判别用谓语动词或非谓语动词
1.S_e_e_intghe dog came over, our friend ran away. (see)
2._S_ee_ from the top of a hill, and you’ll find the city more beautiful. (see) 3._If__ you_s_e_e_ the city from the top of a hill, you’ll find it more beautiful. (see) 4.T_o_s_e_emore clearly, they came up and got close to it. 5.S_e_e_n_from the top of a hill, our house looks like a car.
根据句子结构判断是非谓语动词还是谓语动词
一个句子（包括主句和从句）通常有一个谓语动词（and 可以并列连接两个谓语动词），分析句子:
如果句子中没有谓语动词，填上谓语动词（注意时态和语 态），
如果句子中已经有谓语动词，则考虑用非谓语动词（注意 判别是动词不定式、现在分词、动名词还是过去分词）
1.She got off the bus, __le_a_v_in_g__ (leave) her handbag on her seat.
2. She got off the bus, but __le_ft___ (leave) her handbag on her seat.
3. She got off the bus, who __l_ef_t_(leave) her handbag on her seat.
4._T_u_r_n___ to the right, and you will find the building you want. (turn)
to have done to have been done
to be doing
不定式时态的用法
1. 不定式的动作与谓语动词同时发生时，或之后发生 用一般式 1) He wanted ___t_o__s_e_e___ (see) you. 2) I hope __to__s_e_e_____(see) you again. 2. 强调不定式的动作正在进行时，用进行式
