People with bigger brains tend to score higher on standardized tests of intelligence, according to new study findings.
However, Dr. Michael A.McDaniel emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein’s brain was “ not particularly large,” McDaniel noted “ There’s some relationship between brain size and intelligence on average, but there’s plenty of room for exceptions,” he said.
Interest in the relationship between brain size and intelligence grew in the 1830s, when German anantomist(解剖學(xué)家)Frederick Tidemann wrote that he believed there was “ a natural connection between the size of the brain and the mental energy displayed by the individual man.” Since that statement, scientists have conducted numerous studies to determine if Tidemann’s idea was , in fact, correct. Most studies have investigated the link between head size and intelligence .More recently, however, researchers have published additional studies on intelligence and brain size, measure using MRI scans.
For his study, McDaniel analyzed more than 20 studies that investigated the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on average, people with larger brain volume tended to be more intelligent. The relationship was stronger in women that men, and adults than children ,McDaniel noted.
In an interview, McDaniel noted that he’s not sure why the relationship was stronger for adults and women. Previous research has shown that women, on average, tend to have smaller brains that men, but score just as well--- if not higher--- in tests of intelligence he said.
McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-brained people who are highly intelligent,” he said” But , on average, the relationship holds.”
73．What does the passage mainly tell us?
A．The success of using MRI scans for studies on man’s intelligence.
B．On average bigger brains mean higher IQ.
C．The importance of our brain volume.
D．Dr. Michael succeeded in his studies on man’s intelligence.

A．what Albert Einstein achieved had nothing to do with his brain size
B．probably the studies on man’s intelligence are not worth believing
C．why hard working is more important than intelligence.
D．the results of these studies are not true for everyone
75．The underlined word “investigated “ could be replaced by ____.

Several years ago, I read a book Your Money or Your Life, written by Joe Domingguez and Vicki Robin. The major theme of the book is the idea that if you want to cut your spending, you’ll have to begin by stopping trying to impress other people.
The authors divide people into two groups : people whose opinions you care about, and people whose opinions you don’t care about one way or another. It’s easy to stop caring about people whose opinions you don’t care about. Who cares what they think ? As long as you’re not doing something truly immoral —— something that might potentially create a negative reputation for you —— it doesn’t matter what they think.
But shouldn’t you impress other people whose opinions you do care about ? Anyway, they are people you want to meet : customers, friends and family.
The answer is that you don’t need to impress those people with expensive, shiny things. The relationship you’ve built with them —— or you’re going to build with them —— is based on you, not on the material items. They’ll either like you for you or they won’t.
To put it simply, take care of the basics. Keep yourself clean. Keep your weight under control. Wear reasonable clothing. Work on your communication skills. If you have them covered, you don’t need to invest time and money in impressing other people.
Coming to this realization is incredibly valuable. It drops your clothing budget. It drops your automobile budget. It drops your electronics budget. It drops your housing budget. You don’t need a shiny car, an iPhone, or a＄50 haircut.
Yes , you may actually still want one or two of these things, but the impetus(動(dòng)力) comes from what your personal values are, not what other people around you seem to value or what marketing messages you receive.
For some people, it seems impossible. Their social cues come from advertising-laden media and from friends who also get their cues from advertising-laden media.They believe they need a slick cellphone and ＄100 casual clothes. Their self-worth revolves around that little burst they get from impressing others.
People should learn to break through that situation. In short, don’t play socially by the tiring old rules that revolve around needing to impress people. Instead, spend your time on things that bring real value to you and give real value to others.
66. Which of the following behaviours is “immoral”according to the second paragraph ?
A. Caring about other people’s opinion.      B. Dropping your clothing budget.
C. Copying existing works.                 D. Obeying the traffic rule. 67. To build relationship with others, you should pay attention to the following EXEPT _______.
A. dressing casually                       B. learning about weight control
C. improving communication skills           D. being a tidy person
68. As for people we care about, what does the author advise us to do ?
A. To impress them in a proper way.          B. To buy them special gifts.
C. To spare more time to be with them.     D. To impress them with shiny things.
69. Which of the following is TRUE according to the passage ?
A. An iPhone is totally unnecessary in our life.
B. Your family members’opinions are always worth caring about.
C. Learning how to impress others helps people save money.
D. You should always be aware of what other people around you seem to value.
70. What is the best title for the passage ?
A. Whose opinions do you care about ?           B. Two different groups of people.
C. My favorite book : Your Money or Your Life    D. Stop trying to impress other people.

