答案不唯一

1.Nowadays,to keep up with the quickening pace of our society,many people turn to fast food to cut down their time spent in eating.Actually,I am no exception.Well,what exact attitude should we take towards fast food?Firstly,we acknowledge that it really gratifies our strong desire to save time.Nevertheless,every coin has two sides.Relying on fast food on a long-term basis may cause a person to suffer from malnutrition.What is more serious is that some fast food contains many calories which can turn into fat.As we know,too much fat is harmful to our health.Therefore,manufacturers should try new ways to Therefore,manufacturers should try new ways to cook fast food,such as adding in more nutritional ingredients,and manage to create more kinds of fast food to meet people's needs.Nonetheless,we should remember that we should not depend too much on fast food.
2.Fast food is becoming more and more popular in China ,especially among children and teenagers .There are several reasons for its popular .First ,it is very convenient and saves a lot of time .You just go into a fast food restaurant ,order your food ,and your food is ready in time .Second ,you can either eat it there or take it away .Third ,the envronment of fast food restaurants is both clean and comfortable .Fourth ,it has excellent service ,and the quality of food is guaranteed .However ,it terns of nutrition ,IT is usually not a balanced diet and low in nutrittional value .Fast food is only a good choice when you are in a hurry and turn to it once in a while .But for people ,especially children ,eat fast food as little as possible .
3.水平高一点的：提纲：1．快餐正在流行.2．快餐的弊端.3．你对快餐的态度.Life pace moves very fast these days.People don’t like to waste time on their breakfast and lunch except their business luncheon and family occasions.They always have their meals out of or in their offices.With this kind of new custom,fast food is getting more and more popular.You may rind McDonald’s,Kentucky Fried Chicken,hainburger shops everywhere.In recent years,fast food rushes into China,and Chinese young people begin to be fond of it.But is anything popular a good one?The answer is No.It’s reported that fast food is unfit particularly for children who need more nutrition for their growth,for there is little nutrition in it.If you always have it,your health will be badly affected.Unfortunately,there are still many people spending much money on fast food,with anidea that they are enjoying themselves in a new life style.It is not easy dealing with popular things.Certainly we shouldn’t abandon something new rashly,and it’s not wise to give up eating forfear of being choked,but it’ s more important that we should accept it by carefully choice.Only in this way can we keep ourselves independent,and have the children grow healthily.And the same is true of the case of fast food.

There are all kinds of foods in the world. Which one is healthier, the Chinese food or the western food? Different people have different choices.
Some people like the Chinese food. Firstly, the Chinese food contains a lot of fruit and green vegetables. It is rich in fibre and low in sugar and fat. Secondly, the Chinese food is very delicious and has many dishes. It is nice to taste healthiest in the world. So Chinese people can keep fit and have white teeth.
We need healthy food
I need a balance of yin and yang to be healthy. So when I’m tried I eat hot yang foods.I eat yin foods like tofu when I’m too stressed out.I exercise every day. Usually when I come from school.I try to eat a lot of vegetables about ten or eleven times a week.I don’t like milk but I drink milk every day. Because my morther wants me to drink it,she says it’s good for my health.Of course,I like junk food but I eat it twice a morth.I often sleep nine hours every night.But sometimes I sleep six hours.At those day,I fell tired.I think it’s important to stay heaalthy, because healthy lifestyle help me get good grades.

The Advantages and Disadvantages of Eating Fast Food
Fast
foods,such as hamburger and pizza only need a short time to
order.Moreover,nowadays,the restaurants which sell them can be found
easily.Therefore,no matter when you are hungry,or wherever you are,there
is probably at least one fast food restaurant just a short drive away.
Another
advantage of eating fast foods is that they have a good taste.For
instance,french fries,spaghetti and fried chicken have special flavor
which make the consumers be addicted.Because in fact,such fast foods are
added with additives,such as Monosodium glutamate (MSG) and sodium
which can improve the taste of food.However,eating fast foods also has
disadvantage is that it is one of factors causing obesity.Generally,fast
foods have many of calories and these accumulate in the body as fat
deposits that can cause obesity.In addition,with obesity come other
problems like high blood pressure and diseases of the joints.Some
researchers have shown that there is a direct link between fast food and
obesity on children.
All in all,human being should think twice if they want to eat fast foods in order to keep away from the negative impacts.

