17 Some people think that they can learn better by themselves than with a teacher. Others think that it is always better to have a teacher. Which do you prefer? Use specific reasons to develop your essay.
Most of us can learn how to do something simple on our own with just a set of instructions. However, to learn about something more complex, it's always best to have a teacher.
Teachers bring with them varied and useful backgrounds. They've been trained to teach individuals in different ways depending on their style. For instance, omen students learn better by discussing a topic. Others learn more by writing about it. Teachers can help students learn in the way that's best of each student. A textbook or a manual can only give you one way of learning something. Plus they're only as helpful as your ability to understand them. A good teacher can adapt her teaching to your needs.
Teachers help you focus on what you're learning. If you're learning something by yourself, it's easy to become distracted, and go on to other activities. Teachers keep your attention on the subject. They also approach a subject logically, taking it one step at a time. On your own, it's tempting to skip parts of the learning process you think you don't need. That can binder your ability to really understand the subject.
Learning a subject on your own is a very narrow way of learning. You can only use the information you get from the textbook. With a teacher, you get the information in the written materials as well as the teacher's own knowledge of the topic. Teachers can also provide extra materials to broaden the scope of what you're learning.
There's nothing wrong with studying on your own, and a learner can always benefit from some quiet study. For the best possible learning, though, a good teacher is the biggest help you can have.

She doesn't single out one employee for better（or worse）treatment than the others. A poor supervisor has favorites. Sometimes she'll even use her favorites to spy on other employees. She expects them to tell her what the others are saying about her. This can cause a lot of bad feeling among employees.
A good supervisor gives clear and understandable directions. She doesn't constantly change her mind about what she wants employees to do. She also doesn't get angry with an employee who is confused and needs her to explain the directions again or more fully. Delegating authority well is another quality of a good supervisor. She knows how to use the skills of her employees to best advantage. A poor supervisor insists on doing everything herself. She is unwilling to give any authority to others.
A good boss evaluates her employees on a reasonable ser of criteria, not on how she feels about them personally. And she lets the employees know what those criteria are, so they have a fair chance of meeting them.

19 Should governments spend more money on improving roads and highways, or should governments spends more money on improving public transportation （ buses, trains, subways）? Why? Use specific reasons and details to develop your essay.
Governments should definitely spend more money on improving all forms of public transportation. These include buses, subways and trains. This is the best way to preserve natural resources and reduce pollution.
As a planet, we're dealing with a finite amount of natural resources. Once they're gone, they can't be replaced. They can't fill our need for oil and gasoline forever. But we seem to forget that and consume them at an incredible rate. In wealthier counties, some families have two or three cars. As soon as teenagers get their driver's licenses, they're given cars so their parents won't have to drive them places.
Public transportation hasn't been sufficiently developed. Because of this, suburban areas surrounding cities have been allowed to sprawl more and more widely. This means that people can't even go to the store without having to hop into the car. Everything is too far away from where they live. If there were better and more frequent public transportation, people would be able to give up their cars for local driving.
As a result of all the cars being driven, we're dealing with terrible pollution problems. In big cities, there are days during the summer when the elderly and people with respiratory problems are advised not to leave the house. Ten years ago this was unheard of! Now it's the norm. Public transportation would cut down considerably on air pollution.
Public transportation also encourages a sense of community. People who travel to work together all the time get to know each other. Car isolate us from neighbors. However, people feel they need to drive because they can't depend on public transportation to fit their schedules. If more money were available, buses, subways and trains could run 24 hours a day. Then they would be available all the time to the people who need them.
I always try to take public transportation whenever possible, and I encourage friends and neighbors to try it too. I think we must support public transportation in order to create a better world.
