      PRESENT CONTINUOUS TENSE AND PRESENT
                INDEFINITE TENSE

     To talk about something that generally happens, we use the
present simple tense. When we talk about something that is
happening now, or in the real present, we use the present conti-
nuous tense. We make this tense with the verb to be and the
-ing form of the main verb.
     Example We generally run at 88% of our capacity, but at
the moment we are running at 91%.

      EXERCISE 1. Talking about schedules.
      Complete the following sentences with the correct tenses:
      1) We never __________ 100% efficiency, but this month
we __________ for 98% (get/aim).
      2) Although we generally __________ good results, we
__________ with a new loading system (get/experiment).
      3) At the moment we ________ to balance the plant load, al-
though we always __________ some machines (try/under-utilize).
      4) Because we constantly __________ from stoppages, we
__________ a completely new system (suffer/adopt).
      5) Our experts __________ currently __________ the effi-
ciency of the machines that we most often __________ (meas-
ure/rely on).
      6) We occasionally __________ problems with overloads, so
this month we __________ the job sequence (have/change).
      7) At present the sales department __________ a list of prior-
ities for the jobs we __________ regularly (prepare/perform).
      8) The machines rarely __________, but the welding ma-
chine __________ __________ today (malfunction/malfunction).
      9) We usually _________ 1,000 units per week, but this
month we __________ 6% more (manufacture/produce).
