这一句对不对? 急!

不正確~ :-(

首先 size 是單數 要用 becomes，
另外 small 的比較式是 smaller, 不用 more。

所以，句子可以寫成：

The size of the tablet becomes smaller and smaller.

阿月，我舉個例子：

Your answering skill is getting better and better.

vs

Your answering skill is getting more and more good.

無錯啦～
各位～
其實我當初答呢題問題的時候，我的確有一個矛盾位，但唔係大家擔心果個。

我心裏思疑的是，我應否寫成：
The tablet becomes smaller and smaller.

因為 small 已經是代表size，但我search過，的確有人以此用法，所以我就作出這個答案。

我的懷疑是有道理的，因為我們都知道一個常見的中式英語錯誤。
The color of the ball is red.　＜－－　錯
The ball is red.　＜－－　對

color 這個詞是多餘的，只有說中文的時候才會這樣說。

句子可以有很多方法寫, 例如:

The size of the tablet becomes smaller.
The size of the tablet becomes smaller and smaller.
The size of the tablet is becoming smaller.
The size of the tablet is becoming smaller and smaller.

那句較好, 要看整個情景才知道怎樣寫才是適合, 例如是不是和從前某些情況/時間作比較!

有時只看一句很難說怎樣寫才是最好, 但如果只從grammar角度看問題, 便較容易解釋!

The size of the tablet become more and more small.
The size of the tablets has gradually becoming smaller.

Thank you so much !!!

The size of the tablet becomes smaller and smaller.

但係我在Yahoo!字典找到：

more and more 可當作adverb,
解作"越來越......"
eg. The story gets more and more exciting. 故事愈來愈精彩。

如果佢想表達"越來越細"，唔係啱咩？

ok,
因為exciting有3個音,所以先用more and more.
明了

Your answering skill is getting better and better.

'become' should be 'becomes' (present tense) or 'became' (past tense).
The comparative for small is 'smaller', not 'more small'.
Therefore the sentence should be written as:
The size of the tablet becomes/became smaller and smaller.

I can see the tablet moving in the glass of water. Its size is getting smaller and smaller.
