影响地球气候

亚寒带树木的年轮有规律的疏密变化与黑子11年的活动周期相对应；黑子活动高峰年，气候反常的几率增多，黑子活动的低峰年，气候状况相对平稳。

世界各国和我国都十分重视对太阳活动的观测和预测，力图把太阳活动可能造成的不利影响降到最低程度。

扰乱地球电离层

人阳活动增强时发出的电磁辐射和高能带电粒子流，强烈干扰地球高空的电离层，影响无线电短波通信，甚至会使各类无线电通信产生短时间的中断现象。

干扰地 球磁场

当太阳活动增强时，来自太阳的高能带电粒子流，会干扰地球磁场，产生磁针剧烈震动而不能正确指示方向的“磁暴”现象

产生极光

高能带电粒子高速冲进两极地区的高空大气，并与那里的稀薄大气相互碰撞会产生淡绿色、红色或粉红色的光带或光弧，叫极光

自然灾害

地球上许多自然灾害的发生与太阳活动有关，如水旱灾害等。

A garden that’s just right for you

Have you ever visited a garden that seemed just right for you, where the atmosphere of the garden appeared to total more than the sum(总和) of its parts? 1 . But it doesn’t happen by accident. It starts with looking inside yourself and understanding who you are with respect to the natural world and how you approach the gardening process.

● 2

Some people may think that a garden is no more than plants, flowers, patterns and masses of color. Others are concerned about using gardening methods that require less water and fewer fertilizers(肥料). 3 . However, there are a number of other reasons that might explain why you want to garden. One of them comes from our earliest years.

●Recall(回忆)your childhood memories

Our model of what a garden should be often goes back to childhood. Grandma’s rose garden and Dad’s vegetable garden might be good or bad, but that’s not what’s important. 4 —how being in those gardens made us feel. If you’d like to build a powerful bond with your garden, start by taking some time to recall the gardens of your youth. 5 then go outside and work out a plan to translate your childhood memories into your grown-up garden. Have fun.

A. Know why you garden

B. Find a good place for your own garden

C. It’s our experience of the garden that matters

D. It’s delightful to see so many beautiful flowers

E. Still others may simply enjoy being outdoors andclose to plants

F. You can produce that kind of magical quality in your own garden, too

G. For each of those gardens, writer down the strongest memory you have

Five secrets to living a sunshine life

Don’t avoid or ignore negativity.

In order to conquer and overcome the negativity, it must be acknowledged. You are in control of your environment and if these negative situations keep making an appearance, it’s up to you to handle them.

Take care of yourself and your needs.

In order to live a powerful and meaningful life, you must love yourself. 1 And this will be reflected in your thoughts and emotional state of mind. Love yourself fully in order to love others fully.

2

Determine what is worth your time and effort and what is not. If situations are bad and beyond repair, it’s time to let go. Are there relationships or friendships that remain damaged but you know are worth the time? 3 Do what you can to find love in situations where it may have been absent in the past.

Give.

Give our time, energy, love and sometimes money to others. 4 So if you can, don’t hesitate to do it.

Focus on things that make us smile, laugh and feel good.

This one is pretty simple. 5 That is, do more of what makes you happy! I truly believe happiness may not come as easily as we wish. In order to go through work and boring responsibilities, we have to actively pursue and engage in beautiful acts of love and kindness. So let’s have a try.

A. Just do MORE of it.

B. Fix them and find peace.

C. Always put yourself first.

D. Mend what’s broken or get rid of it.

E. Determine what is important to you.

F. Mind your actions and how you live each day.

G. Everything we put out into the world comes back to us.

【题目】B

I went nose to nose with a mouse last week, and I’d rather not say who won.

I was cooking when my friend phoned me to help her catch a mouse she had found in the kitchen. The mouse was under the fridge when I arrived. The cat was standing guard, slowly swinging its tail. I tried to put a broom handle beneath the fridge to force it out, but there were too many wires. My friend pulled up a chair at the table and I pulled a chair beside the fridge, armed with a plastic box as my trap. It was a good plan, but as is usually the case, it didn’t go according to plan.

After a while, the mouse put its head out. I knelt down on the floor in front of the fridge and angled the box to create a no-escape trap. The mouse moved out farther and I put the box down immediately. Unfortunately, the only thing inside the box was the mouse’s tail, still attached to the mouse, which was now struggling with its little legs in an attempt to take to its heels. The cat just sat.

The mouse crawled(爬) up on the broom handle I’d used earlier, and we were now eyeball to eyeball. If I’d wanted to — and I didn’t — I could have seized it with my teeth. I shouted I needed something else to get the mouse. My friend handed me another container. I lowered box two over the mouse’s body, still on the broom handle, with its tail still in box one. Despite my two-box move, the mouse escaped and shot back under the fridge.

Shortly after I left, my friend found the mouse. It was bathed in the sunlight in her bedroom. The cat was sitting next to it, enjoying the rays as well. She said they were a cute couple. Learning from my mistakes, she got a box — and a lid — and said the mouse all but jumped in the box and helped her seal the lid. Just a small change brought about an unexpected result.

【1】What does the last sentence in Paragraph 2 suggest?

A. The plan ended in failure.

B. The plan wasn’t worth carrying out.

C. The plan wasn’t carried out properly.

D. The plan proved to be an unexpected one.

【2】What does the underlined part "take to its heels" mean?

A. Go back. B. Stand up.

C. Fight back. D. Get away.

【3】What were the mouse and the cat doing in the bedroom?

A. Enjoying the harmony. B. Comforting each other.

C. Celebrating the escape. D. Appreciating the view.

【4】Who had the last laugh?

A. The author. B. The author’s friend.

C. The mouse. D. The cat.
