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, transporting 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.

1.What would be the best title for the passage?

A. Old Trees Communicate Like Humans

B. Young Trees Are In Need Of Protection

C. Trees Contribute To Our Society

D. Trees Are More Complex Than You Think

2.In Simard’s opinion, trees　　　　　 .

A. protect their own wealth　　 B. depend on each other

C. compete for survival　　 D. provide support for dying trees

3.We can learn from the passage that　　　　　 .

A. if “mother trees” are cut down, the survival for the entire forest will be affected

B. “mother trees” are usually of no use to other trees

C. Charles Darwin had the same thought as Simard

D. people know much about the complex “tree societies”

It comes as no surprise that exercise is good for your health. Positive changes happen to your body before, during, and after a workout. 1.

Build up your body

There are quite a few scientific reasons to do strength training. It makes muscles (肌肉) bigger and bones stronger, thus lowering the risk for certain diseases. Running is an easy but effective way to help build your muscles. 2. But a recent study found that a short run can benefit the legs in the short term. And for now, experts say running has more benefits than risks.

Improve your brainpower

Exercise can help your brain, not just your body. Physical activity helps brain cells (细胞) grow. 3. That’s because physical exercise quickly increases a person's heart rate and carries more blood to the brain, improving the brainpower.

Establish a mind-body connection

Too much stress can lead to inflammation (炎症).4. But simple mind-body exercises like yoga can not only reduce inflammation but also lower the risk of depression. New research shows they can even change your genes to fight off poor health. Research proves that even just 15 minutes a day of practicing mindfulness seems to do the trick.

5. National guidelines recommend more than two hours of physical activity each week. But science says people who pack that amount into one or two days get about the same benefits. Either way, get moving is the key!

A.It is the body’s painful response to injury and overuse.

B.Mindful exercises can improve your long-term well-being.

C.Then what is the proper amount of exercise you should take?

D.And moving more appears to lower the chances of memory loss.

E.Recent research shows more detail about the benefits of exercise.

F.Exercise can also help people deal better with anger and feel happier.

G.Some believe the activity can damage the knees or cause other injuries.

高一英语七选五中等难度题查看答案及解析

With around 100 students scheduled to be in that 9:00 am Monday morning lecture, it is no surprise that almost 20 people actually make it to the class and only 10 of them are still awake after the first 15 minutes; it is not even a surprise that most of them are still in their pajama’s(睡衣). Obviously, students are terrible at adjusting their sleep cycles to their daily schedule.

All human beings possess a body clock. Along with other alerting systems, this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour. Typically, the preferred sleep/wake cycle is delayed in adolescents, which leads to many students not feeling sleepy until much later in the evenings. This typical sleep pattern is usually referred to as the “night owl” schedule of sleep.

This is opposed to the “early bird” schedule, and is a kind of disorder where the individual tends to stay up much past midnight. Such a person has great difficulty in waking up in the mornings. Research suggests that night owls feel most alert and function best in the evenings and at night. Research findings have shown that about 20 percent of people can be classified as “night owls” and only 10 percent can be classified as “early birds” ------ the other 70 percent are in the middle. Although this is clearly not true for all students, for the ones who are true night owls, this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.

1.What does the author stress in Paragraph 1?

A.Many students are absent from class.

B.Students are very tired on Monday mornings.

C.Students do not adjust their sleep patterns well.

D.Students are not well prepared for class on Mondays.

2.Which of the following is true according to Paragraph 2?

A.Most students prefer to get up late in the morning.

B.Students don’t sleep well because of alerting systems.

C.One’s body clock governs the sleep/wake cycle independently.

D.Adolescents’ delayed sleep/wake cycle isn’t the preferred pattern.

3.Which of the following is closest in meaning to the underlined word “classified”?

A.Criticized B.Grouped C.Organized D.Named

4.What does the text mainly talk about?

A.Functions of the body clock.

B.The “night owl” phenomenon.

C.Human beings’ sleep behaviour.

D.The school schedule of “early birds”.
