Do you think they had their success easily? As “Father of Hybrid Rice”, Yuan Longping got over great difficulties and spent his whole life working to reduce world hunger and helping to feed the country with the largest population.Wu Mengchao, the “Father of Chinese Hepatobiliary Surgery”, focused on saving people’s lives for nearly eighty years. He performed more than 16,000 operations (手术) during his life. Holding the knife for such a long time deformed his fingers. Wu once said, “It would be my greatest happiness if I could work at the operating table until my dying day.”In 1969, in order to solve the problem of treating malaria (疟疾), Tu Youyou, a pharmacologist (药学家) took on the job as head of a research team. She and her teammates performed different kinds of experiments. However, the results were disappointing. Instead of giving up, in 1972, they made it! In 2015, she received Nobel Prize.Thomas Edison, the inventor of the light bulb, believed that every failure was a step towards success. He once said, “If I find 10,000 ways something won’t work, I haven’t failed. I am not discouraged, because every wrong try is another step forward.”Sometimes, their success was a surprise, even to themselv es. The famous scientist Alexander Fleming said, “I certainly didn’t plan to revolutionize (变革) all medicine by discovering the world’s first antibiotic (抗生素). But I guess that was exactly what I did.”Some people only became successful after their deaths. Not like Pablo Picasso who became famous and very rich during his lifetime, the artist Vincent V an Gogh only sold one painting all through his life and that was to a friend. But he kept painting and he painted more than 2, 000 artworks in the following ten years. Now his paintings are very popular and they sell for millions of pounds.One thing all these people have in common is sticking to their goals no matter what.21．What do Yuan Longping and Wu Mengchao have in common?A．They succeeded in solving world problems.B．They achieved a lot in the medical field.C．They spent all their lives serving people.D．They are remembered for their happiness.22．Which of the following statements is TRUE?A．Pablo Picasso became famous after his death.B．Vincent Van Gogh painted 2, 001 artworks in his life.C．Thomas Edison tried 10, 000 ways before he invented the light bulb.D．It took Tu Youyou’s team about 3 years to reach their goal.23．How did Alexander Fleming feel about his discovery of the first antibiotic?A．He did n’t fully realize its importance.B．He didn’t plan to study all medicine.C．He knew exactly what his success meant.D．He felt too tired to stay awake.24．What does the writer mainly want to tell us?A．Not everyone can be successful.B．Great achievements ar en’t made naturally.C．The more difficulties, the better.D．Great hopes make great men.三、语法填空（2022~2023上·广东深圳·八年级统考期末）阅读下面短文，在空格处填入一个适当的词或使用括号中词语的正确形式填空。

hadbetter(常简略为'dbetter)是一固定词组，hadbetter"最好"，用于表示对别人的劝告、建议或表示一种愿望。
其用法有以下几点：
一、hadbetter后面必须跟动词原形。
hadbetter后跟动词原形(即不带to的不定式)，构成hadbetterdosth.句型。
这里的had不能用have来替换。
如：
You'dbettergotohospitalatonce.你最好立即去医院看病。
Tom,you'dbettergotheretoday.汤姆，你最好今天去那儿。
二、主语不论是第几人称，句子不论是什么时态，都要用hadbetter 的形式。
如：
Nowyou(he，we)hadbetterlistentotheteacher.你(他，我们)现在最好听老师讲。
三、hadbetter的否定式。
如：
常用的否定形式是将否定副词not直接放在hadbetter的后面。
如：Youhadbetternotmissthelastbus.你最好不要错过末班公共汽车。
YouhadbetternotleaveforNanjingthedayaftertomorrow.你最好后天不要动身去南京。
注意：否定副词not绝不能放在had的后面。
如：不能说：Youhadn'tbettergo.而应该说：Youhadbetternotgo.
四、在祈使句中，had有时可以省略。
如：
Betternotdoit.最好别做那事。
Betternotwaitforthem.最好不要等他们。
五、hadbetter在表示对别人劝告、建议时，不宜用于与陌生人、长辈及上级的交谈中。
对长辈说话时，最好不用hadbetter。
比较有礼貌的说法是：Itmightbebetterforyou...；
Itwouldbebetterforyou...。
如：
Itmightbebetterforyoutohelpme，Grandpa.爷爷，您最好能帮我一下。
