3.Some animals can be trained to help humans.For example,specially trained dogs help blind people walk around the town safely.Some kinds of monkeys can be taught things too.(36)C The monkeys pick up the phone when it rings,carry shopping bags and do housework.
In the wild,animals and humans are not usually friends.(37)F In Africa,the honey-guide bird works with humans to find food.The bird likes to eat the grubs (幼蟲)-a type of insect that lives inside a beehive (蜂巢,蜂窩).It knows how to find beehives but it can't open them and get the grubs.People like to eat honey,but they aren't very good at finding beehives.(38)B The bird flies to a beehive and people follow it.When the people open the beehive and take the honey,they give the grubs to the bird.
In Laguna in the south of Brazil,fishermen and dolphins work as a team.The ocean isn't very clean,so the fishermen can't see the fish.(39)G When the dolphins find a large group of fish,they make a noise to tell the fishermen.Then the dolphins push the fish to the beach.The fishermen wait in the water near the beach and catch a lot of fish in their nets.The fishermen's nets make it easier for the dolphins to catch fish too.In Laguna,fishermen and dolphins have been working together for many years.(40)E Meanwhile,the dolphins must be happy to help because they teach their babies how to work with the humans!
A.They attack each other for food or something else.
B.So the bird and the people help each other.
C.They can learn how to help people who can't use their arms or legs.
D.In fact,they usually help to get enough food for their babies.
E.The fishermen teach their children how to work with the dolphins.
F.However,there are a few interesting examples where they can work together.
G.However,dolphins can find them easily by using sounds.

分析 本文主要介紹人類和動物如何相互幫助的事情.例如:導(dǎo)蜜鳥知道如何找到蜂窩但打不開,而人喜歡吃蜂蜜但找不到蜂窩,這樣,人跟著導(dǎo)蜜鳥找到蜂窩打開它得到蜂蜜,導(dǎo)蜜鳥吃到幼蟲.這樣,相互幫助,各取所需.

14.A61.Susan is a big eater.She usually has a lot at every meal.So she wonders whether she could only eat less for the first meal of a day to lose weight.
C62.Tina is a fat girl who doesn't like exercise much.She just wants to lose weight by eating less but not doing exercise.
E63.Maggie is a busy office lady.She usually has to work overtime every day.So she could only have her dinner late at night.She wants to be slimmer so that she could be much more attractive.
D64.Judy is a fashionable designer.She hopes to have a slim shape as models.She usually doesn't have any regular meal,but has some snacks when she is hungry.

A.If you eat less for breakfast,you have a lower chance of losing weight.Breakfast is important.It gives the body sufficient energy to sustain itself through the morning,and it also stimulates metabolic (新陳代謝) activity in the body.Metabolism is what consumes fat and what makes us slimmer.So,don't forget to eat something for the breakfast.
B.What makes people fat is not the number of calories for one meal,but the total accumulated over time.So don't expect your weight to drop when you eat less for just one meal.This needs to be sustained over a period of time.After some time,you will notice a change.
C.Many people stop doing exercise when they eat less.When you do this,your body will burn less fat.So even if people take in less calories,they get rid of less too.The balance is then unchanged.
D.People gain fat not from the food they eat,but from the number of calories in the food.For example,a bunch of vegetables has just one tenth the calories contained in a small bit of chocolate cake.So make sure you have adequate regular meals,but firmly say no to various snacks,milk tea or even instant noodles.
E.If you ate your last meal right before going to bed,the calories accumulated from this meal could be twice the amount accumulated from a same meal if you ate it another time during the day.

 For some students,there are too few rules.These students will do little in school.They will not make good use of open education,which is very different from traditional education.These students may have a problem of getting used to making so many choices.(73)GThey worry about the rules even when there are no rules.Even a few rules will help this kind of students.The last point about open education is that some traditional teachers do not like it.(74)ATeachers who want to have an open classroom may have many problems at their school.
You now know what open education is,whose good points and bad points have been explained.You may have your own opinion about open education.I think that open education is a good idea,but only in theory.(75)FI believe that most students,but of course not all students,want some structure in their classes.They want and need to have rules.In some cases,they must be made to study some subjects.Many students are pleased to find subjects they have to study interesting.They would not study those subjects if they did not have to.