If we really want to be happy, why do we complain all the time in our daily life? We can be active in our life by setting goals and going   34   what we want. But if we’re always expressing complaints, we can not really live   35  .
If you don’t believe me,   36   how many times you complain about something or other in one day. Whether it is being stuck in traffic, being bothered by the weather, or whatever it is, there are endless   37   where you can find a reason to complain. But it’s not just outside circumstances   38   we complain about. We also complain about   39  . We complain constantly that we don’t have enough time, that we don’t have enough money and that we’re not   40   enough, cool enough, or just enough.
Most of us have experienced plenty of unpleasantness   41   complaining about things we can’t control, so do I. And I   42   really thought about it much until I found the website about “l(fā)iving in a complaint-free world”, which   43   my attitude towards life.
Imagine how   44   you would be if you simply stopped being a complainer.   45   of what you complain of is outside of your control anyway.   46  , it is no use thinking about something you have no power to change. When you   47   that you’re complaining, stop and ask yourself if you would rather complain, or be happy.

What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.
(   ) 46. We can infer from the first paragraph that ________.
learning better at school shows power in your job
the better you are at school subjects, the more helpful they are in your career.
learning each subject well is an ability in many jobs.
we should think about how to find our career
(   ) 47. From the passage we learn that if a student’s school performance is not good, he
will _____.
A. have no hope in his future work
B. be hopeful to find a suitable job
C. regret not having worked harder at school
D. have an opportunity of a new beginning in his future work
(   )48. All the subjects may have direct value for job hunting except _________.
A. mathematics     B. English       C. history       D. technical drawing
(   )49. The underlined phrase “be all thumbs” (in Paragraph 3) probably means “_________”.
A. heavy- handed    B. the best      C. important    D. skilled
(   )50. The passage mainly discusses ___________.
A. The relationship between school performance and career
B. how to get a job
C. How to show strengths in your work

Justin’s bedroom was so full of flat bicycle tires, bent tennis rackets, deflated（癟掉的）basketballs, and games with missing pieces that you could barely get in the door. His parents pleaded with him to clean out his room.
“What use is a fish tank with a hole in the bottom?” his father asked. But Justin simply smiled and repeated his motto, “Never throw anything out, you never know when it might come in handy.”
When Justin was away from home, he always carried his blue backpack--a smaller version of his bedroom--a place to store the many objects that he collected. It was so worn and stretched that it hardly resembled a backpack anymore.
Justin had earned a reputation for figuring things out and getting people out of otherwise hopeless situations. Many of his classmates and neighbors sought him out when they needed help with a problem. On the first day of school, his friend Kenny, came looking for Justin.
“Do you think you have something in your bag that could help me remember my locker combination?” he asked. “I lost the piece of paper it was written on. I have a science class in two minutes and if I’m late on the first day it’ll make me look bad for the rest of the year.” Kenny looked really worried.
“Relax,” Justin said, taking his backpack off and unzipping the top. “Remember how you borrowed my notebook in homeroom to write the combination down? Well, I know how we can recover what you wrote.”
He took the notebook and a soft lead pencil out of his bag. The page that Kenny had written on had left faint marks on another page in the notebook. Justin held the pencil on its side and rubbed it lightly over the marks. Slowly but surely the numbers of the locker combination appeared in white, set off by the gray pencil rubbings.
“That’s amazing!” Kenny said. “I owe you one.” And he dashed off to open his locker.
It was just another day in the life of the boy whose motto was “Never throw anything out, you never know when it might come in handy.”
小題1:Why is Justin’s room such a mess?
A．He always forgets to clean it.B．He shares the room with his brother.
C．He has no time to clean it.D．He never throws anything away.
小題2:In what way is Justin’s backpack a smaller version of his bedroom?
A．He uses it as a place to store objects.
B．He uses it to carry his books and sports equipment.
C．His parents tell him to clean it all the time.
D．He’s had it for as long as he can remember.
