1 . For most people, the longest relationship they will have is with their sibling (兄弟姐妹). It’s a shame, then, that we can’t choose them. As children, my younger sister and I were always _________ with each other. I was jealous of her looks and she felt threatened by my academic success. But our rivalry (竞争) was _________ compared to that of some famous siblings.

Take 1940s movie star Olivia de Havilland and Joan Fontaine as an example. The competitive relationship between these sisters is famous in Hollywood. “I married first, won the Oscar before Olivia did. And if I die first, she’ll _________ be angry because I beat her to it,” Joan wrote in her autobiography (自传). Their rivalry became very _________ in 1946 when Olivia won an Oscar. Joan was asked to present the award but Olivia refused to even shake her hand. “They just don’t have much in common,” said one person at the time.

But it’s not just in _________ business where siblings fall out. Businessman Rudolf and Adolf Dassler started making sports shoes in the small German town of Herzogenaurach in the 1920s. Their factory south of the river became very successful but they were always very _________. Adolf, or Adi, was a quiet craftsman while Rudolf was “a loud-mouthed salesman”. _________, in 1948, the brothers fell out permanently. Rudolf moved across the river and set up a rival sports-shoe company, which he called Puma. _________, Adi used the first letters of his name and surname to create his brand—Adidas.

The brothers never spoke to each other again and their rivalry _________ the town. The residents wore either Adidas or Puma and would sometimes refuse to __________ each other. It became a place where you always looked at the __________ someone was wearing before starting a conversation. The brothers died in the 1970s and were buried in the same cemetery—at opposite ends.

But not all successful siblings __________ each other. Top tennis players Serena and Venus Williams have played each other in over major tennis tournament finals, but have always remained the best friends. They played doubles together, lived together, and even had breakfast together before these big matches. “We leave everything on the __________,” Serena once said. “We’re sisters the moment we shake hands at the net.”

So, now that we’re adults, have my sister and I learnt to be more like the William sisters and less like the Dasslers? Well, I’d love to say “yes” but the __________ answer is “not always”. I still hate seeing photos of us together because I still feel inferior (次的) to her. But our rivalry is not as bad as it used to be, and if I feel really jealous, I remind myself: __________ disappears but a sister is for life!
