    【题目】阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

    Are energy drinks safe? In spite of 【1】 known dangers of energy drinks, the market for them is booming. The Global Energy Drink market is expected 【2】 (reach)$72 billion by 2024. This is great news for energy drink manufacturers, but what are 【3】(consumer)really getting when they buy these drinks?

    Energy drinks can cause dehydration( 脱水). The main source of energy in most energy products is caffeine. It can be 【4】(particular)harmful for people who drink these products 【5】 the first time and don’t compensate with extra water, says nutritionist Beth Warren.

    Energy drinks can increase heart rate. Caffeine also 【6】(contain)a heart rate risk, says nutritionist Lisa Cohn, 【7】 found that energy drink abuse among teens caused increased risk of heart attack, especially in those with potential heart conditions.

    Energy drinks can damage teeth. Energy drink products contain citric acid( 柠檬酸), which does harm to teeth. A study 【8】(compare)sports drinks and energy drinks found that energy products have significantly 【9】(high)acidity and greater capacity to dissolve enamel( 牙 釉 质 )compared to sports drinks. In fact, the 【10】(lose)of enamel after exposure to energy drinks was more than twice higher than after exposure to sports drinks.

    【答案】

    【1】the

    【2】to reach

    【3】consumers

    【4】particularly

    【5】for

    【6】contains

    【7】who

    【8】comparing

    【9】higher

    【10】loss

    【解析】

    这是一篇说明文，主要介绍了功能饮料的坏处。

    【1】考查冠词。句意：尽管功能饮料已知的那些危害，但它们的市场正在蓬勃发展。这里的危害指的是大家都已经知道的一些危害，是特指，故填the。

    【2】考查非谓语动词。句意：预计到2024年，全球功能饮料的市场会达到720亿美元。be expected to do sth“期望做某事”。故填to reach。

    【3】考查主谓一致。句意：这对于功能饮料厂商来说是大大的好消息，但是消费者当他们购买功能饮料的时候他们真正获得的是什么呢？这个疑问句中，因为用的是are getting…，所以主语要用复数，故填consumers。

    【4】考查副词。句意：营养学家Beth Warren说，这对于第一次喝这些饮料的而且不补水的人而言，尤其有害。这里是修饰形容词，需要用副词。故填particularly。

    【5】考查固定短语。句意：营养学家Beth Warren说，这对于第一次喝这些饮料的而且不补水的人而言，尤其有害。固定短语for the first time（第一次），故填for。

    【6】考查时态和主谓一致。句意：营养学家Lisa Cohn说，咖啡因也有心率加快的风险。她发现青少年间的功能饮料滥用提升了心脏病的风险，尤其是对那些有潜在心脏问题的人。整篇文章的主要时态是一般现在时，这里说咖啡因的影响也是一种客观事实，所以也用一般现在时。主语为caffeine 。故填contains。

    【7】考查定语从句。句意：营养学家Lisa Cohn说，咖啡因也有心率加快的风险。她发现青少年间的功能饮料滥用提升了心脏病的风险，尤其是对那些有潜在心脏问题的人。分析句子成分，这里是非限制型定语从句，先行词Lisa Cohn在定语从句中作主语，故填who。

    【8】考查非谓语动词。句意：一项将运动饮料和功能饮料进行比较的研究发现：与运动饮料相比较之下，功能饮料酸度更高，更容易溶解牙釉质。分析句子成分可知，这里是非谓语动词作定语，修饰study，研究跟比较之间是主动关系，故填comparing。

    【9】考查形容词比较级。句意：一项将运动饮料和功能饮料进行比较的研究发现：与运动饮料相比较之下，功能饮料酸度更高，更容易溶解牙釉质。这里是两者进行比较，所以要用比较级。故填higher。

    【10】考查名词。句意：事实上，喝了功能饮料后，牙釉质的失去量比喝了运动饮料后要高出两倍多。分析句子成分，这里是作主语，而且前面有冠词修饰，所以要用名词。故填loss。

    One day I saw a girl riding a bike along the street. All of sudden, she knocked down an old man whom was crossing the street. Instead of helping him up, the girl blames him angrily for the accident. Then he rode away even without looking back. A moment late, she found her shoes on the back of the bike missed. She raced back immediately to the spot where the accident was happened. Much to her surprised, she saw the old man waiting for her. The girl felt real ashamed when the old man handed the shoes to her. I think that we shouldn’t do as the girl did to the old man, but that everybody should be kind to each other.

    【题目】阅读下面短文，根据其内容写一篇60词左右的内容概要。

    CLEAN UP YOUR BUTTS AND BAGS

    All sorts of items become litter, but two of the most common and most dangerous are cigarette butts and plastic bags. Litter is a big problem for our environment, but it is a problem that individuals can easily do something about. Not littering at all or cleaning up litter, such as cigarette butts and plastic bags, greatly improves the quality of our environment.

    Although cigarette butts are small, they are bad for the environment. Over 1,600 billion cigarettes are smoked each year in China and large quantities of the butts are thrown away. Worldwide, about 4.5 trillion butts are littered every year. Apart from the fact that butts spoil the beauty of the environment, they contain some very toxic chemicals. These find their way into the water supply where they decrease the quality of the water and endanger plants and animals that live there. Because there are so many butts and because they can take up to 5 years to break down, the toxic chemicals add up to a large amount. So, if people have to smoke, they should not throw away the butts but put them in the rubbish bin instead.

    Plastic bags are another common form of litter that is a danger to the environment. There are several reasons for this. They are made from oil and gas, which are non-renewable resources, if they are not recycled, these resources are lost to us. In China, 2 billion plastic bags are used every day. An enormous number of these become litter. This is a huge problem because they last from 20 to 1,000 years in the environment. They float easily in air and water and travel long distances. They find their way to rivers, parks, beaches and oceans. Plastic bags kill up to one million seabirds, 100,000 sea mammals and countless fish each year worldwide. When the animal dies and breaks down, the plastic bag can become free again to kill another animal. It is up to people not to let plastic bags become litter. It would be better if they used fewer and recycled them.

    Cleaning up your cigarette butts and plastic bags would improve the environment. The earth would be a better place because it would be less polluted. And we would know that we were doing something to look after our planet. However, I believe the best solution would be not to smoke or use plastic bags at all.
