Present simple/present continuous

[Will17]

Hello!

In the following cases, I don't know which to choose: the Present simple or the present continuous. Can you help me?

-(In an email) I attach/am attaching two files.

-(In an email) I send /am sending you my confirmation.

-Do you turn the tap off when you clean/are cleaning your teeth?

-His level is too low. He slows /is slowing down the rest of the group.

Thank you
W

1. 'I (hereby) attach...' is a formal set expression; ''I am attaching" is informal.

2. I am sending... (even formally, the present simple is not used here)

3. & 4: both possible, since the action in question may reasonably be viewed from either a general (simple) or an ongoing (progressive) standpoint. Probably, however, a natural tendency toward verbal concord would make 'clean' slightly more idiomatic that 'are cleaning' in (3).

I use "I have attached", "please find attached <document name>" and "please find <document name> attached."

• I am sending you ...
• Do you turn the tap off when you brush your teeth?
• Do you turn the tap off when brushing your teeth?

The last one, "He slows/is slowing down", I wouldn't use
personally, and should be rephrased, say, maybe, his work (habits) is (are) slowing down the groups' progress, which places emphasis on work rather than on the person.

hi,

Please note I'm not a teacher nor a native speaker;

another alternative for the last one :
He's not at the expected level of performance and that affects the team.

Cheers
