It was on a warm autumn day that my father and I walk into my new high school. After registered in the classroom, I was taken to my dormitory by the volunteer. Altogether I had five roommates, two of which arrived later. I got to know my new roommate immediately. Although I was quite unwilling to say “Goodbye” to my father, but he had to leave to home. I suddenly realized I had grown up and that I had to look after me and live independently. Not until then I know my senior high school life had real begun.

Most animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership (伙伴关系) which is good for both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.

Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals(珊瑚) of the sea. In their skins they have tiny plants which act as “dustmen”, taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they cannot live normally, the corals will die.

1.We learn from the text that corals depend on plants for______.

A. food B. light

C. oxygen D. comfort

2.Some birds like to sit on a sheep because _______.

A. they enjoy travelling with the sheep

B. they can eat the parasites on the sheep

C. they depend on the sheep for existence

D. they find the position most comfortable

3.The underlined word “they” in the first paragraph refers to ____.

A. birds and sheep B. birds and parasites

C. parasites and sheep D. sheep, birds and parasites

4.What does the second paragraph mainly discuss?

A. Some animals live better together.

B. Some plants depend on each other for food.

C. Some animals and plants develop their relationship easily.

D. Some animals and plants depend on each other for existence

Exposed soil isn’t part of nature’s master plan. Good examples where soil is naturally found with no plants growing in are beneath freshly removed trees, or where the ground has been burnt by a land fire. In these situations bare soil isn’t bare for long; within days seedlings (芽) begin to appear and cover the ground. In a few months’ time, the scar is hardly noticeable.

Unlike these natural examples, ploughed (耕犁) fields and freshly dug gardens are obvious examples created by man. But, left to nature, even these bare soils soon turn green with a large number of tiny seedlings. In fields, gardens and on grasslands, roadside and sports fields, along streets and on paths and pavements, we are constantly battling to stop weeds from growing. All we are doing is stop the recovering powers of nature.

Whenever soil is exposed, weeds act like a kind of medicine to reduce the potentially harmful rays of the sun, so the sooner plant growth covers the soil over again, the better.

Weeds also help to improve the fertility (肥沃) of the soil. Their roots get the soil together, improving its structure and creating a more stable environment in which soil life can grow fast. Those weeds with a deep root draw up plant nutrients from deeper in the ground, making them available to plants growing near the soil surface. Above ground, the stems (茎) of weeds help trap fallen leaves which break down into the soil, adding to the fertility of the soil.

As the soil becomes more fertile, different kinds of plants start to replace the “pioneering” weeds. Bushes move in to take the place by gradually shading them out, followed in turn by trees, which eventually push up through the bushes, finally shading them out too. Fallen leaves from the bushes and trees carry on the job of building soil fertility that was begun by those very first weeds that grew on the bare soil. Then, when one of these mature trees is removed in a storm, leaving a wound of bare soil in the earth, the whole process starts again.

1.When will soil be left bare?

A. A land fire has just happened. B. A young tree is planted in.

C. No one ploughs the land. D. No crops are planted in.

2.Which of the following prevents the bare soil from recovering?

A. Seedlings appearing in gardens.

B. Reducing harmful rays of the sun.

C. Removing weeds from pavements.

D. Replacing plants in sports fields.

3.What can weeds do for the soil?

A. They create soil life.

B. They help improve the soil.

C. They get nutrients from the sun.

D. They break down fallen leaves.

4.How can the soil remain fertile after trees move in?

A. By adding more weeds to the soil.

B. By taking out the weeds constantly.

C. By removing the previous bushes.

D. By making use of the fallen leaves.

Wang Lei and I are neighbours and we go to the same school. We have been good friend since childhood and have a great deal to share with every day. however, one day, Wang Lei copied my homework, which made me such angry that I did not want to befriend with him any long. One Monday morning I run downstairs without realizing it was raining, but there was no time to return home to fetch umbrella. It happened when Wang Lei was just around the corner and offered to share her umbrella with me. He made an apology to me in a gently voice. I forgave him but gave him a hug.

Many people in England are angry that drivers park their cars on the pavements. Cars that are on the pavement prevent people from walking safely down the street. They have to walk into the road to get around the running cars. It’s a lot more difficult for blind people to walk around the town if cars are in their way. A spokesman for a charity told the BBC, “It can be frightening for anyone who is forced to step into a road because the pavement is blocked by a van, car or other badly parked vehicle. Imagine you have to step into a road where you can’t see oncoming traffic.”

A survey on parking in Britain found that 70 percent of people want a ban on parking on pavements. A town south of London has already started a system to get drivers to park in a proper car park. Any motorist who parks on the pavement gets a $115 fine. However, many people say the fines do not work. Local people say car owners ignore the fine and park where they want. One woman said there would soon be a very serious accident because of a car parked on the pavement. She wants her town to be like London, which has strict rules against pavement parking.
