by train还是by a train？

一、by train还是by a train？

by后面直接接方式，所以正确的是by train

二、on the train和in the train区别？

区别就是两者意思是不一样具体的不同如下

on the train中文意思是在火车上;火车上;

例句

She reasoned that she must have left her bag on the train.

她断定准是把包落在火车上了

in the train为错误搭配使用

三、take a train和riding a train？

Take在用于交通的时候，多指利用什么什么交通工具。Take a train 是乘坐火车的意思。

Riding是ride的动名词形式，是骑行的意思，显然说riding a train是错误的

四、乘火车:on the train还是in the train？

on the train。

on the train和in the train区别：

一，on the train句中on虽有在…之上之意，但在on之后的thain意为火车，属于交道工具，因此，on可作，乘坐火车讲。它同by the train同意。所以全句应该是，乘坐（这列）火车。

二，in the train句中的in不能解释为乘坐火车。只能解释为，在（这列）火车里。

五、train for造句？

Here comes the train, choo-choo-choo With its whistle loud and blue Steaming down the track so fast Taking us to places vast

Ladies and gentlemen, please stand back The train is leaving on the track All aboard, don't be late Hold on tight, it's time to migrate

Through valleys, over hills The train chugs with all its skills Passing cities, fields, and streams Reality turns into dreams

the train, the train, oh so grand Racing across the land Through tunnels and under bridges Across mountains and through ridges

From sunrise till it's dark the train leaves its mark Bringing people and stories anew From station to station, it's quite a view

the train is like a magic beast Carrying travelers from west to east Its wheels go round and round While the engine makes a joyful sound

the train is here to entertain With its rhythm like a summer rain It's a journey full of delight With every passenger's heart alight

Through rain or shine, it chugs along Singing its rhythmic travel song the train, the train, we adore Always ready for adventure galore

So let's all sing nice and loud Join the train-loving crowd With every verse, we'll come alive the train, forever will thrive

total = output.shape[0]

_,pred_label = output.max(1)

return (pred_label == label).sum().data.item()/total

def train(net,train_data,valid_data,num_epochs,optimizer,criterion):

if torch.cuda.is_available():

net = net.cuda()

time0 = time.time()

for epoch in range(num_epochs):

train_loss = 0

train_acc = 0

net = net.train()

time1 = time.time()

for im,label i

八、look to the train？

中文意思是，看着火车

例句如下，

九、train名词？

train

n.火车; 列车; 列队行进的人(或动物); 队列; 行列; 一系列相关的事情(或行动);

十、by the train对不对？

首先不是by the train，是by train。这两个短语在句中的成分完全不同，by train没有谓语动词，只能作状语，表示去某个地点的方式；而take the train有完整的谓语和宾语结构，在句中作谓语，也可以单独构成祈使句。例子：

I went to Los Angeles by train. /我坐火车去洛杉矶

I took the train to Los Angeles. /我坐上了去洛杉矶的火车

Take the train. /坐火车。（这是一个完整的句子）
