Many of us love July because it's the month when nature's berries and stone fruits are in abundance.These colourful and sweet jewels from British Columbia's fields are little powerhouses of nutritional protection.
Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein).Blueberries are particularly high in antioxidants (抗氧化物质).The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants.As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.
When combined with berries or slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”.For this purpose, select ripe bananas for freezing as they are much sweeter.Remove the skin and place them in plastic bags or containers and freeze.If you like,a squeeze of fresh lemon juice on the bananas will prevent them turning brown.Frozen bananas will last several weeks,depending on their ripeness and the temperature of the freezer.
If you have a juicer, you can simply feed in frozen bananas and some berries of sliced fruit.Out comes a “soft-serve”creamy dessert, to be eaten right away.This makes a fun activity for a children's party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.
1.What does the author seem to like about cherries?
They contain protein. They are high in vitamin A.
They have a pleasant taste. They are rich in antioxidants.
2.Why is fresh lemon juice used in freezing bananas?
To make them smell better. To keep their colour.
To speed up their ripening. To improve their nutrition.
3.What is “a juicer” in the last paragraph?
A dessert. A drink.
A container. A machine.
4.From which is the text probably taken?
A biology textbook. A health magazine.
A research paper. A travel brochure.

In the 1960s, while studying the volcanic history of Yellowstone National Park, Bob Christiansen became puzzled about something that, oddly, had not troubled anyone before:he couldn't find the park's volcano. It had been known for a long time that Yellowstone was volcanic in nature—that's what accounted for all its hot springs and other steamy features.But Christiansen couldn't find the Yellowstone volcano anywhere.
Most of us, when we talk about volcanoes, think of the classic cone (圆锥体) shapes of a Fuji or Kilimanjaro,which are created when erupting magma (岩浆)piles up.These can form remarkably quickly.In 1943, a Mexican farmer was surprised to see smoke rising from a small part of his land.In one week he was the confused owner of a cone five hundred feet high.Within two years it had topped out at almost fourteen hundred feet and was more than half a mile across.Altogether there are some ten thousand of these volcanoes on Earth, all but a few hundred of them extinct.There is, however, a second less known type of volcano that doesn't involve mountain building.These are volcanoes so explosive that they burst open in a single big crack,leaving behind a vast hole, the caldera.Yellowstone obviously was of this second type, but Christiansen couldn't find the caldera anywhere.
Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone.A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up for one of the visitors' centers.As soon as Christiansen saw the photos, he realized why he had failed to spot the caldera:almost the whole park—2.2 million acres—was caldera.The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level.At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans.
5.What puzzled Christiansen when he was studying Yellowstone?
Its complicated geographical features. Its ever-lasting influence on tourism.
The mysterious history of the park. The exact location of the volcano.
6.What does the second paragraph mainly talk about?
The shapes of volcanoes. The impacts of volcanoes.
The activities of volcanoes. The heights of volcanoes.
7.What does the underlined word “blow-up” in the last paragraph most probably mean?
Hot-air balloon. Digital camera.
Big photograph. Bird's view.

California has lost half its big trees since the 1930s,according to a study to be published Tuesday and climate change seems to be a major factor (因素).
The number of trees larger than two feet across has declined by 50 percent on more than 46,000 square miles of California forests, the new study finds.No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles.In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.
Many factors contributed to the decline, said Patrick McIntyre, an ecologist who was the lead author of the study.Woodcutters targeted big trees.Housing development pushed into the woods.Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources (资源).
But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, McIntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.
The loss of big trees was greatest in areas where trees had suffered the greatest water shortage.The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt (融雪).
Since the 1930s, McIntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air,and earlier snowmelt, which reduces the water supply available to trees during the dry season.
8.What is the second paragraph mainly about?
The seriousness of big-tree loss in California.
The increasing variety of California big trees.
The distribution of big trees in California forests.
The influence of farming on big trees in California.
9.Which of the following is well-intentioned but may be bad for big trees?
Ecological studies of forests. Banning woodcutting.
Limiting housing development. Fire control measures.
10.What is a major cause of the water shortage according to McIntyre?
Inadequate snowmelt. A longer dry season.
A warmer climate. Dampness of the air.
11.What can be a suitable title for the text?
California's Forests:Where Have All the Big Trees Gone?
Cutting of Big Trees to Be Prohibited in California Soon.
Why Are the Big Trees Important to California Forests?
Patrick McIntyre:Grow More Big Trees in California.

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 ten 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 diarrhoea (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 6 km 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.

since the1930s。后面具体分析了加利福尼亚州大树的现状、造成大树减少的原因等,A项作为标题
最合适。]
Ⅱ.【语篇解读】
本文是一篇说明文,主要介绍了水的重要性。当前世界上很多人喝不到干净的水,
我们要珍惜水资源。
l1.A[结合上文的The human body is60%water and we need to drink lots of water'和下文的use
water to make the plants grow'"we need water to produce this energy可知,第一段讲述了人类直接用
水,而第二段讲述了人类间接用水,故选A项。]
2.E[结合下文的That's around one in ten people in the world.If we drink dirty water'可知,此处讲述
