主语相同,谓语可用逗号隔开,比如：However,the people of all of China's ethnic groups confidently met all challenges,strove to overcome difficulties,fully attained the main targets for economic and social development for the year,and made impressive achievements in reform and opening up and in the socialist modernization drive.
你的例子涉及到形容词的词序问题,如果主语相同,可以这样This is an big red Chinese apple.
apple 是可数名词,前面得加冠词,没有the,得加an.
如果是an apple+单数；
apples+复数
