2．It is the duty of a teacher _____ the interest of students and pass on knowledge to them．（　�。�
A．to be stimulatingB．to have stimulated
C．to be stimulatedD．to stimulate

分析 激發(fā)學(xué)生的興趣，傳授他們知識(shí)是教師的天職．

解答 答案：D
題干中it是形式主語，正在的主語是后面的動(dòng)詞不定式；stimulate后接賓語interest，是主動(dòng)關(guān)系；句意表達(dá)的是客觀事實(shí)，要不定式的簡單式即可．故選D．

點(diǎn)評(píng) 動(dòng)詞不定式是非謂語動(dòng)詞是一種，表示未發(fā)生的動(dòng)作，用法較多．常用來作定語，主語，賓語，補(bǔ)語，狀語等．本題中不定式用來作主語．

3．Mathilda，15，is Turkana，a native people that has survived by raising cattle in a semiarid （半干旱） region．Mathilda's school，like most schools in the area，doesn't have access to clean water and sanitation facilities for its students．So instead of spending their whole school day learning，Mathilda and her classmates start their day by spending two hours to the closest river fetching water---water that is anyway most likely not safe to drink．They do the same thing again in the afternoon，so they often lose around half of their school day fetching water．
Mathilda has to do the same thing outside of school hours to get the water her family needs at home，leaving her little time for studying．Because of rising temperatures，water has become harder and harder to find here，and people have to spend more and more time trying to find it．
This is just one small example of how climate change is making it harder to realize people's rights to water，education and security．Unfortunately，most higher-income countries remained silent on the issue．
This is despite studies showing that communities already facing marginalization（邊緣化），such as women and children，mostly suffer from climate change．This is especially the case for those in countries with limited resources and fragile ecosystems．
Meanwhile，women consist of the majority of the world's poor，and so are more dependent for their livelihood on natural resources that are threatened by climate change．And around the world，women and girls are the most likely to be responsible for fetching water for their families．
This exposes them to danger and leaves them with less time to attend school，earn money，or simply to rest．But the fact is that the effects of climate change will be felt globally．
Despite the difficulties she is facing，trying to get an education，Mathilda says she hopes to serve her community in a leadership role when she grows up．
"All of the world's leaders need to work together to solve this problem that we are all facing，"she said．
24．Mathilda has to spendCfetching water every school day．
A．two hours  
B．four hours   
C．more than four hours    
D．a(chǎn)lmost a whole day
25．The first two paragraphs are intended to tell usB．
A．the cause and effect of lack of water  
B．one serious consequence of climate change
C．the difficulties in fetching water in the semiarid region
D．the hardship of life for the people in the semiarid region
26．We can conclude from the passage thatA．
A．climate change is everyone's business
B．water is becoming rare because of rising temperatures
C．fetching water takes up Mathilda's half of studying time
D．females are more responsible for fetching water for their families
27．The passage is mainly about the problem caused byC．
A．rising temperatures       
B．fetching water

20．However wealthy we may be，we can never find enough hours in the day to do everything we want．Economics deals with this problem through the concept of opportunity cost，which simply refers to whether someone's time or money could be better spent on something else．
Every hour of our time has a value．For every hour we work at one job we could quite easily be doing another，or be sleeping or watching a film．Each of these options has a different opportunity cost-namely，what they cost us in missed opportunities．
Say you intend to watch a football match but the tickets are expensive and it will take you a couple of hours to get to and from the stadium．Why not，you might reason，watch the game from home and use the leftover money and time to have dinner with friends？This-the alternative use of your cash and time-is the opportunity cost．
For economists，every decision is made by knowledge of what one must forgo-in terms of money and enjoyment-in order to take it up．By knowing precisely what you are receiving and what you are missing out on，you ought to be able to make better-informed，more reasonable decisions．Consider that most famous economic rule of all：there's no such thing as a free lunch．Even if someone offers to take you out to lunch for free，the time you will spend in the restaurant still costs you something in terms of forgone opportunities．
Some people find the idea of opportunity cost extremely discouraging：imagine spending your entire life calculating whether your time would be better spent elsewhere doing something more profitable or enjoyable．Yet，in a sense it's human nature to do precisely that-we assess the advantages and disadvantages of decisions all the time．
In the business world，a popular phrase is"value for money．"People want their cash to go as far as possible．However，another is fast obtaining an advantage："value for time．"The biggest restriction on our resources is the number of hours we can devote to something，so we look to maximize the return we get on our investment of time．By reading this passage you are giving over a bit of your time which could be spent doing other activities，such as sleeping and eating．In return，however，this passage will help you to think like an economist，closely considering the opportunity cost of each of your decisions．

58．According to the passage，the concept of"opportunity cost"is applied toD．
A．making more money 
B．taking more opportunities
C．reducing missed opportunities 
D．weighing the choice of opportunities
59．The"leftover…time"in Paragraph 3probably refers to the timeC．
A．spared for watching the match at home 
B．taken to have dinner with friends
C．spent on the way to and from the match 
D．saved from not going to watch the match
60．What are forgone opportunitiesB？
A．Opportunities you forget in decision-making．
B．Opportunities you give up for better ones．
C．Opportunities you miss accidentally．
D．Opportunities you make up for．
