题目内容

Every year, millions of Americans see their personal information leak into the wrong hands. Maybe there’s spyware on the their computer, or a service they use suffered a security reach, leaving customers at the risk of exposure. Or perhaps their password is easy to guess.

Don’t fear: You can easily set up proper defenses. Here’s how.

● Clean Your Computer and Smartphone

Before you put new security measures into place, make sure your devices are as spotless as possible. This means installing a good antivirus program and taking the time to clear out any spy — or malware that may have already infected your system. These days, it’s also worth it to make sure your phone is safe from viruses. Iphones are less likely to be targeted by spyware, but Android users should download the Lookout app to scan their devices and ensure everything is as it should be.

● Secure Your WiFi.

It’s fairly easy for potential criminals to gain access to your information if they’re able to share your connection — that’s why you want to be careful when using public WiFi. Even though you put security measures into place a couple of years ago, it’s a good idea to refresh your settings.

● Use passwords

What you’ve heard is true: Passwords should use a variety of special characters, numerals, letters, and cases when possible.

● Check the shopping security

Take care when shopping online. Always check the security symbols when using an online site for shopping. If the lock icon encryption (加密) is not there, do not give out credit details. Also, check that the site is legal — never go to a site from a random email and start shopping online.

Keep a separate credit card just for online shopping. This will make it easier to cancel if something bad does happen and your other credit card for “in real life” can still be used uninfluenced.

Don’t store information on any store’s website. It may be convenient but it’s also a possible loss to you if the site is hacked.

Several years ago, the mayor of Chicago, Illinois, visited Germany, a leader in green roof design. Later he decided to have vegetation planted on Chicago City Hall. Today, the tops of many other buildings also look like parks. In Canada, the Coast Plaza Hotel in Vancouver has a forest on its roof. New York City has an unusual example farm for hydroponics. The farm is on a boat called the Science Barge. Rainwater and river water are used to grow lettuce, tomatoes, cucumbers and peppers. The farm shows the possibilities for designing rooftop systems.

Green roofs are designed to save energy and capture rainwater. Rooftops covered with plants help keep buildings cool. They can extend the life of a roof. And they can reduce water running off into streets and storming water systems.

Experts say green roofs usually do not get much above 27℃. So temperatures might not be a problem for growing. But rooftop gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water.

Earlier in 2008, researchers in Texas reported that green roofs can reduce a building's air conditioning costs by about one?fifth compared to black?top roofs. But they also reported that not all green roofs perform equally well. They found that designs differ in their ability to keep buildings cool and to capture rainwater. The researchers put experimental roofs on top of metal insulated (隔热的) boxes, to recreate green roof conditions. The study compared products from six companies to help businesses understand how to improve their designs. Each rooftop had sixteen different kinds of plants native to Texas. The researchers say the presence of native plants likely helped all the green roofs capture water better compared to sedums. Sedums are plants that need little water and often are used on green roofs. The native plants could take in more water and release more of it to the atmosphere.

A. Sometimes green roofs may break down the house.

B. Not all the green roofs can reduce the building's air conditioning costs equally.

C. Different designs of green roofs have different effects on buildings.

D. Sedums are a kind of plants native to Texas.

4.The experiment is mentioned in the last paragraph ________.

A. to find out how many different plants in Texas

B. to show us how to design green roofs

C. to introduce a kind of roof made of metal

D. to provide proofs to improve the design of green roofs

One thing the tour books don't tell you about London is that 2,000 0f its residents (屠民) are foxes. They ran away from the city about centuries ago after developers and pollution moved in. But now that the environment is cleaner, the foxes have come home.

"The number and variety of wild animals in urban c城市的) areas is increasing," says Corner Jones. A survey of the wildlife in New York's Central Park last year counted 14 kinds of animals. A similar survey carried out in the 1890's counted only five kinds.

Several changes have brought wild animals to the cities. First, the air and water quality in many cities have improved as a result of the 1970s pollution-control efforts. Meanwhile, rural areas have been built up, and many animals have gone to the area outside the centre of a city. In addition, urban wildlife refuges (避难处) have been created. The Greater London Council last year spent $ 750, 000 to buy land and build 10 permanent (永久性的) wildlife refuges in the city. As a result, many birds are now living in the city. By 1970 the birds had died out east of the Mississippi because the DDT had made their eggs too thin to support life.

That year, scientist Tom Cade of Cornell University began raising the birds for release in cities, for cities afforded abundant food.

Cities can attract wild animals without turning them harmful. The key is to create habitats where they are able to live happily. Such habitats can even be useful. In San Francisco, the local government is testing different kinds of rainwater control basins to see not only which ones keep the cleanest water but which will attract the most birds.

1. What is the passage mainly about?

A. 2,000 foxes returning to London.

B. Wild animals living in zoos.

C. Wildlife returning to some larger cities.

D. The great enemy of wildlife.

2. It can be inferred from the passage that

A. Londoners are putting more and more wild animals into their zoos

B. Londoners are happy to see wild animals return to their city

C. Londoners are trying to move wild animals back to the countryside

D. Londoners have welcomed the wild birds, but found foxes a problem

3.According to the passage, the number of species of wildlife in New York's park .

A. is slowly going down

B. is the same as that in other cities

C. doesn't change too much

D. has more than doubled in the last century

4. Which of the following is NOT a reason why wildlife is returning to the cities?

A. There is plenty of food for wildlife in the city.

B. Wildlife enjoys being watched and fed in the cities.

C. More and more special living areas have been built for the wildlife.

D. Air and water quality has improved in the cities.
