Paragraph Practice
Nurse Thatcher was thankful it was Thursday. She knew that on Thursday she had to deliver 33 boxes of thermometers to the North American Athletic Club. They thought that thermometers were necessary for testing the hydrotherapy baths. This was thought to benefit the athletes with arthritis. The athletic trainers required authorization to provide hydrotherapy to the youthful athletes on the three bulletin boards with thumbtacks throughout the athletic club. Rather than risk the health of the athletes, they thoroughly checked the thousands of thermometers to insure their worthiness; otherwise they needed to be thrown away.

TH Exceptions
Although the following words are spelled with a ‘TH’, they are pronounced as a T.TH特例：单词拼写是TH，但发 T 音
Thomas
Thompson
Theresa
Thailand
Thames
Esther
Thyme

voicing the T Sound
If a T falls within two voiced sounds (usually vowels), the T becomes voiced like a D.

注意了：当 T 位于两个浊辅音之间时， 清辅音 T 要浊化，发成浊辅音/D/）。
Examples:
Water Wader (the whole word is voiced)
Better Bedder
Butter Budder

Voiced T Practice
Betty bought a bit of better butter. But, said she, this butter’s bitter. If I put it in my batter, it’ll make my batter bitter.
