The Importance of a Balanced Diet

A balanced diet is crucial for maintaining good health and overall well-being. It refers to consuming a variety of foods from different food groups in the right proportions. In this article, we will discuss the importance of a balanced diet and how it can benefit our bodies.

Firstly, a balanced diet provides all the essential nutrients that our bodies need to function properly. These nutrients include carbohydrates, proteins, fats, vitamins, minerals, and water. Each nutrient plays a specific role in our body, and a deficiency in any of them can lead to various health problems. For example, lack of vitamin C can cause scurvy, while not consuming enough calcium can result in weak bones and teeth.

Secondly, a balanced diet helps to maintain a healthy weight. Consuming excessive amounts of unhealthy foods, such as those high in saturated fats and sugars, can lead to weight gain and obesity. On the other hand, eating a balanced diet that includes a variety of fruits, vegetables, whole grains, and lean proteins can help us maintain a healthy weight and reduce the risk of chronic diseases, such as diabetes and heart disease.

Furthermore, a balanced diet boosts our immune system. The nutrients found in a balanced diet, especially vitamins A, C, and E, help to strengthen our immune system, making us less susceptible to illnesses and infections. A strong immune system is essential for fighting off harmful bacteria and viruses and keeping us healthy.

In addition, a balanced diet promotes good mental health. Studies have shown that certain nutrients, such as omega-3 fatty acids found in fish, can help improve brain function and reduce the risk of mental disorders, such as depression and anxiety. A diet rich in fruits, vegetables, and whole grains also provides antioxidants that can protect our brain cells from damage caused by free radicals.

Lastly, a balanced diet improves our digestion. Consuming a variety of fiber-rich foods, such as fruits, vegetables, and whole grains, helps to promote regular bowel movements and prevent constipation. It also provides the necessary fuel for the beneficial bacteria in our gut, which play a crucial role in our digestion and overall gut health.

In conclusion, a balanced diet is essential for maintaining good health and overall well-being. It provides our bodies with the necessary nutrients, helps maintain a healthy weight, boosts our immune system, promotes good mental health, and improves digestion. By making conscious choices about the foods we consume, we can ensure that we are giving our bodies the nutrition they need to thrive.

The Impact of Fast Food on Our Health

Fast food has become increasingly popular in our modern society due to its convenience and affordability. However, the consumption of fast food has been linked to various health problems. In this article, we will discuss the impact of fast food on our health and why it is important to limit our intake.

One of the main concerns with fast food is its high levels of unhealthy fats and sugars. Fast food is typically fried in unhealthy oils and contains excessive amounts of salt, sugar, and saturated fats. Consuming these unhealthy fats and sugars on a regular basis can lead to weight gain, obesity, and an increased risk of chronic diseases, such as diabetes and heart disease.

Furthermore, fast food is often low in essential nutrients. It lacks the vitamins, minerals, and fiber that our bodies need to function properly. Instead, it is packed with empty calories that offer little nutritional value. This can lead to malnutrition and deficiencies in essential nutrients, which can affect our overall health and well-being.

Another issue with fast food is its large portion sizes. Fast food restaurants often serve oversized meals that contain significantly more calories than our bodies need. This can lead to overeating and contribute to weight gain. Studies have shown that people who consume fast food regularly are more likely to consume more calories overall compared to those who opt for healthier food options.

Moreover, fast food is often highly processed and contains artificial additives and preservatives. These additives can have negative effects on our health, such as increasing the risk of allergies, disrupting our hormones, and contributing to the development of certain cancers. Consuming these artificial additives on a regular basis can have long-term detrimental effects on our health.

In addition, fast food is associated with poor dietary habits. People who frequently consume fast food are less likely to consume fruits, vegetables, and whole grains, which are essential for a balanced diet. This can lead to a lack of essential nutrients and an increased risk of various health problems, including digestive issues, weakened immune system, and poor mental health.

In conclusion, the consumption of fast food can have a significant impact on our health. It is high in unhealthy fats and sugars, low in essential nutrients, often served in large portion sizes, and contains artificial additives and preservatives. By limiting our intake of fast food and opting for healthier food options, we can improve our overall health and reduce the risk of chronic diseases.

