Thank you, Cari. Fourteen out of fourteen! Wey hey! Offensively triumphalist dance! But I can't take credit for it. I went to secondary school in the 1950s when this is what Eng Lang was about. We did paraphrases and précis and dictation as well. And spelling tests. And my DGS are required to take perfectly good, plain English prose and litter it with unnecessary adjectives and adverbs. And they know they are not learning anything through the activity.
shysal it is a term used when giving directions. For example if someone says "can you direct me to the station, please?" you can reply "Yes of course. You gerund the corner and it's on your left".
I think the first question is rubbish though. How can polluted be an antonym for hygienic? A glass of pure water with a splash of vodka would be polluted by the vodka but it wouldn't be unhygienic. What's wrong with unhygienic anyway?
And I would have thought No 10 is more about correct spelling then grammar! Why does it ask which is grammatically correct. They all sound dreadful anyway. Punctuation is bad, at the very least.
I don't agree that this sentence is conditional: "He thought he might be able to dig a tunnel through the rock".
I think it is passive because it describes a thought. The thought is conditional (possibly – I'd say subjunctive, actually) but the sentence describing it isn't.
