The Statue of Liberty, which has been closed to the public since super storm Sandy struck in October, will reopen by July 4.
The Statue of Liberty was presented to the United States by the French people in 1886. It stands at Liberty Island as a welcome to all returning Americans.
It’s five months since the monument and Liberty Island were shut down after the storm.
While the statue itself was not seriously harmed by the storm, several buildings on the island experienced the terrible flood. The way used by ships carrying visitors from lower Manhattan and New Jersey was also destroyed.
“It’s good news, it’s a little late, but at least it’s there, and now we’ll watch like an eagle to make sure this promise is kept,” Schumer told NBC New York.
In January, the government spent $59 million repairing both Liberty Island and nearby Ellis Island, which was also damaged in the storm. But the officers have not announced when Ellis Island will reopen. In November, more than a million art works had to be removed from the museum there because of the storm. The Statue of Liberty is one of the country’s most popular tourist attractions. According to the National Park Service, more than 3.7 million people visit the site every year.

We all enjoy the beautiful show of colours as leaves change each autumn. But did you ever wonder how and why this happens?
Leaves are nature’s food factories. Plants take water from the ground through their roots and take carbon dioxide (二氧化碳) from the air. Plants use sunlight to turn water and carbon dioxide into glucose (葡萄糖). Glucose is a kind of sugar, which plants use as food for energy and growing.
The way plants turn water and carbon dioxide into sugar is called photosynthesis that means “ putting together with light”. A chemical called chlorophyll helps photosynthesis. It gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.
During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories.
As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves. Small amounts of these colours have been in the leaves all along. We just can’t see them in the summer, because they are covered up by the green chlorophyll.
The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples (枫树), glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red colour. The brown colour of trees like oaks (橡树) is made from waste left in the leaves.
It is the mixture of all these things that makes the beautiful colours we enjoy during autumn.
