Prepositions and connectors

A clock time uses “at”: at 9 o'clock.

On Monday and in June are the common combinations. The wrong pairs exchange the prepositions without preserving these phrases. Next try: give another day and month.

A surface uses “on”: on the table.

At night is the common phrase used here. In the night can describe something happening during a particular night, but bare in night is not that construction. Next try: compare at night with in the morning.

“it was raining” is the reason → use “because”. (so introduces a result.)

I was tired, so I went to bed gives a result. I went to bed because I was tired keeps the same reason and result with another natural frame. The translation does not require the literal word so.

In the pocket identifies the stated inside location. On and behind describe other positions. Next try: describe a pass resting on a table.

at + clock time, on + day, in + month / year / season.

It rained, so we stayed in links the cause to its result once. Because it rained, we stayed in is another standard frame. The other options double this same link or leave an extra so. A longer sentence can contain because plus purpose so that without this error; check their jobs rather than banning both words.

The late bus is the reason for waiting. The first sentence reverses the causal relation; but marks a contrast rather than explaining it. Next try: express the same relation with result so.

I like winter because I can play in the snow is one option. Because I can play in the snow, I like winter puts the reason first and can also fit. Keep the same reason when changing the order.

The shop closed, so we went elsewhere gives the cause before the result. The other options make our leaving explain the closure. Next try: put because before the shop-closure reason.

On Tuesday morning names the morning of that particular day. In the morning is a different common phrase without a named day. Repair: learn the complete phrase rather than treating morning as an automatic signal for in.

Next Monday normally needs no time preposition in this plan. On Monday is a common phrase, but adding next changes the pattern. Next try: write a plan for this afternoon without inserting at.

The because-clause gives the reason; so that gives a purpose. The sentence does not guarantee the purpose was achieved, and the two links do different jobs. Repair: distinguish a goal from a proven result. Next try: say what evidence would show whether the move worked.

Compare your English with the stated facts and checklist. Repair a real mismatch, or explain why none is present. Several answers can fit. This is written self-review, not an automatic correctness or proficiency result.

At half past eight gives a clock time in this phrase. On and in do not fit the stated clock-time frame. Next try: express the same time with digits.

On March 12th names the date. In March names the month without that date; at does not form this date phrase. Next try: write a different complete date phrase.

In August names the month period. On and at do not form this ordinary month phrase. Next try: name a year using its common time phrase.

Last April normally takes no time preposition in this sentence. In April is a useful month phrase, but adding last changes this pattern. Next try: replace last April with this morning.

This morning normally needs no added time preposition here. In the morning is a different phrase. Next try: give a future plan using next Tuesday.

In the morning is the common phrase for this period. On Tuesday morning would name a particular day, but that is not one of these options. Next try: add a named day and adjust the preposition.

On Friday evening combines a named day with a part of that day. In the evening works without Friday; do not choose from the word evening alone. Next try: write a named day’s afternoon phrase.

At night is a common combination; the at/on/in choices are not a universal measure of duration. In the morning is also standard. Next try: give both phrases without comparing their lengths.

At the weekend is common in British English; on the weekend is common in American English. Neither is universally wrong. Next try: keep one variety consistent in a short plan.

At the museum identifies the location without specifying a gallery or roof. Ask for a more precise spot if you need one. Next try: write a message naming the entrance.

On the bus commonly describes a passenger’s situation; it does not require being on the roof. This use is learned as a whole phrase. Next try: identify why the surface-only shortcut would mislead you.

At locates the colleague at the workplace; in can focus on the inside position. The two descriptions need not contradict each other. Under gives a different relation. Next try: explain which phrase more clearly says inside.

Because gives the broken printer as the reason for choosing another. The second reverses the relation; but adds contrast rather than this reason. Next try: put the reason first with Because.

The closed road is the cause and the different route is the result. The other choices reverse that explanation. Next try: express the same relation with because.

Because the lift was broken, we used the stairs gives a reason clause and a main clause. Adding result so doubles this same link in the other options. Next try: write the equivalent sentence beginning with the lift.

So that we could see states the purpose. It does not prove that the view was clear or describe the seats moving. Next try: add a separate observation if you want to report whether the plan worked.

Or presents alternatives here. It does not require simultaneous actions or claim a causal relation. Next try: write a reply selecting one option.

But marks the contrast between the small room and its good view. It gives neither a cause nor a time. Next try: keep both facts while writing a similar contrast about another room.

On Thursday afternoon is the common named-day combination. In the afternoon works without Thursday; at does not fit this phrase. Next try: write the same plan using next Thursday afternoon without a time preposition.

Because states the reason for moving; so that states a purpose. The message does not prove the purpose was achieved. Next try: add a sentence reporting the actual result without changing the original reason.

Compare your English with the facts and checklist. Revise a real mismatch, or explain why none is present. Several answers can fit. This written self-review does not automatically mark your answer correct or establish proficiency.
