常見化學藥品的貯存
硝酸固碘硝酸銀，低溫避光棕色瓶。液溴氨水易揮發(fā)，陰涼保存要密封。
白磷存放需冷水，鉀鈉鈣鋇煤油中，堿瓶需用橡皮塞，塑鉛存放氟化氫。
易變質藥放時短，易燃易爆避火源。實驗室中干燥劑，蠟封保存心坦然。
解釋：
1、硝酸固碘硝酸銀，低溫避光棕色瓶：意思是說硝酸、固體碘和硝酸銀都屬于受熱見光易分解的物質，所以必須存放在棕色瓶里，并放在陰涼處。
2、堿瓶需用橡皮塞：意思是說盛放堿液的試劑瓶要用橡皮塞。
3、塑鉛存放氟化氫：意思是說氟化氫（氫氟酸）易腐蝕玻璃，因而必須存放在塑料或鉛制器皿中。
4、易變質藥放時短：意思是說易變質的藥品存放時間較短，即不能長久貯存，最好現用現配制[聯想：常見易變質的藥品有：①氫硫酸放久了，則大部分將揮發(fā)，部分被空氣氧化；②氯水長期存放將因慢慢分解而失效；③亞鐵鹽長期存放，則易被氧化為鐵鹽；④酸化的高錳酸鉀溶液長期存放則慢慢退色]。
5、易燃易爆避火源：意思是說易燃物質（如：二硫化碳、酒精、丙酮、苯、硫、磷、鎂粉等）和易爆炸的物質（如：氯酸鉀、硝酸銨等）存放時要遠離火源。
6、實驗室中干燥劑，蠟封保存心坦然：意思是說實驗室中用的干燥劑極易吸水，因而要用蠟封保存。

Dogs that can take out cash from ATMs and empty washing machines help disabled people lead more independent lives, but can they also help change disruptive (愛搗亂的) teenagers’ behaviour?
A unique TV experiment, “Dog House”, follows five unruly youngsters as they are taught to become dog trainers. The idea is simple. Kids really like dogs. But can the skills involved in training them―patience, consistency, rewarding good behaviour―give these teenagers the discipline they need in their own lives?
The teens involved were put forward by local schools in West Sussex, who had run out of ideas of how to deal with them.
Liam was typical―14 years old, bad-tempered, aggressive, foul mouthed and about to be permanently excluded from school. Allie, Rob and Ellie had similar problems―they couldn’t concentrate, they didn’t like being told what to do and they had serious anger problems. Katrina was different. She was so shy that she had developed fear of the outside world, she suffered from depression and had taken herself out of main-stream education.
Gradually, working with the dogs began to have an effect on the kids. But, in order to fully appreciate the significance of what they were doing, they needed to meet the disabled people who benefited from having these dogs. The meetings had a profound influence on the teenagers. After meeting Eileen Hobson and her dog Sailor, Liam changed his ways and his unlikely friendship with severely disabled wheelchair user Eileen blossomed.
Two months into the course Liam began to connect with the dogs too―particularly a young yellow Labrador called Aero. The relationship flourished so much that the dog often knew instinctively what the teenager wanted him to do before he’d even asked. “He just knows,” says Liam.
Liam’s school noticed a huge change in his whole outlook. His teacher Nick Brown said, “More than anything I see a confident and happy young man. It’s been excellent.”
56．The teens were selected to be dog trainers just because ________
A．they liked dogs very much
B．they came from the same local school
C．they ran out of ideas of how to behave in school
D．their teachers had some difficulty in dealing with them
57．What was Katrina’s problem?
A．She didn’t like being told what to do.
B．She had serious anger problems.
C．She was bad tempered and aggressive.
D．She had trouble in getting along with others because of her shyness.
58．The underlined word “ blossomed” in the fifth paragraph probably has the same meaning as ________
A．developed B．decorated C．expanded D．declined
59．From the passage we know that ________
A．all dogs can retrieve cash from ATMs
B．unruly youngsters can become good dog trainers
C．the skills in training dogs can really affect children’s behavior in school
D．the five teenagers were sullen and aggressive

