11．At this moment，they see a penniless young manwandering（漫步）on the pavement outside their house．

8．Here is an astonishing and significant fact：Mental work alone can't make us tired．It sounds absurd．But a few years ago，scientists tried to find out how long the human brain could labor without reaching a stage of fatigue （疲劳）．To the amazement of these scientists，they discovered that blood passing through the brain，when it is active，shows no fatigue at all!If we took a drop of blood from a day laborer，we would find it full of fatigue toxins（毒素） and fatigue products．But if we took blood from the brain of an Albert Einstein，it would show no fatigue toxins at the end of the day．
So far as the brain is concerned，it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning．The brain is totally tireless．So what makes us tired？
Some scientists declare that most of our fatigue comes from our mental and emotional（情绪的） attitudes．One of England's most outstanding scientists，J．A．Hadfield，says，"The greater part of the fatigue from which we suffer is of mental origin．In fact，fatigue of purely physical origin is rare．"Dr．Brill，a famous American scientist，goes even further．He declares，"One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems．"
What kinds of emotions make sitting workers tired？Joy？Satisfaction？No!A feeling of being bored，anger，anxiety，tenseness，worry，a feeling of not being appreciated---those are the emotions that tire sitting workers．Hard work by itself seldom causes fatigue．We get tired because our emotions produce nervousness in the body．
32．What surprised the scientists a few years ago？C
A．Fatigue toxins could hardly be found in a laborer's blood．
B．Albert Einstein didn't feel worn out after a day's work．
C．The brain could work for many hours without fatigue．
D．A mental worker's blood was filled with fatigue toxins．
33．According to the author，which of the following can make sitting workers tired？B
A．Challenging mental work．
B．Unpleasant emotions．
C．Endless tasks．
D．Physical labor．
34．What's the author's attitude towards the scientists'idea？A
A．He agrees with them．
B．He doubts them．
C．He argues against them．
D．He hesitates to accept them．
35．We can infer from the passage that in order to stay energetic，sitting workers need toB．
A．have some good food．
B．enjoy their work
C．exercise regularly
D．discover fatigue toxins．

5．Tips for Cooking on a Tight Schedule
From my experience，there are three main reasons why people don't cook more often：ability，money and time，（36）BMoney is a topic I'll save for another day．So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen．Here are three tips for great cooking on a tight schedule：
Think ahead．The moments when I think cooking is a pain are when I'm already hungry and there is nothing ready to eat．So think about of the coming week．When will you have time to cook？Do you have the right materials ready？（37）GMake your time worth it．When you do find time to cook a meal，make the most of it and save yourself time later on．Are you making one loaf of bread？（38）CIt takes around the same amount of time to make more of something．So save yourself the effort for a future meal．
（39）AThis may surprise you，but one of the best tools for making cooking worth your time is experimentation．It gives you the chance to hit upon new ideas and recipes that can work well with your appetite and schedule．The more you learn and the more you try，the more ability you have to take control of your food and your schedule．
Hopefully that gives you a good start．（40）Fand don't let a busy schedule discourage you from making some great changes in the way you eat and live!

A．Try new things．
B．Ability is easily improved．
C．Make three or four instead．
D．Understand your food better．
E．Cooking is a burden for many people．
F．Let cooking and living simply be a joy rather than a burden．
G．A little time planning ahead can save a lot of work later on．

12．Welcome to your future life!You get up in the morning and look into the mirror．Your face is firm and young-looking．
In 2035，medical technology is better than ever．Many people your age could live to be 150，so at 40，you're not old at all．And your parents just had an anti-aging（抗衰老的） treatment．Now，all three of you look the same age!
You say to your shirt，"Turn red．"It changes from blue to red．In 2035，"smart clothes"contain particles（粒子） much smaller than the cells in your body．The particles can be programmed to change clothes'color or pattern．
You walk into the kitchen．You pick up the milk，but a voice says，"You shouldn't drink that!"Your fridge has read the chip （芯片） that contains information about the milk，and it knows the milk is old．In 2035，every article of food in the grocery store has such a chip．
It's time to go to work．In 2035，cars drive themselves．Just tell your"smart car"where to go．On the way，you can call a friend using your jacket sleeve．Such"smart technology"is all around you．
So will all these things come true？"For new technology to succeed，"says scientist Andrew Zolli，"it has to be so much better that it replaces what we have already．"The Internet is one example---what will be the next？

9．Last summer，my friend and I hired a car and headed for Toronto．We didn't book a hotel room （61）because/as/since/for it was at the beginning of September and we thought it would be easy for us（62）to find（find） a hotel．
We （63）had driven/had been driving（drive） for six hours when the weather changed and it looked as if a thunderstorm was coming．We got lost and both were （64）exhausted（exhaust） when I saw an old lady parking her car．I stopped and asked （65）whether/if she knew a hotel nearby．She said there was a hotel down the road，（66）but it might have been closed．The lovely old lady looked at me and said，"Why don't you girls just stay the night at （67）my house？I'll cook for you．"
We ended up going to a little island in Lake Muskoka，（68）whereher family lived．We slept in the （69）comfortable （comfort） beds they built for their kids，and they cooked for us．We stayed at their house for three nights in all and also met their friends．Those days were the （70）best（good） part of our three-week trip!We were glad that we got lost and met the old lady．

10．We have met the enemy，and he is ours．We bought him at a pet shop．When monkey-pox，a disease usually found in the African rain forest，suddenly turns up in children in the American Midwest，it's hard not to wonder if the disease that comes from foreign animals is homing in on human beings．"Most of the infections（感染） we think of as human infections staned in other animals，"says Stephen Morse，director of the Center for Public Health Preparedness at Columbia University．
It's not just that we're going to where the animals are；we're also bringing them closer to us．Popular foreign pets have brought a whole new disease to this country．A strange illness killed Isaksen's pets，and she now thinks that keeping foreign pets is a bad idea．"I don't think it's fair to have them as pets when we have such a limited knowledge of them，"says Isaksen．
"Laws allowing these animals to be brought in from deep forest areas without stricter control need changing，"says Peter Schantz．Monkey-pox may be the wake-up call．Researchers believe infected animals may infect their owners．We know very little about these new diseases． A new bug（病毒） may be kind at first．But it may develop into something harmful，（有害的）． Monkey-pox doesn't look a major infectious disease．But it is not．impossible to pass the disease from person to person．
