Gerund

The gerund takes the same form (ending in -ing) as the present participle, but is used as a noun (or rather the verb phrase introduced by the gerund is used as a noun phrase). Many uses of gerunds are thus similar to noun uses of the infinitive. Uses of gerunds and gerund phrases are illustrated below:

As subject or predicative expression:

• Solving problems is satisfying.
• My favorite activity is spotting butterflies.

As object of certain verbs that admit such constructions:

• I like solving problems.
• We tried restarting the computer.

In a passive-type construction after certain verbs, with a gap (zero) in object or complement position, understood to be filled by the subject of the main clause:

• That floor wants/needs scrubbing.
• It doesn't bear thinking about.

As complement of certain prepositions:

• No one is better at solving problems.
• Before jogging, she stretches.
• After investigating the facts, we made a decision.
• That prevents you from eating too much.

It is considered grammatically correct to express the agent(logical subject) of a gerund using a possessive form (they object to my helping them), although in informal English a simple noun or pronoun is often used instead (they object to me helping them).

Subject

The subject in a simple English sentence such as John runs, John is a teacher, or John was ran over by a car is the person or thing about whom the statement is made, in this case 'John'. Traditionally the subject is the word or phrase which controls the verb in the clause, that is to say with which the verb agrees (John is but John and Mary are). If there is no verb, as in John - what an idiot!, or if the verb has a different subject, as in John - I can't stand him!, then 'John' is not considered to be the grammatical subject, but can be described as the 'topic' of the sentence.

These definitions seem clear enough for simple sentences such as the above, problems in defining the subject arise when an attempt is made to extend the definitions to more complex sentences. For example, in the sentence It is difficult to learn French, the grammatical subject seems to be the word 'it', and yet arguably the 'real' subject (the thing that is difficult) is 'to learn French'. (A sentence such as It was John who broke the window is more complex still.) Sentences beginning with a locative phrase, such as There is a problem, isn't there?, in which the tag question 'isn't there?' seems to imply that the subject is the 'there', also create difficulties for the definition of subject.

At B1 level, English language users are expected to have a basic level of proficiency in the language. They should be able to understand and produce language in simple and routine tasks, and be able to communicate in familiar and routine matters. They should be able to understand the main points of clear standard input on familiar matters and be able to produce simple connected text on topics that are familiar or of personal interest. They are able to express themselves with a degree of fluency, but with some hesitation, and occasional errors in grammar and vocabulary.