【请你一试】

完成句子。

1．I can see________(5箱苹果)on the table．

2．There are_______(6片面包)in the bag．

3．She has_______(1杯牛奶)for breakfast.

4．He can drink______(12瓶水)a day.

【分析归纳】

英语中的名词可分为可数名词和不可数名词。凡是可以计数的名词叫可数名词，凡是不可以计数的名词叫不可数名词。可数名词通常有单数和复数两种形式。例如：car － cars，bus － buses， boy － boys， child － children， woman － women。可数名词前面可以用不定冠词a／an，数词或some， any， many等词语来修饰。例如：a girl， an orange， two students， four classes ， some cakes， many books。

不可数名词通常只有一种形式，没有复数形式。不定冠词a／an，数词或many不能和不可数名词连用，但是some， any， a little，much可以和不可数名词连用。例如：some rice， a little water，much meat 。不可数名词可以和一些量词短语搭配使用，这些量词短语中的名词是可数名词，有单复数形式。例如：a glass of water一杯水，three cups of tea三杯茶，four bag so frice四袋大米。

根据以上语法规则，

1．five bags of apples，

2．six pieces of bread，

3．a glass of milk，

4．twelve bottles of water。

选择填空。

1．－Would you like some______________？

A．cakes B．bananas C．tea D．apple

2． There are many____________in the school.

A．boy B．girl

C．water D．students

3．Tom is____________ American boy. He is in China now.

A．a B．an C．some D．much

4．I have_____________ here．

A．four bottle of water B．four water

C．four bottles of water D．four toy

5． There is___________ milk in the glass. Can you give me a full One？

A．little B．much C．many D．a

6． There____________much juice in the bottle． Would you like some？

A．are B．is C．has D．have

－I can see two.

A．How many B．What

C．How D．Where

8．Could you help me， please？ I want to carry___________to the room.

A．a box of apple B．two box of apples

C．a box of apples D．some apple

【答案详解】

1．C 从下句答语中的a little可知，问句中的名词应是不可数名词才符合上下文情景，C项的tea是不可数名词。而A，B，D三项均为可数名词不能和a little对应使用，因此正确答案为C。

2．D 句中的many只可以修饰可数名词的复数形式，A，B两项的'名词都是可数名词的单数形式，C项是不可数名词。D项的students是复数名词，应为正确答案。

3．B句中的boy是可数名词的单数形式，选项中的some和much修饰名词的复数形式或不可数名词，不能用来修饰单数名词boy。修饰以元音音素开头的单数名词时常用冠词an而不用a。

4．C 选项中的water是不可数名词，可以和一些量词短语搭配使用，而B项不符合要求。因量词bottle前面是数量词four，所以应用复数形式bottles，A项应排除掉，C项正好符合题意。D项的toy为可数名词，和数词four连用时应用复数才正确。

5．A milk为不可数名词，不能用many或a来修饰，故应排除掉C和D。第二句意思是请给我一瓶满的。由此可知，如果选much，符合语法要求，但语意上前后矛盾，因此选little既符合语法要求又符合题意。

6．B 句中的主语juice是不可数名词，谓语动词应用单数第三人称形式，所以B为正确答案。

7．A 从答句的意思我能看到两块(蛋糕)。可以看出，问句应该是询问数量的，而选项中只有How many可以表达此意。

8．C apple是可数名词，当和量词短语及some搭配使用时，必须用复数形式apples，而A和D两项中的apple均没加s，因此应排除掉。B项中的box和two连用时应用复数形式boxes才正确。

B

【请你一试】

用some或any填空。

1．There are_____________flowers on the table．

2．Is there_____________milk in the bottle？

3．I have______________money.

4．Do you have_______________bananas？

5．－Would you like _____________ coffee， please？

－ No， thanks.

