Warming-up Exercise
Please read the following phrases in falling tone and rising tone, pay attention to the words containing /ɑ:/ /ɔ/ /ɔ:/ /u/ & /u:/ sounds.
Warming-up Exercise/ɑ:/ a fast car / a large shark / a starved artist/ɔ/ socks and stockings / borrow a novel / clocks and watches/ɔ:/ more and more / on the fourth floor / a short story/u/ look for the cook / woolen socks / stood in the foot/u:/ a new rule / useful tools / stoop by a cool pool
/ɑ:/ /ɔ/ /ɔ:/ /u/ /u:/
There are five back vowels:/ɑ:/ /ɔ/ /ɔ:/ /u/ /u:/
For all of them the tip of tongue is withdrawn towards the soft palate, lip-rounding plays an important part in producing all the back vowels except for /ɑ:/
/ɑ:/The tongue is held very low. The
mouth is opened with no lip-rounding. The sound is like the exclamation “Ah”.
/ɑ:/ is usually read in the following letter or combine letters: a ar al auplant glass class fast basketstar park car parcel hardcalm half palm (l is silent)aunt laugh
Phrases & Sentencesa fast car a starved artista laugh star a starry March nighthalf past nine
The dancing part stopped at half past five.
Arthur didn’t pass the art exam. He laughs best who laughs last. A large army marched past the grassland.
/ɔ/The sound is made with open jaws
and slight open lip-rounding, the back of the tongue is kept very low and far back.
/ / is usually read in the followiɔng letters or combined letters: o a ou aucop lock hot clock novelwant what was watch

John has got a pot of hot water. Lots and lots of clocks and watches
has gone wrong. The robber’s name is Robert.

Advice to StudentsSome students often confuse /ɑ:/ with /ɔ/.
In their pronunciation, part/pɑ:t/ sound like pot/pɔt/. This mistake may be corrected if they round their lips a little.
Many students substitute /ɔ:/ for /ɔ/. In their pronunciation, sport /spɔ:t/ and spot /spɔt/ sound alike. To avoid such a mistake, they should open the lower jaw less wide (about two thirds of the jaw-opening for /ɔ/) and raise the back of the tongue higher.

Advice to Students
Students sometime confuse /u:/ with /u/. Remember the English /u:/ is somewhat relaxed though it is a long vowel. In the pronunciation of /u:/, the lips are more rounded and closed than for /u/. The back of the tongue is raised higher, too.
A Brief Summary of the English Back VowelsThe English back vowels have the
following features in common:The tongue is retracted, the back part is
raised to various levels in the direction of the soft palate.
The tip of the tongue is slightly drawn away from the lower teeth.
For /ɔ ɔ: u u:/ the lips are rounded, but for /ɑ:/ the lips are not.
