Mst f us still have lts f phtgraphs sitting arund frm the days when we used cameras, nt telephnes, t take pictures. There are prbably many phts that we d nt lk at and may never see again. But these images, representing memries frm ur past, d nt have t be lst. Ggle has created a tl t help bring these frgtten pictures back t life in very high quality.
The PhtScan app wrks the same as an image scanner . But this sftware prgram uses the camera n yur phne t capture images as digital cpies, which is a quick and easy way t save ld phts withut having t spend mney n new equipment. The PhtScan app uses new technlgy t imprve the capturing prcess, which makes it pssible t take a picture f a pht with a camera phne, withut glare, a cmmn prblem.
After pening the app, the user first puts the desired pht within the camera’s frame. When this is dne, fur small circles appear in different places ver the pht. The user then mves the phne ver each f the circles, which change clr after the prcess cmpletes. That’s it! The app finds the edges f the pht, straightens the image, and puts it in the right psitin while remving glare. Frm this pint, the pictures can easily be saved t the Ggle Phts app r smewhere else. If yu d have Ggle Phts, images are rganized by face r place and can easily be fund.
The release f PhtScan came at the same time as sme changes t the Ggle Phts app. One change is an imprved aut tl that Ggle says creates high-quality effects in just ne step. Anther tl lets users chse frm 12 different lks t imprve verall pht quality. The third prvides high-level cntrls fr changing light and clrs.

In 1947, his parents lived under British clnial rule in India and were rdered t leave their hme with nly a few belngings.

Scttish summers set t keep getting warmer, study shws
Cld, wet summers culd becme a thing f the past in Sctland, accrding t a new study. Researchers frm Edinburgh and Oxfrd universities and the Met Office, the UK’s fficial weather service, say that summer temperatures f 30°C culd becme cmmn in the future because f climate change.
Climate change is lng-term changes in the wrld’s weather patterns, including rising temperatures. Human activities such as burning fssil fuels (cal, il and natural gas), farming and cutting dwn frests are a majr cause f changing weather patterns arund the wrld. When fssil fuels are burned, fr example, they release gases such as carbn dixide int the atmsphere. These gases are called greenhuse gases. Their emissins cntribute t climate change.
Peple experienced ht and dry cnditins during a heatwave in the summer f 2018. The team fund that climate change wuld lead t thse cnditins becming mre frequent in Sctland. Lead researcher Prfessr Simn Tett, frm Edinburgh University, said that carbn dixide emissins had t be cut arund the wrld in rder t prevent this frm getting wrse.
The study als lked int the direct effects f the unusual weather in 2018 n peple, animals and landscapes in Sctland. Amng these were a thirty per cent increase in demand fr water, an increase in harmful insects such as flies and msquites, and a fall in the amunt f peas, ptates, carrts and nins that were harvested. The ppulatins f sme types f birds declined because f a lack f water. There was als disturbance t trains because rails were bent by the heat.
Tett explained, “Despite its cl climate, Sctland must start t prepare nw fr the impact f high temperature extremes. The bttm line is that heatwaves have becme mre likely because f the climate change caused by human activities.”
【參考答案】

Mrever, it reveals that the dryness and htness f 2018 summer directly caused disastrus cnsequences t creatures, vegetatin and transprtatin in Sctland. Actins shuld be taken befre things get wrse. 1 a