Authorities did not release the gunman’s name, but Peter said he had no record of police contact or an arrest record while attending Northern Illinois.
DeKalb county coroner(驗尸官)Dennis J. Miller on Friday released the identities of the four victims who died in the county: Daniel Parmenter, 20, of Westchester; Catalina Garcia, 20, of Cicero; RyanneMace, 19, of Carpenters-ville; and Julianna Gehant, 32, of Meridan.
“Two other victims died after being transferred to hospitals in other counties”, Miller said. Witnesses said the gunman, dressed in black and wearing a stocking cap, emerged (浮現)from behind a screen on the stage of 200-seat Cole Hall and opened fire just as the class was about to end around 3 p.m.
Officials said 162 students were registered for the class but it was unknown how many were there on Thursday.
Allyse Jerome, 19, a sophomore (大二學生)from Shaumburg, said the gunman burst through a stage door and pulled out a gun.
“Honestly, at first everyone thought it was a joke,” Jerome said. Everyone hit the floor, she said. Then she got up and ran, but tripped. She said she felt like “an open target”.
“He could have decided to get me, ” Jerome said on Friday. “I thought for sure he was going to get me.”
Lauren Carr said she was sitting in the third row when she saw the shooter walk through a door on the right-hand side of the stage, pointing a gun straight ahead.
“I personally army-crawled halfway up the passage,” said Carr, a 20-year-old sophomore. “I said I could get up and run or I could die here.”
She said a student in front of her was bleeding, “but he just kept running”.
More than a hundred students cried and hugged as they gathered outside the Phi Kappa Alpha house early Friday morning to remember Dan Parmenter, who was one of those killed.

You Can’t Do It Even If It Hurts Nobody
Who do you think breaks the law in our society？If you believe that only tough guys commit crimes，you may have to think again．Unlike in the movies，we can’t divide the world into bad guys and model citizens．Real life is much more complex．In the same way that diseases range from the common cold to fatal forms of cancer，crimes vary in degree．For example，smoking in an elevator will inconvenience people．but much less than threatening them with a gun．
In addition to breaking the law themselves，people tolerate various levels of crime．Why are we tolerant of some crimes？It may be that，by seeing others do something，we accept it more easily．For instance，most people will find it easier to speed on a highway when everybody else is driving over the speed limit．So the people around us influence how much law－breaking we can tolerate．
We must also wonder whether seeing violence on television or reading about it in the newspapers every day makes us tolerate crime more than we should．We become used to seeing blood on the news on television，or in magazines．Because we see thousands of dead people on TV，maybe we just try to ignore the situation behind the violence．
If so many citizens tolerate violence and crime，or even commit crimes themselves，it may simply be because of the human mind. Our minds may not care about specific laws．Instead，our minds may have a system of values that usually prevents us from hurting other people to improve our own lives．Yet，when it comes to respecting the rights of a mass of unknown individuals，we might not be so responsible．While most people would not steal a wallet containing＄50，they may not mind cheating on taxes，because cheating on taxes does not hurt any one person．It hurts society，but “society” remains an abstract idea that is not as real as a neighbor or a friend’s friend．
When we realize that many people have misconceptions about law－breaking，we could think it isn’t surprising that so many people have criminal records．How could we improve the level of honesty in our society？Would severe laws help make our society better？Probably not．Honesty will have to come from social pressure: in the family，at school，on the job，each and every one of us can encourage honesty by showing which behaviors are unacceptable．And teaching respect should become everyone’ s responsibility．
64．According to the author，“Real life is much more complex” probably means
A．there is a wide range of people and crimes in the real life
B．smoking in an elevator goes against laws in the real life
C．there are more crimes than diseases in the real life
D．model citizens sometimes break laws in the real life
65．What does the author think of the people who cheat on taxes？
A．They take no notice of the human mind．
B．They break the laws unaccepted in their minds．
C．They hurt other people to improve their own lives．
D．They aren’t concerned with some particular laws．
66．People tolerate violence and crime because__________.
A．their behavior is the same as that of most other people
B．they pay no attention to the truth behind the crimes
C．most unlawful acts are not harmful to the individual
D．they hold mistaken beliefs about law－breaking
67．What is the author’s purpose in writing this passage？
A．To discuss whether laws are severe．
B．To remind people to behave with honesty．
C．To show people the importance of school education．
D．To explain why so many people have criminal records．

