Climate change has caused a rise in sea levels. This has increased the amount of salt in fresh water (use) on coastal farms. As a result, farmers are (gradual) unable to use fields close to the sea. However, Marc Van Rijsselberg, a farmer in the Netherlands is now using a (mix) of sea and fresh water (grow) healthy and tasty vegetables.
He teamed up with scientists from the Free University and divided a farm eight negated areas. Separate pipes pumped fresh and sea water, and a computer program created water with eight levels of salinity (含鹽度).
The water levels and the levels of salinity was (control) by computerized measuring devices called “sensors”. Mr. Van Rijsselberg said he was able to harvest vegetables from most of the eight testing areas. He said the vegetables were smaller than grown in fresh water. But he said they also had more sugar and salt, so they tasted much (good).
He found that potatoes grew better than the other vegetables in the combination of sea and fresh water. Mr.Van Rijsselberg said four kinds of these potatoes would be sent to Pakistan thousands of hectares of land (damage) by salinization last year.

【答案】used；gradually；mixture；to grow；into；controlled；those；better；where；was damaged
【解析】本文是一篇說明文，介紹了一種由電腦控制水鹽度的種植蔬菜的裝置。

⑴考查過去分詞。此處是過去分詞作定語，意思是“在海邊農(nóng)場(chǎng)上被使用的淡水含鹽量提高”，故填used。

⑵考查副詞。句中修飾be unable to用副詞，指逐漸地不能使用，故填gradually。

⑶考查名詞。此處由a和of修飾，故用名詞，指一種混合物，故填mixture。

⑷考查不定式。此處是動(dòng)詞不定式作目的狀語，指“為了種植可口的蔬菜”。故填to grow。

⑸考查介詞。divide sth. into...固定短語“把某物分割成…...”，故填into。

⑹考查被動(dòng)語態(tài)。此處指“灌水量和水的含鹽量是被電腦控制的”，此處是被動(dòng)語態(tài)，動(dòng)詞用過去分詞，故填controlled。

⑺考查代詞。those指代前面的the vegetables，用復(fù)數(shù)。故填those。

⑻考查比較級(jí)。此處指“這些蔬菜嘗起來更好”，含有和以前比較的意思，故填better。

⑼考查定語從句。此處where引導(dǎo)的是一個(gè)非限制性定語從句，先行詞是Pakistan，先行詞在定語從句中做狀語，故填where.

⑽考查時(shí)態(tài)語態(tài)。此處指“很多土地被毀”，所以用被動(dòng)語態(tài)；根據(jù)時(shí)間狀語last year，要用一般過去時(shí)態(tài)。故填一般過去時(shí)的被動(dòng)語態(tài)was damaged。

【題目】Scientists think they have answered a mystery: How some ocean creatures got so huge so quickly.

A few million years ago, the largest whales, averaged about 15 feet long. Then seemingly overnight, one type of whale, the toothless baleen whale（須鯨類）became huge. Modern blue whales get as big as 100 feet. Nicholas Pyenson of the Smithsonian Natural History Museum said, “Why is that?” ”It happened in the glance of an evolutionary eye, which makes it harder to figure out what happened,” said Graham Slater, lead author of the study. Their study has suggested an answer: Ice ages in the last 3 to 5 million years started it, changing the oceans and food supply for whales.

The researchers used fossil records of the smaller whales to create a family tree for baleen whales which include blue whales, humpbacks and right whales. Using computer simulations（模擬）and knowledge about how evolution works, they concluded that when the size changes started, the poles got colder, ice expanded and the water circulation in the oceans changed and winds shifted, Slater and Pyenson said cold water went deep and moved closer to the equator(赤道）and then eventually moved back up with small fish and other small animals that whales eat.

Baleen whale, which have no teeth, feed by eating huge amounts of fish they capture. Toothed whales, like sperm whales (抹香鯨), hunt individual fish, so the ocean chants that made food less evenly spread out didn’t affect them as much. But baleen whales hunt schools of fish.

Olivier Lambert at the Royal Belgian Institute of Natural Sciences calls it “a really convincing situation”. But he said the lack of fossils in certain time periods is an issue. As oceans warm from man-made climate change, the seas will be more like it was when the whales smaller and they will have a more difficult time surviving.

【1】What does the author mean by “It happened in the glance of an evolutionary eye” in the second paragraph?

A. The change of baleen whales happened too quickly.

B. The change of baleen whales was too difficult to explore.

C. Researchers paid little attention to the change of baleen whales.

D. Researchers thought the change of baleen whales was unimportant.

【2】What played the key role in baleen whales’ becoming huge?

A. Man-made climate change.

B. Its eating a huge amount of fish.

C. The water circulation in the oceans.

D. The increase of food supply for whales.

【3】What do we know about sperm whales and blue whales according to the text?

A. Sperm whales eat more food.

B. Blue whaler live much longer.

C. Sperm whales prefer to hunt schools of fish.

D. Blue whales usually swallow schools of fish.

【4】What can we infer from the last paragraph?

A. There are no whale fossils now.

B. The whales may become even bigger.

C. Global warming has threatened the whales.

D. Olivier Lamber thinks the study is perfect.

【題目】根據(jù)短文理解，選擇正確答案。
At one time, computers were expected largely to remove the need for paper copies of documents(文件) because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.
It is difficult to measure the quantity of paper used as a result of use of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down ,” says Ted Smith of the Earth Village Organization.
Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.
Does all this mean environmental concerns have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away.
“I guess people believe that the problem is taken care of, because of recycling,” said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity.
The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.
（1）What does the underlined phases mean ________.
A.having a pain in my bone
B.foreseeing something
C.feeling something terrible
D.overhearing something
（2）Hewlett-Packard Co. has decided to develop new technologies because ________.
A.people are concerned about the environment
B.printers in many offices are working overtime
C.small companies need more hard copies
D.they see a growing market for printers
（3）Environmentalists believe one possible way of dealing with the paper situation is ________.
A.to encourage printing more quality documents
B.to develop new printers using recycled paper
C.to find new materials for making paper
D.to plant more fast-growing trees
（4）What would be the best title for the text ?
A.Computers and Printers
B.E-mail and the Business World
C.Internet Revolution and Environment
D.Modern Technology and New Markets
