Her grandfather devoted his whole life to making life better for others and was killed by Nazi
soldiers in 1944. She was there when the soldiers took her grandfather’s life：“I hid under a pile of leaves．But．you know．I heard it．”
She struggled to work through her anger and hate．but it was necessary for her own survival and self-respect．After the war，she married Jesse Reichek，an American soldier in France，and they eventually settled in the Bay Area,where he grew to become art artist．They came to Petaluma from Berkeley when he needed more room to paint They built their own home and treasured their time together．
Reichek’s years of volunteer work began with caring for an old lady in Sonoma County which made her sensitive to the fact that many older people were living in bad places．So Reichek created Petaluma’s first senior center．Then she noticed homeless people．With Mary Isaac，she co-founded COTS 15 years ago．
These days，she is busier than ever，helping Latino immigrant families and visiting seniors in nursing homes．“Our goal is to promote and educate people in understanding and tolerance(忍受)．
We mllst leam to understand and celebrate our differences”，said event chairman Harry Troutt，who serves on the commission．

website．The book will hit stores in
the U．S．a(chǎn)nd U K．on June 21 and will arrive in
School Soldiers
Russian schoel students will have to do basic military training(軍訓(xùn))in their final year of school，the government has decided．The lesson will include learning to fire guns，marching drills and how to deal with a chemical．nuclear or biological attack．The activity is seen as part of a drive toward the education of their love for their country．
Is it hard for you to get up early and get ready for classes?Some students at Winter Park High
School just roll out of bed in their pajamas(睡衣)and go to class in their own bedrooms．Of course,their teachers and classmates do not see them because all their class work is on the computer．The Florida High School，the state’s only online school，has 250 students who are taking classes at home by computer．Students in this first online program take classes in algebra(代數(shù))，American government，chemistry，computer，economics，and web-page design．They also have to go to regular school to attend other classes．

Dogs are social animals and without proper training，they will behave like wild animals．They will spoil your house，destroy your belongings，bark crazily，fight other dogs and even bite you．
Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing．The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the home setting．
One of the best things you can do for your dog and yourself is to train it．Obedience training(馴服)doesn"t solve all behavior problems，but it is the foundation for solving just about any problem．Training opens up a door of communication between you and your dog．Effective communication is necessary to instruct your dog about what you want it to do．
Training is also all easy way to establish the social rank order．When your dog obeys a simple request of“come here，sit，”it is showing obedience and respect for you．It is not necessary to establish yourself as top dog or leader of the dog pack(群)by using extreme measures．You can teach your dog its subordinate(從屬的)role by teaching it to show submission to you．Most dogs love performing tricks for you to pleasantly accept that you are in charge．
Training should be fun and rewarding for you and your dog。It can enrich your relationship and make living together more enjoyable．A well-trained dog is more confident and can more safely be allowed a greater anlount of freedom than an untrained animal．
64．The author wrote the passage in order to ．
A．teach people how to train the dog．
B．remind people to give their dogs some proper training
C．wain people to avoid the wild dogs．
D．tell the differences between well-trained dogs and untrained ones．
65．What is the main idea of the second paragraph?
A．Obedience training can make your dog obey your orders．
B．You should use effective methods to train your dogs．
C．Obedience training is essential to the dogs though it can’t solve all behavior problems．
D．Effective communication is a must for your dogs．
66．A well-trained dog ．
A．can understand whatever you want it to do
B．a(chǎn)ccept that you are in charge and show obedience and respect for you
C．can make you more confident
D．will affect your social relationship
67．The author explains his idea mainly by ．
A．giving examples B．listing data C．stating facts D answering questions

