2．Because of the strong curiosity，they exploredthe land the moment they arrived．

分析 因為強烈的好奇心，他們一到達就開始對這塊土地進行探測．

解答 答案：explored 考查首字母填空．根據(jù)句意和句子結(jié)構(gòu)，要填入動詞，explore意為"探測；探險"因從句the moment they arrived用了一般過去時，主句也應(yīng)用一般過去時．

13．A．Come in with something to say．
B．Prepare general comments．
C．Bring materials with you．
D．Don't make them wait．
E．Have no fear．
F．Go it alone．
   One of the best things you can do any time in the semester is go see the professor．So hoof on over to an office hour and have some one-on-one face time with someone who'll help you master the material and improve your grade，to boot．But how should you have this conversation with the professor？Here are five insider tips about how to make that office hour really count：．
56．ENo need to get all bent out of shape about going to see the professor．The professor would actually like to see you and answer your questions．Believe it or not，he or she is on your side and is eager to see you do well．And besides，he or she has seen many students stupider than you，so nothing you're going to ask will set the record for stupidity．
57．FEven though you might feel more comfortable going with a friend or partner，the office hour will go better if it's just you and the professor．You'll get in more questions，the discussion will be tailored to what you need most help on，and two-party communication is almost always more productive than committee work．Your friend can wait outside for the discussion．
58．DIf you can't make the official office hours，most professors are willing to make individual appointments to help you out．If you're lucky enough to land such an accommodation，though，be sure you're 100 percent on time．There's nothing that ticks off a professor more than making him-or herself available for a custom office hour only to find that you don't care enough to come on time．And besides，the professor might leave after ten minutes，which would make your trip a total loss．
59．CIf you're meeting with the professor to go over a paper or test，or to ask questions about a particular lecture or reading，make sure you bring that paper or test，or your lecture notes or a copy of the article．The professor doesn't remember the comments he or she wrote on your individual piece of work---though he or she will be able to recall them after just a brief glance at your work．And if you have your lecture notes or the article in hand，you and the professor will be able to examine specific points that are confusing to you，rather than just talking in a general way about the contents．
60．AOffice hours almost always go better if you bring a few specific questions to the meeting．It's almost never good to start a meeting with general comments such as"I didn't understand what you said about[main topic of the course]"or"I couldn't understand any of your lectures last week．"Much better is to come in with two or three conversation-starters about a specific concept，point，or problem you didn't understand．Keep in mind that in a fifteen-minute office hour （which is how long these things usually last），two or three questions are usually the most you'll have time to discuss．

