The Leaning Tower of Pisa was not leaning when it was built in 1173 and it was straight like a pole. It started to shift direction soon after construction because of poor foundation in addition to the loose layer of subsoil(底土). At the beginning, it leaned to the southeast before the shaky foundation started to shift leaning towards the southwest. After the period of structural strengthening in the beginning of 21st century, now the Leaning Tower of Pisa leans at an angle of 3.97 degrees.

In 1178, the shift in direction was observed for the first time when the construction had progressed further to the third floor. The tower was very heavy for the three-meter foundation that was built on a weak area of land.

For compensating(補(bǔ)償) the leaning position, the builders started to construct the upper floors with one side higher than the other one. This caused the tower to lean in the other direction. This unusual structure led to the tower being actually curved. In spite of these efforts, the tower kept on leaning.

The government of Italy started to plan a prevention of the complete collapse of the tower in 1964. However, a request was put forward by the authorities to keep the leaning position because of the tourism industry of the region.

After nearly two decades of careful planning by engineers, historians and mathematicians, the stabilization efforts for the Leaning Tower of Pisa started in 1990. The tower was closed for the general public and the people living nearby moved away. For reducing the total weight of the tower, its seven bells which represented the seven musical notes were removed. The tower was reopened for the general public on December 15, 2001.

In May 2008, after removing another 70 metric tons of earth, the engineers announced that the tower had been finally stabilized and it would remain stable for at least 200 years.

Every morning at 6 am Alan Swallow gets out of bed, has breakfast and reads the paper. And for that he is an unsung hero.

When he reads The Southland Times in the morning, he reads it aloud and records if for people who are visually impaired(受損的).

The Blind Foundation provides its members with the Telephone Information Service(TIS) which has articles from more than 70 newspapers, radio and TV schedules, finance information, public and government notices and updates from the Blind Foundation.

The service had struggled for some time with volunteers because not many people knew about it. Swallow said, “It was fulfilling to know that people were benefiting from what he was doing.”

For Blind Foundation social function organiser Liz Anstice, the opportunity to give back to a foundation that had given much to her, was a nice aspect of the role.

Anstice reformed the social committee group and changed things so people did not get bored. The Christmas celebrations had been so well received members from the Blind Foundation in Balclutha were coming down for them. However, sometimes getting members to the events was a challenge because of a lack of volunteers available to transport them, she said.

No one knows why we sleep,but it’s certain that we need to.People who are prevented from sleeping begin to suffer obvious effects after a few days—they think less clearly,and they fall asleep during the working hours;some may have hallucinations（幻覺）.

Children sleep more than grown-ups---perhaps 14 to 18 hours soon after birth,going down to grow-up levels by early teenage.Sleep patterns also tend to be different in the elderly,who may sleep less at night than they did when younger,find sleep getting more broken,and often make it a rule to sleep during the daytime.
