一、阅读理解

1．Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”. Nitrogen（氮） and carbon are shared through miles of underground fungi（真菌）networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons（神经元）in our brains, and when one tree is destroyed, it affects all. Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transportin g important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.

“We didn't take any notice of it.” Simard says sadly . “Dying trees move nutrition into the young trees before dying, but we never give them a chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

English, as we all know, is considered as the universal language. It is spoken all over the world. However, you will also notice that people all over the world are using different types of English. Let’s take a closer look at these two popular types: UK and US English. Even if both types of English are wildly used, there are some differences that will be worth knowing to find out the type of English that you are using.

US English is what we know as the American English which is wildly used in the United States. UK English, on the other hand, is known as the British English. Some also call it the BBC English since it is the English used by British reporters, and another name for it is the Qu een’s English.

In terms of vocabulary, some words in US English may mean something different in the UK English. For example, the word biscuit for the British means baked sweet or salty cake that is hard when baked and softened over time; while in the US it is a quick bread served with salty foods.

With regards to pronunciation, American English is more nasal (鼻音的). Stress (重音) is also another difference to consider. Just like in the word princess, British stress the second syllable (音节) while Americans stress the first.

Spelling is another area of difference. American English spelling is more simple. Example