“Placebo”is a Latin word. It means“I shall please．”And，sometimes。it iust might．
When scientists want to test a new drug．they usually divide a large number of people into two gmups．One group takes the medicine；the other takes a substance(物質(zhì))known as a placebo. It may contain nothing more than sugar．The people do not know which Pill they are taking―the active
one or the inactive one．In this kind of experiment，the medicine must perform better than the placebo to proe it is effective．
Yet people who take a placebo sometimes experience improvements in their health．This is known as the“placebo effect”，the effect of something that is not supposed to have any effect．Some doctors even use the placebo effect in their treatments．They might tell patients that a new drug will srop their. The patient does not know that the pills are inactive. The patient takes the pills and later tells the doctor that the pain is gone．
Now，research in Sweden suggests that placebo treatrnents can also reduce the emotional(情感的)effects of unpleasant experiences．The effects in the brain were similar to those seen when placebos have been used to ease(消除)pain．The researchers say that in both cases，expectations of improvement are a maior influence on the effectiveness of placebos．
Predrag Petrovic of the Karolinska Institute in Stockholm led the study．The findings appeared in the publication Neuron
An influential study on placebos appeared in nineteen fifty-five. It said treatment with a placebo made patients feel better thirty-five percent of the time. But in two thousand-one, Danish researchers reported that they had examimed more than one hundred studies. They found little evidence of healing(治愈)as a result of placebos.
68．Why is“a placebo”used in the experiment?
A．To test which medicine is active and which is inactive．
B．To compare a new drug to an existing drug．
C．To prove how active the“placebo eflfect”is．
D．To decide the effectiveness of a rnedicinal drug．
69．According to research in Sweden，the placebo can reduce the patient’s pain mainly because
A．the pill is very effective B．the pill can pleasethem
C．they expect the improvement greatly D．they believe in the doctors
70．The figure“nineteen fifty-five”(in Paragraph 6)is probably ．
A．the page of a magazine in
B．the number of patients involved in the experiment
C．the year when the findings were published
D．the time when Predrag Petrovic and his team tried their experiment
71．What would be the best title for this passage?
A ．The P1acebo Efiect
B．A
New Research in
C．A New Medicine Was Found D．Active or Inactive?

People in Britain often talk about their homes：their mortgages(按揭)，the interest rates，and rising prices．Here’s a guide to some of the words and phrases you might come across．
It’s a good idea in the UK to arrange a mortgage with a bank before you start looking .This is when the bank tells you how much money they will lend you so you have a good ides of how much you can afford
The next step is to go to an estate agent （房地產(chǎn)代理）and see what sort of properties they have available in your budget range and in your area. If you see something you like, the estate agent
will arrange for you to view the property, so that you can see the house or flat for yourself.
If you see something that takes your eye, you put in an offer. The vendor(賣家)can accept or decline this offer, and if the vendor accepts it , you can move forward with the sale. However, as you don’t pay any money at this point, the offer isn’t legally binding(具有約束力),and in theory , you can pull out of the offer at any time that you like.
Your next step will probably be to get a structrual survey done. A qualified surveyor will inspect the house and write a report that illustrates(闡明) any structrual problems, like damp or drainage problems.
If you still want to go ahead with the sale, you need to appoint a lawyer ot do the legal paperwork, If you already own a house, you might also be busy trying ot sell it . Many house owners prefer to sell to first-time buyers (those people who don’t already own a home),as they are not in a chain(waiting for other people to buy a house before they can buy their next house).
Finally, once the contracts are signed and exchanged, you complete on your house. Your get the keys and you can move in whenever you want. Then you might want to throw a house-warming party . Congratulations!
72． Which of the following shows the right order of what happens
before the people in the
move into a new house?
a．Ask for a company which represents others of propertles．
b．Decide how much to borrow from the bank．
c．Examine the structure of the house
d．Hire a lawyer and make a contract．
e．Offer the seller the right money．
f．Visit the house and discuss a price with the seller．
A．b，a，f，c，d，e B．b，a，f，e，d，c
C．b，a，f，d，c，e D．b，f，d，e，c，a
73．According to the passage，these statements are correct EXCEPT ．
A．After getting the keys，the owners sometimes have a party
B．People can borrow the whole money for a new house from a bank
C．The sellers are more interested in the first-time buyem
D．People care for mortgages，interest rates and the prices＆houses
74．Which of the following is NOT mentioned in the passage?
A．Lawyers． B．Owners． C Collectors D．Surveyors．
75．The passage is maybe one that ．
A．gives some advice on the house B．introduces a guide to visitors
