解析appear 和 appearance
我们在第一单元中碰到了appear这个单词,现就详细讲解一下这个单词及近义词的辨析。
appear不及物动词,表示“出现”。也是系动词,表示“似乎,显得”,同义词seem, look;反义词disappear。例:his head soon appeared out of the window. 不一会他从窗户里探出头来。
he appears quite well. 他似乎很健康。
appear的用法:
1.appear用作行为动词时,做“出现”解;作连词用,当“似乎”、“显得”讲,与seem同义。但appear与它的表语一起表达的意义往往与事实不相符合。
例:he appeared quite healthy .他似乎很健康。(但实际上不一定健康)
    he appears to be a fool.他似乎是个傻瓜。(但实际上不一定是个傻瓜)
2. appear to sb. + 从句,表示“在某人看来……”。
例:it appeared to me that he is quite well again.  我看他好像又健康了。
3.appear和seem用在否定句中,既可以否定谓语,也可以否定其后面的不定式:
例:he doesn’t appear ( seem ) to like you. / he appears ( seems ) not to like you.
他看上去不喜欢你。
辨析:appear, seem
appear 与 seem 都可以做“看起来”,“好象”解。appear强调外表上给人某种印象,有时含有实质上并非如此的意思。而seem则暗示判断有一定根据,这种判断往往接近事实。
例如:he appears ( to be ) quite old.
