Paragraph 4: …. Another class of desert plant is the phreatophyte. These have adapted to the environment by the development of long taproots that penetrate downward until they approach the assured water supply provided by groundwater. Among these plants are the date palm, tamarisk, and mesquite. They commonly grow near stream channels, springs, or on the margins of lakes.
What do “the date palm, tamarisk, and mesquite" have in common?
A.They are always found together.
B.They depend on surface water provided by streams, springs, and lakes.
C.They are phreatophytes.
D.Their roots are capable of breaking through hard soils.
但是大家不要忘了，在定位句中有這么一個(gè)表達(dá)，among these plants.. 這里我們要注意，既然出現(xiàn)了代詞，就務(wù)必要搞清楚這個(gè)代詞的指代內(nèi)容。所以我們應(yīng)該選擇往前看，發(fā)現(xiàn)前前句說，另一種沙漠植物被稱之為phreatophyte，他們通過長出很長的根去不斷往下穿透，到達(dá)地下水，來適應(yīng)環(huán)境。所以其實(shí)陰影部分的三種植物，都屬于phreatophyte這類植物，答案選C。
Paragraph 2: …. These products were bought mostly by urban businesses. There was also a demand among urban consumers for dairy products such as butter and cheese, which, in the sixteenth century, had become more expensive than grain. The high prices encouraged the peasants to improve their animal husbandry techniques; for example, they began feeding their animals indoors in order to raise the milk yield of their cows.
According to paragraph 2, the increases demands on Dutch agriculture made by urban consumers had which of the following results?
A.Seasonal shortages of the products consumers most wanted
B.Increased production of high-quality grain products
C.Raised prices charged by peasants to urban consumers
D.Different ways of caring for dairy-producing animals
解析：題目的提問內(nèi)容不難理解，問的是城市消費(fèi)者對(duì)荷蘭農(nóng)產(chǎn)品的需求導(dǎo)致了什么樣的結(jié)果。帶著題目內(nèi)容我們回到原文，看到了這樣一句話，There was also a demand… had become more expensive than grain。很多同學(xué)看到了這句話，然后看選項(xiàng)很容易選C。但其實(shí)C選項(xiàng)的意思跟原文還是不同的。