17．There is one holiday in the year which is completely American，Thanksgiving Day．It is the day when everyone goes back home to spend the day with his family，to have the traditional Thanksgiving dinner of roast turkey，to talk about old times．
This is a story of Thanksgiving Day and of one man's efforts，under rather special circumstances，to carry on these traditions．
Old Pete took his seat this day on his usual bench in Union Square．Every Thanksgiving Day for nine years，Pete had taken this same seat exactly at one o'clock，and each time the same pleasant thing had happened．But this time Pete had come here more from habit than from hunger．
Certainly today Pete was not hungry．He had just had a dinner so enormous that he could hardly breathe．The buttons on his ragged shirt and coat were about to burst．He was so full of soup，oysters，roast turkey，apple pie，ice cream，and a dozen other rich foods that the November breeze and the first light fall of snow felt cool and pleasant to his face．
The meal had been completely unexpected．He had been passing one of the large homes on Fifth Avenue，where there lived two rich old ladies．It seems that it was their custom each Thanksgiving to place a servant at the front entrance with orders to bring in the first hungry looking person that passed and then give him a Thanksgiving dinner of everything he could eat．On this particular Thanksgiving Day，Pete had passed，the servant had brought him in，and，before Pete knew it，he was being served like a king with more food than he could eat．
Pete sat on the bench now，hardly able to move．He happened to look to the left and there in the distance he saw the Old Gentleman coming toward him．He wanted to get up and run，but he was so full of food that he stayed right there．Every Thanksgiving Day for nine years，the Old Gentleman had come here，and found Pete on this same bench，and then taken him to a restaurant and bought him a Thanksgiving dinner．It was a kind of tradition which the Old Gentleman，who had no family and lived alone，had tried to continue．The old man was tall and thin and sixty years old．He was aristocratic looking and he always dressed in black．His hair was whiter and thinner than it had been the year before，and he leaned more heavily on his cane than he used to．
"How do you do!"said the Old Gentleman．"I am glad to see that the changes of another year have permitted you to move in health through this beautiful world．"
Each time the Old Gentleman had said exactly this same thing．It was part of the tradition．Old Pete，too，began to feel as though he himself was now a part of the tradition，and he therefore did not have the courage to tell the old man that he had already eaten．This dinner seemed to mean so much to the Old Gentleman．
"Thank you，sir，"said Old Pete at last．"I'll go with you gladly．I'm very hungry sir．"
Together the Old Gentleman and Pete walked south to the same restaurant where each year Pete had his Thanksgiving dinner．They sat at the same table．The Old Gentleman seemed pleased and happy．When the waiter brought dish after dish of food to Pete，the Old Gentleman sat quietly and smiled．Under the circumstance，Pete had to eat．It was part of the tradition，and so he ate like a hero．Soup，oysters，roast turkey，pie，he ate everything，although when he entered the restaurant even the smell of more food almost made him sick．At last Pete leaned back with the battle won．
"Thank you sir，"he said，with some effort，"for a fine dinner．"
They parted as they did each year at the door，the Old Gentleman going south，Pete north．
Around the corner，Pete stopped for a moment，felt a terrible pain in his stomach，then fell to the sidewalk unconscious．A little later an ambulance came．In the hospital they discovered that he had had an attack of indigestion．
An hour later，another ambulance brought the Old Gentleman to the same hospital．At first they thought it was also indigestion but later one of the nurses said，
"That nice old gentleman over there--you wouldn't think that it was a case of starvation．Proud old family，I suppose．He told me that he hadn't eaten a thing for three days．"
58．This year Old Pete came to the Union Square becauseD．
A．he was hungry and expected to find some food
B．he had nowhere to go on the Thanksgiving Day
C．he wanted to meet the Old Gentleman and check his health
D．it was a convention for him to accept the Old Gentleman's dinner
59．Why didn't Old Pete refuse the invitation from the Old Gentleman？B
A．Because he felt he had more room for food．
B．Because he realized he was involved in the tradition．
C．Because he felt moved by the Old Gentlemen's generosity．
D．Because he didn't dare to tell the old man he had already eaten．
60．According to the passage，which of the following is true？C
A．Only the Old Gentlemen observed Thanksgiving Day traditions．
B．The two gentlemen were both hospitalized because of hunger．
C．The Thanksgiving dinner offered by the Old Gentleman is more than dinner itself．
D．The food in the restaurant tastes better than that in large homes on Fifth Avenue．
61．What can we learn from the two Thanksgiving Day Gentlemen？B
A．One man's meat is another man's poison．
B．They are really gentlemen true to their word．
C．They are too vain to express their true feelings．

12．Memory，they say，is a matter of practice and exercise．If you have the wish and really make a conscious effort，then you can quite easily improve your ability to remember things．But even if you are successful，there are times when your memory seems to play tricks on you．
Sometimes you remember things that really did not happen．One morning last week，for example，I got up and found that I had left the front door unlocked all night，yet I clearly remember locking it carefully the night before．
Memory"tricks"work the other way as well．Once in a while you remember not doing something and then find out that you did．One day last month，for example，I was sitting in a barbershop waiting for my turn to get a haircut，and suddenly I realized that I had got a haircut two days before at the barbershop across the street from my office．
We always seem to find something funny and amusing in incidents caused by people's forgetfulness or absent-mindedness．Stories about absent-minded professors have been told for years，and we never get tired of hearing new ones．Unfortunately，however，absent-mindedness is not always funny．There are times when"tricks"of our memory can cause us great trouble．

32．If you want to have a good memory，you shouldB．
A．force yourself to remember things
B．make a conscious effort of practice and exercise
C．never stop learning
D．try hard to remember things
33．Which of the following statements is TRUE according to the passage？A
A．One night the writer forgot to lock the front door．
B．One night the writer forgot having locked the front door．
C．The writer remembered to lock the door．
D．The writer remembered unlocking the front door．
34．What can we infer from the last paragraph？A
A．Absent-mindedness stories can bring people fun．
B．Absent-mindedness is more troublesome than forgetfulness．
C．Absent-minded professors are often amused by the incidents，too．
D．Absent-mindedness happens not only to professors but to all other people．
35．Which of the following could be the best title for this passage？B
A．The Key to a Good Memory 　　　　 
B．"Tricks"of Memory
C．The Dangers of Forgetfulness 　   　
D．The Dangers of Absent-mindedness．
