（2022·浙江金华·一模）①Des a lake n fire sund impssible? If yu think that water can’t burn, yu need t learn mre abut pllutin.
②Let’s g and see Bellandur Lake in the city f Bengaluru in India. Bengaluru is the center fr many heavy industries. Electrical and electrnic gds, cmputer parts and parts fr planes and space rckets are prduced there. Much f the waste frm these and a large amunt f the wastewater frm lcal peple run int the lake.
③These harmful mixed things have led the lake t becme cvered with a thick white fam (泡沫) that lks like snw when seen frm far away. When the level f the water rises, the fam des t and cvers nearby areas, even rads. When a fire breaks ut n the lake, it is bth frightening and dangerus. Peple wh live r wrk near the lake als get seriusly ill because f the pllutin.
④The fire has drawn a great deal f attentin recently, but burning lakes are nthing new. Pllutin mainly happens in develping cuntries like India tday. In the past, it mainly tk place in Eurpe and America. Cuyahga River, a river in America, had caught fire at least 13 times. The fire that caused the mst attentin was in 1969 when il-cvered areas n the river were set n fire by sparks (火花) frm a passing train. The fire reached a height f ver five flrs and burned fr abut half an hur. By that time, peple in America were mre aware f its dangers and wanted t change.

This Act required all rivers thrughut America be clean enugh t safely allw swimmers and fish t pass thrugh by 1983. Due t these effrts, the Cuyahga River has never had anther fire and ver 60 different species f fish live in the river.
⑥If histry is a guide, will it be pssible fr peple in India t bring an end t the pllutin by changing the laws in their cuntry, t? Like many natins, it’s necessary t raise awareness f envirnmental prtectin amng the general public. All f us must act!

Passage7
（2022·浙江杭州·一模）The webs that spiders build t catch insects seem weak. Hwever, the strength f spider thread is greater than steel (钢铁). Webs can even stand up t very strng strms.
In each spider web, sme threads are sticky, but sme are nt. When a spider is mving n the web, it will nt step n the sticky threads. After a time the silk will lse its stickiness and becme unable t catch insects. Then, spiders usually eat their wn web.
Nw a team f scientists has wrked ut why the spider web is s strng. It is nt just the strength f the thread, but the clever design f the web. “The key t a web’s success is its ability t keep its shape and strength even after sme f the threads break,” said scientists at the Massachusetts Institute f Technlgy (麻省理工学院). The scientists fund the thread itself has the ability t becme sfter r harder. S it can hld different types f heavy things.
In tests, scientists used three ther strng materials made int the same webs. The spider thread was six times strnger than any ther material. Mre surprisingly, when the scientists tk away up t 10 percent f the threads frm different places, the web didn’t becme any weaker. Actually, it became up t 10 percent strnger.
The spider web’s clever design gives scientists many new ideas. The findings culd help design safer buildings and even a new type f strng material. “It’s a really gd chance,” said Markus Buehler, a prfessr at MIT.” It may give us sme new ideas fr engineering.”
