1．How to Become Best Friends with Your Dormmates
Do you feel nervous and stressful about living in the dormitory？Sharing a room with strangers may be challenging at the beginning，but it will turn out to be a precious experience in your life．Here are some tips on how to become best friends with your dormmates．
Agree on Some Basic Rules
（36）D．Make a list of the things that are/aren't allowed to both of you and stick to it．Decide on the studying time，cleaning and visiting hours．Not only will it make your routine easier，but can also help to avoid misunderstanding and quarrels．
Discuss the issues at once
You will escape many fights if you start talking about the problem once you feel it's necessary．When you accumulate the little things，they grow bigger and you may say some unpleasant things you don't really mean．Your dormmates simply cannot know or notice some things．（37）G．
Respect Your Dormmates and Their Stuff
Using without asking is the cause of most conflicts and misunderstandings between dormmates．（38）C．If you think that wearing their cosmetics is okay，they may think in an absolutely different way．Always ask for permission when you want to borrow，use or take any item．
Get to Know Each Other Better
You won't become best friends at once，but you can do a lot in order to establish a good relationship from the very start．（39）F．Everybody loves to be asked questions about their personality．Getting to know each other will make your living together less stressful and you may have pretty much in common!（40）A
Your dormmates may be from other countries with different traditions，religion and views．Be careful with the stereotypes and prejudgment，your ideas about the subject may be superficial and incorrect．Most probably your overseas dormmates will need some help during the period of adaptation to the new surrounding and lifestyle．Sharing a room with an international student is a unique chance to learn another culture and language．Don't miss it!
A．Tolerance Makes a Difference
B．Learning from each other
C．Being dormmates doesn't mean sharing everything with each other
D．This is the essential rule of any good relationship
E．Tell them your own interests and preferences
F．Take an interest in their hobbies，family or academic preferences
G．That's why negotiations are always the right thing to consider．

18．Two weeks before my 12th birthday，my teacher asked me to conduct an experiment．When I mixed some powder together，they exploded．Molten lava hit me in the face，but I felt no pain．
I vividly remember standing there in a state of calmness．I thought I was in a dream，but however hard I struggled to swim to the surface of consciousness，I couldn't wake up．I didn't understand how terrifying it was until I heard people saying，"Who's that？"That's when I knew I was unrecognisable．
I was taken to hospital，but the doctors didn't know what to do with me．Later I was flown to Houston for surgery．Between the ages of 13and 16，I had 40operations．As each operation came and went，my vision would come back and then fade again．Eventually，it faded completely and I had what was left of my eyes removed for cosmetic（整形）reasons．
Since then，I have lived in total darkness．Most blind people，even if they don't have any sight they're aware of，are still able to perceive light．That gives them a sense of day and night．But not me．I absolutely lost that sense of time passing．
For many years，I felt my sight loss darkening my life like the loss of my parents from which I would never recover．But when I was in my 40s，I realised I had to find a way to live．I trained to become a counsellor，and that has helped me see my experiences in a different way．I can't fix people's broken lives-just like I can't fix my sight-but I can help them find a way to manage．
Sometimes it feels as if all the struggles and negative experiences I've lived through were in fact a kind of preparation for helping others to make their own way towards the light．
24．When the explosion happened，the author feltA．
A．cool          
B．terrified          
C．upset             
D．a(chǎn)nxious
25．What can we know from the passage？C
A．The author lost her sight but her eyes remained．
B．The author recovered from her sight loss soon afterwards．
C．The author suffered a lot in her teens．
D．The author still has difficulty waking up from her dream．
26．What does the underlined word"perceive"in Paragraph 4mean？B
A．Predict．
B．Sense．
C．Watch．
D．Distinguish．
27．What is the author's purpose of writing this passage？B
A．To describe how hard a life the blind are living．
B．To suggest an attitude towards life through her story．
C．To encourage the disabled to be brave．
D．To blame the teacher for his irresponsibility．

2．Quickly ask yourself：What did you eat today？Now tell me how you actually feel．If you're complaining of stress，anxiety，depression，aches and pains，foggy thinking，or just a general lack of energy，a new medical theory will blow your mind．The chances are that those disease-like symptoms are all the result of what's called hidden food allergies（過敏反應(yīng)）．
This is what Ken Drew found out when he was lucky enough to be recommended to medical practitioner Dr．Patel．Patel is considered something of a genius，and has been called a modern day Louis Pasteur．You've heard of him，of course-Pasteur figured out how to keep milk from getting spoiled．Dr．Patel is like a Louis Pasteur for keeping your body from getting spoiled from chronic（慢性的） diseases．
"Foggy thinking，slightly constipated（便秘的），heart pain，…you name it．It's part of getting old，"you say．"It's just stress．"Most of the body's immune defenses are all located in your stomach，so when you have a hidden food allergy and you expose yourself to harmful foods，your defenses malfunction（故障） and disease-carrying bacteria take over．Had you not eaten that one food you were allergic to for breakfast，you would never have got sick．
Together，Dr Patel and Ken Drew have developed the Reverse My Disease program，which claims it can bulletproof your body against diseases like arthritis（關(guān)節(jié)炎），Alzheimer's，diabetes，heart disease and cancers．You won't need a prescription and there isn't any kind of medical procedure involved．There's no medical jargon，no complicated diet to do．What it does do is claim to tell you how to hack your body's natural defense system．
Dr．Patel has remained under the radar of the entire medical establishment because his ideas are so threatening to doctors who don't want you to stop being sick enough for them to write you prescriptions．Those doctor visits cost you，so check out Reverse My Disease  if you want to prevent disease by learning how to eat food that won't harm your body．
66．We can learn from the passage that Louis PasteurD．

B．has developed the Reverse My Disease program with Dr．Patel．

D．might be a great scientist who did research on bacteria．

B．their immune defenses are all located in your stomach．
C．they don't eat the right food．

19．You often find somebody who works around you complaining all the time，don't you？
（36）CAbout 70% of Americans say being around nonstop complainers sometimes has a bad influence on them．Luckily，here are 4tips to help form positive patterns．
1．Self-awareness
When a negative thought pops into your mind，immediately correct it．Instead of telling yourself"That's a nice shirt，but I can't afford it，"change the message to"That will look great with my black pants when I can afford it．"（37）DOf course，everyone complains sometimes．But the less frequently you complain，the better you will feel．
2．Distance yourself（38）FExcuse yourself and go somewhere quiet，somewhere outdoors in the fresh air．Think of something pleasant before returning．You have to take this seriously because negative people can and will pull you into the quicksand（困境）．
3．Don't try to change complainers
If you find yourself trapped in a group of complainers in a meeting or at a social event，simply choose silence．Let their words bounce off you while you think of something else．Attempting to stop the complaining can make you a target．（39）EIf someone says，"I hate Mondays，weekends are too short，"try to think，"I'm glad I rested up over the weekend，so I'm ready to make some improvement on that big project．"
4．（40）BWhen someone is shouting at you angrily，throw the responsibility back at them by asking，"So what do you intend to do about it？"In most cases，complainers don't really want a solution．They just want to speak them out．If you make them aware that they themselves have to find the solutions，they will leave you alone and find someone else to complain to．If so，you will be happy．

A．Find solutions
B．Change responsibility
C．You have got a lot of company．
D．By doing this，it will lead to positive behaviors．
E．But you can redirect the discussion in your own mind．
F．Whenever possible，escape from negative conversations．
G．You will never know what they are going to talk about．
