+以下例子已不使用预置网络完成文本分类任务，说明PaddleHub如何完成迁移学习。使用预置网络完成文本分类任务，步骤类似。

 3. `hub.TextClassifierTask`通过输入特征，label与迁移的类别数，可以生成适用于文本分类的迁移任务`TextClassifierTask`。
+4. 使用预置网络与否，传入`hub.TextClassifierTask`的特征不相同。`hub.TextClassifierTask`通过参数`feature`和`token_feature`区分。
+   `feature`应是sentence-level特征，shape应为[-1, emb_size]；`token_feature`是token-levle特征，shape应为[-1, max_seq_len, emb_size]。
+   如果使用预置网络，则应取Transformer类预训练模型的sequence_output特征(`outputs["sequence_output"]`)。并且`hub.TextClassifierTask(token_feature=outputs["sequence_output"])`。
+   如果不使用预置网络，直接通过fc网络进行分类，则应取Transformer类预训练模型的pooled_output特征(`outputs["pooled_output"]`)。并且`hub.TextClassifierTask(feature=outputs["pooled_output"])`。
+5. 使用预置网络，可以通过`hub.TextClassifierTask`参数network进行指定不同的网络结构。如下代码表示选择bilstm网络拼接在Transformer类预训练模型之后。

 文本分类任务Task，继承自[BaseTask](base_task.md)，该Task基于输入的特征，添加一个Dropout层，以及一个或多个全连接层来创建一个文本分类任务用于finetune，度量指标为准确率，损失函数为交叉熵Loss。
 ```python
 hub.TextClassifierTask(

 ```
 
 **参数**
-* feature (fluid.Variable): 输入的特征矩阵。
+
 * num_classes (int): 分类任务的类别数量
 * feed_list (list): 待feed变量的名字列表
-* data_reader: 提供数据的Reader
+* data_reader: 提供数据的Reader，可选为ClassifyReader和LACClassifyReader。
+* feature(fluid.Variable): 输入的sentence-level特征矩阵，shape应为[-1, emb_size]。默认为None。
+* token_feature(fluid.Variable): 输入的token-level特征矩阵，shape应为[-1, seq_len, emb_size]。默认为None。feature和token_feature须指定其中一个。
+* network(str): 文本分类任务PaddleHub预置网络，支持BOW，Bi-LSTM，CNN，DPCNN，GRU，LSTM。如果指定network，则应使用token_feature作为输入特征。
 * startup_program (fluid.Program): 存储了模型参数初始化op的Program，如果未提供，则使用fluid.default_startup_program()
-* config ([RunConfig](../config.md)): 运行配置
+* config ([RunConfig](../config.md)): 运行配置，如设置batch_size,epoch,learning_rate等。
 * hidden_units (list): TextClassifierTask最终的全连接层输出维度为label_size，是每个label的概率值。在这个全连接层之前可以设置额外的全连接层，并指定它们的输出维度，例如hidden_units=[4,2]表示先经过一层输出维度为4的全连接层，再输入一层输出维度为2的全连接层，最后再输入输出维度为label_size的全连接层。
 * metrics_choices("default" or list ⊂ ["acc", "f1", "matthews"]): 任务训练过程中需要计算的评估指标，默认为“default”，此时等效于["acc"]。metrics_choices支持训练过程中同时评估多个指标，其中指定的第一个指标将被作为主指标用于判断当前得分是否为最佳分值，例如["matthews", "acc"]，"matthews"将作为主指标，参与最佳模型的判断中；“acc”只计算并输出，不参与最佳模型的判断。
