Here are some of the good habits you can develop when it comes to healthy eating.Drink plenty of water. You must drink at least 8 glasses of water a day. You may need even more water if you are in a hot environment or if you are exercising.Eat breakfast. Breakfast is the most important meal of the day. A recent study has shown that those who eat breakfast will consume (消耗) an average of 100 calories less during the day than their colleagues who skipped breakfast. They will also be able to concentrate better.Dont skip lunch. If you do so, your blood sugar level will drop and your metabolism (新陈代谢) will slow down. When you get home you are starving and eat everything you can find.We all need to snack from time to time，but please choose your snacks carefully. In fact, its a good idea to eat two healthy snacks besides your three main meals. Choose healthy snacks like fruit and vegetables，low fat yogurt, cottage cheese with apple sauce，and so on.Eat your fruit and vegetables. We should eat at least 5 servings of fruit and vegetables a day. Take a piece of fruit for a snack, add some banana and raisins to your favourite breakfast cereal, have a salad for lunch, and eat at least one vegetable at dinner each night. Do not eat your dinner too late. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8 hours. Plan dinner for the week ahead of time and make sure you have everything you need in the house so other family members can get a head start on dinner if you have a late meeting at the office.【语篇解读】本文主要就如何养成好的饮食习惯提出了几条具体的建议。1How many good eating habits are mentioned in the passage?AFive.

Just thinking about it made me sick.But then, I wanted to know why people loved it so much. They all said that under the sea was like a totally different world, yet a beautiful one. And because of that, I decided to take the risk and try to face my fear.So, after taking a private course from my diving instructor, Mbak Vita, I went to Sepa Island with her, to take the final exam.First dive, 12 meters in depth. “What am I doing？”I asked myself. “What if something bad happened？” I tried hard not to panic and told myself to keep a good thought, “Its gonna be a wonderful experience. Just do it！” Then I went down. My heart beat fast and my ears hurt as I went deeper. I followed Vitas instructions closely until I felt comfortable to explore the sea.Suddenly all around me was green. It felt like I was living in a green world! I saw some corals (珊瑚), big ones, and lots of beautiful fish hiding in the sand.I was enjoying the beauty all around me when my instructor waved at me with her hand holding a pink flipper (橡胶蹼). “That flipper looks familiar，”I thought. Yes! That was my flipper! I didnt realize that my right flipper had managed to get away from my right foot!So, that was the first dive. In total, we dove 5 times in 2 days. We managed to dive up to 18 meters in depth. The next dives were smooth and for sure I didn t lose my flipper! I was so happy to see different types of fish swimming in front of me as if I was invisible (不可见的). It was indeed so beautiful and peaceful down there. Now I can see why people love diving under the sea.【语篇解读】本文是记叙文。作者主要讲述了自己第一次下海潜水的经历。5How did the author feel about learning scubadiving at first?AUncertain. BExcited.CComfortable.

