In the 2013 Nanjing mock exam, it is known that $l$ and $m$ are two different lines, and $\alpha$ and $\beta$ are two different planes. Consider the following statements:

① If $l \subset \alpha$, $m \subset \alpha$, $l \parallel \beta$, and $m \parallel \beta$, then $\alpha \parallel \beta$;

② If $l \subset \alpha$, $l \parallel \beta$, and $\alpha \cap \beta = m$, then $l \parallel m$;

③ If $\alpha \parallel \beta$ and $l \parallel \alpha$, then $l \parallel \beta$;

④ If $l \perp \alpha$, $m \parallel l$, and $\alpha \parallel \beta$, then $m \perp \beta$.

The true statements are \_\_\_\_\_\_\_\_(write down the numbers of all true statements).
