The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials—carbohydrate（碳水化合物）, protein（蛋白质） and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
(P= protein      C= carbohydrate    F=fat)
【小题1】How many calories are needed to raise the temperature of 5kg of water from 35℃ to 90℃?

Once upon a time, there was an island where all the feelings lived: Happiness, Sadness, Knowledge, and all of the others, including Love. One day the feelings were told that the island would sink, so all built boats and left, except Love. Love was the only one who stayed. Love wanted to hold out(坚持) until the last possible moment.

When the island had almost sunk, Love decided to ask for help.

Richness was passing by Love in a big boat. Love said, “Richness, can you take me with you?”

Richness answered, “No, I can’t. There is a lot of gold and silver in my boat. There is no place here for you.”

Love decided to ask Vanity(虚荣心) who was also passing by in a beautiful ship.“Vanity, please help me!”

“I can’t help you, Love. You are all wet and might damage(破坏) my boat, “Vanity answered.

Sadness was close by so Love asked, “Sadness, let me go with you.”

“Oh…Love, I am so sad that I need to be by myself!”

Happiness passed by Love, too, but she was so happy that she did not even hear when Love called her.

Suddenly, there was a voice, “Come, Love, I will take you.”It was an elder. So thankful and happy, Love even forgot to ask the elder where they were going. When they arrived at dry land, the elder went her own way. Realizing how much was owed(欠) the elder, Love asked Knowledge, another elder, “Who helped me?”

“It was Time, “Knowledge answered.

Knowledge smiled with deep wisdom(智慧) and answered, “Because only Time is able to understand how valuable(珍贵的)Love is.”

Three small fish lived in the sea. When they were very young, their parents died. They had to  15  each other day after day. Finally, they grew up and   16  to swim deeper and further.
One morning, the three fish were   17  to a shallow(浅) water by a big wave(浪). A small boat was taken there, too. It was hard for the fish to go back to the sea because the boat was right in front of them. The largest fish realized that they were   18  , and said they had to find a way to leave there as fast as possible. The second largest fish   19  with his elder brother, but the youngest one did not. He said that there was much   20  for their activities, so he would not worry at all and still swam around   21 .
At last, the largest fish returned to the   22  by jumping over the lowest part of the boat. The second largest fish also succeeded in   23   his elder brother in the other side of water. But the youngest one didn’t follow them and still swam joyfully.
Two hours later, when the sun rose up, the water in the small shallow corner   24 . The fish who did not try to return to the sea died of lack(缺乏) of water.

Saving water is an important part of going green. As water becomes less and polluted more, conservation (保护) becomes more and more important. The less water you use, the less wastewater will end up in our rivers and lakes. Wasting water means that more water needs to be treated and cleaned, a process that requires quite a lot of energy.

As it is said above, cutting down on water usage is one of the most important things you can do for your local environment and the planet as a whole. That is why more green households are going blue: cutting down their water footprint by conserving and harvesting (收获) water.

It may seem like a big concept, but going blue starts with small changes that everyone can make. Something as simple as turning off the tap while you brush your teeth can save a lot of water. Wash your fruits and vegetables in a bowl rather than under a tap to save even more. Make sure that the taps are fully turned off every time you step away from the sink or the shower — all those little drips can add up to a lot of water waste.

Another way of reducing your water footprint is reducing your dependence on the main water supply. Rainwater harvesting can meet a lot of your home’s water needs. Many of us already practice rainwater harvesting in a small way. Collecting water from your gutters (檐沟) is a great way to keep your garden green without running the sprinkler (洒水器).
