Question

They often ________ in Chinese in the English class.

Answer 1

speak
+语言
=
talk
in
+语言
talk,tell,speak,say这是一组近义词。
speak和talk通常用作不及物动词，都有“说话”的意思。在会议上正式发言用speak，其名词为speech
I
know
of
the
man,
but
I've
never
spoken
to
him.
我知道这个人，不过从来没有和他说过话。
He
spoke
at
the
meeting.
他在会上发言了。
注：speak在用作及物动词时，其宾语一般是语言或词语之类的词
He
speaks
English
very
well.
他的英语说得很好。
He
didn't
speak
a
word.
他一句话也没说。
随便漫谈用talk，其名词亦为talk
Human
beings
can
talk,
but
animals
can't.
人会说话，而动物却不会。
They
have
been
talking
since
two
o'clock.
自从两点钟到现在他们一直在谈话。
注：“我想和你聊一聊。”应是：I
want
to
have
a
talk
with
you.
“我有话要和你说。”可说：I
want
to
speak
to
you.
或：I
have
a
word
with
you.
tell表过“讲述”或“告诉”
He
is
telling
an
interesting
story.
他在讲一个有趣的故事。
He's
told
me
everything
about
it.
他把一切都向我说了。
say表示“说”，这是两个及物动词，可以跟直接引语或间接引语作为宾语，它们没有相应的名词
He
said
nothing.
他什么话也没说。
"My
friend
is
an
engineer,"he
said.
他说：“我的朋友是位工程师。”
He
said
that
his
friend
was
an
engineer.
他说他的朋友是位工程师。

Answer 2

speak后面直接跟语言，如do
you
speak
Chinese？不加in
这句话说的是他们经常在英语课上用汉语交谈，所以用talk，in
English是介词短语做状语，表示用英语

Answer 3

答案有误，就是speak
speak
后加in
加语言表示用该语言交谈

Answer 4

你好。有两个可行答案b和c.
考卷出题不严谨。出题人的英语还没有学到家。
语法：
speak
（in）
english
talk
in
english

Answer 5

SPEAK的话，不需要介词IN.我们一般都说：SPEAK
CHINESE。
所以TALK更合理。
TELL
+SB+STH
SAY+STH
