【题目】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。 “Soon, you're going to have to move out!” cried my neighbour upon seeing the largest tomato plant known to mankind, or at least known in my neighbourhood.
One tiny 9inch 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 sweetsmelling 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 since disappeared under the thick leaves.
Now the task I face in harvesting the fruit is twofold(由两部分组成的). First, I have to find the red ones among the leaves, which means I almost have to stand on my head, and once they are found I have to reach down and under, pick the tomatoes and withdraw my full fist without dropping the_prize_so_dearly_won. Second, I found two fullblown white roses completely hidden as I picked tomatoes in June, but they were weak and the leaves were 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 GonewiththeWind, I'll think about that tomorrow.
(1)What are the requirements for the healthy growth of roses?
A.Frequent pruning and fertilizing.
B.Tomato plants grown alongside.
C.Cages placed around the roots.
D.A lot of care and the right soil.
(2)The writer planted the tomato because ________.
A.there was room for it in the garden
B.it cost only $1.25
C.the soil was just right for it
D.the roses' branches needed to be covered
(3)This year the writer's roses were ________.
A.removed from the rose bed
B.picked along with the tomatoes
C.largely hidden under the tomato plant
D.mostly damaged by too much sunlight
(4)By saying “the prize so dearly won” in Paragraph 5, the writer wants to ________.
A.show the hardship of growing the roses
B.show the difficulty in picking the tomatoes
C.express her liking for the roses
D.express her care for the tomatoes

【题目】B vitamins(维生素)may offer some protection against the effect of air pollution,a new study suggests.

The scientists say the effect is real but stress the limitations of their work.Follow-up studies are urgently needed, they say,in heavily polluted cities like Mexico.

According to the World Health Organization (WHO),over 90% of the world's population live in heavily-polluted areas.The one of the pollutants that is considered the most dangerous is very fine particulate matter, referred to as PM2.5.At around 1/30 the width of a human hair,PM2.5 can go deep into the human lung and contribute to lung and heart health problems in the young and old.

Scientists have long suspected that PM2.5 causes what are termed epigenetic(表观遗传)changes in our cells that can damage our health.Now in this new human trial,an international team of scientists wanted to see if exposure to concentrations of PM2.5 could be mitigated by daily B vitamins.

Ten volunteers were tested initially exposed to clean air and their basic responses were measured.The same volunteers were later tested with large doses(剂量)of B vitamins while exposed to air containing high levels of PM2.5.The researchers found that a four-week B vitamin intake limited the PM2.5 effect by between 28-76% at ten gene locations.They found a similar reduction in effect on the mitochondrial DNA,the parts of cells that produce energy.

However,the researchers caution that their study,while observing a real effect,has limitations.As well as the small number of participants,there was little information on the size of the B vitamin dose that caused the response.

1What is the main idea of the text?

A. B vitamins may fight against PM2.5.

B. PM2.5 can lead to epigenetic changes.

C. Further studies should be done on PM2.5.

D. Exposure to PM2.5 is more and more serious.

2Which can replace the underlined word "mitigated" in Paragraph 4?

A. measured B. ignored

C. reduced D. observed

3How many limitations does the text mention about the new study?

A. 2. B. 3.

C. 4. D. 5.

4How does the writer of the text like the new study?

A. He believes it deeply. B. He criticizes it strongly.

C. He thinks it needs testing again. D. He shows no opinion about it.
