本题为根据汉语提示写单词的基础词汇题,需结合句子的语法结构、语境确定单词的正确形式:第1题需填表位置的介词;第2题需填可数名词复数;第3题需填现在进行时的动词形式;第4题需填名词;第5题需填动词过去式;第6题需填修饰名词的形容词。
【解析】
1. 句意:我们能看到鱼在船下面游。“在……下面”表位置,用介词below,符合语境;

There are lots of forests in some parts of Xizang. To protect them, some scientists from Peking University and some other universities did research on them this year. During the research, they found lots of useful and important trees in them.
In May, 2023, the researchersfound a large number of trees over 85metres high, including 25 trees over 90metres. One of them is 102. 3 metres. And it breaks the Asian record, becoming the tallest tree in Asia. (Thetallest tree found in China last year was83.2 metres.)
They found the record-breakingtree, called the Cupressus torulosa(西藏柏木), at the national nature reserve ofYarlung Zangbo Grand Canyon(雅鲁藏布大峡谷国家自然保护区). The Cupressus torulosa mostly lives in southeastern Xizang. The tree doesn't have a large area to live in and the population of it is small. It is the national first-class protected plant now. With the help of drones(无人机) and a laser radar(激光雷达), the researchers were sure about the 102. 3-metre tree. It is the second tallest tree in the worldafter the one in America which is 115. 85 metres.
The number of tall trees in the world is very small, because they need proper living environment and they must be far away from wind, fire and human activities.
One of the researchers said the tallest tree in Asia can help to research the weather conditions and living environment that trees need so that they can help to save some other endangered plants in the area.
