拓展训练
一、阅读理解（2022春·浙江杭州·八年级期末）
Jenny is excited to go to school these days. The 13-year-old girl is from South Gate Middle
School in Los Angeles, US. She is taking care of three green abalones (鲍鱼) at school.
The students of Violeta Llamas science class, including Jenny, have cared for the sea animals
since January. The science class has eight teams. Each team takes turns to care for the abalones.
Team Five—Jenny, Alexis, Jennifer and Ricardo—have now got their turn.
The abalones are kept in a box of seawater. Every day, Alexis checks if the water has too
much salt. Too much salt is bad for the health of the abalones. Jenny makes fresh seawater. Then
the four students work together to clean up the waste in the box and give some food to the
abalones.
“Sea life is like a baby. You have to clean them and care for them.” Jennifer said.
Nancy Cruse, a scientist, leads the project. She said the number of green abalones is going
down because people have caught too many of them. She said protecting the sea lives now
depends on the young students.
“The students love taking care of the abalones,” said Llamas.
“Taking care of the abalones could open the door for those who want to be a sea life scientist
or an environment protector,” she said.
The students’ time with the abalones will end this school year. Cruse and a team of volunteerswill record the abalones and then let them return to the sea.
1．Why is Jenny excited to go to school these days?
A．Because she doesn’t have science classes.
B．Because she can take care of the sea animals.
C．Because she can eat green abalones at school.
D．Because she doesn’t have any science homework.
2．What does the underline sentence “Sea life is like a baby” mean?
A．Sea life is very lovely. B．Sea life is very small.
C．Sea life need people to take care of. D．Sea life can clean up their waste.
3．Which of the following is TRUE according to the passage?
A．There are fewer and fewer green abalones nowadays.
B．Jennifer and Ricardo needn’t do anything in their team.
C．The students will take the abalones back home after the project.
D．Nancy Cruse thinks protecting the sea lives depends on scientists.
4．What does the writer of this passage want to tell us?
A．We should clean up the waste. B．We should take the science class.
C．We should be a sea life scientist. D．We should care for the sea animals.
【答案】
1．B 2．C 3．A 4．D
【导语】
本文讲述的是珍妮学校里养了三只鲍鱼，学生们被分成8组，轮流来照顾它们，借此文章
告诉我们应该爱护海洋动物。
【详解】
1．细节理解题。根据“Jenny is excited to go to school these days. The 13-year-old girl is from
South Gate Middle School in Los Angeles, US. She is taking care of three green abalones (鲍鱼)
at school.”可知珍妮最近对上学这么兴奋是因为她可以照顾海洋动物。故选B。
2．词句猜测题。根据“You have to clean them and care for them”可知洋生物就像一个婴儿，
你必须清理它们，照顾它们。所以C选项符合，故选C。
3．细节理解题。根据“She said the number of green abalones is going down because people
have caught too many of them”可知现在绿鲍鱼越来越少了。故选A。
4．推理判断题。根据“She said the number of green abalones is going down because people
have caught too many of them. She said protecting the sea lives now depends on the young
students.”可知近年来由于人类过度捕捞，导致鲍鱼的数量在锐减，所以文章想告诉我们应
该爱护海洋动物。故选D。

【答案】例文：
Dear students,
I am glad to talk about the topic of the class meeting — protect the elephants. Elephants are
the largest mammals on land. They can live as long as 80 years. However, these years the number
of elephants is becoming much smaller, because people cut down forests and elephants are losing
their homes. Also, people kill them for ivory. In a word, elephants are in great danger.
I think we should try our best to protect them. First, we should help make rules to stop people
from killing elephants. Second, we shouldn’t cut down trees. Third, we shouldn’t buy anything
made of ivory.
I think we should play a part in protecting the elephants and helping them have a safe and
comfortable home.
That’s all. Thanks a lot.
