有那些从句需要和主句的时态一致？

主句与宾语从句的时态，应该呼应，但不必强求一致，要根据句子的意思来定。
1.
如果主句是一般过去时，宾语从句的内容是客观真理，则从句用一般现在时。例如
our
teacher
told
us
yesterday
that
the
moon
goes
around
the
earth.
2.
如果主句是一般现在时，而宾语从句的内容是讲过去的事，就用一般过去时。例如
i
think
i
was
wrong
to
say
that.

主从句时态一致原则是指：1.如果主句是一般现在时态或现在完成时态，从句常根据需要选择适当时态。
如：The
teacher
says
that
he
will
go
to
the
Great
Wall
next
week
.
He
tells
us
that
he
had
an
accident
the
other
day
.2.如果主句是一般过去时态，从句常用过去的某种时态；但从句如果是客观的真理或事实，仍用一般现在时态表达。如：He
said
that
he
would
go
to
visit
the
Great
Wall
the
next
week
.
The
teacher
told
us
that
the
sun
rises
in
the
east
.
