【題目】
Germs are very small living things. They are so small that we cannot see them unless we use a microscope. They are found in all kinds of places, all over the world. There are four main types of germs that they can invade (侵入) plants, animals and people, and sometimes they can make us sick.
Bacteria (細(xì)菌) live just about everywhere on earth. Not all bacteria are bad. Some of them are good for our bodies. They help us keep things in balance. Good bacteria live in our bodies and help us use the nutrients in the food we eat and make waste from what's left over. We couldn't make the most of a healthy meal without these important helper germs! On the other hand, there are several types of bad bacteria, including those that cause sore throats.
Viruses (病毒) need a host to keep living. They need to be inside a place of a living plant or animal, including humans, or even inside a bacterium! Whatever a virus lives in is called its host. Once a virus finds the perfect host, the goal is to reproduce and spread. Viruses are pretty tricky because they can change quickly to fit a new environment. When viruses get inside people's bodies, they can spread and make people sick.
Fungi (真菌) are kind of like plants. Unlike other plants, fungi cannot make their own food from soil, water, and air. Fungi love warm and wet places. Most fungi are harmless. The kind that can grow on your skin can be treated. It probably won't hurt you. But it really makes you uncomfortable!
Protozoa (原生動(dòng)物) are extremely small. Most of them live in water. Some protozoa actually eat bacteria and they are good because they also eat the waste of other small living things. Some protozoa are bad, and they live off of other living things, sometimes humans. For example, if a person drinks unclean water, protozoa may cause health problems.

【題目】
A city without cars would be very strange, right? But Venice is such a city.
Venice is in the northeast of Italy. It wasn't built on land, like Beijing or Shanghai, but on more than 110 islands.Seawater is everywhere around the city.
Even so, travel isn't difficult. The waterways have always been the best way to get around. There are 117 waterways and more than 400 bridges that can guide you where you want to go.People in Venice move from place to place by boat.
Water makes the city special, but it is also a big problem. Sometimes tourists will have such strange experiences. One moment they walk across the Rialto Bridge, and there’s nothing special. But when they come back to the bridge an hour later, it’s underwater and everyone is wearing rain shoes.
Once, people used too much underground water. This made the city get lower little by little. Now the city has gone down by 23 centimeters. Another problem is the rising seawater. The temperature has risen over the years. This has made the ice of the Arctic Ocean melt. Every year, high waters hit the city in autumn and winter. When a lot of water comes, more than half of the city is underwater.
Scientists are trying different ways to stop the city from getting even lower. The Italian government has asked some of Italy’s biggest companies to build the MOST project, which was planned to be build under the seawater to stop the rising water. Anyway, this project is helping solve the problem.
【1】Which is the best way to travel in Venice?
A.400 bridges.B.Taxis and cars.C.The waterways.D.Boats and rain shoes.
【2】What doesn’t cause Venice to get lower and lower?
A.The ice of the Arctic Ocean melt.B.Seawater is everywhere around the city.

C.Scientists can solve the problems easilyD.Some possible ways help to solve the problem.
【4】What’s the best title of this passage?
