12．-Why did you go back to the shop？
-I left my friend ____ there．（　　）
A．waitingB．to waitC．waitedD．wait

分析 -你為什么回到店里？-我讓朋友一直在那等著呢．

解答 答案：A 短語搭配，leave sb doing sth讓某人一直做某事，表達進行；leave sb to do sth留下某人去做某事，表達未發(fā)生．句意表達等的動作在發(fā)生，故選A．

點評 現(xiàn)在分詞是非謂語動詞的一種，表達主動或進行；過去分詞表達被動或完成；動詞不定式表達未發(fā)生的動作．學(xué)習(xí)時，要注意區(qū)分和掌握．

3．If you've ever dashed into the grocery store to pick up a tube of toothpaste，you're  likely to stop before so many options available．There are at least more than a dozen brands，each one presenting several different specialties of cleaning ability．Sometimes before you  have enough time to take the costs，flavors and colors into consideration，you are warned the  store is closing．
But it's not just the number of options that gives us pause for thought-it's the amount of information each option has that trips us up（使某人犯錯）too．Social scientist Barry Schwartz thinks in part that an abundance of choices and information may make us falsely believe that even a fairly ordinary task like shopping for toothpaste has great significance than it really does．He also points out that the Internet can actually make matters worse．
Our goal is to make the"perfect"choice．When we make decisions，we're motivated not only by the opportunity for gain，but also by the fear of loss．The decision-making process isn't a purely analytical one-researchers discovered that the process of making a choice lights up parts of our brains that deal with regret and emotional memories．But what we may regret most is the extra time spent on analyzing and comparing each and every bit of information，which can lower our decision-making ability．
One good approach is to place a value on the time it takes to make your decision，compared to the value of the decision itself．In the case of toothpaste，you probably serve your interest sufficiently by quickly choosing any toothpaste that keeps white teeth securely rooted in your minty（清新的）mouth．
32．We can learn from the first paragraph thatD．
A．more options help people make the right decision
B．different kinds of toothpaste function similarly
C．people's personal preferences affect their choices
D．time is wasted on making insignificant decisions
33．What can we infer from the second paragraph？C
A．People often make wrong decisions．
B．There are no small decisions in 1ife．
C．The Internet provides more options．
D．Careful choice iS worth the effort．
34．In making choices，people have to balanceB．
A．time and place
B．gain and loss
C．regret and memories
D．opportunity and motivation
35．The writer's purpose in writing this text is toA．
A．give advice on how to make a quick and right choice
B．show how valuable time is wasted for nothing
C．describe the choice-making process in our brain
D．offer tipg on how to save time when shopping．
