Grammar
用现在进行时表示将来
当句子涉及确切的计划、明确的意图 和为将来安排好的活动时, 现在进行 时可用于表示将来。
1. 现在进行时表将来使用的动词常为 趋向性动词和表示位置转移的动词, 常用的有: arrive, come, do, get, go, have, leave, meet, play, return, see, spend, start, stay, wear, work 等。如： How are you going, by boat or by train? I’m meeting you after class.
② 在状语从句中用一般现在时代替 将来时。
If you do that again, I’ll hit you. ③ 用在I bet 和I hope后面, 常用一般
3. Some friends _a_r_e_c_o_m_i_n_g_ (come) to Anne’s birthday party this evening. Anne’s mother _i_s (be) busy _g_et_t_in_g_ (get) ready for the birthday dinner. Anne _is__h_e_lp_i_n_g_ (help) her mother now.
2. 现在进行时常表最近或较近的将来, 句子里常有一个表示未来的时间状语。 如: They’re leaving for Hong Kong this afternoon. What are you doing next Sunday? I’m not going out for dinner this evening.
5. 现在进行时表将来与一般现在时 表将来的区别在于: 用现在进行时表 示将来, 其计划性较强, 并往往暗示 一种意图; 而一般现在时表示将来, 则其客观性 较强, 即通常被视为客观事实, 多指 按时刻表或规定要发生的情况。
如果主语是train, concert, programme 等表示事物的名词, 动词通常用一般 现在时表将来而不用进行时。如： What time does the train to Shanghai leave?
2. The Browns _a_re__g_o_in__g (go) to the North China by train next week. They _a_re__s_ta_y_i_n_g_ (stay) in Beijing for a week. They _a_re__g_o_in_g_ (go) to Xi’an. They _a_re__g_e_tt_i_n_g_ (get) there by air.
练一练
1. Betty _is_l_e_a_v_in_g_ (leave) for Guangzhou by plane at 3:00 this afternoon. Her brother Bob _i_s_s_e_ei_n_g_ (see) her off. It’s half past one now. They _a_r_e_w_a_i_t_in_g_ (wait) for a taxi outside the school gate.
--- My plane is taking off at 9:20, so I must be at the airport by 8:30. 我乘坐的飞机将于9:20分起飞, 所以我必须在8:30之前赶到机场。
(6)一般现在时表示将来时 ① 按规定预计要发生的未来动作, 仅限
于动词come, go, leave, move, start, return, arrive, begin, stay等动词。如: The plane takes off at 10:10. That is, it’s leaving in ten minutes.
(3)be to＋动词原形: 表示按计划要发生 的事或征求对方的意见。如: Are we to go on with this work? (4)be about to＋动词原形, 表示即将发生 的动作, 不与表示将来的时间状语连用。 I was about to go swimming when my guide shouted at me and told me not to do so. 我正要去游泳, 这时向导大声叫我不要去。
3. 表ห้องสมุดไป่ตู้来的现在进行时有时含有 “决心”的意思, 多用在否定结构 中。如：
