difficulty
1.with difficulty作“困难地”解，是状语短语，不可用作形容词短语，如可以说We climbed the hill with difficulty，不可说Our climb was with difficulty，该把with difficulty改作difficult。但It was with difficulty that we climbed the hill是可以说的，却不可把with difficulty改作difficult，因为这句是We climbed the hill with difficulty的强势式，那was后面当然用副词或状语短语，不可用形容词或形容词短语。
2.in difficulties（注意用复数形式）作“处境困难的”解，是形容词短语，尤其指金钱上的困难。例如：He was in difficulties. in difficulties for...作“缺乏…的”解，如He was in difficulties for money和He was in difficulties for men（他缺乏帮助他的人手）。注意不可在in difficulties后面接不定式，如不可说He was in difficulties to pay the rent，该说He was in difficulties and unable to pay the rent, and unable不可省。
偶尔in difficulty用作in difficulties解。例如：He was in difficulty.
3.make difficulties和raise difficulties都作“提出反对”或“表示异议”解，注意用复数形式。但说“不提出反对”或“不表示异议”用make（或raise）no difficulties或make（或raise）no difficulty都可以。
4.在have（much，great等）difficulty in...ing和find（much，great等）difficulty in...ing里都用单数形式difficulty，前面都没有a。have difficulty in...ing里的in往往省去。例如：I had little difficulty (in) finding the house. There is（much, great等）difficulty in...ing里的in也有时省去。例如：There was some difficulty (in) getting in touch with the children at home.
5.不可说There is some difficulty for me to understand spoken English该说There is some difficulty in my understanding spoken English。或I have some difficulty in understanding spoken English。
6.注意下面各句里习惯用复数形式difficulties：
- We needed an interpreter because we had language difficulties.
- The enterprise prospered in spite of money difficulties.
- Printing difficulties have delayed the publication of the magazine.
- It is technical difficulties only that they have yet to overcome.
