A
Living a healthy lifestyle lies in forming the right eating habits。

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.
Don’t 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，it’s a good idea to eat two healthy snacks beside s 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。

I'd been thinking of taking a course on scuba­diving (水肺潜水） for months，but wasn't sure because I was afraid of snakes! Sea snakes。

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，“It’s gonna be a wonderfu l experience。

Just do it！” Then I went down. My heart beat fast and my ears hurt as I went deeper。

I followed Vita’s 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 didn’t 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.

When Hanadi was 4， her school was destroyed in the civil war。

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 don't 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 Sésamo. 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 IRC’s S arah Smith says。

For the world's 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 they’ve 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：
1．C 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“Wh ile adding these things.。

”可知答案。

2．B 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。

”可知，热水可能会增加体温,从而略微提高新陈代谢率。