【分析归纳】

some和any都是表示不定数量的词，后面可以接可数名词的复数，也可以接不可数名词。some常用在肯定句中，意为“一些”。any一般用于否定句或疑问句中，意思是“一些”，“任何的”，表示不肯定和疑问的语气。例如：

I have some friends in England．在英国我有一些朋友。

Do you have any friends in England？你在英国有朋友吗？

－Is there any rice in the bag？口袋里有大米吗？

－ Oh， let me see． Yes， there is some rice in it. 让我看一看。是的，有一些。

注意：在表示请求、建议、征求对方意见以及邀请，并想要得到肯定回答时，通常用some。例如：

－Would you like some tea？请喝茶好吗？

－ Yes， please． 好的。

答案：

1．some 2． any 3．some

4．any 5． Some

【知识迁移】

判断正误，并改正错误。

1．There is any juice in the bottle． Would you like some？

2．I don’ t have some oranges here．

3．－Would you like any coffee？

－ Yes， please．

4．I can see any kites on the table．

5．－Is there some milk in the glass？

－ No， there isn’ t some．

【答案详解】

1．此句是个肯定句，依据语法规则，肯定句中用some而不用any，所以应把any改为some。

2．some改为any。

3．在表示请求、建议、征求对方意见以及邀请，并想要得到肯定回答时，通常用some。因此，句中的any应改为some才正确。

4．肯定句中用some而不用any，将any改为some即可。

5．否定句或疑问句中，通常用any，意思是一些，任何的，表示不肯定和疑问的语气。因此，上下两句中的some都要改为any。

B．Here you are．

C．What would you like， Tom？

D．Anything to drink？

E．What about you？

【分析归纳】

要做好完成对话题，首先通读整段对话，对对话内容、上下文情景及参与对话的人物有所了解。补全对话时，要认真分析上句或下句，问句或答句，使你所填的句子符合上下文意思，整段对话通顺完整，意思连贯。通读整段对话可知，这是Ann和Tom在商店里的一段对话。他们在商量买什么吃的和喝的东西。从下句的回答可以看出，第一空填C．What would you like， Tom？第二空的下句是A glass of juice． 因此选择D．Anything to drink？表明Ann想知道Tom要喝点什么。从Ann的回答可以知道，Tom是在问她想要点什么，因此第三空填E． What about you？第四空填A．Some cakes？ Tom是在问她想要点蛋糕吗？ 第五空填B．Here you are．

Woman：Would you like 4 to 5 ？

Meimei：Certainly. I’ m 6 I’ d like a glass of apple juice． Do you have 7

ice cream？

Man：Sure， we 8 Here you are．

【答案详解】

1

．rice是不可数名词，故此空填some。2－3．询问别人需要什么时常说What would you like？所以第二空和第三空分别填would和like。

4－5．从下面答句的意思“我想要一瓶苹果汁”得知上句是问你想要点什么喝的？因此这两空填something和drink。

6．我想要一瓶苹果汁。意思是说她渴了，所以此空填thirsty。

7．ice cream是不可数名词，所以填any。

8．此空填do正好和上句Do you…？句型相对应。

D

【请你一试】

翻译下列句子。

1．早饭你想吃点什么？

2．你想要面包吗？

3．我想要点蛋糕、两个鸡蛋和一杯奶。

【分析归纳】

would like意为想要，用来委婉提出请求、建议或陈述个人的想法等。在意思上相当于want，但语气上要比want委婉，更客气、更礼貌。would like后接名词，表示想要什么。如果你自己想要什么就可以说I’ d like． . . ，如果你问别人想要什么可以说Would you like．？或What would you like？

对于Would you like．？提出的建议或请求，肯定回答可以说Yes， please． /Yes， thank you. /Yes， a little more． 如果不需要，你可以回答No， thank you. /No， thanks. 对于What would you like？的回答可以直接说出想要的东西，即I’ d like例如：

－Would you like a cup of tea？你想来杯茶吗？－Yes， please． /No， thanks. 好的，请吧。／不用了，谢谢。

－What would you like？你想要点什么？

－I’ d like some coffee． 我想要点咖啡。

1．What would you like for breakfast？

2．Would you like some bread？

3．I’d like some cakes， two eggs and a glass of milk.