A popular saying goes，“Sticks and stones may break my bones，but words will never hurt me．”However，that’s not really true．Words have the power to build us up or tear us down．It doesn’t matter if the words come from someone else or ourselves---the positive and negative effects are just as lasting．
We all talk to ourselves sometimes．We’re usually too embarrassed to admit it，though．In fact，we really shouldn’t be because more and more experts believe talking to ourselves out loud is a healthy habit．
This “self―talk” helps us motivate ourselves，remember things，solve problems，and calm ourselves down．Be aware, though，that as much as 77％of self―talk tends to be negative．So in order to stay positive，we should only speak words of encouragement to ourselves．We should also be quick to give ourselves a pat on the back ,The next time you finish a project，do well in a test，or finally clean your mom，join me in saying “Good job!”
Often，words come out of our mouths without us thinking about the effect they will have．But we should be aware that our words can call certain responses in others．For example，when returning an item to a store，we might use words，friendly language during the exchange．And the clerk will
probably respond in a similar manner．Or harsh and critical language will most likely cause the clerk to be defensive．
Words possess power because of their lasting effect．Many of us regret something we once said．And we remember unkind words said to us! Before speaking，we should always ask ourselves：Is it true? Is it loving? Is it needed? If what we want to say doesn’t pass this test，then it’s better left unsaid．
Words possess power：both positive and negative．Those around us receive encouragement when we speak positively．We can offer hope，build self―esteem and motivate others to do their best. Negative words destroy all those things．Will we use our words to hurt or to heal? The choice is ours．
68．The main idea of the first paragraph is that ．
A．not sticks and stones but words will hurt us B．inspiring words give us confidence
C．negative words may let us down D．words have a lasting effect on us
69．There is no sense for us to feel embarrassed when we talk to ourselves because――．
A．almost everybody has the habit of talking to themselves
B．we can benefit from talking to ourselves
C．talking to ourselves always gives us courage
D．it does no harm to have “self―talk” when we are alone
70．The underlined part in the third paragraph means that we should also timely ．
A．praise ourselves B．remind ourselves
C．make ourselves relaxed D．give ourselves amusement
71．The author would probably hold the view that ．
A．encouraging words are sure to lead to kind often
B．negative words may stimulate us to make more progress
C．people tend to remember friendly words
D．it is better to think twice before talking to others

Letter to the Editor
A heated debate is currently going on in our town．Should we allow the cinema to be constructed in the Havenswood Shopping Center? There is just one large lot left to build on，and the theater would use up all of that space．Some people are excited at the idea of finally having our own movie theater．Others would rather travel ten miles to the nearest theater to keep our quiet town the way it is．They say it is enough to have Marvin’s Movie Video Rentals．After all，Marvin’s store keeps thousands of the latest videos．
There are certainly benefits to renting videos．For one thing, you can plan your own schedule when it is convenient for you．You can relax on your sofa，and take a break whenever you need one．You can also talk to others without bothering any strangers seated nearby．In addition，it is a less expensive way to view a movie，especially if more than one person is watching the video．
On the other hand．seeing a movie in a theater is an experience all its own．First，you can see the movie on a wide screen as the filmmaker intended．To be viewed on a television screen, a film must be changed in some way to make it smaller．One is the “pan―and―scan” method，which involves removing some of the details in the picture．The other way，called “l(fā)etterboxing”，keeps the image the way it is on the big screen，with one annoying exception; because the big―screen style is wide，the same picture on a television screen must be long and narrow．
Another problem is sound．The sound from a television cannot compare to the sound system in a theater．Your experience of a movie improves when you can clearly hear all of the sounds．
Furthermore，at home，viewing companions often talk during a movie，which makes you miss out on what’s happening in the film．
Besides．having a movie theater will not mean that you can’t still go to Marvin’s! You will just have a choice that you didn’t have before．Isn’t it time for Havenswood residents to enjoy a little progress?
72．Who is the author probably?
A．An editor of a newspaper．
B．The manager of the nearest theatre．
C．A concerned citizen in Havenswoed．
D．The owner of Marvin’s Movie Video Rentals．
73．What is the advantage of renting videos?
A．It won’t take up the large lot in the town．
B．There’s no strict limit to the viewing time．
C．People can enjoy better sound system．
D．People can fully concentrate on their movies．
74．In the author’s opinion．the construction of a theatre will ．
A．reduce the profit of the Movie Video Rentals B．save movie-goers money and time
C．offer people another experience D．disturb the peace in the town
