In space, let $l$ and $m$ be two different lines, and $\alpha$ and $\beta$ be two different planes. Then, the correct statements among the following are (fill in the correct numbers):

① If $l \subset \alpha$, $m$ is not parallel to $l$, then $m$ is not parallel to $\alpha$;  
② If $l \subset \alpha$, $m \subset \beta$, and $\alpha$, $\beta$ are not parallel, then $l$, $m$ are not parallel;  
③ If $l \subset \alpha$, $m$ is not perpendicular to $l$, then $m$ is not perpendicular to $\alpha$;  
④ If $l \subset \alpha$, $m \subset \beta$, $l$ is not perpendicular to $m$, then $\alpha$, $\beta$ are not perpendicular.
