B(2024·苏州考前押题卷)
When we see babies or pets, we can't help gently touching them to show our love. And they give us happy feelings back. But a recent study shows that it's different for plants.
In fact, ▲. That's because touching changes their genes and, even worse, can slow their growth. Professor Jim Whelan of the La Trobe Institute in Australia gave an explanation. “The lightest touch from a human, or even plants touching each other in the wind, leads to a huge gene change in the plant,” Whelan said.
In order to test the idea, the scientists did an experiment on plants. They grew a number of plants to the age of four weeks. Then they touched them with a paintbrush every 12 hours over a 36 - hour period. They found that as a result, the mitochondria(线粒体) in the plants had been partly hurt. The mitochondria are the “powerhouse of the cell”. The mitochondria produce energy for the rest of the cell in both animals and plants. If this “powerhouse” is weakened, the plants will lose a large amount of energy that should have supported their growth. Whelan further explained, “If the touching is repeated, then plant growth is reduced by up to 30 per cent.” According to Science Alert, repeated touching or moving plants will make them grow shorter than others.
Although the touching does have a strong effect on plants, it's not always bad. The researches believe, in some ways, it could be helpful. It may help plants fight against insects and bad weather. The new research findings have led to a deeper understanding of the plants' reply to touching. And the research might also “open up new ways to optimize(优化) growth in the future,” Science Alert reported.

Printing was invented two thousand years ago. And woodblock printing, known as the “living fossil(化石)” in the printing history, still has its traditional charm today.
During the Tang dynasty, Buddhism(佛教) became very popular in China. There was a strong need to produce a large amount of Buddhist scriptures(经文), and copying by hand could not meet the rising demand. Therefore, ancient Chinese craftsmen(工匠) came up with a new way to make lots of copies—woodblock printing. In the Song dynasty, woodblock printed books were quite popular.
Traditional woodblock printing can be divided into four main steps: writing, carving(雕刻), printing, and binding(装订). Each of these steps includes many smaller tasks, and in total, about 30 steps are needed to create a woodblock print.
Carving is at the heart of woodblock printing because this step can make or break the final print. Skilled craftsmen carve characters and pictures to create raised areas or lines. They will hold ink for printing.
One famous example of woodblock printing is the Diamond Sutra(《金刚经》). It's considered the “earliest dated printed book”. This ancient art form not only shows the wisdom of Chinese people but also the beauty of Chinese craftsmanship over the centuries.
Before printing, writing allowed people to share their thoughts. But it is the invention of printing that made knowledge a shareable fruit for humankind.
18. When was woodblock printing first created?
A. Two thousand years ago.
B. In the Song dynasty.
C. Three thousand years ago.
D. In the Tang dynasty.
19. What does the underlined word “demand” in Paragraph 2 mean?
A. Standard.
B. Conditions.
C. Charm.
D. Need.
20. Which English saying can explain the importance of carving?
A. No pains, no gains.
B. A miss is as good as a mile.
C. Burn the candle at both ends.
D. Many hands make light work.
21. What is the main purpose of the passage?
A. To compare different types of printing.
B. To recommend a woodblock printed book.
C. To tell us something about woodblock printing.
D. To explain the importance of ancient craftsmen.