8.Facts About Goal Setting
These practical tips on goal setting can help make it easier to set and reach goals:
Specific,realistic goals work best.(21)G"I'm going to recycle all my plastic bottles,soda cans,and magazines"is a much more doable goal than"I'm going to do more for the environment."And that makes it easier to stick with.
(22)F It will probably take a couple of months before any changes-like getting up half an hour early to exercise-become a routine part of your life.That's because your brain needs time to get used to the idea that this new thing you're doing is part of your regular routine.
(23)A Say your goal out loud each morning to remind yourself of what you want and what you're working for.Writing it down works too.Every time you remind yourself of your goal,you're training your brain to make it happen.
(24)B The key to making any change is to find the desire within yourself-you have to do it because you want it,not because a girlfriend,boyfriend,coach,parent,or someone else wants you to.It will be harder to stay on track and motivated if you're doing something out of obligation to another person.
Roadblocks don't mean failure.Slip-ups are actually part of the learning process as you retrain your brain into a new way of thinking.It may take a few tries to reach a goal.But that's OK-it's normal to mess up or give up a few times when trying to make a change.So remember that everyone slips up and don't beat yourself up about it.(25)D

A.Repeating a goal makes it stick.
B.Pleasing other people doesn't work.
C.You should make a change in your life.
D.Just remind yourself to get back on track.
E.Set a goal and come up with steps to reach it.
F.t takes time for a change to become an establishedhabit.
G.When it comes to making a change,the people who succeed are those who set proper goals.

15.Building Trust in a Relationship Again
Trust is a learned behavior that we gain from past experiences,(36)B.That is a risk.But you can't be successful when there's a lack of trust in a relationship that results from an action where the wrongdoer takes no responsibility to fix the mistake.
Unfortunately,we've all been victims of betrayal.Whether we've been suffer from,lied to,misled,or cheated on,there are different levels of losing trust.Sometimes people simply can't trust anymore,(37)E.It's understandable,but if you're willing to build trust in a relationship again,we have some steps you can take to get you there.
l(38)Ahaving confidence in yourself will help you make better choices because you can see what the best outcome would be for your well-being.
l(39)CIf you've been betrayed,you are the victim of your circumstance.But there's a difference between being a victim and living with a"victim mentality".At some point in all of our lives,we'll have our trust tested or violated.
l  You didn't lose"everything".Once trust is lost,what is left?Instead of looking at the situation from this hopeless angle,look at everything you still have and be thankful for all of the good in your life.(40)Ginstead,it's a healthy way to work through the experience to allow room for positive growth and forgiveness.

12.Improve your memory
Do you find yourself forgetting where you left your keys or blanking out information on important tests?(36)B Before your next big exam,be sure to check out some of these tried and tested ways of improving memory.
Focus your attention on the materials you are studying.Attention is one of the major components(組成部分) of memory.In order for information to move from short-term memory into long-term memory,you need to actively attend to this information.(37)A
Structure and organize the information you are studying.Researchers have found that information is best organized in related groups.(38)E Or you can make an outline of your notes and textbook readings to help group related concepts (概念).
(39)F When you are studying unfamiliar material,take the time to think about how this information relates to things that you already know.By establishing relationships between new ideas and previously existing memories,you can greatly increase the likelihood of recalling(回想起) the recently learned information.
Pay extra attention to difficult information.Remembering information at the beginning or end of an article is easy.However,recalling information from its middle can be difficult.(40)C Another way is to try restructuring what you have learned so it will be easier to remember.When you come across an especially difficult concept,devote some extra time to memorizing the information.

A.Try to study in a quiet place and concentrate on your learning.
B.Fortunately,there are things that you can do to help improve your memory.
C.You can overcome this problem by spending extra time memorizing this information.
D.Use this approach in your own studies.
E.Try grouping similar concepts and terms together.
F.Relate new information to things you already know.
G.Repeat the information you are studying to improve memory.

13.Most people feel lonely sometimes,but it usually only lasts between a few minutes and a few hours.This kind of loneliness is not serious.In fact,it is quite normal.For some people,though,loneliness can last for years.(16)D
The first kind of loneliness doesn't last long.This is the most common type.(17)C The second kind is situational,it is a natural result of a particular situation.For example,family problem,the death of loved one,or moving to a new place.Although this kind of loneliness can cause physical problems,such as headaches and sleeplessness,it usually does not last for more than a year.
The third kind of loneliness is the most serious.(18)F People who experience habitual loneliness have problems socializing and becoming close to others.Unfortunately,many of them think there is little or nothing they can do to improve their condition.
Psychologists agree that one important factor in loneliness is a
person's social contacts.(19)E For instance,our families give us emotional support,our parents and teachers give us guidance,and our friends share similar interests and activities.However,psychologists have found that,though lonely people may have many social contacts,they sometimes feel they should have more.They question their popularity.
Psychologists are trying to find ways to help habitually lonely people for two reasons:they are unhappy and unable to socialize and there is a connection between habitual loneliness and seriousillness such as heart disease,(20)B

A.we live in a big family and we love our family members.
B.while temporary and situational loneliness can be a sad,and sometimes dangerous condition.
C.It usually disappears quickly and does not require any special attention.
D.Psychologits are studying this complex phenomenon,and have identified three different types of loneliness.
E.We depend on various people for different reasons.
F.Unlike the first two types,it usually lasts more than two years and has no specific cause.
G.a(chǎn)nd temporary and situational loneliness also need to pay attention to.