Soon after, her family left Syria to live as refugees (难民) in nearby Lebanon. Hanadi joined a school there but was fearful to go. Her experience is not unusual. There are now nearly 25.4 million refugees around the world, according to the United Nations refugee agency. About half are children. Most refugees today are from Syria, when civil war broke out in 2011.To help kids affected by the situation, Sesame Street and the International Rescue Committee (IRC) have teamed up to create a new version (版本) of Sesame Street especially for Syrian refugees, using Muppets (木偶) as teachers, “We dont just want to help children learn letters and numbers，” said Sherrie Westin, who works at Sesame Workshop. “We want to help them feel less alone.”There are more than 150 international versions of Sesame Street. In Germany, kids watch Sesamstrasse, while Mexico has Plaza Ssamo. Each version includes math and spelling lessons. Some characters are the same as in the American version. But other things are different: The Muppets speak the local language and wear local clothes.The new version will include situations that are familiar to Syrian refugee kids. Some of the Muppets, for example, may have been forced to leave their home. “Kids can watch the Muppets work through big problems the kids are dealing with themselves，” the IRCs Sarah Smith says.For the worlds 12 million refugee children, there is little chance to receive good education. And even if kids go to school, they may have fallen behind in their studies. Often, they are traumatized (使受精神创伤) by what theyve been through.The new Sesame Street will meet the public in 2019. Sesame Workshop expects that more than 9 million children will be able to watch the show on a TV, computer, or mobile phone. Hanadi may be one of them.【语篇解读】本文是说明文。少儿节目芝麻街为帮助难民儿童正在制作一个新版系列，让孩子们学习科学知识的同时，获得心灵上的抚慰。9What happened to 4yearold Hanadi?AShe dropped out of school.BShe was injured in the war.CShe fell behind in her studies.DShe became afraid to go to school.答案与解析：D细节理解题。由第一段中的“Hanadi joined a school there but was fearful to go”可知，Hanadi在新学校注册了，但是不敢去上学。10Why was the new version of Sesame Street created?ATo increase the shows popularity.BTo improve education in poor areas.CTo help refugee kids get through hard times.DTo teach kids who cant afford to go to school.答案与解析：C细节理解题。由第二段中的“To help kids affected by the situation”和“We dont just want to help. them feel less alone”可知，制作新版芝麻街是为了在帮助难民儿童学习知识的同时，抚慰他们孤独的心灵，以帮助他们度过艰难的时光。11What do different versions of Sesame Street have in common?AThey all teach math and spelling.BThey were all named Sesame Street.CThe characters are exactly the same.DThe characters wear the same clothes.答案与解析：A细节理解题。由第三段中的“Each version includes math and spelling lessons”可知，每年版本的节目都含有数学和拼写课程。12What can we learn about the new version of Sesame Street?AThe story happens in Syria.BIt will appear on the screen in 2019.CIt will hopefully reach 12 million children.DThe idea was brought up by Sherrie Westin.答案与解析：B细节理解题。由最后一段可知，新版节目将于2019年与公众见面，届时数百万儿童将能够通过电视、电脑或手机观看到该节目。.七选五Drinking hot water regularly can provide many health benefits, including improved digestive health and weight loss. The taste of hot water may not suit your taste. _1_ While adding these things doesnt change all the benefits provided by the hot water, it may cause weight gain, depending on what you add to the hot water.The biggest benefit from drinking any form of water, hot or cold, is providing water for your body. _2_ Meanwhile, it provides a medium for all of the biochemical and metabolic (新陈代谢的) processes in your body.While any type of water can provide your body with enough water, hot water may help you lose weight. Hot water may increase body temperature and therefore increase the metabolic rate slightly. _3_ _4_ Boiled water decreases the number of bacteria (细菌) found in water, making hot water better than room temperature or cold water by reducing your chance of getting infected (感染的). Hot water increases the circulation and decreases the ability for bad bacteria.The theory of Chinese Medicine states that you should drink warm water, about the same temperature as the body. _5_ If you have cold signs such as frequent coldness, thirst, depression, sleepiness, hot water can bring your body back into balance.ATry to drink more water in the morning.BIt helps your body clear waste products.CYou can add some other things like caffeine or sugar.DDrinking water indeed brings lots of benefits to humans health.EHot water may decrease the number of infections you suffer from.FThat is because hot water and cold water affect the balance of your body.GAn increased metabolic rate causes your body to use more calories throughout the day.【语篇解读】本文是一篇说明文。文章主要介绍了饮用热水对身体的好处。答案与解析：1C此空设于段中，是一个过渡句，起到承上启下的作用。根据上文“The taste of hot water.”以及下文“While adding these things.”可知答案。2B此空设于段中，与上文存在逻辑上的指代关系。本空中的it指代上文的“providing water for your body”，故可知答案。3G根据上文的“Hot water may increase body temperature and therefore increase the metabolic rate slightly.”可知，热水可能会增加体温，从而略微提高新陈代谢率。新陈代谢率增加会导致您的身体全天消耗更多卡路里。4E此空设于段首，是一个主题句。下文内容围绕着喝热水可以减少感染这一主题展开的。5F此空设于段中，与上文存在解释关系。中医理论认为你应该喝与身体温度相同的温水。那是因为热水和冷水会影响身体的平衡。
