[简答题]I have recently been told that I am one of the millions of Americans who will be afflicted with Alzheimer’s Disease.
Upon learning this news, Nancy and I had to decide whether as private citizens we would keep this a private matter or whether we would make this news known in a public way.
In the past Nancy suffered from breast cancer and I had my cancer surgeries. We found through our open disclosures we were able to raise public awareness. We were happy that as a result many more people underwent testing.
They were treated in early stages and able to return to normal, healthy lives.
So now, we feel it is important to share it with you. In opening our hearts, we hope this might promote greater awareness of this condition. Perhaps it will encourage a clearer understanding of the individuals and families who are affected by it.
At the moment I feel just fine. I intend to live the remainder of the years God gives me on this

[填空题]The workforce have recently been calling for their working hours to be reduced. Many companies have (according)（）switched to a five-day work.

[单项选择]Two techniques have recently been developed to simplify research and reduce the number of nonhuman primates needed in studies of certain complex hormonal reactions. One technique involves the culturing of primate pituitary cells and the cells of certain human turnouts. In the other, animal oviduct tissue is transplanted under the skin of laboratory primates. Both culturing techniques complement existing methods of studying intact animals.
With an in vitro culturing technique, researchers are deciphering how biochemical agents regulate the secretion of prolactin, the pituitary hormone that promotes milk production. The cultured cells survive for as long as a month, and they do not require serum, a commonly used culture ingredient that can influence cellular function and confound study results. One primate pituitary gland may yield enough cells for as many as 72 culture dishes, which otherwise would require as many animals.
The other technique allows scientists to monitor cellu
A. causing tissue changes which block the oviduct
B. shrinking and swelling tissues in conjunction with the menstrual cycle
C. allowing skin tissue to encyst reproductive tissue
D. necessitating abdominal surgery to remove damaged tissue
