1 . Investing In the Graphite (化石墨) Revolution

December 21^st, 2014

Graphene (石墨烯) is the future. Plain and simple.

Its 200 times stronger than steel, thinner than a sheet of paper, and more conductive than copper.

And that’s not all…

Researchers all over the world are using it for critical advances in a variety of industries. Graphene makes:

·Solar cells — 50x～100x more efficient

·Semiconductors — 50x～100x faster

·Aircraft — 70% lighter

We’re talking about batteries that charge 10x faster and store 10x more power…

Phones and computer displays that bend and fold…

It’s so vital to our future that it’s been named a “supply critical mineral” and a “strategic mineral” by the United States, Japan and the European Union.

Yet only a few companies around the world have access to mineral resource that is required to make graphene. And 70% of supply is controlled by China.

So the setup is perfect for any non-Chinese supply to become an extremely profitable investment, just like rare earths a few years ago.

A new report from the Outsider Club fully outlines the situation:

·What grapheme is used for…

·And why now is the perfect time to invest in this world changing discovery.

2 . Blowing Up Balloons with CO₂

Chemical reactions (化学反应) make for some great experiments. You can make use of the CO₂(carbon dioxide) given off by a baking soda (小苏打) and lemon juice reaction to blow up your balloon!

What you’ll need:

●Balloon        ●About 40ml of water        ●Soft drink bottle

●Juice from a lemon          ●I teaspoon of baking soda

Instructions:

●Before you begin, make sure that you pull the balloon long to make it as easy as possible to blow up.

●Put the 40ml of water into the soft drink bottle.

●Add the baking soda and mix it with water.

●Put the lemon juice in and quickly put the balloon over the mouth of the bottle.

What’s happening?

If all goes well, then your balloon should inflate! Adding the lemon juice to the baking soda creates a chemical reaction and produces CO₂. The gas rises up and escapes (逸出) through the soft drink bottle. It doesn’t, however, escape the balloon, pushing it outwards and blowing it up.

1. Which of the following do you need for the experiment?

A．Two cups.	B．Apple juice.
C．250 ml water.	D．A teaspoon of baking soda.

2. What should you do before the experiment?

A．Heat the water.	B．Drink some juice.
C．Blow up the balloon.	D．Pull the balloon long.

3. What is the purpose of the text?

A．To describe an experiment.	B．To introduce a game.
C．To produce soft drinks.	D．To save some chemicals.

3 . 阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式。

The Amazon rainforest is home to a great     1    (various) of plant life; however, its soil is    2       (surprising) poor in nutrients. In fact, the soil in the region cannot support agriculture for more than a few years. If a scientist is shown a report     3    (list) the nutrients of that soil, he or she will probably think that only desert plants can survive in it! Then why is the soil so poor in nutrients? For one thing, the rainy season has     4     impact on the soil. In this season, the water level can rise to more than 12 meters.     5     the water goes away, it takes away the nutrients in the soil. For another thing, due to the Amazon’s hot climate, it is difficult for the soil     6    (build) enough nutrients. Dead plants and animals     7    (break) down more quickly. The nutrients are soon taken in by the roots of the plants deep     8     the ground. As a result, most of the forest’s nutrients are locked up in the plants     9    (them), thus allowing them to grow at a(n)    10    (believable) speed.
