In the past five years, there had been a lot of new buildings in my city. As the result, parks, farms and open spaces have been destroyed. In many new neighborhoods, people live so much far from public transportation (交通), workplaces, stores, and schools that they depend great on their cars. Driving a lot are a waste of time. It also causes more pollutions to the air. So how can we do? First, we should stop all new buildings, that will protect our open spaces. Then we should support a law that providing money for public transportation. This will encourage people leave their cars at home.

I stood on the deck, 1.( stare) at the huge waves. From the moment we had left port and sailed into the English Channel, 2. weather had got worse and worse. Now, lightning flashed across the sky , 3.was covered in dark clouds.
Suddenly, the noise of the engines stopped. The ship slowed, rolling heavily in the rough sea. A voice over the loudspeaker told us 4.(remain) calm — then added that a fire 5.(start) in the engine room, and said that all passengers must go 6.(immediate) to the nearest lifeboat station.
We all ran onto the deck, following the signs to the lifeboats. The ship’s officers arrived, made sure we had life jackets and showed us 7. to put them on.
I looked again in horror at the wild, stormy sea. The 8.(think) of being out there in a tiny boat was 9. (terrify). Minutes passed like hours, until at last a voice announced that everything was 10. control and the danger was over.We all cheered as the engines started again and the ship moved forward into the waves.
I still couldn’t believe it was over, though — not until we had reached port and I was standing on solid ground again!
When I was a young boy growing up in North Dakota, my grandparents were farmers. And I remember the huge garden that my Grandma _______. I promise you it was about 4,000 square metres. Well, _______ it seemed that way to me! She _______ the garden all by hand, with a hoe (锄头) and some water. Each spring the garden took shape from cold flat earth, which she changed through much hard work into rows and hills ready for _______.
I especially remember _______ Grandma plant potatoes. Grandma had _______ potatoes from last year. She stored them with the rest of the harvest in the outdoor cellar (地窖). There vegetables kept safely all _______. When spring came, we _______ last year’s potatoes and planted each piece into hills of soil in the garden. I thought we would never _______ the end of the long hills for planting!
Before long the garden became fully ________ because of sunny days,warmer temperatures and rain. ________ it needed lots of hoeing and watering by Grandma and her helper to have a harvest. It provided vegetables throughout the summer, until the final harvest when ________ weather set in.
By the time Thanksgiving dinner ________, the ground at my grandparent’s farm often would be covered with snow and we’d be ________ for a long winter. Warm inside the house around Thanksgiving dinner, we looked through windows at bare (光秃的) tree branches (树枝) in the ________ garden.

Let's take a minute to think about the water we use. The human body is 60% water and we need to drink lots of water to be healthy. When we are thirsty we just go to the kitchen and fill a glass with clean water.
1.For example, farmers, who produce the food we eat, use water to make the plants grow. When we turn on a light or switch on a TV or a computer we use energy and we need water to produce this energy.
The truth is that we are lucky enough to have clean water whenever we want，but this is not the case for many people around the world.2.That's around one in 10 people in the world. If we drink dirty water，we can catch diseases from the bacteria and become ill. Every year over 500，000 children die from diarrhea(腹泻)from dirty water. That's around 1，400 children every day！Also，in some countries children walk many kilometres every day to get water.3.Therefore，they don't have time to learn how to read or write and don't get an education.
4.On this day every year，countries around the world hold events to educate people about the problems of dirty water and that clean water is something that everyone should have around the world. At one school in the UK，children between the ages of 10 and 15 walk 6km with six litres of water.5.People give them money to do this and all the money helps get clean water to as many people as possible around the world.
A.We use water indirectly too.
B.Every system in our body depends on water to function.
C.It is to inspire people to learn more about water-related problems
D.If children walk many hours a day to get water，they can't go to school.
E.Did you know that around 750 million people do not have clean water to drink？
F.In 1993 the United Nations decided that March 22nd is the World Day for Water.
G.In this way，they know how it feels to walk a long distance carrying heavy bottles.
The past 70 years have been good for corn production in the Midwestern United States, with yields increasing fivefold since the 1940s. Much of this improvement has been credited to advances in farming technology but researchers at Harvard University are asking if changes in climate and local temperature may be playing a bigger role than previously thought.
In a newspaper, researchers find that a prolonged(延长的) growing season due to increased temperatures, combined with the natural cooling effects of large fields of plants, have had a major contribution to improved corn production in the U.S. “Our research shows that improvements in crop yields depend, in part, on improvements in climate,” said Peter Huybers, professor of Earth and Planetary Sciences. “In this case, changing temperatures have had a beneficial impact on agricultural production, but there is no guarantee that benefit will last as the climate continues to change.
Understanding the detailed relationships between climate and crop yields is important as we move towards feeding a growing population on a changing planet. ” The researchers modeled the relationship between temperature and crop yields from 1981 to 2017 across the so-called Corn Belt. They found that as temperatures increased due to global climate change, planting days got earlier and earlier, shifting by about three days per decade. Early planting means the corn has more time to mature before the end of the growing season.
There is also a second, more surprising trend that has benefited corn yields. Whereas the vast majority of temperatures have warmed over the last century, the hottest days during the Midwestern growing season have actually cooled.
The researchers estimate that more than one quarter of the increase in crop yields since 1981 can be attributed to the twin effects of a longer growing season and less exposure to high temperatures, suggesting that the crop yield is more vulnerable to climate change than previously thought.
The researchers also show that the planting and harvest dates farmers currently use is significantly better adapted to the present climate than it would be to climates in earlier decades.
1.What is previously thought to be the reason for the increase of corn production?

2.Why is it important to understand the relationships between climate and crop yield?
A.The climate has a beneficial impact on agriculture.
B.We can change the climate to improve crop yield.
C.We depend on the climate to get food.

3.How many factors that benefit corn yields are mentioned in the text?
A.4. B.3.
C.2. D.1.
4.What is the main purpose of the text?
