答案：【解析】：
第4题：本题考查细节理解。根据原文You'll need: Two bananas that look alike and are exactly the same length(长度).可知，实验需要两根看起来一样且长度完全相同的香蕉。
A项“are totally different from each other”意为彼此完全不同，与原文不符；
B项“look alike with the same length”意为看起来一样且长度相同，符合原文；
C项“have the same size but different shapes”意为大小相同但形状不同，原文未提及形状不同，只说看起来一样，与原文不符；
D项“have similar shapes and colours”意为形状和颜色相似，原文强调的是长度相同，而非形状和颜色，与原文不符。
因此，本题选择B。
第5题：本题考查细节理解。根据原文People will usually say the lower banana is the longer one. They may do that because they naturally compare(比较) the two closest curves(曲线) of the bananas.可知，人们认为两根香蕉长度不同是因为他们自然地比较了两根香蕉最接近的曲线。
A项“Because helpers compare the closest curves of the bananas.”意为因为助手们比较了香蕉最接近的曲线，符合原文；
B项“Because helpers see bananas in different ways.”意为因为助手们以不同的方式看香蕉，原文未提及，与原文不符；
C项“Because the bananas used in the experiment are totally different.”意为因为实验中使用的香蕉完全不同，与原文不符；
D项“Because helpers usually think the one closer to them is the longer.”意为因为助手们通常认为离他们更近的那根更长，原文说的是比较曲线，而非距离远近，与原文不符。
因此，本题选择A。
第6题：本题考查主旨大意。根据原文Here's an interesting demonstration (演示) of how you can't always trust what you think you see.可知，这个实验想要告诉我们的是，我们不能总是相信我们所看到的。
A项“Seeing is believing.”意为眼见为实，与原文意思相反；
B项“Practice makes perfect.”意为熟能生巧，与原文无关；
C项“Seeing is not always believing.”意为眼见不一定为实，符合原文；
D项“Think twice before acting.”意为三思而后行，与原文无关。
因此，本题选择C。
【答案】：
4. B；5. A；6. C
