易错句子This silk is sheeny than that cotton.

正确表达This silk is sheenier than that cotton.

汉语“比……光亮”用原级形容词，但英语在 than 前必须用比较级；sheeny 是以 -y 结尾的双音节形容词，比较级把 y 变 i 再加 -er，写成 sheenier，所以不能保留原级 sheeny。

易错句子This silk is as sheeny than that cotton.

正确表达This silk is as sheeny as that cotton.

as ... as 结构表示“和……一样”，两个 as 之间用形容词原级，第二个 as 不能换成 than；这里要表达“和那棉布一样光亮”，应说 as sheeny as。

易错句子The car looked sheeny under the sunlight.

正确表达The car looked sheeny in the sunlight.

汉语说“在阳光下”，但英语表示“被阳光照亮”用 in the sunlight（或 in the sun），不用 under the sunlight；under 通常指正下方被某物遮盖，所以这里应把 under 改为 in。