The Advantages and Disadvantages of Eating Fast Food
There
are many reasons that many people love to eat fast food.It is fast and
easy to eat food which makes us satisfy.There are too many researches
about disadvantage of fast food.I think that fast food has more hamful
properties than benefit ones
The Advantages are only two:
1.It saves your time.
2.It catches with your taste buds.
The disadvantage lists is quite longer than the advantage lists and are as follows:
1.Heart
disease – High saturated and trans fat along with high sodium content
damages the arteries and high cholesterol clogs the arteries.
2.Obesity – High calories slowly settle down in your body and make you fat.
3.Peptic Ulcer – Excessive spicy foods induces peptic ulcer.
4.Lack
of essential nutrients –Being low on nutrients,these junk foods are
causing severe lack of essential vitamins,minerals,and other essential
components in our body.
5.Irregular food habits – These instant and
readily available foods have given us a very negative attitude and bad
food habits of eating while working or eating while driving or delaying
eating time.
6.Addiction – These are highly addictive.Once your child
get addictive,it will become very difficult for you to make them
understand all the pros and con.

小学英语书上讲的是fast food,我比较认同snack,fast food是个合成词,个人认为snack比较科学.

Fast food is the food that can help people save time and energy.Especially for the those who keep busy all the time.
Why is it called fast food?Because it can be prepared fast and you can buy it fast and you can eat it fast.But because it is too fast,it is not so healthy as those foods we have in normal way.
So,I think we can have the fast food when we are in a hurry or just when we want something else for change.
So,i think fast food should never be the main food for us.
And as a matter of fact,I love chinese food best.As it is both delicious and healthy.

书面阅读仍应该是我们读书的主要方式,并且要仔细品味；电脑阅读是娱乐性质的.

解题思路：（1）用人数×3得出总钱数，然后跟100作对比，即可进行判断；
（2）设3元一份的能买x份，则2.5元一份的能买35-x份，根据总钱数不超过100元列出不等式求出x的最大整数解即可．

（1）不够．
∵35×3=105，105＞100，
∴全买3元一份的，100元钱不够；

（2）设3元一份的能买x份，则2.5元一份的能买35-x份，
由题意得，3x+2.5（35-x）≤100，
解得：x≤25，
故3元一份的最多能买25份．

本题考点： 一元一次不等式的应用．

考点点评： 本题考查了一元一次不等式的应用，解决问题的关键是读懂题意，依题意列出不等式进行求解．

答案是B.
首先题目的要求是能“加热”,所以所求的两种反应物必须是能够在发生混合时候能够放热,由此可以排除选项C和D,注意熟石灰是生石灰与水反应放热后的产物,并不说明熟石灰与水混合可以放热.
这样就在A和B中选择正确的答案,很明显,浓硫酸是具有强烈腐蚀性的高危化学物质,要注意任何用于实际生产的化学物质都必须“安全”,所以最后答案是B.尽管生石灰CaO与水反应生成的熟石灰Ca（OH）2属于碱,但即使泄露对人体也不会造成太大伤害,日常生活中人们经常用熟石灰抹墙.
早说从经济效益看也是选便宜的生石灰比较合算,浓度达到98%的浓硫酸的价格可是不低的~

Today,most people do not have time to prepare their meals so fast food is the first choice that people can choose for their rush hour.There are two negative effects consumption on fast food.First effect is obesity risk.It is true that fast food is usually high in fat,calories,cholesterol,and sodium.All these cause of obesity if you eat too much fast food in the long term.In America,there are many overweight American children because of their parents.They are always busy thus their children are allowed to eat outside home and fast food is an easy way to choose.The children can buy a fast food everywhere for their meals because it is inexpensive and it is also quickly to get,for example.The second effect is fast food can lead to health problems not only obesity but also high blood pressure and heart disease.This problem is usually happened when you are old because your digest and your organ are not as well as when you were a child,as a result it can cause of disease easier.All in all,fast food is not totally bad food if you do not always consume it.You can eat but you also have to think about the effect that will come after too.

Fast food is becoming more and more popular in China, especially among children and teenagers. There are several reasons for its popularity. First, it is very convenient and saves a lot of time. Second, you can either eat it there or take it away. Third, the environment of fast food restaurants is both clean and comfortable. However, in terms of nutrition, fast food is far from satisfactory. It is usually not a balanced diet and low in nutritional value. Fast food is only a good choice when you are in a hurry and turn to it once in a while. It's good for people, especially children, to eat fast food as little as possible.

快餐的好处就是便宜，方便，省时，外加美味。适宜那些上班族和爱赖床的人。
