Now satellites are 36 to forecast（预报）the weather. They are in space, and they can 37 any part of the world. The satellites take pictures of the atmosphere（大气），38 this is where the weather forms（形成）. They send these 39 to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say 40 the weather will change.Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier 41 . Perhaps they may find that the clouds have changed during the last few hours. This may mean that the 42 on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.So the weather satellites are a great 43 to the meteorologists. 44 __satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may 45 forecast the weather for a week or more ahead（提前）.36.________________A. help B. to help C. helped D. helping
187. It is hard to track the blue whale, the ocean’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when, with the help of the Navy, they were able to track a particular blue whale for 43 days, monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of all exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second, slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.

BIn the 1500s，the camera was invented．However，in the early 1800s people found a way to make the pictures permanent． Even then，photography was a new field． Most families had their pictures taken by photographers．People did not own cameras because taking pictures and developing the films were too difficult．In 1884 ，George Eastman invented a kind of film．lt could be put into a small camera． The new film was easy to use． So many people began to buy cameras． When they had used up their films people returned their cameras to the factory． There，the films were developed，and pictures were made． More films were put into the cameras． And they were sent back to the owners with their pictures．Today's cameras are much easier to use． Photography has become a hot hobby， There are also many new jobs in this field，especially in news reporting． Newspapers，magazines，and tele-vision all need pictures to tell stories， Photographers help scientists by taking pictures through microscopes and telescopes． Deep-sea divers take pictures of ocean plants and animals． Astro-nauts take their cameras into space． Man finds new uses of the camera every day．( )26． When did people find a way to make the pictures permanent?A． In the 1500s．B． In the 1600s．C． In the 1700s．D． In the 1800s．

资料：There's a good chance that spicy crunchy tuna roll you ordered for lunch doesn't actually contain any tuna at all.That's because 74% of fish sold at sushi venues in the US is mislabeled and often completely different than what's on the menu, according to a 2013 survey from the ocean conservation group Oceana.But new technology could help make the seafood business a bit more transparent. Google is teaming up with Oceana and the aerial and satellite imaging nonprofit SkyTruth to launch Global Fishing Watch this fall, the New York Times reports. The initiative will track and analyze fishing boat practices using satellite technology and, ideally, help ensure that fewer fake or mislabeled fish are swapped in along the way.Seafood providers are also investing in technology to reduce fraud. Boston seafood distributor Red's Best, for example, has increased transparency by selling fish with labels that buyers can scan with their smartphones to access a web page that provides details about the individual fish, including where the fish came from, the New York Times reports.Even if a restaurant serves some real, correctly labeled fish, 95% of the 118 sushi restaurants surveyed by Oceana in cities including New York, Chicago, and Los Angeles had at least one faked sushi item on the menu.Currently, the biggest culprits for fake sushi are snapper （92% misleadingly labeled） and tuna （71%）. White tuna is often swapped for escolar, which is sometimes called the "Ex-Lax Fish, " according to Inside Edition, because it can cause intestinal problems.Roughly 75% of fish labeled snapper isn't even from the snapper family. Because of the predominance of fraud in the supply chain, New York sushi restaurant Sushi Nakazawa refuses to serve red snapper because the risk of fake fish is too high.According to the passage, we can infer that______.A.Sushi restaurants verified by Oceana provide no fake fish.B.it would be better not to eat sushi in America.C.the new technology can help deal with the fake sushi to some extentD.fake or mislabeled fish will no longer exist in the sushi market.
How are we to develop new technology if we can’t study current technology to figure out how to______it?A.improveB.restC.causeD.conceal
