3 . The worldwide 20th century “Green Revolution”, which saw huge year-by-year increases in global grain yields (产量),was fueled by the development in the 1960s of new high-yielding dwarfed (矮小) varieties known as Green Revolution Varieties (GRVs).

These dwarfed GRVs are common all over the world in today’s wheat and rice crops. Because they are dwarfed, with short stems, GRVs devote relatively more resources than tall plants to the growth of grains rather than stems, and are less likely to suffer yield losses from wind and rain damage. However, the growth of GRVs requires farmers to use large amounts of nitrogen fertilizers (氮肥) in their fields. These fertilizers are costly to farmers and cause extensive damage to the natural environment. The development of new GRVs combining high yields with reduced fertilizer requirements is thus a global agricultural goal.

Researchers at the University of Oxford and the Chinese Academy of Science have discovered for the first time a gene that can help reach the goal. Comparing 36 different dwarfed rice varieties, the researchers identified a novel natural gene that helps increase the rate at which plants make use of nitrogen from the soil. This gene, called GRF4, can increase the amount of a protein (蛋白质) in plant cells. GRF4 is actually a promoter that encourages the activity of other genes—genes that promote nitrogen uptake (摄入). Professor Harberd said, “Increasing GRF4 levels could contribute to an increase in the grain yields of GRVs, especially at low fertilizer input levels.”

The researchers say the latest rice variety containing GRVs should now become a major target for farmers in increasing crop yields and fertilizer use efficiency, with the aim of achieving the global grain yield increases necessary to feed a growing world population at a reduced environmental cost. It is very urgent at the moment.

Professor Harberd added, “This study is an example of how studying fundamental science objectives can lead rapidly to potential solutions to global challenges. It shows how the discovery can enable chances for food security and future new green revolutions.”

5 . Each year on World Book Day, all the students and teachers in my kids’ primary school dress up as book characters and stage a parade (游行) through the Victorian schoolyard, bringing great happiness to the children.

Yet I am rather disheartened by how my fellow parents look at World Book Day. “It’s too competitive!” “Way too much effort!” My fellow parents are missing the point.

World Book Day should be a wonderful celebration of stories and the love of reading. British children are reading less than ever before. Just one in four reads each day, according to a survey done by the National Literacy Trust on World Book Day.

We need World Book Day. We need a day to celebrate the pleasure to be found in reading. But this festival has changed in recent years because we’re just not playing by the rules.

Among the news stories I’ve read recently, parents compete to see who has made the best costumes (化装服) for their kids. We’re overlooking the point of the day: to celebrate books. So, as a step to correcting things, let’s first make sure our children all continue to have access to great books — at school, at libraries and at home.

And then, let’s read them. A few weeks ago, I started a new routine (日常事务) in my house in which we must all read together for half an hour. Ifs not very difficult; we’ve been managing it about once a week. My husband, our eight-year-old and I love it; my six-year-old has more trouble staying focused. But just this morning he crawled into bed with me with a book under his arm and we read for five minutes, silently side-by-side, before the morning rush began.

Sharing books with children is life’s greatest joy. Don’t let that get lost in the overexcitement of fancy dress.

1. What happens at the school of the author’s kids on World Book Day?

A．Teachers hold book shows.

B．Students read in the schoolyard.

C．Students dress up in special clothes.

D．Teachers hold reading competitions.

2. What does the survey done by the National Literacy Trust show?

A．Many British children are weak in reading.

B．Few parents read together with their children.

C．Many British children spend little time reading.

D．Most parents have a low opinion of World Book Day.

3. What does the underlined word “overlooking” in Paragraph 5 mean?

A．Doubting.	B．Failing to consider.
C．Changing.	D．Beginning to get.

4. The text mainly wants to tell us parents should ______.

A．take World Book Day as a reminder to read with their kids
