NEST4 US was born when she realized how much food waste there is，how many hungry people there are，and how simple it would be to use the former to help the latter. "There was a homeless man standing on a corner in D.C.and he was holding a sign that said 'Hungry Need Food'，" she recalls. "So I gave him my lunch and his whole face just lit up.It was so easy，it only took me 30 seconds，and it really helped him."
As NEST4 US took off，with hundreds of volunteers helping to feed thousands of hungry people，Venkat decided to branch out with her volunteer efforts，starting three other branches of NEST4 US.Serving others had become such a way of life for her that she even celebrated her 13th birthday at a homeless shelter，bringing the party to them instead of expecting gifts for herself.
As much as she has helped others，they've helped her too.Not only does she get a lot of joy and personal satisfaction from her volunteer work but running NEST4 US has taught her important life skills like time management，public speaking，writing，and leadership. "What it's really given me is this opinion of putting other people first，" she says.
（1）What can we infer about NEST4 US from the first paragraph？　　
A．Its main aim is to make money.
B．It offers people cheap supplies.
C．It takes in all homeless people.

5、[天一大联考]河南省2025-2026学年下学期高三4月联考(HN202604)语文答案

11、气凝胶是一种在航天领域广泛使用的新材料，如图所示是某种气凝胶质量与体积的关系图象，则其密度为　　kg/m3；假设建造一座宇宙空间站需使用气凝胶400m3，则这些气凝胶的质量是　　kg。由此可见，气凝胶应用在航天领域的原因之一是　　。
【答案】3；1200；密度小。
【解析】由图象可知，当m＝15kg时，V＝5m3，该物质的密度：ρ3kg/m3；
根据密度公式得，气凝胶的质量为：m＝ρV＝3kg/m3×400m3＝1200kg；
由此可见，气凝胶应用在航天领域的原因是密度小。
12、(2023·汕头潮南区一模)由不同材料组成的a、b、c三个实心物体，它们的体积与质量的关系如图甲所示，则密度最大的是________(选填“a”“b”或“c”)物体，它的密度是________ kg/m3。人类发现一颗这样的行星，如图乙所示，这颗行星的体积约为地球体积的4倍，质量约为地球质量的4.5倍。若已知地球的平均密度为5.52 g/cm3，则这颗行星的密度约为________ g/cm3。
【答案】c　2×103　6.21
