If we observe carefully, we van find that most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census(普查)to colours of more than four thousand kinds of flowers and discovered that only eight of them are black. Why?

As we know, sunlight is formed by seven different kinds of coloured light. The wave length of each light changes, so the quantity of heat in each light changes, too. Flowers, especially their petals(花瓣), are very delicate(纖弱) and prone(易于) to the harm caused by high temperature. Black flowers can take in all the light waves, which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.

That is why red, orange and yellow flowers are very common in nature while black flowers are so rare.

1.We can hardly find black flowers because  _____.

A.they are so weak that it’s difficult for them to grow up

B.there are no black flowers in the world.

C.the petals of black flowers are very delicate

D.they can take in the light of all wave lengths, which make the flowers dry up

2. Sunlight is formed by _____.

A.many different kinds of coloured light

B.three different kinds of coloured light—red, orange and yellow

C.seven different kinds of coloured light

D.four thousand kinds of coloured light

3.The red, orange or yellow light contains _____.

A.less heat than the other lights

B.more heat than the other lights

C.a great deal of heat

D.a little heat

4.“It is a chance in a million” means_____________

A.it is common

B.it is extremely rare

C.it’s lucky

D.it’s impossible

Last Friday my brother and I were driving home and had a fun conversation. So absorbed in our talk, my brother took a wrong turn.
Unfortunately, the wrong turn took us towards a  31 , and we had no way to turn  32 . __33 my brother paid the bridge fee and drove on. He was greatly  34 by his mistake and the needless   35  of $4.
We eventually reached an exit, and as we took it, my brother noticed a young fellow  36 over to the side. He came out of his car and tried to  37 someone. I was busy trying to   38 which way we would go next, but my brother stopped and asked the guy if he needed any  39 And he did. He had a flat tire and needed a tool to get it off.
My brother gave him a wrench(扳手), and then helped him  40 the flat. The young man said that this had been a  41 week for him: earlier he had gotten into a minor car  42 , and now this tire was flat on his way home from work. But he called us “a breath of fresh air’’ and kept   43  us because he really would have been   44  if we hadn’t come along.
After we had finished the job, he thanked us again and pulled out $20 to give us. “No,” my brother said. “We were never  45 to even get on that bridge. We took a wrong turn. But now we know  46  we did. It was to help you. Thank you for turning our mistake into a(n)  47 to serve.”
What I loved most was  48 my brother throughout this process. He was able to turn his mistake into 49 energy to help others even in a negative situation, which could only come from a calm mind and an open  50 .

No one can change the weather. Nobody can control the weather. But if we read correctly the signs around us, we can tell what the more important changes in the weather will be. This way of telling what the weather will be like on the following day or two is called weather forecasting(天氣預報).
For many centuries and in all countries, people have studied the weather and tried to make weather forecasting. Rings around the sun are a sign of coming rain. That many people feel their joints(關節) hurt is a sign of wet weather. Some birds fly high if fine weather is coming, but they fly near the ground if rainy or stormy weather is on the way. If you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. Such rainbows come in the evening. If the stars twinkle clearly at night, then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset is mostly red in colour, then the following day will be fine. If a rainbow appears in the morning, rainy weather will probably come.
Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting.

根據短文內容,從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。
We all know that money can’t buy happiness. No matter how much we earn, or how nice our clothing or cars or toys are, none of it will make us happier. __【小題1】_____ and the sad thing is that it could take us decades of pursuing wealth and luxury(奢侈) items before we realize this.
So what will bring us happiness? ___【小題2】__ these three things have been proven by surveys of hundreds of thousands of people about what they have, what their lives are like, and how happy they are.
_____【小題3】_____ We have a human need to be close to other human beings. Having good, supportive friendships, a strong marriage or close and loving relationships with our family members will make us much more likely to be happy. So take time to stay with your loved ones, to tell them what they mean to you, to listen to them.
Positive thinking can lead to happiness too. In fact, optimism and self-confidence are some of the indicators(跡象)of people who lead happy lives. So remember to get into the habit of squashing(排除)all negative thoughts and replacing them with positive ones.___【小題4】____
The state we enter when we are completely focused on the work or task before us will almost undoubtedly lead to happiness.
