shortages are due to human behavior．
B．It takes a lot of effort to meet our water needs．
C．There is much we can do to reduce family size．
D．The average family in America makes proper use of water．
62．The last paragraph is intended toD．
A．show us how to fix leaks at home 
B．tell us how to run a dishwasher
C．prove what drinking glass is best for us 
D．suggest what we do to save water at home
63．The text is mainly aboutD．
A．Why paving roads reduces our water 
B．how much we depend on water to live
C．why droughts occur more in dry climates
D．how human activity affects our water supply．
