（2022·辽宁营口·中考真题）
It is often said, “You can’t live only on air.” But now the Chinese scientists can tell you: Maybe you can.
Recently, some Chinese scientists have developed a new technique（技术）. They turned CO2, one of the main greenhouse gases, into starch（淀粉）.
Starch is the main part of flour（面粉）, rice and corn that we eat every day. Usually, it’s created by plants with CO2, water and sunlight.According to the team’s director Ma Yanhe, it takes the plants nearly 60 steps to produce starch. But now, the team, after six years of hard work, has found a simpler way to do this, with only 11 steps.
“Our study shows that creating something like starch is possible in a lab, and this technology may be helpful in many areas.” said Ma.
The scientists first turned CO2 and hydrogen（氢气）into methanol（甲醇）. Then they pieced（分解）these methanol molecules（分子）into bigger and more complex（复杂的）molecules. Finally the starch was produced.
This method makes it possible to produce food in factories, replacing traditional farming. This will not only help make plenty of food, but also save water and land. It may also help recycle CO2 to deal with climate（气候）change, according to China Daily.
The study can be helpful in space, too. Astronauts may no longer need to worry about their food as they travel in space. They may simply turn the CO2 they breathe out into the food they eat!
21．With a new technique, the Chinese scientists could turn ________ into starch.
A．CO2 B．air C．water D．sunlight
22．Plants can create ________ with CO2, water and sunlight.
A．methanol B．hydrogen C．starch D．greenhouse gas
23．According to the last two paragraphs, the new method may not help ________.
A．produce food in factories B．recycle CO2 to deal with climate change
C．save water and land D．send astronauts into space
24．According to the passage, which of the following is wrong?
A．Producing starch in the lab needs fewer steps now.
B．The new technology may be helpful in many areas.
C．The method will help make plenty of food.
D．The study will be of no help to astronauts.
25．The passage may be from a ________.
A．guidebook B．magazine C．poem D．novel

To Borrow Arrows with Thatched Boats
One day, Zhou Yu ordered Zhuge Liang to make 100,000 arrows（箭）in ten days. Zhou Yu thought it was impossible, but Zhuge Liang said, “Give me three days.” Then he asked Lu Su to lend him 20 boats, and the soldiers put some scarecrows（稻草人）in line on the boats. He reminded Lu Su not to tell Zhou Yu what was happening.
When Lu Su came again to see Zhuge Liang, he found nothing unusual. Nothing happened on the second day, either. In the small hours（凌晨）of the third day, Zhuge Liang invited Lu Su for a boat ride. The 20 boats were tied together with strong ropes. Zhuge’s fleet went towards the camp of Cao Cao. The surface of the river was covered with thick mist（雾）all over. People could hardly see each other on the river. When Zhuge’s fleet got close to the Cao camp before dawn（黎明）, Zhuge Liang ordered his soldiers to shout and beat drums heavily to pretend an attack. But Zhuge and Lu Su only sat inside one boat drinking wine to enjoy themselves.
As soon as the Cao camp heard the shouting and drum beating, they mistook it for a surprise attack by the Zhou Yu camp. Since they could see nobody on the river, they had to order 3,000 soldiers to shoot arrows to stop the unexpected attack. The front of the scarecrows was quickly full of arrows. After a while, Zhuge Liang had his fleet turned around to get the other side of the scarecrows to face the Cao camp. When both sides were full of arrows, the day broke. Zhuge Liang ordered his soldiers to return. The soldiers shouted in excitement, “Thank you, Cao Cao, for your arrows.” After they got back to their camp, they collected more than 100,000 arrows in total from the scarecrows.
36．How many days did Zhuge Liang need to make 100,000 arrows?
A．One day. B．Two days. C．Three days. D．Ten days.
37．The underlined word “feet” probably means _________ in Chinese.
A．船帆 B．甲板 C．船浆 D．船队
38．Who created the idea to get the arrows?
A．Zhou Yu. B．Zhuge Liang. C．Lu Su. D．Cao Cao.
39．The soldiers in the Cao camp shot arrows because _________.
A．the Zhou Yu camp started an attack
B．they could see each other on the river
C．they mistook the shouting and beating for a surprise attack
D．Lu Su beat the drums
40．How did Zhou Yu probably feel after Zhuge Liang returned with over 100,000 arrows?
A．Surprised. B．Bored. C．Tired. D．Lonely.
