It is 2026 now. Watermelons are not easy to grow in greenhouses and vertical farms. They grow long vines (藤) and the fruits are too big. Now a mother and her daughter have found a good way to solve this problem.

The girl Delaney is a middle school student. She started this special growing plan with her mom five years ago. After many tries, they finally grew super small watermelons. The two used a special natural way to grow new watermelons. They made the watermelons as small as chicken eggs. A common watermelon is several kilograms, but the new ones are only 80 to 200 grams.

These small watermelons keep all their good points. They taste sweet, have red or orange flesh (果肉) inside, and taste fresh. Their seeds are much smaller. They are very fit for greenhouse growing. They also cut down food waste and are good for people who want just a little to eat. People are now curious about them. They want to know if we can eat their skin directly.

1.1.What makes watermelons hard to grow in greenhouses?

A Short roots.

B Long vines.

C Bad taste.

D Small leaves.

解析：选B。B 细节理解题。文章第一段明确提到“They grow long vines and the fruits are too big”，说明西瓜在温室中难以种植的原因是它们长出很长的藤蔓，果实也太大，直接对应选项B“Long vines”。A项“Short roots”（短根）、C项“Bad taste”（味道差）和D项“Small leaves”（小叶子）在文中均未提及，因此不能作为答案。故选B。

2.2. When did Delaney start the growing plan with her mom?

A In 2021.

B In 2019.

C In 2023.

D In 2025.

解析：选A。A 数字计算题。文章第一句交代现在是2026年，第二段又说Delaney是五年前和妈妈开始这个种植计划，简单计算2026－5＝2021，所以她是在2021年开始的，应选A项“In 2021”。B项2019、C项2023和D项2025则与时间推算结果不符，所以不选。故选A。

3.3. What does the underlined word “They” refer to?

A Chicken eggs.

B Delaney and her mom.

C Middle school students.

D Small watermelons.

解析：选B。B词义指代题。根据第二段前文“The girl Delaney is a middle school student. She started this special growing plan with her mom”以及“The two”，可知Delaney和她妈妈一起开展培育计划，后文这句里的They就近指代前文提到的这对母女二人。故选B。

4.4. What do the small watermelons taste like?

A Sour.

B Salty.

C Sweet.

D Spicy.

解析：选C。C细节理解题。第二段中直接说明了这些小西瓜“taste sweet”，所以它们的味道是甜的，应选C项“Sweet”。A项“Sour”（酸的）、B项“Salty”（咸的）和D项“Spicy”（辣的）在文章中都未曾提到，所以排除。故选C。

5.5. What do people wonder about the small watermelons?

A Their seeds’ size.

B Their selling price.

C If they are safe to eat.

D If their skin can be eaten.

解析：选D。D 细节理解题。文章最后一句清楚指出“They want to know if we can eat their skin directly”，人们好奇的是能不能直接吃这些小西瓜的皮，这与D项“If their skin can be eaten”意思完全一致。A项“Their seeds’ size”前文已经说明西瓜籽小得多，不是人们想知道的内容；B项“Their selling price”文中没有出现；C项“If they are safe to eat”原文说的是能否吃皮，并不是询问整体是否安全，因此不选。故选D。
