　　Soon it may be harder to stop and smell the roses.
　　Growing levels of air pollution from power plants and automobiles have reduced flower fragrances (芬芳) by up to 90 percent in the US.That is compared with pre-industrial levels,a new study has found.
　　The trend is unpleasant for human noses,but may be life - threatening for bees and butterflies.
　　"Many insects find flowers by folowing the scent(香味) produced by those flowers," said the studies lead author Jose D.Fuentes,an environmental scientist at the University of Virginia.
　　"The increasing pollution makes it difficult for them to locate the flowers and feed on their nectar(花蜜)."
　　Scientists have alrady known that flowers produce scent molecules(分子) that bond with pollutants.The process breaks down the plants' sweet smell.
　　With more pollution in the air,the scent molecules don't remain effective as long and travel shorter distances on the wind.
　　The new study suggests that in the mid - 19th century,when pollution levels were first recorded,scent molecules would have been able to travel some 1,000 to 1,200 meters.
　　Today,in the polluted air found downwind of large cities,scentst may only make it some 200 to 300 meters.
　　The report was recently published in the journal,Atmospheric Environment.
　　Bee farmers have reported that bee populations are dropping dramatically in many parts of the world in recent years. Could these missing scents be a factor?
　　Scientists trying to hind the cause of bee population declines have blamed bacteria,pesticides,and even cellphone radiation.
　　Jay Evans,an entomologist(昆虫学者) at the US Department of Agriculture's bee research laboratory,was interested in the new study.But he says he hasn't seen bee behavior that suggests trouble with scents.
　　"Over the last couple of summers I don't think the bees in this area were bringing in much less food,"he said.
　　"It might be that they had to work harder,but it seems like as long as there were bees to collect food they were finding flowers somewhere."
　　But Fuentes fears that the fading smell of flowers may stress insects that are already faced with other threats.
　　"The effects shown in these studies will simply exacerbate whatever the bees are going through right now,"he said.

“Soon, you’re going to have to move out!” cried my neighbor upon seeing the largest tomato plant known to mankind, or at least known in my neighborhood.

One tiny 9-inch plant, bought for $1.25 in the spring, has already taken over much of my rose bed, covering much of other plants, and is well on its way to the front door.

 Roses require a good deal of care, and if it weren’t for the pleasure they give, it wouldn’t be worth the work. As it is, I have a garden full of sweet-smelling roses for most of the year. Bushes must be pruned(剪枝) in early spring, leaving ugly woody branches until the new growth appears a few weeks later. It was the space available in the garden that led me into planting just one little tomato plant. A big mistake.

Soil conditions made just perfect for roses turn out to be even more perfect for tomatoes. The daily watering coupled with full sun and regular fertilizing (施肥) have turned the little plant into a tall bush. The cage I placed around it as the plant grew has long disappeared under the thick leaves.

Now the task I face in harvesting the fruit is twofold; First, I have to find the red ones among the leaves, which means I almost have to stand on my head, and once found I have to reach down and under, pick the tomatoes and withdraw(缩回) my full fist without dropping the prize so dearly won. I found two full-blown white roses completely hidden as I picked tomatoes in June. But they were weak and the leaves already yellow for lack of light.

 Here I am faced with a painful small decision: To tear up a wonderful and productive tomato plant that offers up between ten and twenty ripe sweet tomatoes each day or say goodbye to several expensive and treasured roses. Like Scarlett in Gone With the Wind, I’ll think about that tomorrow.

72．What are the requirements for the healthy growth of rose?

A. Frequent pruning and fertilizing.　　       B. A lot of care and the right soil.

C. Tomato plants grown alongside.　　       D. Cages placed around the roots.

73．The writer planted the tomato because _________.

A. there was room for it in the garden　　　                   

B. the soil was just right for it

C. it cost only $1.25

D. the roses’ branches needed to be covered

74．This year the writer’s roses were __________.

A．removed from the rose bed　　     

B．largely hidden under the tomato plant

C．mostly damaged by too much sunlight　

D．picked along with the tomatoes

75．By saying “the prize so dearly won” in paragraph 5, the writer wants to ________.

A．express her liking for the roses　　

B．show the hardship of growing the roses

C．show the difficulty in picking the tomatoes  

D．express her care for the tomatoes

76．In the situation described in the text, one good thing is that ________.

A．the writer has a daily harvest of tomatoes　

B．the roses cost the writer little money

C．someone will help the writer make the decision

D．the writer can now enjoy both the roses and tomatoes

　  Life on land probably began about 430 million years ago, though it has stayed in the water for perhaps as much as 3,000 million years. When we think of the first thing on land, we probably think of strange animals coming out of the oceans, but in fact no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessity, since then, the plants, are the only form of life that is able to get and store energy.

　　The first plants to stay out of the water were probably certain kinds of algae（海藻）which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once the move to land had been made, however, evolution（进化）happened quickly. By the end of 100 million years, plants had developed their roots（根), and some had got tree -like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.

59．The main idea of the first paragraph is ________.

　　A. life on land probably began 430 years ago

　　B. the first animal on land came from oceans

　　C. there wouldn't have been animals without plants

　　D. plants are the only form of life that is able to get and store energy

60．Which of the following statements is true according to the passage?

　　A. Algae probably has stayed for more than 430 million years.

　　B. It is impossible that algae might be the earliest plant on land.

　　C. Plants get food from animals in the oceans.

　　D. Evolution began after animals appeared on land.

61．Plants with roots appeared about ________ million years ago.

　　A. 430　　　　　B. 300　　　　　 C. 330　　　　　 D. 100

62．According to the passage, ________ appeared earlier than ________.

　　A. apples; oranges　　　　　　　　 B. oranges; apples

　　C. oranges; roses　　　　　　　　　D. algae; wheat
